Privacy

Last updated November 2026.

MathMath runs entirely in your web browser. Your worksheets and calculations are never sent to us: opening and saving use files on your own computer, and we keep no account or record of you.

What stays in your browser

If you turn off the welcome screen, MathMath remembers that choice in your browser's local storage. It is never sent anywhere. Clearing your browser's site data removes it.

Images you load from the web

If you load an image by its web address, your browser fetches it straight from that site, which sees your request as it would any other.

Hosting

The site is served by Cloudflare, which processes visitors' IP addresses and request details to deliver pages and protect the service. See Cloudflare's privacy policy.

Visitor statistics

We use Cloudflare Web Analytics to count visits: which pages are viewed, how fast they load, and roughly which country visitors come from. It sets no cookies and doesn't track you across sites or build a profile of you. See Cloudflare Web Analytics.

Advertising

The site may show ads from Google AdSense, to help pay for it. When it does:

• Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
• Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.
• You may opt out of personalized advertising by visiting Google's Ads Settings, or opt out of some third-party vendors' use of cookies for personalized advertising at aboutads.info.
• Visitors in the European Economic Area, the United Kingdom and Switzerland are asked for consent before any advertising cookies are used, and can change their choice at any time.

See how Google uses information from sites that use its services. Ads are only ever shown beside the worksheet, never on it, and never print.

Donations

If you choose to support MathMath, the "Buy me a coffee" link takes you to Buy Me a Coffee, which handles the payment under its own privacy policy. We receive your name and message only if you give them there.
