License – Purchased a license but haven’t received an email receipt with the activation key.

Klok license keys are automatically generated and emailed at the time the purchase was made.

Occasionally email filters will misdirect the email receipt thinking it’s junk mail. 

If you’re not able to locate the email receipt in your inbox or junk mail folders, please send us an email at and note the email address used to make your purchase. We will look up your key and resend it to the email address used to make the purchase.
