Even if they do (for Android users only), how would they connect location data to my credit card history? Are you claiming that Google reverse engineers PII by correlating Android location data with credit card purchase location history?
- dehrmann 7y agoThis doesn't quite say they do exactly that, but they do tie location data to offline purchases. > Since 2014, Google has flagged for advertisers when someone who clicked an ad visits a physical store, using the Location History feature in Google Maps. Still, the advertiser didn’t know if the shopper made a purchase. So Google added more. A tool, introduced the following year, let advertisers upload email addresses of customers they’ve collected into Google’s ad-buying system, which then encrypted them. Additionally, Google layered on inputs from third-party data brokers, such as Experian Plc and Acxiom Corp., which draw in demographic and financial information for marketers.

- dillonmckay 7y agoThey know your approximate location when you conduct an offline credit card transaction, and the approximate time and location of the store where the transaction occurred.
