Biwo is an intermittent fasting tracker that helps you manage fasting windows with simple timers and proven methods (16:8, 18:6, 20:4, OMAD). The app is designed to work offline; all data is stored locally on your device.
3. Health disclaimer
Biwo is a tracking tool, not medical advice. Intermittent fasting may not be suitable for everyone. Consult a healthcare professional before starting any fasting program, especially if you have pre-existing health conditions, are pregnant, nursing, or under 18.
4. License and acceptable use
We grant you a personal, non-exclusive, non-transferable license to use Biwo for your own non-commercial use, subject to these Terms.
You agree not to:
- Reverse engineer, decompile, or attempt to extract the source code except where permitted by law
- Use the app in a way that interferes with its normal operation
- Circumvent any usage limits or access controls
5. Intellectual property
Biwo, including its design, branding, mascot character (Bowi), and software, is owned by the developer and protected by intellectual property laws.
6. Disclaimers
Biwo is provided “as is” and “as available”. We do our best to keep the app reliable, but we do not guarantee:
- That the app will be uninterrupted or error-free
- That fasting timers will always be perfectly accurate in all conditions
If you notice a bug, please contact us at contact [at] reachus.app
7. Limitation of liability
To the maximum extent permitted by law, the developer will not be liable for indirect, incidental, special, consequential, or punitive damages arising out of or related to your use of Biwo. This includes any health-related outcomes from fasting practices.
8. Termination
You may stop using Biwo at any time by deleting the app.
We may suspend or terminate access if you materially violate these Terms, where permitted by law.
9. Governing law
These Terms are governed by the laws of France, without regard to conflict-of-law principles. Courts located in France will have jurisdiction where applicable.
