Privacy Policy

Overview

Astro Sudoku is designed to be played without an account and without collecting personal data. The app does not sell, share, track, or transmit personal information.

Data Stored On Device

Astro Sudoku may save puzzle progress, best times, mission stats, streaks, badges, unlock progress, selected language, selected theme, sound settings, music volume, haptics settings, and optional reminder preferences. This information stays on your device.

Web Game Storage

The browser version uses local browser storage to remember active puzzles, settings, records, streaks, and badges. This information stays in your browser and can be removed by clearing site data. It is not sent to Astro Sudoku servers.

Leaderboard Data

If you use web leaderboards, Astro Sudoku stores a randomly generated player identifier, your chosen pilot name, verified completion times, mission, mistakes, hints, and ranking date. To prevent automated abuse, the service temporarily stores a one-way, daily-changing network fingerprint; it does not store the raw network address. No account, email address, or password is required. You can keep playing offline without submitting leaderboard data.

Notifications

If you enable Daily Mission Reminders, Astro Sudoku may schedule local notifications on your device. These reminders are optional and can be turned off in the app settings or in iOS Settings.

Analytics And Tracking

Astro Sudoku does not use third-party analytics, advertising trackers, or cross-app tracking.
