Google Secretly Tracks What You Buy Offline Using Mastercard Data

[Sept 04, 2018]

Over a week after Google admitted the company tracks users’ location even after they disable location history, it has now been revealed that the tech giant has signed a secret deal with Mastercard that allows it to track what users buy offline.

Neither Google nor Mastercard has publicly announced the business partnership over allowing Google to measure retail spending, though the deal has now been disclosed by Bloomberg.

Google packaged the data into a new tool for advertisers, called Store Sales Measurement, and currently being tested the tool with a small group of advertisers, allowing them to track whether online advertisements turned into real-world retail sales.

By the way, Mastercard denied that the company provided personal information to any third parties.

Cyber Security Tips: 

  • Users can reportedly opt out of offline ad tracking by merely turning off “Web and App Activity” in their Google account.
