Privacy policy: BB Roll

Last updated 24 September 2026

BB Roll is an Android game published by Nessaid Android Studio. You tilt the phone and ball bearings roll across a dial. This policy explains what it does and does not collect.

What the app collects: nothing

The app has no account, no sign-in and no server of its own. It does not ask for your name, your email address or any other personal detail, and there is nowhere for it to send one. Nothing you do in the game is reported anywhere. There is no analytics and no crash reporting.

Motion sensors

The game reads your phone's accelerometer, and its gyroscope if you switch that option on, because the tilt of the phone is how it is played. Those readings are used to work out which way is down and are then thrown away. They are never stored, never sent anywhere and never shared with the ad SDK or anybody else. Neither sensor requires a permission on Android, and neither can tell the app where you are.

What stays on your device

• Your settings: the level, the materials, the friction and sensitivity, the number of balls, the groove spacing, the language and whether the gyroscope is used.
• Boards you save: the shape of a maze you asked to keep, and the name you gave it.

All of it is in the app's own private storage on the phone, and uninstalling the app removes it. Nothing in that list leaves the device.

Sharing

The About screen has a Share button, which offers a link to the app's Play listing to another app you choose. Nothing is shared unless you tap it and pick where it goes, and the app sends nothing by itself.

Advertising

The app shows banner ads, and an occasional full-screen ad between games, from Google AdMob. This is the only part of the app that uses the network, and the only part that involves anybody other than you and your phone.

Google's ad SDK sends four kinds of information to Google in order to select and measure ads: your device's advertising ID, your interactions with the ads themselves, diagnostic information about how the SDK performed, and your IP address, from which an approximate location can be estimated. The app requests no location permission and cannot see where you are; the estimate comes from the IP address every internet connection carries.

That is Google's processing, not ours. We receive no personal data from it and see only aggregate performance figures. This is also what the app declares on its Google Play data safety page, and the two are meant to say the same thing.

Google Privacy Policy · How Google uses information from sites or apps that use its services

You can reset or delete your advertising ID, and opt out of ad personalisation, in your phone's settings under Google, then Ads. The game works the same either way; the ads simply become less relevant.

Consent, for users in the EEA, the UK and Switzerland

If you are in the European Economic Area, the United Kingdom or Switzerland, the app shows Google's consent form before requesting any ad, and your answer is stored on your device by Google's User Messaging Platform. Choosing not to consent to personalised ads does not restrict any part of the game.

Permissions, and why

The app itself requests no permissions. The ones you may see listed come from Google's ad SDK, which declares them in its own manifest:

• Internet and network state: used only to load ads. No other part of the app uses the network.
• Advertising ID: used only by Google AdMob, as described above.
• Wake lock and foreground service: declared by the ad SDK. The game does not run in the background, does not keep your screen awake, and starts no service of its own.
• Basic phone state: declared by the ad SDK. The app does not read it.

None of these prompts you. They are install-time declarations, not permissions you are asked to grant.

Children

The app is not directed to children under 13, and we do not knowingly collect information from them.

Selling data

We do not sell your data. We have none to sell.

Changes

If this policy changes, the date at the top changes with it, and the current version is always at this address.
