Terms of Service

Version 2.0 · Effective October 12, 2026

Operated by The Brown Squares LLC Documents you accept when you agree: these Terms of Service (including the Medical & Fitness Disclaimer, the Nutrition Disclaimer, and the Assumption of Risk & Release), our Privacy Policy, and our Consumer Health Data Privacy Policy.

0. Summary and regional terms

Plain-language summary: Sharpen is an AI-powered workout and nutrition-estimate tool for healthy adults. It is not medical care. Subscriptions renew automatically through Apple until you cancel. The App is not offered in the European Economic Area, the United Kingdom, Switzerland, or mainland China. If you live outside the United States, Section 30 (Regional Terms) applies and overrides conflicting terms. Nothing in these Terms removes rights you have under the mandatory consumer laws where you live.

1. Agreement to These Terms

These Terms of Service ("Terms") are a binding agreement between you and The Brown Squares LLC ("Sharpen," "we," "us," or "our"), governing your use of the Sharpen Fit app, content, and services (the "App"). BY CHECKING "I AGREE," TAPPING A BUTTON INDICATING ACCEPTANCE, CREATING AN ACCOUNT, OR USING THE APP , YOU AGREE TO THESE TERMS, INCLUDING THE MEDICAL & FITNESS DISCLAIMER, THE NUTRITION DISCLAIMER, THE ASSUMPTION OF RISK, THE RELEASE, THE LIMITATION OF LIABILITY, AND (FOR U.S. USERS) THE ARBITRATION AGREEMENT AND CLASS-ACTION WAIVER. If you do not agree, do not use the App.

You confirm that you have had the opportunity to read these Terms and the linked documents above before agreeing, and that your acceptance is a knowing and voluntary agreement to all of them.

When you create an account, we ask for three separate choices, each shown as its own checkbox and none pre-ticked: (1) accepting these Terms and confirming that you are at least 18 and that the information you give is accurate; (2) consent to our collection and use of your health and fitness data; and (3) permission to send your inputs to our AI provider so the App can generate your content. Accepting these Terms does not by itself give choice (2) or (3). Currently, all three must be ticked to create an account, because the App's workouts, plans and estimates are built from your profile data using our AI provider. Because choices (2) and (3) are needed to provide the service, the only way to withdraw either of them is to delete your account, which you can do at any time in the App (or by emailing us at Sharpenapp.Support@gmail.com and asking us to delete it). When your account is deleted, your data is deleted as described in the Retention section of our Privacy Policy. Withdrawal does not affect processing that took place before it.

2. Eligibility & Legal Compliance

You must be at least 18 years old (or the age of majority where you live, if higher) and able to form a binding contract. Sharpen is intended for generally healthy adults. By using the App, you represent and warrant that (a) you are not located in a country subject to a U.S. Government embargo or designated by the U.S. Government as a "terrorist supporting" country, and (b) you are not listed on any U.S. Government list of prohibited or restricted parties. You agree to comply with all applicable laws when using the App.

Where the App is offered. We offer the App only in the App Store storefronts where it is listed the United States, Canada, Latin America, the Asia-Pacific region (including Australia, Japan, Korea and India), and Africa and the Middle East. We do not make the App available in the App Store storefronts for the European Economic Area (EU member states, Iceland, Liechtenstein and Norway), the United Kingdom, Switzerland or mainland China. The App is not directed to residents of those territories, and we do not market it there. If you reside in one of those territories, please do not create an account.

3. What the App Is — and Is Not

Sharpen provides general fitness tools, exercise demonstrations, workout tracking, automatically calculated estimates of calorie and macro targets, step counts from your device's motion sensor, and (on Full Access) meal-prep ideas and progress tracking. It is an AI-powered workout coach for general wellness. It is not a medical device, healthcare provider, certified or licensed personal trainer, physician, or dietitian, and does not provide medical or dietetic advice. It is not intended to diagnose, treat, cure, mitigate, or prevent any disease, injury, or condition, or to guide rehabilitation.

4. Medical & Fitness Disclaimer

Content is for general information only and is not a substitute for professional medical advice, diagnosis, or treatment. CONSULT YOUR PHYSICIAN BEFORE BEGINNING ANY EXERCISE OR NUTRITION PROGRAM, ESPECIALLY IF YOU HAVE A MEDICAL CONDITION OR INJURY, ARE PREGNANT OR NURSING, OR TAKE MEDICATION. If you feel pain, dizziness, or any concerning symptom, stop and seek medical attention.

In an emergency, call your local emergency number. You are responsible for exercising safely and within your abilities.

5. Nutrition & Calorie/Macro Disclaimer

Calorie and macro targets, and any meal-prep ideas, are automatically generated estimates based only on the information you enter, using standard formulas. They are informational estimates, not medical or dietetic advice, and not a prescription. Consult a professional before changing your diet, especially with any medical condition or a history of disordered eating. Do not pursue extreme calorie restriction.

Daily calorie targets set by the App will not be below 1,200 kcal if you selected female, or 1,500 kcal if you selected male or did not specify your sex. These targets are calculated by a standard formula (Mifflin-St Jeor) and the minimum is applied in our software; the AI does not set your calorie number. This minimum is a general limit, not medical advice or a guarantee that a target is safe for you; consult a qualified professional before any calorie-restricted diet.

If you are struggling with disordered eating or your relationship with food, please seek support from a qualified professional; in the United States you can contact the National Alliance for Eating Disorders helpline at 1-866-662-1235.

For other countries, please contact a local eating-disorder helpline.

6. AI-Generated Content

Workouts, plans, exercise selections, macro estimates, meal-prep ideas, equipment recognition, food-photo analysis, and other content are generated in part by automated / AI systems (including third-party AI services) and may be inaccurate, incomplete, or unsuitable for you. Use your own judgment and verify important information. Weights, paces, and macros are suggestions, not prescriptions. AI output is labelled in the App. AI can "hallucinate" exercises, loads or nutrition values. Never perform a movement you are unsure about. Equipment recognition may misidentify equipment; check equipment is safe and set up correctly before use.

7. Assumption of Risk

Exercise and dietary changes carry inherent risks, including injury and, in rare cases, serious harm. YOU KNOWINGLY AND VOLUNTARILY ASSUME THE INHERENT RISKS OF EXERCISE OR DIETARY CHANGE TO THE EXTENT PERMITTED BY APPLICABLE LAW .

8. Release and Waiver of Liability

IF YOU ARE A U.S. RESIDENT, TO THE FULLEST EXTENT PERMITTED BY LAW , YOU RELEASE AND AGREE NOT TO SUE THE RELEASED PARTIES (the company, its owners, officers, employees, contractors, and affiliates) FOR ANY CLAIMS ARISING FROM YOUR USE OF THE APP OR ANY EXERCISE OR DIETARY CHANGE, INCLUDING INJURY, ILLNESS, OR DEATH. This does not apply to liability that cannot be waived under law (such as gross negligence, willful misconduct, fraud, or, where the law so provides, death or personal injury caused by negligence) or to non-waivable consumer rights.

9. No Guarantee of Results

We provide tools, not promised outcomes. We do not guarantee any fitness, weight, health, or performance result. Results depend on factors outside our control, and you may experience no change. A lack of results is not a basis for any claim.

10. Your License to Use the App

Subject to these Terms, we grant you a personal, limited, non-exclusive, non- transferable, revocable license to use the App for your own personal, non-commercial use. For Apps obtained through the Apple App Store, this license is limited to use on any Apple-branded products that you own or control and as permitted by the App Store Usage Rules in the Apple Media Services Terms and Conditions. You may not sell, rent, sublicense, distribute, copy, modify, reverse-engineer, decompile, or create derivative works from the App except to the extent this restriction is prohibited by applicable law.

11. Subscriptions, Free Trial & Auto-Renewal

New members receive a 7-day free trial with full access. Unless you cancel at least 24 hours before the trial ends, your membership automatically converts to a paid, auto- renewing monthly subscription to the plan you select, at the price shown in the App Store for your country and currency (currently in the U.S.: Standard US$9.99 per month; Full Access US$19.99 per month). There is no annual plan. The Standard plan lets you generate workouts and build a plan; Full Access includes everything in Standard and adds AI meal-prep ideas targeted to your goals and progress tracking.

This is a recurring subscription. Payment is charged to your Apple ID account at confirmation of purchase, and the subscription renews automatically each month at the then-current price unless you cancel. Your account is charged for renewal within 24 hours before the end of the current period. Any unused portion of a free trial is forfeited when you purchase a subscription.

Before you start a trial we show you the price, billing period, the date your trial converts, and how to cancel. Where required by law, we (or Apple) will remind you before your trial ends and before renewals. App Store subscriptions can only be cancelled in your Apple ID subscription settings. Tap Settings → Manage Subscription in the App to open them directly. Our support team can't cancel an App Store subscription for you, but will walk you through it. If we ever sell subscriptions on our website, you will be able to cancel online immediately with a clearly labelled cancel button.

12. Cancellation, Refunds & Price Changes

You may cancel any time in your Apple App Store account settings; cancellation takes effect at the end of the current billing period, and you keep access until then. Because billing is handled by Apple, subscriptions cannot be canceled directly through us, and refunds are handled under Apple's policies; you can request a refund at reportaproblem.apple.com. Except where required by law, payments are non- refundable. We may change prices with reasonable advance notice; changes take effect on the next renewal, where required we will ask you to consent to the new price before it applies, and you may cancel before the new price applies.

13. Your Account

You are responsible for your account, your credentials, and all activity under your account. Provide accurate information, keep your password secure, and notify us promptly of any unauthorized use. You may not share your account or let others use it.

You can delete your account at any time in the App; deletion removes your account record from our servers as described in our Privacy Policy.

14. Acceptable Use

You agree not to: misuse, disrupt, or interfere with the App or its security; access the App by unauthorized means or through automated scraping; reverse-engineer or attempt to extract source code except where permitted by law; upload malicious code; use the App for any unlawful purpose; or infringe the rights of others. We may suspend or terminate access for conduct that violates these Terms.

15. Intellectual Property

The App and its content — including software, text, graphics, exercise demonstrations, and trademarks — are owned by us or our licensors and protected by intellectual- property law. Except for the limited license in Section 10, no rights are granted to you.

"Sharpen" and our logos may not be used without our prior written permission.

16. Your Content & Data You Enter

You retain ownership of the workout, body, nutrition, and profile information and the photos you enter ("Your Data"). You grant us a license to host, process, and use Your Data solely to operate, secure, and improve the App and to provide the features you use, as described in our Privacy Policy. This license ends when you delete Your Data or your account, except for backups retained as described in the Privacy Policy. We do not train any AI models on Your Data, and our AI provider may not use it to train its models. You are responsible for the accuracy of the information you enter, and you represent that you have the right to provide it.

17. Feedback

If you send us suggestions, ideas, or feedback about the App, you agree we may use them without restriction or obligation to you, and you grant us a perpetual, irrevocable, royalty-free license to use them for any purpose.

18. Privacy & Health Data

Our Privacy Policy and Consumer Health Data Privacy Policy explain how we handle your data. Because the App handles health information, please review those policies carefully. We collect and use consumer health data only with the separate health-data consent you give at sign-up, which you can withdraw as described in Section 1 and our Privacy Policy, without affecting the lawfulness of prior processing. We do not sell your health data or use or share it for advertising. The App contains no analytics, crash- reporting, attribution or advertising SDKs. If we change how we use or share health data you have already given us in a material way, we will ask for your consent first.

19. Apple Health

The App does not read from or write to Apple Health (HealthKit). If a future version uses Apple Health, we will update these Terms and our Privacy Policy and ask for your permission before accessing any Apple Health data.

20. Third-Party Services

The App relies on and may link to third-party services — for example, the Apple App Store, our cloud hosting and database provider, the AI provider that helps generate workouts, meal ideas and photo analysis, our subscription-management, push- notification and email providers, and payment processing through Apple. We are not responsible for third-party services, and your use of them is governed by their own terms and privacy policies. You must comply with any applicable third-party terms of agreement when using the App.

21. Disclaimer of Warranties

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND TO THE MAXIMUM EXTENT PERMITTED BY LAW , INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ACCURACY. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE. Some jurisdictions do not allow the exclusion of certain warranties, so some of these exclusions may not apply to you.

22. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY LAW , THE RELEASED PARTIES ARE NOT LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS OR DATA, AND THEIR TOTAL LIABILITY WILL NOT EXCEED THE GREATER OF WHAT YOU PAID US IN THE PRIOR 12 MONTHS OR US $100. Some jurisdictions do not allow certain limitations, so some of these limitations may not apply to you. Nothing in these Terms limits liability that cannot be limited under applicable law. The cap and exclusions in this Section do not apply to (a)

death or personal injury caused by our negligence, (b) fraud or fraudulent misrepresentation, (c) gross negligence or willful misconduct, or (d) any liability that cannot be limited under applicable law, including statutory consumer guarantees (e.g., under the Australian Consumer Law, which we limit only to the extent the law allows, such as by resupplying the service or paying for it to be resupplied).

23. Indemnification

You agree to indemnify and hold harmless the Released Parties from claims, losses, and expenses (including reasonable legal fees) arising from your misuse of the App, your violation of these Terms, or your violation of any law or third-party right. This Section does not apply to consumers in jurisdictions where such indemnities are unenforceable (including Australia and Quebec).

24. Dispute Resolution for U.S. Users — Informal Resolution,

Arbitration & Class-Action Waiver This Section 24 applies only if you reside in the United States. Please read this section carefully — it affects how disputes are resolved and may limit your right to go to court or participate in a class action.

Governing law. These Terms are governed by the laws of the State of South Carolina, without regard to conflict-of-law rules, except where preempted by the Federal Arbitration Act or superseded by mandatory local consumer-protection law.

Informal resolution first. Before starting an arbitration, you agree to contact us at Sharpenapp.Support@gmail.com and give us 30 days to try to resolve the dispute informally.

Binding arbitration. If we cannot resolve the dispute, it will be resolved by binding individual arbitration administered by the American Arbitration Association (AAA)

under its Consumer Arbitration Rules, in Greenville County, South Carolina, or by videoconference where available, rather than in court, except as noted below. If 25 or more similar demands are filed by the same or coordinated counsel, the AAA Mass Arbitration Supplementary Rules apply.

Exceptions. Either party may bring an individual claim in small-claims court, and either party may seek injunctive relief for intellectual-property misuse. Claims for public injunctive relief, where the law does not allow them to be waived, will be decided in court after any individual arbitration, and are not subject to the class-action waiver to that extent.

Class-action waiver. YOU AND WE AGREE TO BRING CLAIMS ONLY INDIVIDUALLY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING, WHERE PERMITTED BY LAW .

Opt-out. You may opt out of arbitration by emailing Sharpenapp.Support@gmail.com with your name, account email, and a statement that you opt out, within 30 days after you first accept these Terms. Opting out does not affect any other part of these Terms.

Existing users may opt out of changes to this Section within 30 days after version 2.0 takes effect, by the same method; doing so keeps you under the prior version of this Section. Even if you opt out of these changes, Section 24 applies only to U.S. residents, and the public-injunctive-relief sentence above still applies.

25. Apple App Store Terms

These terms apply when you obtain the App through the Apple App Store, and are in addition to the rest of these Terms:

This agreement is with us, not Apple. These Terms are between you and The Brown Squares LLC only, and not with Apple Inc. ("Apple"). Apple is not responsible for the App or its content.

Scope of license. Your license to use the App is limited to a non-transferable license to use it on any Apple-branded products that you own or control, as permitted by the App Store Usage Rules.

Maintenance and support. We, not Apple, are solely responsible for providing any maintenance and support for the App. Apple has no obligation to furnish any maintenance or support services.

Warranty. We are solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. If the App fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price (if any) for the App; to the maximum extent permitted by law, Apple will have no other warranty obligation with respect to the App.

Product claims. We, not Apple, are responsible for addressing any claims relating to the App, including product-liability claims, claims that the App fails to conform to any applicable legal or regulatory requirement, and claims under consumer-protection, privacy, or similar law.

Intellectual property claims. If a third party claims the App infringes its intellectual- property rights, we, not Apple, will be solely responsible for the investigation, defense, settlement, and discharge of any such claim.

Legal compliance. You represent that you are not located in a country subject to a U.S.

Government embargo or designated as a "terrorist supporting" country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.

Developer contact. Questions, complaints, or claims about the App should be directed to The Brown Squares LLC, 500 East McBee Ave, Suite 100 #1050, Greenville, SC 29601, United States, Sharpenapp.Support@gmail.com, phone (864) 795-6160.

Third-party terms. You must comply with any applicable third-party terms of agreement when using the App.

Third-party beneficiary. Apple and its subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, will have the right to enforce these Terms against you.

26. Changes to These Terms

We may update these Terms from time to time. We will give at least 30 days' notice of material changes in the App or by email. Changes won't apply retroactively. If you do not agree, you may cancel and delete your account before they take effect. Where the law requires your express agreement, we will ask for it.

27. Termination

You may stop using the App and delete your account at any time. We may suspend or terminate your access if you violate these Terms or to comply with law. Upon termination, your license ends, but the disclaimers, releases, assumption of risk, limitation of liability, indemnity, and dispute-resolution terms survive.

28. General Provisions & Notices

These Terms and the documents incorporated by reference are the entire agreement between you and us regarding the App. If any provision is held unenforceable, the rest remains in effect, and the unenforceable provision will be limited or removed to the minimum extent necessary. Our failure to enforce any provision is not a waiver. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets. We are not liable for delays or failures caused by events beyond our reasonable control. Section headings are for convenience only.

Notices. Notices to you may be given in the App or by email. Notices to us must be sent to Sharpenapp.Support@gmail.com or by mail to The Brown Squares LLC, 500 East McBee Ave, Suite 100 #1050, Greenville, SC 29601, United States. Service of legal process on The Brown Squares LLC must be made on its registered agent: Northwest Registered Agent, LLC, 6650 Rivers Ave STE 100, Charleston, SC 29406, United States.

For questions you may also call us at (864) 795-6160; telephone contact does not replace written notice.

Privacy Policy

Version 2.0 · Effective October 12, 2026

1. Who we are

The Brown Squares LLC ("Sharpen Fit", "we"), 500 East McBee Ave, Suite 100 #1050, Greenville, SC 29601, United States, is responsible for your personal data. Contact:

Sharpenapp.Support@gmail.com. - Person responsible for privacy / person in charge of the protection of personal information (Quebec) / Encarregado (Brazil) / Chief Privacy Officer (Korea) / Grievance Officer (India): the Privacy Contact at Sharpenapp.Support@gmail.com The App is not offered in the European Economic Area, the United Kingdom, Switzerland, or mainland China.

2. Summary

We use your data to build workouts and nutrition estimates. We don't sell it or use it for ads, and the App contains no analytics, crash-reporting, attribution or advertising SDKs.

At sign-up we ask for three separate choices, none pre-ticked: agreeing to our Terms (and confirming you are 18+ and your information is accurate), consenting to the collection and use of your health and fitness data, and permitting your inputs to be sent to our AI provider (Anthropic). Agreeing to the Terms does not give the other two. Currently all three are required to create an account, and the health-data and AI consents can be withdrawn only by deleting your account.

The App does not use Apple Health, wearables, or location.

Your data is processed and stored in the United States.

You can delete your account in the App at any time.

3. Data we collect

- Account — name, email, password (stored only as a salted hash). Source: you. Required: yes.

- Profile & goals — age, sex, height, weight, fitness goals, experience, equipment. Source: you. Required: yes.

- Health & fitness data — height, weight, workout logs, nutrition/food logs, calorie/macro targets. Source: you. Required: yes, with your health-data consent.

- Step and motion counts — step counts from your device's motion sensor. Source: your device. Optional (you can decline the iOS Motion & Fitness permission without blocking the App).

- Camera images — photos of gym equipment when you use Scan, and photos of meals when you log food by photo (food photos can reveal diet or health information and are treated as health data). Source: you. Optional, when you use those features. Please avoid photographing other people. - Subscription — plan, trial status, transaction IDs (no card data). Source: Apple, RevenueCat. Required: yes, if subscribing.

- Device & service data — device model, OS, app version, push-notification token, server logs. Source: automatically. Required: yes.

- Support — messages you send us. Source: you. Optional.

We do not collect sleep, menstrual-cycle, symptom, medication or heart-rate data. The App does not read from or write to Apple Health (HealthKit), does not connect to wearables, and does not access your location. If a future version uses Apple Health or another new data source, we will update this Policy and ask for your permission before collecting that data.

We do not knowingly collect data from anyone under 18.

4. How we use data

- Create and run your account; provide workouts, plans and estimates — uses account, profile, health & fitness data.

- Send your inputs to our AI provider to generate content and recognise equipment and food — uses profile, goals, metrics, logs, equipment photos, food photos.

- Subscriptions and billing records — uses subscription data.

- Security, fraud prevention, debugging — uses device & service data.

- Support and service messages (including transactional email and push notifications) — uses account and support data.

- Legal compliance and claims — as needed.

We do not use your data for advertising, sell it, or "share" it for cross-context behavioural advertising. We do not make decisions that produce legal or similarly significant effects about you solely by automated means. AI-generated plans are suggestions you control.

5. Your consent choices

At sign-up we show three separate, unticked checkboxes: (a) agreement to our Terms and this Policy, and confirmation that you are 18 or older and that your information is accurate; (b) consent to collect and use your health and fitness data; and (c) permission to share your inputs (including profile, goals, logs, equipment photos and food photos)

with our AI provider, Anthropic, PBC (USA), to generate content. Each must be ticked separately; none is pre-ticked and none is bundled with another. Currently all three are required to create an account, because the App builds your plans from this data using Anthropic. Because consents (b) and (c) are needed to provide the service, the only way to withdraw either of them is to delete your account, which you can do at any time in the App (or by emailing Sharpenapp.Support@gmail.com and asking us to delete it).

Your data is then deleted as described in §9 (Retention). Withdrawing doesn't affect prior processing. You can also revoke camera and motion permissions in iOS Settings.

6. AI features

Inputs needed for a feature are sent to Anthropic, PBC (USA), acting as our processor under Anthropic's Commercial Terms of Service, which incorporate its Data Processing Addendum. Anthropic may not train models on your data. We do not train any AI models on your data. Equipment and food photos are sent to Anthropic only within the request for analysis; we do not store them, and we do not upload them to Anthropic's file storage (Files API). Anthropic automatically deletes API inputs and outputs within 30 days under its standard API terms, except that content flagged by its automated trust and safety systems as violating its Usage Policy may be kept for up to 2 years, and data may be kept longer where the law requires (e.g., legal holds). We do not have a Zero Data Retention agreement with Anthropic. AI output is an automated estimate, may be inaccurate, and is not medical or dietetic advice.

7. Who we share data with

We share data only with service providers (processors) that act on our instructions under contract and may use it only to provide services to us:

- Anthropic, PBC (USA): AI generation and photo analysis.

- Render: application hosting and database.

- RevenueCat: subscription management.

- Apple: App Store billing and in-app purchases (Apple also acts under its own privacy policy).

- Expo: push-notification delivery.

- Resend: transactional email.

- Google Firebase: hosting of our public website and legal pages only. No App user data is stored in Firebase.

We also disclose data for legal and safety reasons, and in business transfers (the successor must honour this Policy).

The App contains no analytics, crash-reporting, attribution or advertising SDKs. A current list of processors is available on request.

8. International transfers

We are based in the US and process and store data there. If you use the App from outside the US, your data is transferred to the US. For Brazil, we use ANPD standard contractual clauses (Res. CD/ANPD 19/2024). For Japan, Korea, Canada (including Quebec), Australia and India, we provide this notice and rely on contractual safeguards with our processors and, where required, your consent. Copies of safeguards:

Sharpenapp.Support@gmail.com.

9. Retention

- Account, profile, health & logs — life of account. When you delete your account, your account record is removed from our servers, and remaining data is deleted or de-identified within 90 days.

- Equipment and food photos — by us: not stored; processed only within the AI request. By Anthropic: up to 30 days under standard API terms; up to 2 years if flagged for a Usage Policy violation; longer if required by law. - Backups — overwritten within 35 days after deletion from production.

- Subscription/tax records — 7 years or as required by law.

- Security logs — 12 months.

- Consent records — life of account plus the applicable limitation period.

10. Your rights

Depending on where you live, you may have the right to: access/know; correct; delete; port; object; withdraw consent; appeal a refusal; and know the third parties we share with. Anyone can use these rights by using in-app deletion or emailing Sharpenapp.Support@gmail.com. We verify your identity and respond within the legal deadline (e.g., 45 days under US state laws, 30 days under Quebec law, 15 days under LGPD for confirmation, 10 days under PIPA). We will not discriminate against you for exercising your rights. Complaints: You may complain to your local regulator, e.g., the Office of the Privacy Commissioner of Canada or Quebec's Commission d'accès à l'information, the OAIC (Australia), the ANPD (Brazil), the PPC (Japan), the PIPC (Korea), or the Data Protection Board of India. US residents may appeal to us and then contact their state Attorney General.

11. Security

Encryption in transit and at rest, passwords stored only as salted hashes, access controls, least-privilege staff access, vendor due diligence. If a breach affects your data, we will notify you and the authorities as the law requires (including the U.S. FTC Health Breach Notification Rule and equivalent laws).

12. Children

18+ only. We delete data we learn belongs to a minor.

13. U.S. state notices

California and other state privacy laws: categories of personal information as in §3. Sensitive personal information (health data) is used only to provide the services you request, consistent with Cal. Code Regs. tit. 11 §7027(m). No sale or sharing. No financial incentives.

Washington, Nevada, Connecticut consumer health data: see our Consumer Health Data Privacy Policy.

Nevada: We do not sell covered information (NRS 603A.320) and honor requests under NRS 603A.345 at Sharpenapp.Support@gmail.com. We do not sell consumer health data (Nevada SB 370, NRS 603A.400–.550).

14. Regional supplements

Consumer Health Data Privacy Policy

Version 2.0 · Effective October 12, 2026

1. Purpose of this Policy

This Consumer Health Data Privacy Policy explains how The Brown Squares LLC ("Sharpen Fit", "we", "us" or "our") collects, uses, shares and deletes "consumer health data", meaning personal information that is linked or reasonably linkable to you and that identifies your past, present or future physical or mental health status. It applies to the Sharpen Fit app (the "App") and supplements our Privacy Policy. It is written to meet the Washington My Health My Data Act (RCW 19.373), Nevada's consumer health data law (SB 370, NRS 603A.400–.550) and Connecticut's consumer health data provisions (Conn. Gen. Stat. §42-515 et seq.). Where a law gives you greater rights, that law controls.

2. Categories of consumer health data we collect

Body measurements you enter: age, sex, height and weight.

Fitness and exercise information: workouts, plans and workout logs.

Step and motion counts from your device's motion sensor.

Nutrition and food logs, including food photos (which may reveal diet or health information), and calorie and macro targets and estimates.

Your stated fitness and wellness goals.

Information we derive from the above, such as calorie and macro estimates and generated workout and meal plans.

We do not collect sleep, menstrual-cycle, symptom, medication or heart-rate data. The App does not read from or write to Apple Health (HealthKit), does not connect to wearables and does not access your location. The App contains no analytics, crash- reporting, attribution or advertising SDKs. If a future version uses a new data source, we will update this Policy and ask for your consent before collecting that data.

3. Sources

We collect consumer health data directly from you when you enter it or take a photo in the App, and from your device's motion sensor (with your permission).

4. How and why we use consumer health data

We use consumer health data only to provide the features you request: generating workouts, plans, calorie and macro estimates and meal ideas; recognising gym equipment and food from photos; tracking your activity, progress and goals; providing support; and keeping the App secure. We do not use consumer health data for advertising, we do not sell it, and we do not use it to make decisions that produce legal or similarly significant effects about you. We do not train AI models on your data.

5. Consent

We collect consumer health data only with your consent, and share it (beyond what is necessary to provide the service you requested) only with your separate consent. At sign-up we show three separate, unticked checkboxes: agreement to our Terms and Privacy Policy; consent to collect and use your health and fitness data; and permission to send your inputs (including profile, goals, logs, equipment photos and food photos)

to our AI provider, Anthropic. Health-data consent is not bundled with the Terms.

Currently all three are required to create an account. You can withdraw your health- data consent at any time by deleting your account in the App (or by emailing us at Sharpenapp.Support@gmail.com and asking us to delete it); we then delete your consumer health data as described in Section 11.

6. How we share consumer health data

We share consumer health data only with service providers (processors) that act on our instructions under contract and may use it only to provide services to us: - Anthropic, PBC (USA): AI generation and analysis of equipment and food photos. Inputs, including equipment and food photos, are sent to Anthropic within the request for analysis; we do not store the photos. Anthropic may not train models on your data and retains inputs for up to 30 days under its standard API terms (longer for content flagged for policy violations, up to 2 years, or where legally required). - Render (USA): application hosting and database. - RevenueCat (USA): subscription management. - Apple: billing. - Expo (USA): push-notification delivery. - Resend (USA): email delivery.

Of these, Anthropic and Render receive consumer health data; RevenueCat and Apple receive subscription data only. Push-notification and email content sent through Expo and Resend does not contain consumer health data. Google Firebase hosts only our public website and receives no consumer health data. A list of all third parties and affiliates with whom we share consumer health data, with their contact information, is available on request.

We may also disclose consumer health data where required by law or to protect rights and safety, or as part of a merger, acquisition or sale of assets, subject to this Policy.

7. We do not sell consumer health data

We do not sell consumer health data or exchange it for money or other valuable consideration, and we do not use it for targeted advertising. We would not sell it without first obtaining your valid written authorization meeting the requirements of applicable law.

8. No geofencing

We do not implement geofences around facilities that provide in-person health care services. The App does not access your location.

9. Your rights

Whatever state you live in, you may: - confirm whether we collect, share or sell your consumer health data, and access it, including a list of all third parties and affiliates with whom we have shared it, with their contact information; - withdraw your consent to our collection and sharing of it (by deleting your account, see Section 5); and - have it deleted. When you delete your account or ask us to delete your data, we delete it from our records and notify our processors to delete it; data in archived or backup systems is deleted within 6 months.

We will not discriminate against you for exercising these rights.

10. How to exercise your rights, authorised agents and appeals

Requests: use in-app account deletion or email Sharpenapp.Support@gmail.com with enough information for us to verify your identity and describe your request.

We will verify your identity using information we already hold, and we will not ask you to create a new account.

Authorised agents: where your law allows (for example, Connecticut), an agent you authorise may make a request on your behalf. We may ask for your signed permission and may verify your identity directly with you.

Response time: within 45 days of receiving your request, extendable once by a further 45 days when reasonably necessary. If we extend, we will tell you why within the first 45 days. Requests are free of charge.

Appeals: if we decline your request, you may appeal by replying to our decision or emailing Sharpenapp.Support@gmail.com with the subject "Appeal". We will respond in writing within 45 days (60 days where Connecticut law applies), explaining our decision. If we deny your appeal, you may contact your state Attorney General: the Washington, Nevada or Connecticut Attorney General's office.

11. Security and retention

We use reasonable safeguards to protect consumer health data, including encryption in transit and at rest, access controls and least-privilege staff access. Your data is processed and stored in the United States. We keep consumer health data for the life of your account. When you delete your account, your account record is removed from our servers, and remaining data is deleted or de-identified within 90 days, except where retention is legally required.

12. Changes

We will post updates with a new effective date and give notice in the App of material changes at least 30 days in advance. Where the law requires, we will ask for your consent before collecting or sharing consumer health data under the revised Policy.
