Unless you run a custom ROM, like LineageOS or GrapheneOS, you most probably have some Meta apps installed at system level.

This is Meta Services, as a system app which can only be disabled, on my work Samsung.

Your therapist can’t even have a phone in the room?

I would prefer my psychological issues to not be turned into marketing campaigns. If you still don’t understand what I am talking about, you should probably check the Privacy Policy of Google and Meta.

To save you some time: Google and Meta are monitoring the conversations using the device’s microphone, to better understand what products you may be interested in. You have noticed, that ads are often related to the topics that you discuss face to face.

I had visited an ophthalmologist who used Apple Notes to keep track of his patients. He had no idea about the privacy implications of his choices.

However, my most nerve racking experience was talking to my therapist, while their stock Android was right next to them. Even when I mentioned my privacy concerns, they didn’t bother to get rid of it.
