I think that your example is not correct.

Tinder and a lot of others apps share information with Facebook about what you do by using their SDK.

How would they do that if I didn’t log in with Facebook or in any way connect the apps together?

What I did do is add those girls’ numbers on WhatsApp - which is a Facebook property - and they suddenly appeared as friend recommendations.

But if there is any definitive proof it’s that I only was recommended the ones that I had messaged on WhatsApp, never those that I had only chatted up on the Tinder app...

Each phone has an unique advertisement identifier, they could link you across several apps with that.

But it may be very possible that they do a combination of everything to track you (whatsapp, instagram, facebook, oculus, apps that use the sdk...)
