Microsoft is changing its data-retention policy for its Bing search engine. According to, all data collected on users will now be cleared out after six months. The new policy will be implemented over the next 12 to 18 months, says Peter Cullen, chief privacy strategist at Microsoft.


As The New York Times notes, Microsoft is the first company to fully comply with a request by a European advisory group known as Article 29 Working Group. In 2008, the group proposed new rules to regulate search engines, including deleting personal data after six months, informing users about data collection and storage practices, and dissociating a user's IP address from stored search queries.
