Bell Circuit — Privacy Policy

Effective date: November 6, 2026

Bell Circuit is a musical puzzle game published by Proliferaite LLC. It is played alone, on one device, and it works with no network connection at all. There are no accounts, no sign-in, no profiles and no game servers. We never see what you play or how you solve it.

What stays on your device

Your progress — which levels you have solved, your stars, your best results, and whether you have seen the opening tutorial — is written to your device's own app storage and nowhere else. It is not backed up to us and it is not tied to any identity. Uninstalling the app deletes all of it.

What the app does not ask for

Bell Circuit asks you for no device permissions. It does not use the microphone, the camera, location, contacts, files, or your photo library, and it cannot, because it never asks for them. (Network access, which needs no prompt, is used only for the diagnostics, ads and purchase checks described below; the game itself plays offline.)

That includes the microphone in particular, which is worth saying plainly for a game made of sound: every note you hear is generated by the app on your device as it plays. The app ships with no recordings and it never listens.

What is collected automatically (diagnostics)

To find and fix crashes, the app uses Google Firebase Crashlytics and Firebase Analytics. When the app runs, Google's SDKs may collect:

• Crash logs and stack traces
• Diagnostics: device model, operating system version, app version
• Basic usage events, such as opening the app or finishing a level
• Anonymized identifiers (such as a Firebase installation ID) used to count installs and de-duplicate crash reports

This information is used solely to keep the app working and is processed by Google LLC on our behalf. It is encrypted in transit, retained by Google for a limited period, and then deleted. We do not sell it.

Advertising

Bell Circuit shows ads in exactly two places, and never over a puzzle you are playing:

• A full-screen ad between levels, when you move on from a level you have solved, and only on every third solve.
• An optional video you may choose to watch to reveal the final hint on a level. The earlier hints are always free, and declining always leaves the level solvable with what is already on screen.

There are no banner ads anywhere in the game, and ads are muted — the app silences them before any ad is requested, so a video cannot start playing sound over the music.

Ads are served by Google AdMob, which may process device information and, with your consent where required, an advertising identifier in order to serve and measure ads. In the European Economic Area, the UK and Switzerland you will be asked for consent before any ad is requested, and you can decline.

On iOS, Bell Circuit does not show the App Tracking Transparency prompt and does not request the advertising identifier (IDFA). Ads on iOS are therefore non-personalized, and nothing about you is linked across apps or websites owned by other companies.

You can reset or delete your advertising identifier at any time in your device settings. For details on Google's practices see How Google uses information from sites or apps that use its services.

Purchases

Bell Circuit offers one optional in-app purchase, Remove Ads: a single payment, not a subscription, that removes every ad from the game permanently and makes every hint free. The purchase is handled entirely by Google Play or Apple's App Store; we never see your name, card or other payment details, only the store's confirmation that the purchase exists. A record that you own it is kept by the store (so you can restore it on a new device) and on your device. The price, refunds and your cancellation rights are set out in the Bell Circuit Terms of Service.

Children

Bell Circuit is suitable for a general audience. We do not knowingly collect personal information from anyone, including children. There is no chat, no user-generated content, no social feature and no way for players to contact one another. The only data that reaches third parties is the anonymous diagnostics, the ad-serving data and the store purchase record described above.

Data deletion

Everything you create in the app lives on your device: uninstalling the app deletes it. Diagnostic data held by Google expires automatically. For any request or question, contact us at the address below.

Changes

We will post any changes to this policy at this URL and update the effective date above.
