I guess you can deactivate them.

Then probably you can use an aggregator like Franz.

Never tested, but I guess you can throw the Meta app away then.

Edit: It seems Franz it thought for desktop, Snowball should do the job.

I don’t use much of Fb (or Ig, BlueSky), but I always use them on browser even on the phone. I’ve any app installed for social medias except Lemmy.

In my case they shouldn’t be able to track me, or?

This assume we have a Facebook app on the phone in oder to work, right?
