Privacy

Quiet Circuits 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 Circuits has no sign-in.
• No IDFA, IDFV, or any device advertising identifier.
• No precise or coarse location.
• No contacts, photos, camera, or microphone.
• No third-party advertising or ad SDKs of any kind.
• No cross-app or cross-site tracking. Events from Quiet Circuits cannot be joined with data from any other app or service.

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

What stays on your device

A few things are stored locally so the app remembers what you were doing. They never leave your device and are not sent to us:

• Your settings — theme, audio toggles, difficulty, and the optional daily-reminder time.
• Your progress — the current daily board, puzzles solved, and your completion streak.

You can erase all of it at any time with Settings → Reset all data. Removing the app also deletes everything stored locally.

Device sensors

The “Circuit” board theme tilts its lighting as you move the phone, using the accelerometer and gyroscope. These readings are used only to light the board on screen in real time — they are never recorded, stored, or transmitted. Turn the effect off with system Reduce Motion.

Notifications

If — and only if — you turn on the daily reminder, the app schedules a local notification on your device at the time you choose. It is created and delivered entirely on-device; no notification service or server is involved.

Feedback you send

If you use Settings → Send feedback, your message (and an email address only if you choose to type one) is sent so we can read and reply. Nothing is collected unless you actively send it.

Children

Quiet Circuits is suitable for all ages, collects no personal data, and shows no advertising.

Changes

If this policy changes, the updated version will be posted here.
