I purchased the wrong premium

Licenses for each browser are separate products with different prices and functionalities.

We cannot interchange licenses. If you made a mistake when purchasing a license and you wish to change your premium, you have one month to obtain an unconditional refund and buy the premium of your choice.

All you have to do is send a request for a refund to licenses@downloadhelper.net with details like email address used for purchase or license key.

To make sure you buy the right premium, the links for each browser are available here: https://github.com/aclap-dev/video-downloadhelper/wiki#purchase-premium
