Your files stay on your device. 30-30 processes data in your browser. We do not upload your data to a cloud server, and we do not share it with anyone.
Imported files and your workspace stay in this browser until you clear site data for 30-30.app. Recent files and bookmarked views store a handle in this browser so you can reopen a file you already picked; the file itself stays on your disk.
Loading the site (and map backgrounds, if you open the map) uses ordinary web requests to our host and to map providers. Those requests do not include your files.
If you choose to sign in, we use your email only to send a sign-in code. That is separate from your files, which still never leave your device.
