What Data We Collect
- Account info: Name and email address provided during registration.
- Usage data: Your progress in tests and scores.
- Technical data: IP address and cookies for session management.
Note: We do not store credit card details. Payments are processed via Stripe.
AI assistant connector (MCP): when you connect an AI assistant to your account, we log every tool call it makes and link it to your account. The log contains the tool name, the tool arguments (such as task or topic ids and filters), the outcome, the duration, the client name and version, the OAuth client id, the user agent and the time of the call. We do not log the content of your chats or your prompts. We use this log to operate the service, protect it from abuse, apply rate limits and provide support. Log entries are deleted after 90 days.
Feedback through the AI assistant: if you ask the assistant to send feedback, we store the text of the message, its kind (bug, idea or other), the AI client name and version and your language, linked to your account. It is kept for 365 days. Bug reports are reviewed together with that day's tool-call log.
