Is this post-game analysis extension safe to use on lichess?

I have never analyzed my games but am not a fan of the standard lichess analysis ui, this seems simpler, where you can just go move by move and get a simple line recommendation. As far as I can tell, it can only (thankfully) be used when a game is over, but I want to double check with you guys that it's ok? There is a video of it in action on the chrome page, and screenshots:

Seems fine

But.. lichess does "learn from your mistakes" already?

And engine lines lol

But sure have fun
