Just got retargeted on desktop FB by a company, whose site I visited on my mobile phone using Chrome 'incognito' mode earlier today. Didn't knowingly visit a similar website. Might still be some random/correlation stuff, or can FB pixel somehow identify users in 'incognito' mode?

Perhaps your mobile carrier sells data to a broker, so while the browser is incognito, your mobile carrier knows who you are. Or uses unique headers, although I thought they stopped doing it, eg: ftc.gov/system/files/documen…

It guess, this would be a huge scandal (in Austria and in the EU). I'd never say it's 100% certain that it doesn't happen, but I'd consider it as highly unlikely.
