These terms are an agreement between you and Tetsu ("we", "us") covering your use of the Tetsu mobile application. By creating an account or using the app you accept them. If you don't agree, don't use the app.
You must be at least 13 years old to use Tetsu. If you're under the age of majority where you live, you may only use the app with a parent or guardian's consent.
You're responsible for the accuracy of your account information and for keeping your credentials secure. You may delete your account at any time in Settings → Account, which permanently removes your data.
Tetsu is not a medical service. Workout plans, nutrition suggestions, calorie estimates, and all AI-generated guidance are general fitness information, not medical advice, diagnosis, or treatment. Consult a qualified professional before starting a new exercise or diet program, especially if you have a medical condition, are pregnant, or are recovering from injury. Exercise carries inherent risk; you use the app and perform any activity at your own risk and within your own limits. Stop and seek medical help if you feel pain, dizziness, or discomfort.
Some features generate content with artificial intelligence based on your inputs. AI output can be inaccurate or incomplete. It's provided as a starting point for your own judgment, and we don't guarantee its accuracy, completeness, or suitability for your circumstances.
You own the data and content you put into Tetsu (workouts, logs, photos, notes). You grant us the limited license needed to store and process it solely to operate the app for you. Progress photos stay on your device and are not uploaded to our servers.
Don't misuse the service: no unauthorized access, scraping, reverse engineering (except where the law permits it), reselling, abusing AI features (including attempts to generate harmful content), or interfering with other users' use of the service. We may suspend or terminate accounts that violate these terms.
We work to keep the service available and improving, but it's provided "as is" and "as available", without warranties of any kind to the extent the law allows. We may add, change, or remove features. If we discontinue the service, the in-app data export remains available beforehand where reasonably practicable.
To the maximum extent permitted by law, we are not liable for indirect, incidental, special, consequential, or punitive damages, or for personal injury arising from your exercise or dietary decisions. Our total liability for any claim is limited to the greater of the amount you paid us in the twelve months before the claim or US $50. Nothing in these terms excludes liability that cannot be excluded by law.
You can stop using the app or delete your account at any time. We may suspend or terminate access for breach of these terms, with notice where practicable.
If we make material changes we'll update the date above and notify you in the app before the changes take effect. Continuing to use the app after that means you accept the updated terms.
These terms are governed by the laws of India, without regard to conflict-of-law rules. Where local consumer-protection law grants you mandatory rights, those rights are unaffected.
