Privacy Policy
Scores stay on your device, we count pageviews without cookies, ads come from Google.
Game scores
Personal bests and game state (like an unfinished sudoku) are stored in your browser's local storage on your own device. They are never sent to our server. Clearing site data in your browser erases them.
Analytics
We run our own lightweight pageview counter. When a page loads, your browser sends us the page path and referring site. To estimate unique visitors we derive a temporary identifier from your IP address and browser signature; it is a one-way hash that rotates daily and cannot identify you. No analytics cookies, no profiles, no data sharing.
Advertising
Ads are served by Google AdSense. Google and its partners may use cookies or device identifiers to personalize ads based on your visits to this and other sites. Opt out at Google Ads Settings, and see how Google uses data from partner sites.
Contact form
Messages sent through the contact form reach us as email (name, address, message) and are used only to reply.
Server logs
Our host keeps standard rotating web logs (IP, URL, timestamp) for security and debugging.
Children
The games are family-friendly, but the site does not knowingly collect personal information from children under 13; it collects almost nothing from anyone.
