Search engine Ask to stop keeping search data upon request
From the Mercury News:
Ask.com became the first major search engine to promise users it won't store data on their queries, giving the privacy conscious the option of conducting research on the Internet in relative anonymity.The move comes amid increasing concerns about the release of search information through leaks or subpoenas. In some cases, the search terms a person uses can reveal plenty about medical conditions, marital troubles or kinky interests.
