Privacy
Last updated: October 8, 2026
The short version
Everything you enter stays on your device. ADF Chronicles has no accounts, and we do not receive or store what you enter.
What is stored, and where
The app saves the following in your browser's storage on the device you are using:
- Your fasting plan, and the fasts you started, ended, recorded or skipped
- Weights you enter, and, if you add them, your height, an age range, a starting weight and a weight goal
- Fasting journal entries: how a fast felt, and any notes you write
- The name you choose for the greeting, if you add one
- Your display choices, such as pounds or kilograms and whether weight and BMI are shown
- When you confirmed the safety information for longer fasts
- A note of each record you remove (which kind of record, and when), kept for syncing between devices if that is ever added
Some of this, such as weight and how you felt during a fast, is health-related. It is not sent to us or to anyone else. It is not shared between your devices, and on an iPhone or iPad the installed app and Safari keep separate copies.
To work without a connection, the app also saves its own pages, code and icons on your device. These contain nothing you entered.
What we do not do
- No account, sign-up or email address is required.
- No advertising and no advertising trackers.
- No analytics or usage tracking.
- No cookies.
- No content is loaded from other companies' servers when you use the app. Fonts and icons are served by ADF Chronicles itself.
Website hosting
The site is hosted by Hostinger. Like any web host, it handles the request your browser makes when a page loads, which includes your IP address and browser type, and may keep standard server logs. Those logs do not contain anything you enter in the app.
Backups
The backup feature creates a file on your device with everything listed above. The file is not uploaded anywhere. Anyone who has the file can read it, so keep it somewhere you trust.
Deleting your data
Use Erase everything in Profile, clear this site's data in your browser settings, or remove the installed app from your device. Because nothing is stored on our side, there is nothing for us to delete.
If you used the earlier version of ADF Chronicles, its own copy of your calendar stays on this device until you clear this site's data in your browser settings. Erase everything does not remove it.
Changes
If ADF Chronicles adds features that store information outside your device, such as accounts, syncing between devices or paid plans, this page will be updated before those features are turned on, and they will be optional. The app will keep working without an account.
