A license is a small signed file. The app checks it offline when it starts. No internet is needed to run a registered app.
Each license covers up to 20 different machines a year. Reinstalling on the same machine does not use a new one.
Press it in any 00rg app, sign in, and every app you own is registered on that machine at once.
When someone you invite registers an app, you get twice what they paid as credit toward 00rg subscriptions.
Accounts and registration open soon.
The apps are free to use right now. They show a short message each time they start until you register. When registration opens, this page is where you sign in and pay.
