Yes, from:
https://duckduckgo.com/privacy>When you search at DuckDuckGo, we don't know who you are and there is no way to tie your searches together.
> When you access DuckDuckGo (or any Web site), your Web browser automatically sends information about your computer, e.g. your User agent and IP address.
> Because this information could be used to link you to your searches, we do not log (store) it at all. This is a very unusual practice, but we feel it is an important step to protect your privacy.
They also provide tools to help prevent other sites from tracking you:
>Finally, if you want to prevent sites from knowing you visited them at all, you can use a proxy like Tor. DuckDuckGo actually operates a Tor exit enclave, which means you can get end to end anonymous and encrypted searching using Tor & DDG together.
>You can enter !proxy domain into DuckDuckGo as well, and we will route you through a proxy, e.g. !proxy breadpig.com. This feature is part of our !bang syntax. Unfortunately, proxies can also be slow, and free proxies (like the one we use) are funded by arguably excessive advertising.
