Making good on its promise to offer anonymous search, Ask.com has launched its AskEraser privacy feature, which gives users the chance to take charge of what happens with their search history.

While Google and Microsoft have committed to make search logs largely anonymous or discard them after 18 months, AskEraser goes one step further by allowing users to request that their search records are not stored on Ask.com's servers in any form for any period of time.

The search engine market is vastly dominated by Google, and rivals are increasingly looking for ways to differentiate themselves. With consumers getting cautious about how their data is shared online, Ask is betting on digital privacy to step forward as an alternative to Google.
