Fastii — Privacy Policy

Last updated: September 12, 2026

The short version

Fastii was built so that your fasting times, notes, and streaks never leave your phone. There are no accounts, no analytics trackers, and no advertising SDKs. We cannot see, sell, or share your log, because we never receive it.

What is stored, and where

Fasts, notes, water glasses, how a fast felt, optional weight entries, protocol, appearance, language, and notification settings are stored locally with the operating system's app storage. Deleting the app deletes this data. You can also erase everything from Settings → Delete all data.

Notifications

If you allow notifications, Fastii can remind you when an eating window opens or closes and when a timed fast reaches its goal. Reminders are scheduled on this device. You can turn them off in Settings.

Purchases

Subscriptions are processed by Apple. We use RevenueCat to validate purchases. RevenueCat receives an anonymous app-generated identifier and purchase receipts, never your fasting log.

Not medical advice

Fastii is an informational timer and log. It is not a medical device and does not diagnose, treat, prevent, or cure any condition. It does not prescribe a diet. Talk to a clinician before you change how you eat.
