How much data does Analytics actually store?

[csdude55]

I received spam today for Web Leads extension, and it made me start to question...

This is their claim:

You can now get a complete list of all your website visitors within the last 12 months using the the new Web Leads extension 2.0

Web Leads users have access to data on all their web site visitors including all company names, addresses, phone numbers, websites, contact person, email addresses and important metrics that track your website’s most popular pages – even going back up to 12 months!

I'm not gonna post a link and reward spammers. One oddity already is that the email calls it 2.0, and their website says it's 3.0! LOL

But the claim that they can gather contact details on users using nothing but Analytics, going back to 12 months before you registered? That implies that Analytics stores this data somewhere.

Thoughts?

They get IP addresses from GA. Where they can identify a company from its IP address range, they then get the contact data from another database. The founder of the company also founded a company information business that has contact information in their database.

Incidentally, there is another company selling a similar product using a similar brand - "Web Leads" vs "Web Leads Extension"

All these are limited to identifying businesses that have a fixed and identifiable address range. Small businesses will invariably just have an IP tied to their ISP.
