Privacy
Short version: we do not collect anything about your prints.
Your print data
Test patterns are generated entirely in your browser from JavaScript functions. Nothing is uploaded to a server, nothing is stored, and no image of your print job leaves your device. Printing uses your browser's own print dialog and your operating system's print spooler.
Analytics
We may use privacy-respecting, aggregated traffic analytics to understand which pages are useful. These record page views and referrers only — not print actions, not device or printer details, and no personally identifying information.
Advertising
If advertising is shown on this site, it is delivered by a third-party network such as Google AdSense, which uses cookies to serve ads based on your prior visits. You can opt out of personalised advertising through your ad network settings or by visiting Google Ads Settings.
Cookies
The site itself sets no cookies. Any cookies are set by third-party services embedded on the page and are governed by those providers' policies.
