3AM Privacy Policy

Effective 28 August 2026 · applies to the 3AM iOS app (rest.3am.app) and this website (3am.rest)

The short version: your sleep data never leaves your phone. 3AM has no accounts, no server for your data, no ads, no data sales, and no third-party trackers in the app. The only things the app ever sends anywhere are anonymous feature-usage counts (which you can switch off) and plain version-safety checks.

What stays on your device — everything personal

Your shift schedule, sleep windows, check-ins, Recovery Scores, patterns, weekly reports, Together people, and anything read from Apple Health (sleep only, read-only, and only if you connect it). All computation happens on the phone. There is no account and no cloud copy held by us.

What leaves the device

Anonymous usage counts — event names like "check-in logged" go to TelemetryDeck, a privacy-first analytics service, with no identifiers, no health data, and no way to link them to you. You can turn this off in the app: You → Consent Center → "Usage counts".
Version safety checks — the app fetches a small configuration file from 3am.rest and asks the App Store for the latest version number, so we can warn you if your installed version has a known problem. Nothing about you is attached to these requests.
Purchases — subscriptions are processed entirely by Apple. We never see your payment details.

What never exists

No ads. No sale of data. No third-party trackers or ad-tech SDKs in the app. No push notification tokens (all alarms and reminders are scheduled locally on your phone).

Apple Health

If you connect Apple Health, 3AM reads your sleep samples — nothing else — to score your recovery. This data is processed on-device and is never uploaded, shared, or used for anything except showing you your own numbers. 3AM never writes to Apple Health.

Your controls

Inside the app, You → Consent Center lets you: switch off usage counts, export everything the app knows as a JSON file, and delete everything in one tap. Deleting is immediate and unrecoverable — there is no server copy to linger.

This website

3am.rest is a static site hosted on Firebase Hosting (Google), which keeps standard server logs to operate the service. The site uses Firebase Analytics to count visits — with advertising signals and ad personalization disabled, and we honor your browser's Do Not Track and Global Privacy Control settings by not loading analytics at all. The sleep calculator runs entirely in your browser; nothing you type into it is sent anywhere. No ads, no data sales, here either.

Age

3AM is intended for people 13 and older.
