An ordinary screenshot can be edited and does not show where the page came from. A page captured with TrueScreen is certified with its address, date and time, with a qualified electronic seal and a qualified timestamp.

If the way the page was captured may be challenged, use the Forensic Browser. If the content matters and you need to be quick, the Browser Extension does the job; from your phone, use the app.
Can I certify a page that requires a Login, such as a social profile?
Yes. The Browser Extension uses the Login already open in your browser; in the Forensic Browser and in the app you sign in inside the session.
How long can a session in the app last?
Up to 10 minutes on Android and 30 minutes on iPhone and iPad: the recording stops automatically at the limit.

No, it works in Chrome and Edge. The Forensic Browser runs on macOS and Windows.
