Is anyone developing a way to see everything you've "Followed On ROKU"

I am not sure if I understand correctly but if I somewhat understand it correctly. There are usually 2 ways in dealing with this.
1) Server side where a user has an account, is logged in and retrieves that data from the database.
2) Use cookies to mark something as followed, watched, add to playlist, likes etc.. in which all these would work with option one as well.

I have seen more and more places use cookies since users want interaction but not to always sign up.

To explain further: Users can follow movies, shows (or seasons or episodes thereof) on ROKU.
I know ALL of these are stored in ROKU's database But only the ones whose status has changed show up in "My List".
I know this because I've searched for Movies & shows that are not in my list, only to find I've already followed them. - but they may not be currently available on ROKU OR none of the major channels has changed their status recently (Available to buy, rent, for free etc.)
I'd like to be able to pull up EVERYTHING I've followed.
