I switched to FreeTube not long ago. It has a local account that is independent from Google or any online activity. Meaning it will save your watch history and favorites and other settings without having a Google account. You can easily backup your local profile.

And you can import your subs. If you want, you can also use a different API backend from Individous, instead the Local API from FreeTube itself. Individious API is even more private then the Local API, as it does not connect to Google directly. But it gets broken more often, so you have to switch the Individious instance from time to time. And and don't forget the integration of SponsorBlock. And I have a setting to hide watched videos, which unclutters my view of over 120 subscribed channels.

All good. But not all, there are couple of problems we encounter from time to time. The biggest issue is, that Google is attacking these applications and services, because Google does not like them. That means, sometimes FreeTube gets broken and you can't watch a video or something is just not right. Sometimes it helps to switch to Individous if there is a working instance. Just today got a new FreeTube hotfix release, because we encountered issues.

And you can't like or comment, as it is anonymous without Google account. For that, I have to login in my Firefox browser with my account and comment this way. It's a bit annoying, if that is an important point for you.
