Some examples from mine if anyone is curious. I never use the fb sso or any of that shit, nor did I ever explicitly consent to any of these services sharing anything with fb.
- Spotify
- bookings .com
- ebay (haven’t touched my account there in over a decade but they still had data to send this year)
- windy .com
- duolingo
- tinder
- my bank
- opera
- sonos (I can’t think of any time I’ve ever even interacted with this one)
- samsung wallet (another one I never even set up)
- Uber eats
- calorie counter
- mediacom usa and euro (?)
Also, if you remove access via messenger app, it will show a confirm message without closing the screen. Clicking x goes back and it’s not on the list anymore. Whether they are actually leaving it disconnected or just hiding it, who knows.
Some of these services I didn’t use the same email that I used for fb, too, or any email at all.
Most of them were cases where I wasn’t surprised they had data but a bit surprised they shared it.
I think my phone came with a sonos app installed, though not certain about that. I got rid of it if it was, though I can’t say if the most recent update from them was before or after that.
But a few of them I’m not really sure why they are on there. There was another one that I didn’t list that just had the label “IDK”, not sure if that’s a real name or “I don’t know”. I’m assuming they came from effective fingerprinting/tracking.
I might look into an addon that fakes some of the information the browser sends like OS version and resolution. Maybe that will make fingerprinting harder.
