Earlier quoted context omitted.

are credit cards different from debit cards in this regard? Do some credit cards not sell your transactions?

It's the card network (MasterCard, Visa, AE) that sells your data. They each have their own op out: * https://marketingreportoptout.visa.com/OPTOUT/request.do * https://www.mastercard.us/en-us/about-mastercard/what-we-do/... .

Are these datas for sale in Europe as well?

Anyone else thrown off that “Download Activity Details” (which seems to be the only way you can find out what interaction was sent) leads to the main Download Your Information page, and not to anything specific to that app or that interaction?

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 notifications, here's what I've observed in this report that's concerning.

1. Albeit some data has been correlated properly (banking applications which is scary on it's own part it's sending data to facebook, imgur, Xbox, my telco provider, and a few misc blogs I've visited a handful of times per year), it's correlated a significant amount of data that may not belong to me (good thing, I suppose?)

2. Why the heck are banking applications sending data to Facebook as "CUSTOM", with no context? For example, RBC bank in Canada sends "CUSTOM" data (haven't been with them for over two years, but all interacts labelled CUSTOM) and Facebook will not give any more context on the exact data it received. Little scummy, Facebook.

Well, time to sweep this up and resist tracking more. Let's see how it works this time round.

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…

>, they managed to obtain a `PURCHASE` event from Macy's interesting.. they could use that to predict earnings..

A lot of hedge funds purchase credit card data to do exactly that.

Wow that's creepy. It lists apps where a) I didn't use FB login/signup and b) used a different email address to sign up. How do they cross-reference that to me? Hand how can I prevent that outside of their tools (which I assume still violate my privacy)?

Other commenters seem to have missed what you’re really saying here.

I’m on iPhone, and see apps listed where:

- I’ve never logged in on the web

- I’ve never clicked to open a link in a browser on-device

- Used a phone number to sign up that’s not associated with my fb account - Didn’t use email at all

Is it just me, or is there no way to download activity details? I click on an activity, then there's a few examples and a link to download, but this leads to a generic "Download your information" page and I cannot see an entry for the app or off-facebook specifically... How can I block it? some apps are on my iPhone, but I don't have the Facebook app on it (I do have messenger), and only used the apps on the phone. A…

For downloading the data there is an option to download "Ads and Businesses" under "Information About You". I just downloaded it, and it includes all data that was shared.

However, the data only shows the source, timestamp and activity ID. The actual event data is not included..

Revolut is sending data to them, too. 202 interactions for my account.

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.

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...

I am in Europe, so by law (GDPR) I have the right to make them delete all of this data. How do I do so? Also, I never consented to this being collected. How can their practice of collecting this type of data be GDPR compliant?

You can disable to storage of this data on the linked page. But I'd recommend going to the source: Read the privacy policy of each party delivering data and check if they mention it. I already sent a mail to the DPO of an app provider which shows up in this list and doesn't mentions Facebook in their privacy policy.

Even if the app had it in their privacy policy, that would not mean it is legal to send your data to Facebook.

GDPR requires the users consent to do so. Having a statement in a privacy policy is imho not enough to qualify as consent.
