Google Drops Ban on Personally Identifiable Web Tracking
And, for nearly a decade, Google did in fact keep DoubleClick’s massive database of web-browsing records separate by default from the names and other personally identifiable information Google has collected from Gmail and its other login accounts.
But this summer, Google quietly erased that last privacy line in the sand – literally crossing out the lines in its privacy policy that promised to keep the two pots of data separate by default. In its place, Google substituted new language that says browsing habits “may be” combined with what the company learns from the use Gmail and other tools.
The change is enabled by default for new Google accounts. Existing users were prompted to opt-in to the change this summer.
And, I guess, new users can opt out.
Google also happens to run the most popular website analytics suite, estimated to be used on tens of millions of websites. They say that they are currently keeping browsing data separate from other Google activity, but they’re leaving the door open for that to change in the future.
