WaterFast Terms of Use

Last updated: July 2026

Apple EULA. This application is subject to the standard Apple Licensed Application End User License Agreement (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Not medical advice. WaterFast helps you time fasts and shows educational information about fasting zones. It is not a medical device and does not provide medical advice, diagnosis or treatment. Consult a qualified healthcare professional before starting any fasting protocol, especially if you have a medical condition, are pregnant or take medication.

1. Your responsibility

You decide when and how to fast. WaterFast only measures time and displays reference information; how you use it is your responsibility.

2. Subscriptions (WaterFast PRO)

PRO is offered as an auto-renewing yearly subscription at $9.99/year (with a 7-day free trial) and as a one-time lifetime purchase at $24.99. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings. Payment is charged to your Apple ID. Güije Studios does not process payments directly.

3. No warranty

The app is provided "as is", without warranties of any kind to the extent permitted by law.

4. Changes

We may update these terms; continued use of WaterFast means acceptance of the updated terms.
