Privacy policy

Udfyld collects no data. The app has no account, no ads, no analytics and makes no network connections.

The PDFs you open are read and saved on your iPhone: in the folder you opened them from, or in the Udfyld folder in the Files app. Nothing is sent to Peter Theill or anyone else.

Your signature and initials are stored in the Keychain on your iPhone and never leave the device.

When you share a file, you use the iPhone's own share sheet and decide who receives it.

This website is hosted by Cloudflare, which processes technical request data (such as IP addresses) to serve and protect it. The website uses no cookies and no analytics. See Cloudflare's privacy policy.
