A short note on your data.

Betninja does not collect, transmit, or share any personal information.

Betninja is an offline word-connect crossword game: you trace letters on a wheel to fill a grid and pick up the extra words hidden in the same letters. The pages that follow describe, in plain language, what the app does and does not do with the things you type into it.

I · Collection

Information we collect

None. The game asks for no email address, no sign-in, no contacts and no payment details. The only thing you ever type is a diver name for your own profile, and that name stays on your phone.

II · Storage

What lives on your device

For the app to work, the following is kept in the operating system's local storage, on your phone, and nowhere else:

the diver name and avatar mark you pick on the profile screen;
which grids you have cleared, the stars and score earned on each, and how many bonus words you have found;
your in-game Prism balance, daily-streak counter and the date of your last daily reward;
the workshop upgrades you have bought and the bonus words shelved in your codex;
your option toggles (reduced motion, high contrast, auto-submit, chapter intros) and flags noting that you have already seen the intro and each chapter card.

None of it is uploaded. Uninstalling the app removes every byte.

III · Permissions

What the app asks for

The game requests no runtime permissions: no camera, microphone, location, contacts, photos, storage or notifications. The Android manifest declares the normal android.permission.INTERNET permission, which comes with the standard Flutter project template. It is not a dangerous permission, you are never prompted for it, and the app never uses it, because it contains no networking code.

IV · Network

What goes over the wire

Betninja is fully offline. Every puzzle, word list, image and font is bundled inside the app. It does not contact any server, API or content delivery network, and it plays the same in airplane mode.

V · Third parties

Who else is involved

None are integrated. There is no analytics SDK, crash reporter, advertising or attribution library, and no social or cloud SDK. Besides the Flutter framework, the app uses only open-source UI and storage libraries (flutter_bloc, hive, confetti, intl), and none of them collect or transmit data.

VI · Children

Younger readers

Because the game collects and transmits nothing, it is suitable for players of any age and complies with COPPA and GDPR-K by design. We do not gather personal information from children, or from anyone else.

VII · Your rights

What you can do

All data is local, so it is already under your control. The profile, medals and codex screens show everything the game stores. To erase it permanently, uninstall the app: Android removes its private storage along with it. There is no server copy to request, export or delete.

VIII · Revisions

Changes to this policy

If anything in this policy changes, the date at the top of the page will be revised, and material changes will appear in the app's release notes.
