Privacy Policy

Last updated: 8 August 2026

Brain Test is a single-player puzzle game. This policy explains what the app does today, and — because apps evolve — what may change as it grows, so you always know what to expect.

What the app does today

Current status: advertising and analytics — no accounts

Brain Test does not collect your name, email address, or any other information that identifies you personally. There are no accounts, no sign-up, and no login, and we operate no servers of our own.

The app does show advertising. From version 1.1.0, a full-screen ad from Google AdMob appears between levels — never during a puzzle, and not at all until you have solved more than ten of them. To serve and measure those ads, the Google Mobile Ads SDK collects and sends to Google:

Google processes this data as an independent controller under its own privacy policy.

The app also uses GameAnalytics to understand how the game is played, so we can tell which puzzles are too hard and which parts of the game confuse people. It records, against a random identifier generated on your device (not your name or account):

This is behavioural and technical data about how the game is used. It is not sold, and it is not used to identify you personally.

Apart from ad requests and these analytics events, the game makes no network requests: the puzzles themselves work fully offline.

Data stored on your device

The app saves the following only on your device, using local storage, so your game works the way you left it:

This saved file itself is never uploaded anywhere. (Separately, the analytics events described above do report gameplay facts such as which level you completed and how long it took — but your saved progress file is not transmitted.) Uninstalling the app, or clearing the app's storage, permanently removes it.

As the app grows

Brain Test is actively developed, and future versions may introduce features that were not part of the app on the date above — for example:

Accounts and cloud save

If we ever add optional sign-in (for example, to sync progress across devices), it would be opt-in, and this policy would be updated first to describe exactly what account data is collected and how it's used.

Whenever any of the above is added, we will update this policy before the feature ships, update the "Data safety" section of the app's Play Store listing to reflect it accurately, and note it in the app's release notes. We will not silently start collecting data that isn't disclosed here.

Third-party services

Brain Test uses two third-party SDKs, each processing data under its own terms as well as ours:

Permissions

The app requests no sensitive device permissions (no location, contacts, camera, microphone, or storage-access permissions). It does declare the Android advertising ID permission (com.google.android.gms.permission.AD_ID), which the ads SDK requires. If a future feature needs a new permission, Android will prompt you for it at that time, and this policy will explain why it's needed.

Your choices

You can:

Children's privacy

The app is suitable for all ages, but it is not directed at children, and we do not knowingly collect personal information from children. Ad content is restricted to Google's "General audiences" content rating, and the app is not flagged as child-directed. Where a user is known to be under the applicable age of consent, ads are served without personalization.

Data retention & deletion

Local data (progress and settings) is retained on your device until you clear the app's storage or uninstall it — at which point it is permanently deleted.

The advertising and analytics data described above is held by Google and GameAnalytics on their own systems, under their own retention schedules, which are set out in their privacy policies linked below. Because the app has no accounts, we hold no profile to delete on request; what you can do instead is reset or delete your device's advertising ID (see Your choices), which breaks the link to any future data, and decline consent where a consent form is shown to you, which stops analytics events being sent at all.

International users

Brain Test can be played anywhere, and your saved progress file stays on your device. The advertising and analytics data described above is sent to Google and to GameAnalytics respectively, and may be processed on servers outside your own country — including in the United States — under those companies' own terms and transfer safeguards.

Changes to this policy

If this policy changes, the updated version will be posted at this same URL with a new "Last updated" date above. Meaningful changes (such as adding advertising or analytics) will also be reflected in the app's Play Store "Data safety" section and release notes.
