Operated by The Brown Squares LLC, dba Sharpen Fitness · Version 1.1 · Effective August 31, 2026

Terms of Service

Version 1.1 · Effective August 31, 2026

Documents you accept when you agree

1. Agreement to These Terms

These Terms of Service (“Terms”) are a binding agreement between you and The Brown Squares LLC, doing business as Sharpen Fitness (“Sharpen,” “we,” “us,” or “our”), governing your use of the Sharpen 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 AND WAIVER OF LIABILITY, THE LIMITATION OF LIABILITY, AND 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.

2. Eligibility & Legal Compliance

You must be at least 18 years old 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.

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, and (on Full Access) meal-prep ideas and health tracking. It is not a medical device, healthcare provider, personal trainer, physician, or dietitian, and does not provide medical or dietetic advice.

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. 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.

6. AI-Generated Content

Workouts, plans, exercise selections, macro estimates, meal-prep ideas, equipment recognition, 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.

7. Assumption of Risk

Exercise and dietary changes carry inherent risks, including injury and, in rare cases, serious harm. YOU KNOWINGLY AND VOLUNTARILY ASSUME ALL RISKS ARISING FROM YOUR USE OF THE APP AND ANY EXERCISE OR DIETARY CHANGE, EVEN FROM ORDINARY NEGLIGENCE, AND ACCEPT RESPONSIBILITY FOR ANY RESULTING HARM.

8. Release and Waiver of Liability

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 or willful misconduct) 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 subscription: the Standard plan at $10 per month, or, if you choose it, Full Access at $20 per month. 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 health 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.

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. Except where required by law, payments are non-refundable. We may change prices with reasonable advance notice; changes take effect on the next renewal, and where required we will ask you to consent to the new price before it 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.

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 you enter (“Your Data”). You grant us a license to host, process, and use Your Data to operate and improve the App and to provide the features you use, as described in our Privacy Policy. 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

Your use is governed by our Privacy Policy and Consumer Health Data Privacy Policy on this page. You consent to our processing of your health, fitness, nutrition, movement, and location data to provide the features you use, as described in those policies. Because the App handles sensitive health information, please review those policies carefully.

19. Apple Health (HealthKit) Data

If you choose to connect the App to Apple Health, you authorize the App to read the health and fitness data you approve (such as steps and activity). We use HealthKit data only to provide App features you request. We do not use HealthKit data for advertising, marketing, or other use-based data mining, and we do not sell it or share it with third parties for those purposes. You can turn off Apple Health access at any time in your device’s Settings > Privacy & Security > Health. Our handling of this data is also described in our Privacy Policy.

20. Third-Party Services

The App relies on and may link to third-party services — for example, the Apple App Store, Apple Health, our cloud hosting and infrastructure provider, the AI provider that helps generate workouts and meal ideas, payment processing, and analytics. 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.

23. Indemnification

You agree to indemnify and hold harmless the Released Parties from claims, losses, and expenses (including reasonable legal fees) arising from your use of the App, your violation of these Terms, your violation of any law or third-party right, or your health, fitness, or dietary decisions.

24. Dispute Resolution — Informal Resolution, Arbitration & Class-Action Waiver

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.

Exceptions. Either party may bring an individual claim in small-claims court, and either party may seek injunctive relief for intellectual-property misuse.

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 this arbitration agreement within 30 days of first accepting these Terms by emailing Sharpenapp.Support@gmail.com with your name and a statement that you opt out of arbitration. Opting out does not affect any other part of these Terms.

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 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, Sharpenapp.Support@gmail.com, (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. For material changes, we will provide notice and, where appropriate, ask for your renewed acceptance. Changes take effect when posted or on the stated effective date, and your continued use after that means you accept the updated Terms.

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

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. Notices to you may be given in the App or by email; notices to us must be sent to Sharpenapp.Support@gmail.com. Section headings are for convenience only.

Privacy Policy

Effective August 31, 2026

1. Who We Are

Sharpen Fitness (“Sharpen,” “we,” “us,” or “our”) is operated by The Brown Squares LLC, 500 East McBee Ave, Suite 100 #1050, Greenville, SC 29601. This Privacy Policy explains what personal information we collect through the Sharpen mobile app (the “App”), how we use and share it, and the choices you have. Health-specific practices are described in more detail in our Consumer Health Data Privacy Policy, which supplements this Policy.

2. Information We Collect

Information you provide. Your name, email address, age, and profile details; body metrics such as height and weight; your fitness goals; workout logs; and nutrition and food logs.

Payment information. Subscriptions are billed through the Apple App Store. Apple processes your payment; we do not collect or store your full payment-card details, though we may receive limited transaction and subscription-status information.

Movement and activity data. With your permission, step counts, elevation/floors traveled, and related movement data.

Location data. With your permission, location information used to enable features such as connecting to wearables/watches and recording activity. You can control location access in your device settings.

Camera and equipment scanning. If you use the equipment-scan feature, the App accesses your camera to capture images of gym equipment so we can identify available equipment and tailor workouts. The camera is used only for this purpose when you activate it.

Apple Health (HealthKit) data. If you connect Apple Health, we read the data you approve — for example, step counts — to power App features. See Section 6.

Device and usage information. Device identifiers, app version, settings, log data, and how you interact with the App, collected to operate, secure, and improve the service.

3. How We Use Your Information

We use your information to: create and manage your account; generate workouts, plans, calorie and macro estimates, and (on Full Access) meal-prep ideas; recognize gym equipment; track your activity and progress; process your subscription; provide customer support; personalize your experience; maintain the security and integrity of the App; analyze and improve our features; and comply with legal obligations. We do not use your information for third-party advertising.

4. AI Features

Some features rely on artificial intelligence to generate workouts, plans, macro estimates, meal-prep ideas, and equipment recognition. To provide these features, relevant inputs you supply (such as your goals, metrics, logs, or equipment images) may be processed by a third-party AI provider, Anthropic, PBC (the maker of Claude), acting as our service provider. Anthropic processes this data only to provide these features on our behalf, under contractual confidentiality and security obligations that require the same or a comparable level of protection as described in this policy, and does not use it to train its models or for its own purposes. AI output is an automated estimate and may be inaccurate; it is not medical or dietetic advice.

5. How We Share Information

We do not sell your personal information, and we do not share it with third parties for their own advertising. We share information only as follows:

  • Service providers. With vendors who process data on our behalf to run the App — including Google Firebase (cloud hosting and infrastructure), Anthropic (AI features), and Apple (payments and, if you connect it, HealthKit). They may use your data only to provide services to us.
  • Legal and safety. When required by law, legal process, or to protect the rights, safety, and security of our users, the public, or Sharpen.
  • Business transfers. In connection with a merger, acquisition, financing, or sale of assets, subject to this Policy.
  • With your direction. When you ask us to share information, such as connecting a wearable device.

6. Apple Health (HealthKit)

If you enable Apple Health, we access only the categories you approve (such as steps) and use that data solely to provide the features you request. Consistent with Apple’s requirements, we do not use HealthKit data for advertising or other use-based data mining, and we do not sell it or disclose it to third parties for those purposes. You can revoke access at any time in Settings > Privacy & Security > Health.

7. Location Data

Location is collected only with your permission and used to enable features such as pairing with wearables and recording activity like distance and elevation. You can enable or disable location access at any time in your device settings; some features may not work without it.

8. Data Retention & Deletion

You can delete your account at any time using the in-app account-deletion feature. When you delete your account, we delete or de-identify your personal information within approximately three (3) months, except where we must retain limited information to comply with legal, tax, security, or dispute-resolution obligations. Backup copies are purged on our regular backup cycle.

9. Your Choices & Rights

You can review and update your profile in the App, control camera, location, motion, and Apple Health permissions in your device settings, and delete your account at any time. Depending on where you live, you may have rights to access, correct, delete, or receive a copy of your personal information, and to appeal a decision about a request. To exercise any right, contact us at Sharpenapp.Support@gmail.com. We will not discriminate against you for exercising your rights.

10. Security

We use reasonable administrative, technical, and physical safeguards designed to protect your information, including encryption in transit and access controls. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

11. Children

The App is intended for adults 18 and older. It is not directed to children, and we do not knowingly collect personal information from anyone under 18. If you believe a minor has provided us information, contact us and we will delete it.

12. U.S. Users & State Privacy Rights

The App is currently offered to users in the United States, and your information is processed and stored in the United States. Residents of certain states may have additional rights under state privacy laws (for example, to access, delete, or correct their data, and to opt out of sale or targeted advertising — which we do not engage in). To exercise these rights, contact us at the email above. Our handling of consumer health data is further described in our Consumer Health Data Privacy Policy.

13. Changes to This Policy

We may update this Policy from time to time. We will post the updated version with a new effective date and, for material changes, provide additional notice in the App. Your continued use after an update means you accept the revised Policy.

Consumer Health Data Privacy Policy

Effective August 31, 2026

1. Purpose of This Policy

This Consumer Health Data Privacy Policy explains how Sharpen Fitness, operated by The Brown Squares LLC (“Sharpen,” “we,” “us,” or “our”), collects, uses, and shares “consumer health data” — information that identifies your past, present, or future physical or mental health status. It supplements our Privacy Policy. Where a specific state law grants you greater rights, that law controls.

2. Categories of Consumer Health Data We Collect

  • Body and biometric measurements you enter, such as height and weight;
  • Fitness and exercise information, including workouts, plans, and activity logs;
  • Movement data such as step counts and elevation/floors traveled;
  • Nutrition and food logs, and calorie/macro targets and estimates;
  • Health and activity data you choose to share from Apple Health (for example, steps);
  • Your stated fitness and wellness goals; and
  • Precise or approximate location data used to record activity and connect wearables, to the extent it relates to your health or fitness.

3. Sources of This Data

We collect consumer health data directly from you when you enter it, automatically from your device and the App as you use it (with your permission), from Apple Health if you connect it, and from wearables or devices you choose to link.

4. How and Why We Use Consumer Health Data

We use consumer health data only to provide and improve the features you use: generating workouts, plans, calorie and macro estimates, and meal-prep ideas; recognizing gym equipment; tracking your activity, progress, and goals; personalizing your experience; providing support; and maintaining the security of the App. We do not use consumer health data for advertising, and we do not use it to make decisions that produce legal or similarly significant effects about you.

5. How We Share Consumer Health Data

We share consumer health data only with service providers (“processors”) who help us operate the App and who may use it only for that purpose and under contract:

  • Google Firebase — cloud hosting and infrastructure;
  • Anthropic (Claude) — to generate AI workouts, plans, meal ideas, and equipment recognition;
  • Apple — for subscription billing and, if you connect it, HealthKit access.

We may also disclose consumer health data when required by law or to protect rights and safety, or as part of a business transfer, subject to this Policy.

6. We Do Not Sell Your Consumer Health Data

We do not sell your consumer health data, and we do not exchange it for money or other valuable consideration. We will not sell consumer health data without first obtaining your valid, written authorization that meets applicable legal requirements.

7. Your Rights

Subject to applicable law, you have the right to: confirm whether we collect, share, or sell your consumer health data and access that data; withdraw consent to our collection and sharing of it; and request that we delete it. You may exercise these rights regardless of your state of residence. We will not discriminate against you for exercising them.

8. How to Exercise Your Rights & Appeal

To make a request, email us at Sharpenapp.Support@gmail.com with enough information to verify your identity and describe your request. We will respond within the timeframe required by law (generally within 45 days, with an extension where permitted). If we deny your request, you may appeal by replying to our decision or emailing the same address with the word “Appeal.” We will inform you of the outcome of your appeal and, where required, how to contact your state Attorney General.

9. Withdrawing Consent & Turning Off Collection

You can turn off camera, location, motion, and Apple Health permissions at any time in your device settings, and you can delete your account using the in-app deletion feature. Withdrawing consent or disabling permissions may limit or disable certain features.

10. Data Security & Retention

We apply reasonable safeguards to protect consumer health data, including encryption in transit and access controls. We retain consumer health data only as long as needed to provide the App and, after you delete your account, delete or de-identify it within approximately three (3) months, except where retention is legally required.

11. Changes to This Policy

We may update this Policy and will post the revised version with a new effective date. For material changes affecting consumer health data, we will provide additional notice and, where required, obtain your consent.
