Fatigo computes your alertness on this device.

Apple Health

Read-only. Fatigo may read sleep, heart rate, heart-rate variability, breathing rate, and activity to estimate current alertness. Data stays on your device unless you export it.

Logs you enter

Sleep, naps, caffeine, shifts, and drives are stored locally on your iPhone.

Sentences you type

Parsed on this iPhone to log last night, a nap, coffee, a shift, or a trip, or to ask a what-if. Not sent to a server.

Location

Used only when you add a Drive destination, to estimate time and pause places. Not used to track you in the background.

Account

No account is required for the core loop. Plus is billed by Apple against your Apple ID.

What we do not do

• No selling of health data.
• No tracking by default.
• HealthKit data is used for app functionality, not advertising.

Export and delete

In Settings you can export or delete logs you entered. Deleting logs does not remove Apple Health data or a Plus subscription billed by Apple.
