Please enter the license from your purchase receipt to receive your activation key.
Your license key is provided in the receipt Gumroad emailed you at the time of purchase. You can also find it on the download page for in Gumroad.
No. Only this page reaches out to the internet. Once your unlock key is in the app it is verified entirely on your own machine.
Yes. One purchase grants you unlimited access for all of your devices. The same unlock key works on all of them, so keep a copy somewhere you can find it.
Come back here and enter your license key again. You'll get the same unlock key, as many times as you need.
You can, but beware. The unlock key is signed with your email address. So sharing the key also means sharing your email address. You will also need access to the embedded email when requesting support.
The key is signed with a private key that exists only on our server. Aventurine ships with the matching public key. That lets the app confirm a key really came from us without ever talking to us over the internet. It also means a key cannot be forged or generated, even though Aventurine's source code is published.
