Terms of Service

Last updated: September 8, 2026

These Terms of Service (“Terms”) govern your use of Lift Diary (“the Service”), operated as a website and Android app. By creating an account or using the Service, you agree to these Terms.

1. Eligibility

You must be at least 13 years old to use Lift Diary. By using the Service, you represent that you meet this requirement.

2. Your account

  • You are responsible for keeping your login credentials secure.
  • You are responsible for all activity under your account.
  • Provide accurate information when creating your account.
  • One account per person.

3. Acceptable use

You agree not to:

  • Use the Service for any unlawful purpose.
  • Attempt to access another user’s data or the backend systems.
  • Interfere with or disrupt the Service or its servers.
  • Reverse-engineer, decompile, or otherwise extract source code.
  • Automate access beyond reasonable personal use.

4. Free and Pro subscriptions

  • Free tier: available at no cost, with limits on the number of routines and advanced analytics.
  • Pro tier: a paid subscription billed monthly or yearly through Stripe. Pro unlocks unlimited routines, advanced analytics, and other features.
  • Subscriptions renew automatically until cancelled. You can cancel at any time from Settings; cancellation stops future charges but does not refund the current billing period.
  • Prices may change with reasonable notice; existing subscriptions are not affected until renewal.

5. Your content

You retain ownership of the workout data and routines you enter. You grant Lift Diary a limited license to store and display your data back to you as part of the Service. You can export your data as CSV and delete your account at any time.

6. No fitness or medical advice

Lift Diary is a tracking tool only. It does not provide medical, health, or fitness advice. Calculations such as estimated one-rep max are estimates, not guarantees. Always consult a qualified professional before starting or changing a fitness program. You use the Service at your own risk.

7. Service availability

We strive to keep Lift Diary available but do not guarantee uninterrupted access. We may modify, suspend, or discontinue features at any time without liability.

8. Termination

You may delete your account at any time from Settings, which removes your data. We may suspend or terminate accounts that violate these Terms.

9. Limitation of liability

Lift Diary is provided “as is” without warranties of any kind. To the fullest extent permitted by law, we are not liable for any indirect, incidental, or consequential damages arising from your use of the Service.

10. Changes to these Terms

We may update these Terms from time to time. Continued use of the Service after changes constitutes acceptance of the updated Terms.
