Math Pages has no accounts, no logins and no server that handles your worksheets. Everything you generate is built in your own browser, so the settings you choose, the problems drawn and the PDF produced are never sent anywhere.
The one thing that does leave your browser is analytics. The site uses Google Analytics to count visits and see which worksheet types are used, which sets cookies and receives your IP address and browser details. It is used to decide what to build next, and nothing else. Google's own description of how it handles that data is at policies.google.com/technologies/partner-sites.
Some things are remembered on your device and never transmitted: the worksheets you recently made, your best quiz scores, and the facts you have missed in a quiz, so practice can be aimed at them. These are stored in your browser's local storage under names beginning “mathpages.”, and clearing your browser's site data for this site removes all of them.
Student names typed into the class-roster box are handled more carefully still: they are held only in the page's memory while you are using it. They are not written to local storage, not put in the URL, and not sent anywhere. Reload the page and they are gone.
This site is intended for parents, teachers and tutors preparing work for children, rather than for children to sign up to — there is nothing to sign up to. If you have a question about any of the above, email mathpageshelp@gmail.com.
No. Worksheets are generated entirely in your browser and the PDF never leaves your device unless you send it somewhere yourself.
Only Google Analytics cookies, used to count visits and see which pages and worksheet types are used. The site sets none of its own.
Clear site data for math-pages.com in your browser settings. That removes the recent-worksheets list, quiz best scores and missed-facts list, all of which are stored locally under keys beginning “mathpages.”.
No. They exist only in the page's memory while it is open — not in local storage, not in the URL, and never sent to a server. Reloading the page clears them.
