Privacy
Short version: what you make and paste stays in your browser.
What you enter
Colours, gradients, selectors, stylesheets and every other value you type, paste or open in a tool are processed by JavaScript in your browser tab. They are not uploaded, logged or stored on a server. A CSS file you open in the px to rem converter is read locally and never leaves your device. Reloading or closing the tab discards everything.
Analytics
The site uses Cloudflare Web Analytics, which counts page views without cookies or cross-site tracking. It never receives what you type, paste or drop into the tools. There are no other analytics, ads or trackers.
Cookies and storage
The site sets no cookies. If you choose a light or dark theme, that choice is saved in your browser's local storage under one key and never leaves your device.
Network access
The site's Content-Security-Policy allows connections only to this site and to Cloudflare's analytics endpoint, so the pages cannot send your data anywhere else. Links to other websites, such as the sister sites and recommended services in the footer, only take you there when you choose to follow them; those sites have their own privacy terms.
