We collect minimal data to generate worksheets and improve the service.
This site is hosted on Render. We save anonymous worksheet parameters (e.g. "Addition") to our analytics database. We do not store IP addresses in this database.
Note: Standard server logs (maintained by our hosting provider for security and operations) may temporarily contain IP addresses.
We use Google Analytics 4 to understand website traffic. This service sets cookies and transmits data to Google. It is blocked by default and only activates if you explicitly consent via our Cookie Banner.
