License key disappeared from my account or didn't appear there after the purchase
Don't panic.
Please contact the support team by sending a message to support@adguard.com They will help find and restore the license key. You will need to provide some kind of proof of purchase, though (check your email): the license key itself, purchase receipt, etc.
Glad we’re able to help!
