Privacy

Quiet Pixels collects anonymous product-interaction events to help shape the next version. No accounts, no advertising identifiers, no tracking, no personal data.

What we collect

The app sends anonymous product-interaction events to TelemetryDeck, a privacy-first analytics service based in Germany. Events describe what happens in the app — for example, "a daily puzzle was completed" or "the theme changed" — never who did it.

What is not collected:

• No name, email, phone number, or account — Quiet Pixels has no sign-in.
• No IDFA, IDFV, or any device advertising identifier.
• No precise or coarse location.
• No contacts, photos, microphone, or any other system permission.
• No third-party advertising or ad SDKs of any kind.
• No cross-app or cross-site tracking. Events from Quiet Pixels cannot be joined with data from any other app or service.

TelemetryDeck derives a daily-rotating, salted hash from device characteristics to count unique sessions. This hash is not a stable identifier — it changes daily, cannot be reversed to identify the device, and cannot be linked back to you. Under Apple's privacy framework this qualifies as Usage Data → Product Interaction, not linked to user identity, not used for tracking, used solely for App Functionality.

What stays on your device

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

• Your settings — theme, language, audio toggles, mistake mode, daily-reminder time
• Your gameplay statistics — puzzles solved per size, current and best streak, average solve time
• Your in-flight puzzles — so a long Wide puzzle isn't lost if you switch apps

This data lives in the iOS-managed user-defaults store and the app's SwiftData database on this device only. It never leaves the device. Deleting the app deletes all of it.

System APIs the app accesses

Per Apple's required privacy manifest, Quiet Pixels 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 Pixels 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. The anonymous product-interaction events described above contain no personal data and are not used for advertising.

Changes

If a future version of Quiet Pixels ever 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.
