Short version: RFI plugins are protected by commercial copyright. The code is only permitted to be used in combination with a valid software License key, for a single domain, and the License is non-transferable. It is not permitted to copy, or to share in any form, the code or files with any 3rd party. Modifying the code voids all support. Valid licenses include free upgrades and basic support for one year after purchase. Licenses may be optionally extended at a discounted rate.
Long version: Please see the General Terms and Licensing conditions
If you have special requirements, which these terms do not meet, please contact us directly and we’ll see what we can do.
