Terms of Use

MassFrame · Effective 28 September 2026

1. Parties and contact

These Terms of Use (the "Terms") form a binding agreement between you and Baston Apps ("we", "us", "our"), an independent software developer established in Türkiye, governing your use of the MassFrame application for iOS (the "Application").

Notices and enquiries may be sent to support@bastonapps.com.

2. Acceptance and eligibility

By downloading, installing, or using the Application you accept these Terms in full. If you do not accept them, do not use the Application and delete it from your device.

You must be at least 13 years old, or at least 16 if you are in the European Economic Area, to use the Application. If you are below the age of majority where you live, you confirm that your parent or legal guardian has reviewed and agreed to these Terms on your behalf.

3. Relationship to Apple's agreements

The Application is licensed, not sold, and is distributed through the Apple App Store. Apple's Licensed Application End User License Agreement (the "Apple EULA") applies to your use of the Application. These Terms are supplementary to the Apple EULA. To the extent of any conflict between these Terms and the Apple EULA, the Apple EULA prevails.

These Terms are concluded between you and us only, and not with Apple. Apple is not responsible for the Application or its contents, save as set out in these Terms and the Apple EULA.

4. Licence

Subject to your compliance with these Terms, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable and revocable licence to install and use the Application on any Apple-branded device that you own or control, as permitted by the Usage Rules set out in the Apple Media Services Terms and Conditions.

You may not, and may not permit any third party to:

1. copy, modify, adapt, translate, or create derivative works of the Application, except as permitted by mandatory applicable law;
2. reverse engineer, decompile, or disassemble the Application, or otherwise attempt to derive its source code, except to the extent that such restriction is prohibited by mandatory applicable law;
3. rent, lease, lend, sell, redistribute, sublicense, or commercially exploit the Application;
4. circumvent, disable, or interfere with any access control, entitlement check, or other technical measure that restricts features to those who have purchased them;
5. use the Application in any manner that violates applicable law or infringes the rights of any third party.

5. Description of the Application

The Application is a training notebook. It records your gym sessions, sets and personal records, your bodyweight and body-composition figures, notes, progress and meal photographs, and the training plans you adopt or build, and it keeps all of this in a database on your device. It can read from and write to Apple Health with your permission, schedule reminders on your device, and work out figures such as estimated one-repetition maximums, body-fat percentage, lean mass, a fat-free mass index, and daily energy and protein targets from the numbers you supply.

On request, and after you have agreed to it in the Application, it can send one front-on photograph and four figures to a machine-learning model to be read for visible muscular development, and can send the same photograph and your body-composition figures to a model that draws a picture of how you may look six months on; and it can send a photograph of a meal to be read for the foods in it and their estimated energy and macronutrients. How this works, what is sent and what is kept is set out in our Privacy Policy.

The Application maintains no account and operates no synchronisation service. It keeps one copy of your notebook, on your device; you are responsible for your device's backups.

6. Price

The Application is currently offered without charge, and nothing in it is for sale. If paid features are introduced, their price, duration and renewal terms will be shown in the Application before any purchase, these Terms will be updated before they are offered, and purchases will be made from Apple, with billing, payment and refunds handled by Apple under its terms. No amount will ever be charged without your confirmation.

7. Open-source software

The Application includes the following open-source software, each used under the MIT License, whose notice is reproduced below as that licence requires:

• GRDB.swift — Copyright (C) 2015-2025 Gwendal Roué.
• RevenueCat purchases-ios — Copyright (c) 2024 RevenueCat, Inc.

Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software. THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.

These licences apply to those components only; the rest of the Application is licensed to you under clause 4.

8. Apple Health

Where you permit it, the Application reads body mass, body-fat percentage, active energy, height, date of birth and biological sex from Apple Health, and writes to Apple Health a workout when you stamp a session as completed and, if you switch them on, the weights you type and the meals it reads. Data obtained from Apple Health is used only for the purposes described in the Privacy Policy, is never used for advertising or sold, and leaves your device only as the Privacy Policy describes — with a progress photograph you ask to have read, after your explicit consent. You may change or withdraw these permissions at any time in iOS Settings, and the Application continues to work without them.

9. Training, health and safety

The Application is a record of what you did. It is not a coach, a trainer, a dietitian or a doctor, and nothing in it is medical advice. Training plans supplied with the Application are general templates, not programmes prescribed for you. Estimated one-repetition maximums, body-fat percentage, lean mass, the fat-free mass index and its bands, the six-month projection, the physique reading, the six-month picture, meal readings, and the energy and protein targets are estimates and illustrations produced from numbers you supplied, by population formulas or by a machine-learning model, and can be wrong. The picture in particular is a machine's drawing from your photograph and your figures, and is not a prediction or a promise of any outcome. A meal reading is an estimate from a photograph, which cannot weigh anything, and the targets are a starting point, not a diet prescribed for you.

You are solely responsible for deciding whether and how to train, for the loads, movements and equipment you use, for your diet, and for seeking medical advice before beginning or changing a programme or your diet, particularly if you have a medical condition, a history of disordered eating, or are pregnant. Resistance training carries a risk of injury. You assume all risk arising from your training and from any use you make of the figures, readings and pictures the Application shows you.

10. Your content

Everything you write in the notebook, and every photograph you put in it, is yours. We claim no rights over it. You are responsible for the photographs you take or import, including for having the right to use any photograph of another person, and for what you choose to send for a reading or a picture. Progress photographs sent for a reading or a picture must be of yourself, an adult, and must not be of anyone else.

11. Intellectual property

The Application, including its software, design, artwork, the training plans it supplies, and the Baston Apps and MassFrame names, is owned by us and protected by intellectual property laws. Except for the licence granted in clause 4, no right, title, or interest is transferred to you.

12. Maintenance and support

We are solely responsible for providing any maintenance and support services in respect of the Application, as specified in these Terms or as required by applicable law. Apple has no obligation whatsoever to furnish any maintenance or support services in respect of the Application.

13. Disclaimer of warranties

To the maximum extent permitted by applicable law, the Application is provided "as is" and "as available", without warranty of any kind, whether express, implied, or statutory, including any implied warranty of merchantability, fitness for a particular purpose, accuracy, or non-infringement. We do not warrant that the Application will be uninterrupted, error-free, or that any reading, picture or figure it produces is accurate.

The physique reading and the six-month picture depend on a third-party model service, and so do meal readings. They may be unavailable, may decline a photograph, and may be changed or withdrawn; the Application continues to work without them.

In the event of any failure of the Application to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the Application to you, if any. To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the Application, and any other claims, losses, liabilities, damages, costs, or expenses attributable to any failure to conform to any warranty will be our sole responsibility.

14. Limitation of liability

To the maximum extent permitted by applicable law, we shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, revenue, data, goodwill, or business opportunity, arising out of or in connection with your use of or inability to use the Application, whether based in contract, tort, strict liability, or otherwise, and whether or not we have been advised of the possibility of such damages.

To the maximum extent permitted by applicable law, our aggregate liability arising out of or in connection with the Application shall not exceed the greater of the amount you paid to Apple for the Application and any subscription in the twelve months preceding the event giving rise to the liability, or ten euros (€10).

Nothing in these Terms excludes or limits our liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot be excluded or limited under applicable law.

15. Consumer rights

Where you use the Application as a consumer, you benefit from mandatory provisions of the law of the country in which you reside. Nothing in these Terms affects your rights as a consumer to rely on those mandatory provisions, including, for residents of Türkiye, rights under the Law on Consumer Protection No. 6502, and, for residents of the European Economic Area and the United Kingdom, statutory rights in respect of digital content and services.

16. Indemnity

To the extent permitted by applicable law, you agree to indemnify and hold us harmless from any claim, demand, loss, or expense, including reasonable legal fees, arising from your breach of these Terms, your misuse of the Application, or your infringement of the rights of a third party. This clause does not apply to the extent that a claim arises from our own breach or negligence.

17. Product claims

We, and not Apple, are responsible for addressing any claims by you or any third party relating to the Application or your possession and use of it, including product liability claims, any claim that the Application fails to conform to any applicable legal or regulatory requirement, and claims arising under consumer protection, privacy, or similar legislation.

18. Intellectual property claims

In the event of any third-party claim that the Application or your possession and use of it infringes that third party's intellectual property rights, we, and not Apple, will be solely responsible for the investigation, defence, settlement, and discharge of any such claim.

19. Legal compliance

You represent and warrant that you are not located in a country that is subject to a government embargo, or that has been designated by a government as a "terrorist supporting" country, and that you are not listed on any government list of prohibited or restricted parties. You agree to comply with all applicable third-party terms when using the Application.

20. Third-party beneficiary

You acknowledge and agree that Apple, and Apple's subsidiaries, are third-party beneficiaries of these Terms, and that upon your acceptance of these Terms, Apple will have the right, and will be deemed to have accepted the right, to enforce these Terms against you as a third-party beneficiary.

21. Changes to the Application and to these Terms

We may modify, suspend, or discontinue the Application or any of its features at any time. Features that depend on your device, on Apple Health, or on third-party services may not be available at all times.

We may amend these Terms where reasonably necessary, including to reflect changes to the Application or to applicable law. The effective date at the top of this page will be updated, and material changes will be identified in the Application's App Store release notes. Continued use of the Application after the effective date constitutes acceptance of the amended Terms. If you do not accept them, you should stop using the Application and may cancel any subscription through your Apple Account.

22. Term and termination

These Terms apply for as long as you use the Application. The licence granted in clause 4 terminates automatically if you materially breach these Terms. You may terminate at any time by ceasing use and deleting the Application; deleting the Application does not cancel a subscription, which must be cancelled through your Apple Account. Clauses 11, 13 to 20, and 23 survive termination.

23. Governing law and jurisdiction

These Terms and any non-contractual obligations arising out of or in connection with them are governed by the laws of the Republic of Türkiye. The courts and execution offices of Istanbul, Türkiye shall have jurisdiction over any dispute.

Where you use the Application as a consumer resident outside Türkiye, this clause does not deprive you of the protection of the mandatory consumer law of your country of residence, nor of the right to bring proceedings before the courts of that country where applicable law so provides.

24. General

If any provision of these Terms is held invalid or unenforceable, that provision shall be modified to the minimum extent necessary, or severed, and the remaining provisions shall continue in full force. Our failure to enforce any provision is not a waiver of it. You may not assign these Terms; we may assign them in connection with a transfer of the Application or of our business. These Terms, together with the Apple EULA and our Privacy Policy, constitute the entire agreement between you and us in respect of the Application.
