buying the full app gives you a license key, tied to the email you bought with. paste it into settings and you're done.
one key activates the full app on up to three Macs at a time. to free a slot for another, sign a Mac out while it's online, in the app's settings.
the app checks in with our license service now and then, and it keeps working without a connection: a 14-day grace period keeps the full app running offline before it falls back to the free meter.
and one promise in writing: if Maltby Ventures ever winds peddra down, the last release removes the license check, so the app you paid for keeps working without us.
questions about your license or your Macs: email contact@peddra.com and a human answers.
