How long files stay on our server

Files sent to a server tool are deleted automatically within 30 minutes, whether or not you download the result. We do not read, share or keep them.

Encryption and where the servers are

Every page and every upload travels over an encrypted connection (TLS/HTTPS). The site is served through Cloudflare. The server that processes files for the server tools is hosted by DigitalOcean.

Third parties that load on this site

Built from the live settings: switching analytics or ads on or off changes this table.
