Privacy
Short, because the site does almost nothing.
What happens to the text you type
Nothing leaves your device. The conversion runs in your browser using JavaScript that was downloaded with the page. There is no server-side component, no API and no logging of input, because the site is a set of static files on a CDN.
What is stored on your device
Two things, in your browser's local storage: the styles you marked as favourites, and the last text you typed, so the page looks the same when you come back. Both stay on your device. Clearing site data in your browser removes them.
Analytics
Aggregate page views are measured without cookies and without collecting anything that identifies you personally. No cross-site tracking, no advertising profile, no session replay.
Advertising
If display advertising is added, this page will be updated first to name the provider and describe what it collects, and consent will be requested before any advertising script loads. At the time of writing, no advertising is served.
Contact
For anything relating to this policy, including a request to know or delete data, use the contact address published on the site. Since no personal data is collected, in practice there is rarely anything to delete beyond your own browser storage, which you control directly.
