Terms of Service

Effective May 25, 2026

These Terms of Service ("Terms") govern your access to and use of Tallevate (the "Service"), operated by Tallevate ("we", "us", "our"). By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

1. Eligibility

You must be at least 13 years old to use the Service. If you are between 13 and 18, you confirm you have permission from a parent or guardian. Parents may use the Service to track a child's growth on their own account.

2. Your account

You are responsible for safeguarding access to your account, including any sign-in codes sent to your email. You are responsible for activity that occurs under your account. Notify us promptly if you suspect unauthorized access.

3. The Service: what it does and does not do

Tallevate provides AI-assisted height predictions, an AI Coach, and tools to log growth, sleep, nutrition, and exercise. Predictions are produced by statistical models (Khamis-Roche / mid-parental height) applied to data you provide.

Tallevate is not a medical device, not medical advice, and not a substitute for a healthcare professional. Outputs from the Service — including predicted adult height, coaching tips, and AI-generated images — are estimates for informational and educational use. Always consult a qualified clinician for questions about growth, nutrition, exercise, or any medical condition.

4. Acceptable use

You agree not to:

  • Use the Service to harm, harass, impersonate, or defame anyone.
  • Upload content depicting minors other than yourself or your own child.
  • Reverse-engineer, scrape, or attempt to extract source data from the Service.
  • Probe, scan, or test for vulnerabilities without prior written consent.
  • Use automated systems to bypass our rate limits or cost controls.
  • Use the Service in violation of any law in your jurisdiction.

5. AI-generated content

The Service uses third-party AI models to produce predictions, coaching text, and images. AI outputs may be inaccurate, incomplete, or unexpected. You are responsible for evaluating outputs before relying on them. You retain rights to the inputs you provide; outputs are provided to you on an "as is" basis subject to these Terms and applicable AI provider terms.

6. Subscriptions and billing (when active)

Paid plans, when offered, are sold through the Apple App Store or Google Play and processed by the respective platform. Subscriptions renew automatically until you cancel. Cancel any time via the App Store / Play Store subscription settings. Refunds are subject to the platform's policy. We reserve the right to modify pricing with notice.

7. Free trials and beta features

We may offer free trials or beta features. Free trial terms are disclosed at sign-up. Beta features are provided without warranty and may be modified or removed at any time.

8. Intellectual property

The Service, including its software, design, content (excluding your inputs and outputs), trademarks, and branding, is owned by Tallevate and protected by intellectual-property laws. We grant you a limited, non-exclusive, non-transferable license to use the Service for personal, non-commercial purposes.

9. Your content

You retain ownership of the inputs you submit (selfies, measurements, logs, messages to the Coach). You grant us a limited license to process those inputs solely to operate and improve the Service. You can delete your content at any time by deleting the relevant records or your account.

10. Termination

You may stop using the Service at any time. You may delete your account in the mobile app under Profile → Settings → Delete Account, or by emailing us. We may suspend or terminate accounts that violate these Terms, abuse the Service, or present a security risk.

11. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT PREDICTIONS WILL MATCH ACTUAL OUTCOMES.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, TALLEVATE AND ITS AFFILIATES WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUES, OR DATA, ARISING OUT OF OR RELATING TO YOUR USE OF THE SERVICE. OUR TOTAL LIABILITY FOR ANY CLAIM RELATED TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM OR (B) USD 50.

13. Indemnification

You agree to indemnify and hold harmless Tallevate from any claims, damages, or expenses arising out of your violation of these Terms or your misuse of the Service.

14. Changes to these Terms

We may update these Terms from time to time. Material changes will be communicated in the app or by email. Continued use after changes take effect constitutes acceptance.

15. Governing law and disputes

These Terms are governed by the laws applicable at our principal place of business, without regard to conflict-of-law principles. Disputes will be resolved in courts of competent jurisdiction unless local consumer-protection law requires otherwise.
