A license key from this site unlocks this website edition; a purchase in the Mac App Store edition unlocks that edition. Keep one edition per Mac: both claim the same extensions, so two copies would show them twice in System Settings. More on turning them on.

Questions

How does it update?

Showglass checks showglass.vpolabs.com for a new version at most once a day and asks before it installs one. Every update is signed by VPO Labs and notarized by Apple.

What does the app send?

Your files never leave your Mac, and the Quick Look extensions have no network access. To activate and check a license, the app sends the key and this Mac’s name to Dodo Payments. The update check asks this site for the newest version. See the privacy policy.

Where do I enter my key?

Open Showglass, choose Settings › General, then Enter License Key… under Showglass Pro. The Open in Showglass button on the page after checkout fills it in for you.
