Privacy

The tools have no accounts and store no exercise: each one is generated and forgotten. No student's name, work or answer is ever sent to them.

What is counted

For each request, through the page, the API or the MCP server, and for each MCP connection, one anonymous counter is recorded:

• the channel (page, API or MCP),
• the client software name (the name an MCP client announces, or the first word of the user agent),
• whether the request succeeded, and when it was invalid, the names of the invalid fields (never their values),
• the topic and the trap asked for, and how many exercises,
• the country, as provided by Cloudflare,
• the directory a link came from, when the MCP or API URL names one (?via=).

No IP address, no seed, no identifier that links two requests together. Page visits are counted by Cloudflare Web Analytics, which sets no cookies. The theme you choose is kept in your browser only.

Why

To learn how tutors and AI agents use a small public tool.

Where and how long

The service runs on Cloudflare. The counters are kept in Cloudflare Workers Analytics Engine for at most three months. Nothing is shared with or sold to anyone.
