Off by default. If enabled, Vercel measures visits and loading speed on our public information pages to help improve them. Teaching pages, document identifiers and URL queries are excluded. Vercel receives connection information, such as your IP address and browser details.

This browser: Off. You can turn it off here at any time, free of charge. Your choice stays on this browser; Do Not Track and Global Privacy Control keep it off.

Teaching and browser storage

Sign-in cookies and local teaching drafts support the service. Turning off measurement does not remove your work. Signing out clears local classroom data; Account provides export, history clearing and deletion.

Commons image searches and images pass through our server, which sends the search terms to Wikimedia without forwarding your browser cookies, IP address or user agent. Search for teaching subjects, never pupil names or personal information. Image credits link to external websites only when you choose to open them.

Canvas fonts and icons are served by Tumble. Your browser uses Tumble and its hosting and storage providers during teaching. Google receives an authentication request only when you choose Google sign-in.
