Your fasts, history, notes, mood entries and settings are saved locally on your device (using Apple's on-device storage). They are included in your normal encrypted device backup if you use iCloud Backup, which is controlled by Apple, not by us. We never receive a copy.
If — and only if — you turn on the weight trend, FastLine asks permission to read your body-mass entries from Apple Health to draw a chart inside the app. This happens entirely on your device. FastLine does not write to Apple Health and never transmits or shares your health data. You can revoke access any time in Settings › Health › FastLine.
Optional Pro purchases are processed by Apple through the App Store using StoreKit. We never see your payment details. Apple's privacy policy governs that transaction.
No account or sign-in. No third-party analytics or advertising SDKs. No tracking across apps or websites. No selling of data — we have no data to sell.
FastLine is not directed at children under 13 and collects no personal data from anyone.
If this policy changes (for example, if we later add optional crash reporting), we will update this page and the "last updated" date.
