鍛錬Terms of use
By using Tanren (the website and the app at /app/), you agree to these terms. Last updated: October 30, 2026.
1. The service
Tanren is a free habit, weight and training tracker that runs in your browser. No account is required. We may change, add or remove features at any time.
2. Health
Tanren is not a medical device and does not give medical advice. Calorie targets, goal dates, est. 1RM and other numbers are estimates. Exercise at your own risk; stop if you feel pain and consult a doctor if you have a medical condition, are pregnant or breastfeeding, or are under treatment.
3. Your data
Your logs are yours. See the Privacy policy for what is stored and what your crew can see. Keep your transfer code private — anyone with it can move your data to their device within its validity period.
4. Crews
Only invite people you know. Don't use names or habit names that are abusive, illegal or infringe others' rights. We may remove content or access that breaks these terms.
5. Drops
Drops are free in-app credits you earn by opening the app. They have no cash value, can't be transferred or exchanged, and expire as shown in the app.
6. Prohibited use
Don't attack, overload, reverse-engineer for abuse, or interfere with the service, and don't use it for anything unlawful.
7. No warranty; limitation of liability
The service is provided "as is". To the extent permitted by law, we are not liable for any loss of data or damages arising from your use of the service.
8. Changes
We may update these terms and will post the new version on this page.
