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.

Garbage! If you want to just remove all your subscriptions i suppose it's worth it. But that's not what i want, eh

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!
