    Sign in with your purchase email

    Enter the email you used when you bought it. A 6-digit code lands in your inbox: there is no password to remember.

    That’s it

    Your subscription is recognised and Pro switches on. It then follows you across up to 5 devices, and keeps working for 14 days with no internet connection.

Bought from the App Store or Google Play?

Sign in with the same address first, then tap “Restore purchases” in the settings. Check that you are on the Apple or Google account that paid: that is by far the most common reason a purchase cannot be found.

Looking for an old license code?

Alphanumeric codes are no longer used as of September 2026: the app no longer has a field to enter one. If you bought before that change, simply sign in with your purchase email. If your access does not come back, write to us and we will attach it by hand.

Stuck? Write to [email protected], mentioning the email address used for the purchase.
