Privacy

Quiet Letters does not collect, transmit, or share any personal data. Everything stays on your device.

What we collect

Nothing. The app has no servers, no accounts, no analytics, no advertising, and no third-party SDKs that talk to the network. There is no telemetry of any kind.

What stays on your device

Quiet Letters stores a few things locally so the app remembers what you were doing:

• Your settings — theme, language, audio toggles, hard-mode default, daily-reminder time
• Your gameplay statistics — games played, win rate, current and best streak, guess distribution
• Your daily-puzzle progress — so a daily isn't lost if you switch apps mid-game

This data is written to the iOS-managed user-defaults store and SwiftData database on your device. It never leaves the device. Deleting the app deletes all of it.

System APIs the app accesses

Per Apple's required privacy manifest, Quiet Letters declares one system API category: NSPrivacyAccessedAPICategoryUserDefaults (reason CA92.1 — accessing user defaults that belong to the app itself). No other reason categories apply.

Notifications

If you enable the optional daily reminder, the app schedules one local notification through iOS. The notification is generated entirely on-device — no server is involved. You can turn it off at any time in Settings → Notifications, or via iOS Settings.

Children

Quiet Letters is rated 4+ and contains no objectionable content, no chat, no user-generated content, no in-app purchases, and no advertising. It is safe for children under 13.

Changes

If a future version of Quiet Letters ever adds something that changes the privacy posture (for example, opt-in advertising in v1.1 — currently a deferred consideration), this page will be updated and the change called out in the in-app release notes before the new version ships.
