Privacy policy

Effective: August 30, 2026.

Game data

Sudoku0 stores active games, settings, completion history, streaks, and best times in local browser storage. This data remains on your device and is not linked to an account.

Website and performance analytics

The site is designed for Cloudflare delivery. If Cloudflare Web Analytics is enabled, it is used to understand page traffic and Core Web Vitals. Sudoku0 product events currently use a local browser event interface and do not send data to an analytics service by themselves.

Controls

You can remove locally stored game information by clearing site data for sudoku0.com in your browser. Contact hello@sudoku0.com for privacy questions.

Future services

Advertising, consent management, accounts, cloud synchronization, or additional analytics providers are not currently enabled. This policy will be updated before any such service is introduced.
