I made this app last year but it's so clunky to access your data that I didn't release it. This year there have been more requests for this type of app from YouTube and so I decided to throw it up for others to use. You can see an example of it here: https://youtube-rewind-production.up.railway.app/results/606...

Also, I should note that while I am storing your watch history/subscriptions for generating the rewind, the actual data does not contain any of your information except the videos you've watched and your subscriptions. I cannot use this information to identify you.
