When you purchase our software directly from us (as opposed to in the App Store), you receive an email with a license file download link. Once downloaded, double-clicking the attached license file licenses the associated program. Once licensed, selecting the License menu in our programs will display a nicely-personalized license file.

Note: As explained in the license file email you receive, the download link will expire in a few days, so please download your license right away.

Both Peter and I prefer to these license files over serial numbers for many reasons (they seem more personal, they don’t require copy-and-paste and app switching, etc.), but there is one downside: many users aren’t sure where to keep a copy of the file, to ease migrating to a new machine, or just for safekeeping. It turns out it’s actually very easy to back up these files…
