How would the cookie from the work get to the phone?

You don't need to rely on cookies anymore to identify someone online: https://en.wikipedia.org/wiki/Device_fingerprint

Sure, but that's not cross device.

I must have been connected to the same Gmail or Facebook account at some point on both devices. However as I said I purposely never stay logged in to google services. Yeah, I can flush all cookies (thus annoyingly resetting all legit cookies as well).

But this is not how privacy should work, cause there is a lot of people out there that don't read HN and only recently found out that there is a lot pastry inside their computers.

Your browser (Firefox, Chrome, Safari) most likely uses Google SafeSearch. That phones home with a super cookie every 30 minutes.
