Terms of Service

Last updated: April 28, 2026 · Effective date: April 28, 2026

These Terms of Service ("Terms") govern your access to and use of the TallPosture mobile application and related services (the "Service") provided by TallPosture ("we", "us", "TallPosture"). By downloading, installing, or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

Health disclaimer. TallPosture is a wellness and self-improvement app. It is not a medical device, does not provide medical, diagnostic, or therapeutic advice, and is not a substitute for professional consultation. Always consult a qualified healthcare provider before starting any program affecting your sleep, exercise, nutrition, or other health-related behavior. Do not delay seeking medical advice because of something you read or saw in the App. Use the Service at your own discretion and responsibility.

1. Eligibility

You must be at least 13 years old (16 in the European Economic Area) to use the Service. If you are a minor according to the law of your jurisdiction, you may use the Service only with the consent and supervision of a parent or legal guardian who agrees to be bound by these Terms on your behalf. By using the Service you represent that you meet these requirements.

2. Your account

The App creates an anonymous account on your device automatically. You may optionally link an email address, Google account, or Apple ID so you can recover your data on another device. You are responsible for maintaining the confidentiality of any credentials you set and for all activity under your account. Notify us immediately at [email protected] if you suspect unauthorized access.

3. License to use the Service

Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable, revocable license to install and use the App on devices you own or control, solely for personal, non-commercial use. You may not reverse-engineer, decompile, copy, modify, distribute, sell, sublicense, or create derivative works of the App or any part of the Service, except to the extent expressly permitted by applicable law that cannot be waived by contract.

4. Subscriptions, billing, and refunds

4.1 Plans

Some features of the Service require a paid subscription. Available plans, prices, billing periods, free-trial duration, and renewal terms are shown in the App immediately before purchase. Prices may vary by store and country and may include applicable taxes.

4.2 Auto-renewal

Subscriptions purchased through the Apple App Store or Google Play renew automatically at the end of each billing period at the then-current price unless you cancel at least 24 hours before the period ends. Payment is charged to your store account upon confirmation of purchase. You manage and cancel your subscription in the store account settings of your device:

4.3 Free trial

If a free trial is offered, you will not be charged during the trial. If you do not cancel before the trial ends, the subscription will start automatically and your store account will be charged the price disclosed at sign-up.

4.4 Lifetime purchases

"Lifetime" plans grant access for the operational life of the Service on the platform you purchased on; they do not guarantee availability beyond what is technically and legally feasible.

4.5 Refunds

All purchases are made through Apple or Google. Refund requests are handled by those stores under their own policies. We do not process refunds directly. To request a refund, use the store's refund process (Apple: reportaproblem.apple.com; Google: Play refund). Where mandatory consumer law in your jurisdiction grants additional rights, those continue to apply.

5. Acceptable use

You agree not to:

We may suspend or terminate accounts that violate these rules.

6. AI-generated content

The Service includes features that use artificial intelligence (AI Coach, food image analysis, growth predictions). AI output may be inaccurate, incomplete, or out of date and is provided for informational purposes only. You are responsible for evaluating the suitability of any AI output before relying on it. AI is not a substitute for professional advice (medical, nutritional, psychological, legal or otherwise).

7. User content

You retain ownership of any content you submit (e.g., food photos, testimonials). By submitting content you grant us a worldwide, non-exclusive, royalty-free license to host, store, reproduce, modify (e.g., resize), and display that content solely for the purposes of operating and improving the Service for you. We will not use your content for advertising or sell it to third parties.

8. Intellectual property

The Service, including its software, designs, text, graphics, logos, exercise content, and AI prompts, is owned by TallPosture or its licensors and is protected by copyright, trademark, and other intellectual-property laws. Except for the limited license in Section 3, no rights are transferred to you.

9. Third-party services

The Service relies on third parties such as Apple, Google, RevenueCat, OpenAI, and our hosting providers. Your use of those services is also governed by their respective terms. We are not responsible for the acts or omissions of any third party.

10. Termination

You may stop using the Service at any time and delete your account in the App (Profile → Delete Account). We may suspend or terminate your access if you breach these Terms, if required by law, or if continuing to provide the Service becomes commercially unreasonable. Sections that by their nature should survive termination (e.g., Sections 8, 11, 12, 13, 14, 15) will survive.

11. Disclaimer of warranties

To the maximum extent permitted by law, the Service is provided "as is" and "as available" without warranties of any kind, whether express, implied, or statutory, including warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, uninterrupted operation, or that any defects will be corrected. We do not warrant that the Service will produce any specific result, including any change in your height, posture, weight, sleep, or any other health metric.

12. Limitation of liability

To the maximum extent permitted by law, TallPosture and its directors, employees, and agents will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, or goodwill, arising from or related to your use of the Service. In no event will our aggregate liability for all claims relating to the Service exceed the greater of (a) the amount you paid us in the twelve (12) months before the event giving rise to liability, or (b) USD 50. Some jurisdictions do not allow these limitations; in those jurisdictions our liability is limited to the smallest amount permitted by law.

13. Indemnification

You agree to defend, indemnify, and hold harmless TallPosture and its affiliates from and against any claims, damages, liabilities, costs, and expenses (including reasonable attorneys' fees) arising from your breach of these Terms, your misuse of the Service, your content, or your violation of any third-party right.

14. Changes to the Service or Terms

We may modify or discontinue any part of the Service at any time, with or without notice. We may also update these Terms; if we do, we will revise the "Last updated" date and, for material changes, give reasonable notice in the App. Continued use of the Service after a change constitutes acceptance of the updated Terms.

15. Governing law and disputes

These Terms are governed by the laws of the Republic of Türkiye, without regard to its conflict-of-laws provisions. The courts and execution offices of Istanbul, Türkiye, will have exclusive jurisdiction over any dispute arising out of or in connection with these Terms or the Service, except where mandatory consumer-protection law in your country of residence requires otherwise. Nothing in this section limits your rights as a consumer under your local mandatory law.

16. Apple-specific terms

If you obtained the App from the Apple App Store, the following additional terms apply: these Terms are an agreement between you and TallPosture, not Apple. Apple is not responsible for the App or its content. To the extent these Terms grant you a license, that license is limited to use on Apple-branded devices you own or control, in accordance with the Usage Rules in Apple's Media Services Terms. Apple has no obligation to furnish maintenance or support for the App. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price (if any); to the maximum extent permitted by law, Apple has no other warranty obligation. Apple is not responsible for product claims, intellectual-property claims, or compliance with consumer-protection or similar legislation. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

17. Miscellaneous

If any provision of these Terms is held unenforceable, the remaining provisions remain in effect. Our failure to enforce any right is not a waiver. You may not assign these Terms without our prior written consent; we may assign them in connection with a merger, acquisition, or sale of assets. These Terms, together with the Privacy Policy, constitute the entire agreement between you and TallPosture regarding the Service.
