I had the same LAN TIM 2 in my personal data export - and I too had purchased something from Spreadshirt before.

Edit: How they matched it up though is a mystery to me, as I use another e-mail address for FB than for the rest of the online world.

What if you were logged into Facebook and checkout page contained a script that sent data to Facebook?

To fix this by the way, just install the Facebook Container in Firefox. Somebody else (presumably a Mozilla employee?) does the extensive curation needed to get this to work and stay working. You are logged into Facebook inside the Container, but everything else is pristine, on the outside of the Container you can log into whatever and it's not connected back to Facebook.

Firefox's Container system is a powerful solution to this general problem, but normally you need to do curation work proportional to the effort being taken to track you. Their Facebook Container though comes with that curation done.

If you use Login with Facebook (you want Privacy, but you choose to Login with Facebook? Maybe reconsider your life choices) the Container puts everything you logged into this way inside the Container too, so that dissolves your privacy but you chose to have it happen.

They even have a better version, the Multi Container plugin. You can separate multiple contexts (fb, goog, banking, memes..), and each lives in a separate container. Takes a little time to get used to, and if used with privacy badger, ublock origin, FF built-in anti-tracking, might give good results in reducing your exposure to online tracking.

Yet some mobile apps still use heavy analytics which is sent to some domains, again, you need something like netguard, vpns, to filter your mobile traffic. Privacy becomes a pain https://media.ccc.de/v/35c3chaoswest-32-toll-of-personal-pri...
