FAQ

Which permissions does it need?

Accessibility, so it knows when a window closes. Screen Recording is optional: with it, animations start from the window’s real last frame; without it, from a gray stand-in. Nothing is requested until you confirm the privacy notice.

How does the license work across Macs?

Each seat binds to one Mac at a time. You can move a seat to a new Mac once every 30 days, up to 3 times a year. Reinstalling macOS on the same Mac doesn’t count.

Will future effects be free?

No promises either way. Everything available when you buy is yours to keep; new effects added later may come free or be sold separately.

Does it need to stay online?

Only once, to start the 7-day trial after you agree to the privacy notice. After you buy, the app refreshes its offline token about once a week and keeps working for 30 days offline. If the trial ends without a purchase, it stops going online.

Can I get a refund?

Yes—full refund within 14 days of purchase, no questions asked. Email support@curtain-call.dev.

Why isn’t it on the Mac App Store?

Detecting window closes across apps requires non-sandboxed Accessibility APIs that the App Store doesn’t allow. Every release is Developer ID signed and notarized by Apple.
