It's fairly straight forward - cookies + Google's ad network + Analytics on your phone allow them to track you across devices.
- bla2 10y agoHow would the cookie from the work get to the phone?
- Twisell 10y agoI 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.

- bla2 10y agoSure, but that's not cross device.
- Twisell 10y agoOk, so maybe we are talking about the same field of science, but it seems that, from what they say there is two very distinct approach. 1.Collect personal data, send them to mainframe, use them to profile and deliver custom tailored services. When sharing hash so that individual records can't be extrapolated 2.Collect personal data, use them locally sometimes using mainframe provided 'models'. Return to mainframe hashed records to improve models. Google is clearly using 1. while Apple claim to target 2. (I don't think it's actually the case now because I though Siri actually store some personal data on the cloud so far)
