The short version. Airlift runs entirely on your iPhone. There is no Airlift server and no Airlift account. Your data is never sent to the developer. The only network connections are directly between your phone and Google (to sign in and read your health data) and Apple Health on your device. No analytics, no advertising, no tracking.
Google / Fitbit health data. When you connect your Google account, Airlift reads your sleep sessions and the metrics you enable (heart rate, resting heart rate, HRV, blood oxygen, respiratory rate, steps, distance) directly from Google's Health API, processes them on your device, and writes them into Apple Health. They are never transmitted anywhere else.
Apple Health (HealthKit). Airlift writes the above into Apple Health, and reads your existing Apple Health samples only to compare against the Fitbit data so it can avoid duplicates and flag discrepancies. HealthKit data is never used for advertising, never sent off your device by Airlift, never shared with third parties, and never stored in iCloud by Airlift.
Your Google sign-in. The token that keeps you signed in lives in the iOS Keychain, marked device-only (excluded from backups and transfers). It leaves your phone only when your phone sends it to Google for a fresh access token.
If you choose to report a bug from inside the app, Airlift opens a pre-filled GitHub issue in your browser for you to review and submit. It includes the app version and your device model plus any text you type — no health data and no sign-in information. Nothing is sent until you submit it yourself, subject to GitHub's privacy policy. This is entirely optional.
Airlift is not directed at children and does not knowingly collect data from children.
Disconnect your Google account any time in Settings (this removes the sign-in from the Keychain). Remove anything Airlift wrote to Apple Health from within the app or from the Health app directly. Deleting the app removes its local data and the stored sign-in.
If this policy changes, the updated version will be posted here with a new date above.
