Game data
No account is required. Your personal best for each grid size is stored in your browser’s localStorage and is not sent to the server. Clearing site data removes it.
Server logs
Like a typical web server, nginx may keep technical request logs including IP address, path, time, and user agent. These help operate the site and investigate errors.
Third-party services
The site does not load advertising or analytics scripts, use third-party fonts, or create user accounts. Links to research papers lead to external sites with their own policies.
