Common questions.

Capturing and scrubbing run entirely on your Mac, but ScrubShot makes one network call to validate your trial or license with my server. If a firewall, VPN, or app-level blocker like Little Snitch denies that call, Settings will show "Couldn't reach server" next to License, and capture is paused while ScrubShot can't confirm your trial or license.

To fix it, allow ScrubShot to make outgoing connections in whatever is blocking it. Little Snitch shows you the destination when it prompts, so you can click Allow. Then do any one of the following:

• Open Settings and click Try again next to License.
• Open Settings and paste your license key, then click Activate. The activation call doubles as a retry.

ScrubShot also re-checks on its own whenever you bring it to the front, so once you've unblocked it you usually don't need to do anything.

A few things gate the capture shortcut. Run through these in order:

1. Are Screen Recording and Accessibility granted? Settings shows "Granted" next to each when they are. Screen Recording lets ScrubShot capture the screen; Accessibility lets the shortcut work system-wide.
2. Has ScrubShot reached the server? If Settings reads "Couldn't reach server" next to License, see the question above. Capture is paused while ScrubShot can't confirm your trial or license.
3. Is your trial still active? If the 7-day trial has ended and no license is active, pressing the shortcut shows the "Trial ended" screen instead of capturing.
4. Is another tool intercepting the keys? If something like Karabiner is remapping Fn or Space, it'll catch the press before ScrubShot sees it.

Not yet, but it's on the list. For now the shortcut is Fn + Space. I'll add a shortcut picker in Settings in a future build, as a free update.

Every capture is saved to ~/Pictures/ScrubShot, and you can copy one to the clipboard at any time. Your screenshots stay on your Mac. ScrubShot never uploads them.

The only network call ScrubShot makes is to my license server, to validate your trial or license (it carries a hashed machine identifier and your license status, nothing more), plus an anonymous check for the latest version. Your screenshots, and everything you scrub out of them, are never uploaded, never logged, and never sent anywhere. The full detail is on the privacy page.

In System Settings → Privacy & Security → Accessibility, ScrubShot should appear with a toggle. If it doesn't, add it manually: open a Finder window, go to Applications, and drag the ScrubShot icon straight onto the Accessibility list. Or click the + button at the bottom of the list and choose ScrubShot from the file picker.

Once it's in the list, flip the toggle on. That's the permission that lets the Fn + Space shortcut work no matter which app you're in. Without it, the shortcut won't fire.

Open ScrubShot's Settings and click Open next to Diagnostic log to see the local log file. It records app events with timestamps to help me track a problem down; the contents of your screenshots are never written to it.

Then get in touch through the contact page with a short note about what went wrong, and the log if it's relevant. I read these myself.

Send it through the contact page. If it's the kind of thing other people are likely to ask too, I'll add it here.
