Buy Black Light

Buy directly from the developer. It’s simple, fast, and secure.


Each purchased copy allows activation on one computer, subject to the terms of the EULA. After purchase, you will receive a License Code to unlock the app. You can get your License Code re-sent if necessary.

To install the app on more computers, you need a License Code with the corresponding number of copies. If you make a new purchase using the same name and same email address as an existing License Code, new copies are added to it and you will receive an updated License Code for the combined number of copies.

If your License Code must have a different name than the one on your billing address, you should make the order on the store.


Payment requires a Visa, MasterCard, American Express, Discover, JCB or China UnionPay card. Payment details are handled securely using Stripe. You can also pay using Bitcoin Cash.


If you have trouble placing a purchase, or for any other question, please contact
