... still digging ... FAQ:
- On average, how many categories does a unique user belong to?
- We see 750 million unique users per month with an average of 10-15 attributes per user.
- How long after a user qualifies for a category will that category last in their cookie?
- Categories are stored per user for 90 days. This is the legally allowed time limit. It is also a rolling 90 day period ... if the user is back online on day 2 then the activity counter resets.
It was last addition to my defences - private browsing tabs only, closing tab clears cookies and storages.
- manigandham 8y agoIs this a new discovery for you? Third-party cookie data is everywhere, and usually very messy if not completely inaccurate.
- auslander 8y agoNo, but what about first-party cookies? And all sorts of local storages? I don't need them too.
- manigandham 8y ago1st-party data is different from 3rd-party data, regardless of how it's physically stored. I'm not sure what your question is though, are you asking how to protect yourself? It seems you already have it covered if you delete cookies.
- bbulkow 8y agoFacebook's collection system is through share buttons. Those share buttons do cookie share because the domain is Facebook, but the technology is certainly there to track by ip address and device fingerprint, even if you are not a fb user, and a single fb login redropps the cookies and allows association of your internet media behavior with your FB account and behavior.
