Delete your data
FastWithin has no accounts, so there is no account to delete. Everything the app stores is on your phone, and you can erase it yourself in a few taps.
Delete everything on your phone
- Open FastWithin and tap Settings.It is the last tab at the bottom.
- Find Your data and tap Delete all my data.It is in the Your data section, near the bottom of Settings.
- Confirm.This erases every fast, meal, note and setting FastWithin stored on that phone. It cannot be undone.
Plus is separate. Plus purchases stay with your Google account and can be restored later. Deleting your data does not cancel a subscription. To cancel, open Settings, tap Manage or cancel, and cancel in Google Play.
Or uninstall the app
Uninstalling FastWithin removes the app and its data from your phone. If your phone has Android backup turned on, your phone's backup may still hold a copy of the app's data. That backup belongs to you and your Google account, and you can manage or delete it in your phone's backup settings. We do not hold it.
What we hold on our side
| Account | None. We have no account for you, so there is nothing to delete. |
|---|---|
| Fasting history, meals, notes, bedtime, settings | Stored only on your phone. They are never sent to us. |
| AI photo logs | None. A photo you send with Photo I ate is not stored by FastWithin, so there is no log of your photos to delete. Google's Gemini API handles the photo under Google's terms. |
| AI helper counters | The helper keeps a random install ID and a count of that day's AI requests, only to enforce daily limits. They are not linked to you as a person, and they hold no photos, food names or history. |
| This website | No cookies, no analytics, no accounts. |
