2. The App

2.1 The App is a tool for recording and managing your own eating schedule (fasting and eating windows). No account is required.
2.2 The timing of the timer, widget display and notifications depends on Android's battery-saving features, your device settings and manufacturer-specific features, and may be delayed (by up to about 10 minutes on Android 12 and later). We do not guarantee the accuracy of times.

3. Health notice

3.1 The App is not a medical device or a medical service. It does not recommend any specific diet or health method, and does not provide medical advice, diagnosis, or treatment.
3.2 The App does not promise weight loss or any other health benefit.
3.3 Whether to fast, and for how long, is your own decision and responsibility. Stop fasting immediately if you feel unwell.
3.4 If you are pregnant or breastfeeding, under 18, have a medical condition or take medication, or have a history of eating disorders, consult a doctor before use.

4. Paid features

4.1 The App is free to use. Some features ("Paid Features") can be unlocked with a one-time in-app purchase. There are no subscriptions and no ads.
4.2 What is free, what the Paid Features include, and the price are shown on the in-app purchase screen and on the App's Google Play listing.
4.3 Payment is processed by Google Play. We do not receive your credit card number or other payment details.
4.4 A purchase is tied to the Google account used to buy it, and can be restored after reinstalling or on a new device using the same Google account. Paid Features are not shared through Google Play Family Library.
4.5 Refunds follow Google Play's refund policy. Within 48 hours of purchase you can request a refund through Google Play. After 48 hours, please contact us (Section 12); except where the law requires otherwise, we decide refunds case by case.
4.6 We may change the content of the Paid Features to improve them, fix bugs, or respond to changes in Android or Google Play.

5. Prohibited conduct

6.2 What you record in the App belongs to you. We do not receive it.

7. No warranty

We do not warrant that the App fits your particular purpose, that its records, statistics and display are always accurate, that it is free of bugs, or that it works on every device.

8. Limitation of liability

8.1 If you suffer damage due to our breach of contract or tort, except in cases of our intent or gross negligence, we are liable only for direct and ordinary damage actually incurred, and for damage relating to Paid Features, up to the amount you paid for them.
8.2 Your records are stored only on your device. If they are lost because the App is uninstalled or the device is reset or broken, we cannot restore them. Use CSV export to keep a copy if needed. Fasting records older than 800 days are deleted automatically.
