Effective March 18, 2026
Fast Days is designed with your privacy in mind. We collect minimal, anonymous usage data to improve the app. No personal information is ever collected or sold.
Fast Days stores your preferences locally on your device using Apple's standard storage. This includes:
This data never leaves your device and is not transmitted to any server.
We use Mixpanel to collect anonymous usage data that helps us understand which features are most helpful. This includes:
This data is not linked to your identity. We do not collect your name, email address, or any other personal information through analytics.
You can opt out of analytics at any time in the app's Settings under "Analytics."
If you enable daily fasting reminders, notifications are generated entirely on your device. No notification data is sent to any server. We use Apple's local notification system only.
The only third-party service we use is Mixpanel for anonymous analytics. We do not use advertising networks, data brokers, or any other third-party tracking services.
For Mixpanel's own privacy practices, see Mixpanel's Privacy Policy.
All app data is stored locally on your device. Uninstalling Fast Days removes all stored data. There is no account to delete because we don't create accounts.
Fast Days does not knowingly collect any personal information from children under 13.
If we update this policy, we will post the revised version here with a new effective date. Material changes will be communicated through the app.
