  Core Promise: Take Your Sudoku does not collect, store, or upload any of your personal data. All game data stays on your device. The only network feature is optional Game Center integration. We do not collect, store, or upload any of your personal data.

1. Information Collection

We do not collect any information. Specifically:

Game Data: Your game progress, scores, and statistics are stored locally on your device only using Apple's standard UserDefaults and Game Center APIs.
Personal Information: We do not require account registration and do not collect names, emails, phone numbers, or any other personal information.
Analytics: We do not use any analytics tools, crash reporting SDKs, or advertising tracking SDKs.

If you sign in to Game Center, Apple may collect data according to their own privacy policy. We do not have access to your Game Center account information beyond what Apple's APIs provide (public leaderboard scores and achievements).

3. Data Storage

All game data (saved games, statistics, preferences) is stored exclusively on your device. No data is transmitted to external servers. You can delete all game data at any time through the Settings page within the app.
