Privacy Policy

Last updated · May 2026

The short version

No data leaves your phone, except anonymous usage counts (with no identifiers attached) so we know which features people actually use. There is no account to create.

What stays on your phone

Your alarms, profiles, challenge settings, sounds, and any barcode or QR codes you save are stored in a local database on your phone. Nothing is synced to a server. Delete the app and the data is gone with it.

Anonymous analytics

The app uses TelemetryDeck to count anonymous events like "the alarm fired" or "a challenge was completed." A short hash is generated on your phone so we can tell sessions apart, but the hash can't be tied back to you, your phone, or your Apple ID. No IP address is stored. No advertising identifiers, no behavioral tracking, no data sold to anyone.

For App Store privacy labels, this is the "Product Interaction" data category, not linked to your identity, not used for tracking.

Device permissions

The app asks for these system permissions, used only as described:

• Notifications & alarms. To schedule and ring the alarm at the time you set.
• Camera. Only when you set up or scan a barcode or QR code challenge. Camera frames are read on the phone and not stored or sent anywhere.
• Motion & fitness. Only when you use the walk challenge, to count your steps. Read on the phone, not stored or sent.

Payments

If you buy the premium unlock, the payment is handled by Apple through the App Store under Apple's privacy policy. Apple shares with us a transaction identifier so the app can confirm the purchase on your phone. We don't see your name, email, or payment details.

Diagnostics

If you opt in to share crash reports through TestFlight or iOS Settings, Apple may send anonymous crash logs to App Store Connect. You can turn this off in iOS Settings. We don't run our own crash reporter.

Children

The app isn't directed to children and doesn't ask anyone for personal information.

Changes

If this policy changes, this page and the date above will be updated.
