I am not the full expert on the subject, but I assume the profiling is to a lesser extent. For one you don’t browse within a Google account.

I also like the slimmed down UI and subscription management of invidious compared to yt.

And don’t forget no ads and sponsorblock. Although some add ons like vinegar for safari get you pretty close to uninterrupted viewing.

All said, probably not the best in regards to pure privacy.

How quickly those this flood your storage?

Currently I ran invidious in docker. The solution is … just okay, performance isn’t great. But at least you only stream whatever you pick for watching.

I only follow around 15 channels. For simplicity 10 video are added daily to my subscription feed.

Are there privacy concerns with this solution. This together with ad blocking were my main drivers for invidious.
