It says "manage" your subscriptions and likes etc., it literally DELETES ALL when you press Start Cleaning, and NOWHERE does it say it's gonna do that..I lost half of my sub's, literally if you wanna make a "mass unsubscribe" extension go for it, but 1) call it THAT and 2) ASK TWICE before starting that mayhem and since there's no "unsubscription log" in google activity, also please LOG the channel links somewhere as you do that!!
This just made this little sunday task a much bigger problem than it was, so thank you very much, i guess.

Oh this is the BEST!! Tried a few others but this was all in one go and gone!!! Thanks mate!!

One of the few extensions that can actually remove all the videos from your "Watch Later" playlist. 5/5 no BS here.

Wow, this was bad--it started unsubscribing me from *all* my subscriptions without warning. Removed all my letter "A" subscriptions within a few seconds. No way to get them back or even see what they were. Stay away from this extension!
