Your puzzle. Your choices.

What happens in a game.

Sudoku entries, notes, and word selections are processed in the current browser tab. They are not sent to a server or saved after a refresh. There is no account system.

Privacy preferences.

If you make a choice in the privacy dialog, the site stores that choice in your browser's local storage under et-consent-v1. This lets it remember your preference. Browser settings can remove that stored choice.

Analytics and advertisements.

With your permission, Google Analytics measures page visits, links selected, article reading depth and time, and general game activity. The Google tag loads only after you accept optional analytics. Your browser then shares page and device information and network request information with Google; analytics cookies may remember a browser across visits. We do not send names, email addresses, puzzle entries, or search text. Google signals, advertising storage, ad user data, and ad personalization remain disabled. Reject or withdraw optional analytics at any time through Privacy choices. Read the Google privacy policy and how Google uses information from sites that use its services.

Google AdSense is not active. No ad script or advertising cookie is loaded. A future advertising integration requires an updated notice, the required consent setup, and any applicable account approval before use.

Newsletter.

Newsletter signup is closed. This site has no active email subscription form and does not collect email addresses.

External sites.

Amazon and social profile links take you to services with their own privacy notices. No social widgets, video embeds, or third-party fonts load automatically on this site.

Hosting and requests.

Hosting and network providers can process basic request information, such as IP addresses, to deliver pages and maintain security. This site does not send puzzle entries or email addresses with those requests. Optional analytics and newsletter collection are described separately above.

Questions.

Use the official profile links on the contact page for general project questions. Do not share sensitive information in a public comment. If you need to discuss private information, request a private contact route first rather than posting it publicly.
