How activation works

Buy on the checkout page. Stripe is our merchant of record: it takes the payment, charges any sales tax and sends your receipt. We never see your card.
We email your license key to the address you bought with, a minute or two after the payment goes through. Keep that email: we store only a fingerprint of the key and cannot show it again.
Open the extension's options page and paste the key under Pro. One key works on up to 3 of your browsers; "Deactivate this device" frees one.

Your tab titles, addresses and other browsing data stay on your device. Activating Pro sends license-validation data to our license-check service: the key, the extension's name and two random identifiers for the installation and the browser, so the service can confirm the key and count your devices. See the extension privacy policy.
