How can we help?

Check your email inbox (and spam folder) for a receipt from Paddle, then go to your account page's Billing section — your license key is shown there and can be copied any time.

Copy your license key from your account page's Billing section, then paste it into the extension's "Enter license key" field. One license key works on up to 2 devices.

Pro access can take a minute to activate after checkout. Refresh your account page. If it still shows Free after a few minutes, message us below with the email address you paid with.

Go to your account page's Billing section and select "Manage subscription" to open the billing portal, where you can cancel any time. Cancelling stops future renewals; it does not refund the current period.

Memberships are non-refundable except where required by law. See our Refund Policy for details.

Use the "Forgot password?" link on the sign-in page to reset it by email.

Keep Mates stores what you capture locally in your browser. Your account only syncs sign-in, your Pro membership, and your license key — not your saved references.

Check your spam folder first. You can request a new confirmation email from the sign-in page.
