Do I get to keep my programme for ever?

I've worked out with FB for over a decade but never got Plus for financial reasons. Recently I bought the FBReboot programme to help me ease back into fitness after illness. It came with a 15 day pass for Plus. It is saying that it is about to run out, and I was wondering do I lose my programme too? Or do I have access to the programme forever? I haven't completed it yet. Thanks
