This notice explains what data we collect, how we use it, and which third-parties help us deliver the app.
- Information We Access
- Location (Required): used exclusively for Auto-detect Altitude. Data stays on-device and is never transmitted.
- Barometer & Motion Sensors: optional “Boost accuracy with barometer” reads ambient pressure locally and discards results immediately.
- Notifications (Required): needed to alert you when timers finish, even in the background.
- On-device Storage
- Preferences, altitude units, premium status, and altitude references are stored in iOS secure storage (UserDefaults/Keychain). No analytics or behavioral data is collected.
- Third-party Services
- Google Mobile Ads SDK serves ads to non-premium users and may receive device identifiers required for ad delivery.
- Apple StoreKit processes any in-app purchases; payment data never touches our servers.
- User Controls
- Disable location, motion, or notifications anytime via iOS Settings > Egg Timer. Turning off location disables Auto-detect Altitude.
- Premium purchases remove ads across all devices tied to the same Apple ID.
