Download Calamo Pro
Thank you for buying Calamo Pro. Your licence key is in the email from Polar. Download the app below, then enter the key in Help → Licence.
Everything works for 14 days from the first start, with no account and no card. Then the app asks for a licence key: $49 once, buy it here.

What the app sends
Nothing from your files. Only when you enter a licence key, and every 30 days after that when you are online, the app asks the licence server (Polar) whether the key holds. Privacy · Documentation
