Official Google Blog: Another step to protect user privacy
Another step to protect user privacy
Today, we're announcing a new logs retention policy: we'll anonymize IP addresses on our server logs after 9 months. Back in March 2007, Google became the first leading search engine to announce
a policy to anonymize our search server logs in the interests of
privacy. And many others in the industry quickly followed our lead.
Although that was good for privacy, it was a difficult decision because
the routine server log data we collect has always been a critical
ingredient of innovation. We have published a series of blog posts explaining how we use logs data for the benefit of our users: to make improvements to search quality, improve security, fight fraud and reduce spam.
