Data-Light Fasting App

In short

Data-Light Fasting App means fasting tracking should be useful without asking for unnecessary data or adding friction before the user can start a timer.

How local-first works

Stored on your iPhone

Sessions, streaks, settings, and widget state live in local app storage — not on our servers.

No account to create

There's no sign-up and no profile. You open the app and start fasting.

Delete anytime

One tap in Settings wipes all local app data from your device and its widget storage.

What you gain

✓Your fasting history never leaves your phone.

✓No ads and no data sold — ever.

✓Instant start with nothing to set up.

The honest tradeoff

•Data lives on one device, so keep iCloud backup on.

•No cross-device cloud sync (by design).

•Deleting the app removes its local data.

Private fasting, done right

Fast Goblin gives you streaks, stats, reminders, and widgets without the surveillance. Read the full privacy policy for the details.
