“The main change is for users with Google Accounts,” Google said at the time of its January announcement. “Our new Privacy Policy makes clear that, if you’re signed in, we may combine information you’ve provided from one service with information from other services.” European regulators are claiming it violates data protection laws,
The updated policy describes how Google collects device information, search queries, cellphone-related data, location information, and collects and stores information on users’ devices with the use of HTML5 technology, browser storage, application data caches, and cookies and other “anonymous identifiers.”
What can you do? Most browsers today have private surfing modes that you can select. You can visit Google’s “Data Liberation Front” website for instructions in exporting data out of Google products. The Electronic Frontier Foundation also has instructions on removing your Google search history from your account.
However, even this is not as simple as it sounds. Disabling Web History in your Google account “will not prevent Google from gathering and storing this information and using it for internal purposes,” the EFF notes.
