One address for everything: questions, problems and purchases.

Email [email protected]. Write from the address you bought with, and say which Mac and which version of macOS you use. A screenshot of what you see helps.

Your license key

It’s in the email from Polar, the store that handled your payment, and in your Polar customer portal whenever you need it again. Paste it when Just Copy asks, or later in Settings → License.

Installing it again

Deleted Just Copy, or lost the installer? Download it again from justcopy.app/download. It always gets you the latest version, and your license key unlocks it.

Lost your key? Open your Polar customer portal and enter the address you paid with. Polar sends you a code to sign in, and your license key is there. Or email [email protected] from that address and we’ll send it to you.

Moving to a new Mac

On the old Mac, open Settings → License and choose Deactivate this Mac. Then paste the same key on the new one. If the old Mac is gone, write to us and we’ll sort it out.

Paste doesn’t land

Just Copy pastes for you through macOS Accessibility. Open System Settings → Privacy & Security → Accessibility and check that Just Copy is switched on. If it already is, switch it off and on again.

Refunds

Just Copy is free to try for 14 days, so purchases are final. If something went wrong with your purchase, such as a double charge or a key that won’t activate, email [email protected] from the address you bought with and we’ll put it right.

The iPhone app

It’s a free download on the App Store, and your Mac purchase unlocks it: in the Mac app, open Settings → License and click Unlock my iPhone, then tap Check iCloud on the iPhone. Nothing to type; use the same Apple account on both.
