Privacy
citefold is built so that your documents cannot reach us. This page says what the site, the checker, and the checkout do with data, in full.
The checker is one HTML file. It reads the document you drop on it in your browser's own memory and sends it nowhere: the build refuses a page that could make a network request, and the page carries a Content Security Policy under which your browser blocks every connection, on this site and in a saved copy alike. It keeps one thing in your browser's local storage, on your machine: the licence key you pasted, so you do not have to paste it again. Clear the browser's site data and it is gone.
These pages make no requests either: no analytics, no fonts, no images, no cookies. The one thing they keep in your browser is the theme you chose. The host that serves the files keeps ordinary web server logs, as any host does; the pages report nothing to anyone.
Buying a licence happens at Lemon Squeezy, the merchant of record, under its own privacy policy and terms; it handles payment details, receipts, and tax. We receive the order: the name and email address given at checkout, used to issue and send the licence key and for nothing else.
