Method 1: Direct In-App Copy

If Pro is already active in Tessamark on your iPhone, iPad or Mac, you can skip receipts altogether:

1 Open Tessamark on your iPhone, iPad, or Mac.

2 Go to Settings → Licence & Pro.

3 Tap Copy Licence Key.

4 On Linux, open Tessamark → Settings → Enter Licence Key and paste it.

The app checks your App Store purchase itself and gives you your key, with no website involved.
