Privacy Policy

Last updated: 30 June 2026.

Coordinate data

Coordinates you enter into the converter are processed entirely in your browser via the proj4js JavaScript library. They are never transmitted to our servers, logged, stored, sold or shared with any third party.

Browser storage

EPSG Transform stores two small items in your browser's localStorage to improve your experience: your most-recently used CRSs (so you don't have to re-search them) and your theme preference (light, dark or system). These never leave your device.

Cookies and analytics

We use Vercel Web Analytics for cookieless, aggregate traffic stats such as page views. It sets no cookies and collects no personal information.

Server logs

Our hosting provider may keep short-term server logs of HTTP requests (URL, IP address, user agent) for security and abuse prevention. These logs are not used to track or profile individual users.
