Privacy
Draft. The parts in {{double braces}} are still to be filled in by the site's owner. This page describes what the site's code does; it is not legal advice.
Last updated: November 3, 2026
Mathzetta ("we", "us") runs MathZetta at mathzetta.com. The site is built so that we learn as little about you as possible: there are no accounts, and everything you type is worked out in your browser. Questions: [email protected].
Your maths stays in your browser
Everything on this site — the home page's try-it box, the playground, the operations reference, the postfix quiz, the API examples and the test runner — runs the MathZetta library in your browser. What you type is not sent to us or to anyone else. The CDN page composes addresses from a file we serve; it sends nothing.
What is stored on your device
The postfix quiz puts the expression you are working on in the page's address (after the #) so a link can share it; browsers don't send that part to the server. Nothing else is stored: there are no cookies and no analytics or advertising on mathzetta.com.
Who else is involved
| Service | Why | What they receive |
|---|---|---|
| {{HOSTING_PROVIDER}} | serves the site | the usual web-server logs: your address, the pages you ask for and when, your browser's name; kept {{LOG_RETENTION, e.g. 14 days}} to run the site securely |
| Google Fonts (fonts.googleapis.com, fonts.gstatic.com) | the two typefaces the pages use | a request for the font files, with your address and browser name |
| jsDelivr (cdn.jsdelivr.net) | KaTeX, on the playground and the test runner only, to draw LaTeX | a request for those files, with your address and browser name |
The libraries this site publishes (MathZetta, Inline Math, tabview, qblur) are served to other sites by jsDelivr and unpkg from npm; what those sites do with your data is up to them.
Your rights
We hold no personal data about you beyond the server logs above, so there is nothing to show, correct or delete on request; the logs expire on their own. Depending on where you live you may have further rights under laws such as the GDPR or the CCPA; write to [email protected] and we will answer within {{30}} days.
Children
The site collects nothing from anyone, children included.
Changes
We'll update this page when the site changes and note the date above.
