That's so funny that they come up with this page these days.

"We receive Jane's off-Facebook activity and we save it with her Facebook account. The activity is saved as "visited the Clothes and Shoes website" and "made a purchase"."

I downloaded my data before, and never have I seen what exactly the listed companies sent to FB.

I have a list of just a few companies (mainly by using a different email address for FB only) but still, I have no idea what these companies sent to FB about me.

Edit: I found the data now - it's now available for export.

Clearly I need to step it up. I was (unsurprisingly) surprised at what I've observed they've managed to correlate. I run standard pi-hole, resist fingerprinting, and normally go through a VPN (mainly because I'm on public wifi half the time when travelling). I haven't logged into facebook in about four years, just did it for the first time today to see what's been correlated. Aside the mountain of irrelevant notifica…

When you say `interact[s]` you mean interactions right? Not interact transfers?

And the last date they received information about me according to Facebook is the last date I used the app. Revolut mentions "Analytics providers" in their privacy policy as companies they are sharing my data with.

For me it seems there is a 3-day difference between the last time I've used the app (today) and the last time they shared data with facebook.

You will want to use Firefox containers in order to isolate the Facebook cookie into a container to limit this.

In my profile, they managed to obtain a `PURCHASE` event from Macy's -- for an in-person purchase at a physical store . Macy's has my email address and certainly linked it to my credit card number, but this is nonetheless seriously creepy. I just tried to change my email address on Facebook and discovered that they canonicalize plus and dot variations in gmail.com addresses, and thus claim that the new email address…

It’s not a situation where FB “managed to obtain”. It’s Macy’s directly uploading transactions in order to attribute purchases to their online ad campaigns. It uses email and name etc to match.

I use Facebook container and most of the sites reporting should've never even seen my Facebook account. However, many of these sites have my email address. I highly suspect they're correlating data without knowing my Facebook account itself.

Then FB left behind tracking data, and there's your link. Sigh.

How? It was running in a browser.

Once you've logged into facebook from the device, they likely created a device fingerprint for your device: https://en.wikipedia.org/wiki/Device_fingerprint . This would allow them to identify you even without a cookie or ad id to correlate against.

Unfortunately there are no good answers for this on mobile.

Deliveroo has evidently been sending them all my orders. Or at least, there are as many 'interactions' as I have made orders. I don't log in via my Facebook so that is an unwelcome surprise.

Same here. I had to recollect if I even signed up with Facebook. After checking my Deliveroo settings, it seems that my FB account isn't even connected. This is insane...

Do you use the same e-mail address for both Deliveroo and Facebook?

If so, that could be how they matched you. Facebook lets businesses create custom retargeting audiences[1] from existing customers, and you can (obviously) include interaction data in order to segment e.g. frequent customers from occasional customers.
