Your free add-ons are still free, but the license to it expires in 6 months. What happens when the license expires?

Even if the license needs to be renewed if you want to download the free product again after 6 months, there will be no charge for it.

You can use each licensed and installed product on your XenForo forum without any limit of time. You only need to extend your license if you want to download a new version of a product after 6 months.

This is only to keep your license data current with our records.
