The mechanism whereby the NATS app would show tail numbers for Mode C targets would be interesting. It would be possible for aircraft talking to the radar unit. Whether this is real, only ATC would know and while half of NATS reads EuroGA, none have ever posted 
OTOH NATS reportedly charge 100k a year for a radar feed so there has to be a catch…

And that is the beauty of the GDPR. The regulation applies to data controllers or processors established outside the EU but who are processing the personal data of EU citizens. It’s going to be hard to escape. This is a tectonic shift in privacy regulations.
I don’t need to know because FR24 does it for me :-p
