What you get

Start free, and it is the real thing

Basic has no subscription, and your first file is free, sealed the same way as on Plus. After that you buy files when you need them; nothing is taken out of them.

The stamp bar

It appears on the first capture you make. There is no template to choose and no watermark to position.

The file

Your captures stay together, with a checklist that says what is still missing and a report you can send straight away.

Sealed by someone else

The seal comes from a supervised service on the European trust list, not from us. Whoever receives the file checks it against that service’s signature.

Before you install

What your phone needs

Short list, and none of it is unusual. The one thing worth checking is the age of the device, because the signing key has to live in secure hardware.

iPhone	iOS 18 or newer. The signing key is created in the Secure Enclave, which every supported iPhone has.
Android	Android 12 or newer, with a hardware-backed keystore. That is standard on phones from roughly 2020 onwards, and where a device has StrongBox the key goes in there.
Storage	Your captures stay on the device, so allow for the space: a file of twelve photos at 12 megapixels is around 38 MB. A ten-minute video takes about 600 MB.
Connection	Not needed while you shoot. Signing happens on the phone. A connection is needed once, to seal the file and record it in the registry.
Account	None. To join a company on Business your phone links with a linking code, again without an account; only people who use the dashboard sign in.
The recipient	Nothing at all. A browser is enough to check a file, on any device.

The same on both

iPhone or Android: the same file

The file, the report and the verification page are the same. There are two differences: who vouches for the key inside your phone, Apple or Google, and where the counter comes from: on iPhone from App Attest, on Android kept by the app.

Check a file

Been sent a file by someone else? Drag it onto the page to see when it was sealed, with which device and under which stated name, and what is inside it. There are four samples of stamped PDFs ready too, one of them a PDF with a forged timestamp date.
