Some user said this isn't a secure service as it is a USA-based company. Well, as they stat on their privacy policy: https://duckduckgo.com/privacy, they don't collect any data, so they cannot share any data with anyone... besides, this user also stats this is a cookie-free service, but cookies are the only you can turn on.
This search engine is the great alternative to google, it returns very good results, and I only miss some google's features like filter results from date, or a few examples more.
