Alphabet Inc (NASDAQ:GOOGL) Google has changed its user personal data privacy policy with the aim of fostering more protection on user data.

The initial policy was put in place almost a decade ago when the company acquired an advertising network called DoubleClick. Since then, the company managed to separate private user information with user web browsing data that is kept in DoubleClick’s database. The firm claims that the new changes will include a new language that might combine data obtained from browsing habits with data obtained from tools such as Gmail.

Alphabet subsidiary Google released a statement saying that cookies and personal information will not be integrated without authorization from users. Research carried out by ProPublica reveals that the company has abolished a statement on the promise to keep both sets of data separate. The firm has been facing some scrutiny due to this policy update mostly because the changes are focused on Google tools that aim to make sure users watch ads.

The new changes will be run by default for new Google accounts while existing users were provided with an option to change to the new settings earlier this year. The new changes mean DoubleClick will track user activity on the web. It may also be customized based on the user name or other user information that Google stores.

“The fact that DoubleClick data wasn’t being regularly connected to personally identifiable information was a really significant last stand,” stated Paul Ohm, a director at Center on Privacy and Technology.

Andrea Faville, a spokeswoman for Google released a statement saying that the new change in the company’s private policy is a move aimed at adjusting to the smartphone revolution. Faville stated that Google updated the policy so that the system can match how people use Google using different devices. The spokeswoman also stated that if users decide not to accept the new changes, their browsing experiences will not be changed.
