SUDOKAIJU Privacy Policy

Overview

SUDOKAIJU is a fully offline, single-player Sudoku game published by polysign.lu. We designed the game to work without collecting personal data.

Data we collect

SUDOKAIJU does not collect personal data or usage data. The game does not collect, transmit, store on remote servers, sell, rent, or share information about you.

The game has no user accounts, analytics, advertising, tracking, in-app purchases, third-party sign-in, social features, or user-generated content.

How the game works with data

Puzzle generation, Sudoku entries, scores, and sound controls operate locally on your device. SUDOKAIJU does not send this game activity to polysign.lu or to third-party services.

Third parties

SUDOKAIJU does not share data with third parties because it does not collect data. Apple may independently process information related to downloading, purchasing, and using apps under Apple's own privacy policy. That processing is controlled by Apple, not by SUDOKAIJU or polysign.lu.

Retention, deletion, and privacy choices

Because SUDOKAIJU does not collect personal data, polysign.lu has no personal data from the game to retain, access, correct, export, or delete. There is no data-collection consent to withdraw. You can remove locally managed app data by deleting the app from your device.

Children's privacy

SUDOKAIJU does not knowingly collect personal data from children or from any other users.

Changes to this policy

If SUDOKAIJU's data practices change, this policy will be updated before the change takes effect. The effective date and last-updated date above will also be revised.
