Click checkbox to reveal content (Also record it to BP profile)

Hi all,

I run a membership site where people pay to view tutorial videos. I have had loads of requests to make the videos downloadable. I am happy to do this but where I am usually happy to give a refund to people who decide it is not for them I don’t want to give a refund to those who have already downloaded all my videos.

My hypothetical solution is to have the content hidden from view until they click a box say “I understand that after downloading these videos no refund will be given for any reason.” Then I need this to be recorded on their profile (backend only) so I can check this before issuing refunds.

I am not really worried about this being a fail safe solution and I don’t mind how simple the mechanism is (i.e. I am not expecting this to secure the content against people who don’t agree and manage to find the download url)

I hope someone can help point me in the right direction.

Thanks in advance.
