Terms of Use

Last updated 20 October 2026

Fatigo is provided as a personal wellness and informational tool.

Estimates, not orders

Alertness scores are estimates. They are not a diagnosis, not a clinical assessment, and not a determination of whether you should work, drive, or sleep. You are responsible for those decisions.

Not a medical device

Fatigo is not intended to diagnose, treat, cure, or prevent any condition. It is not a clinically validated fatigue measurement device.

Safety-critical choices

By using the app you agree that you will not rely on it as the sole input for safety-critical choices. Fatigo does not know when you are unsafe and does not prevent accidents.

Plus

Subscription terms (if you purchase Fatigo Plus) are presented by Apple at checkout, including auto-renewal, price, and how to cancel in Settings → Apple ID → Subscriptions.

On-device data

Core scoring and logs live on your iPhone. See the Privacy Policy for Health, location, export, and delete.

Changes

We may update these terms. The date at the top is the current version.
