DuckDuckGo is a private search engine. It is adamant about spreading privacy around the internet. However, there is one issue we discovered that raises privacy concerns. Your search terms, while they may be sent over your network in an encrypted form, show up in plain text in browsing history.
DDG may work well for reducing advertiser tracking, avoiding filter bubbles, and limiting data profiling, however as this post explains, it may not offer the protection from surveillance organizations that some think. DuckDuckGo, along with many other private search engines, saw a massive influx of users after Edward Snowden sparked general interest in privacy, specifically from government surveillance agencies. Snowden endorsed the use of private search tools for their lack of tracking. However, he also endorsed the use of other data protection measures to create a complete privacy suite. Snowden explains that no privacy tool, or system, is perfect. But more privacy is a good thing, across the board, even if it doesn’t quite protect you from all angles.
By comparison, StartPage and Search Encrypt don’t display search terms in your history. If you try to go to the links in your history, you will be returned to the search engine’s homepage. That is not the case for DuckDuckGo and Google, which take you right back to the results you were viewing before. This may seem like a minor issue, because users could just clear their history. However, privacy by design means that the most private settings are enabled by default. This extra step makes privacy inconvenient, and the product less user friendly. Privacy by design is essential, especially for privacy based products. The expectation of private search engines is that they deliver on their privacy promises, in this case, DuckDuckGo has failed.
If your DuckDuckGo searches appear in your history, that means Google can access and track your searches even on this search engine. This is especially true if you use Chrome for your browser. Users who want to search the web privately, but who are less technically adept, may assume they are protected, when there is really a clear vulnerability in DuckDuckGo.

DuckDuckGo Displays Search Terms in URL
When you search on DuckDuckGo your search term is visible in the address bar of your browser. As a result, your search term shows up in your history. If the point of DuckDuckGo is to remain more private while searching the web, it doesn’t make sense to have your search terms visible to anyone with access to your computer (or your network). Search Encrypt encrypts your search term right away and then does not display what you searched for in your browser or in your history. We keep your search term in encrypted form, and when you’ve finished searching your search term encryption key expires so that no one has access to what you searched for.
Your search URL on DuckDuckGo: https://duckduckgo.com/?q=your+search+term&t=h_&ia=web
Your search URL on Search Encrypt: https://www.searchencrypt.com/search?eq=a87bqOs2rgTwaGJUXynoh5UJhJnK20sr2B%2BcvCdzoyk%3D
Using DuckDuckGo or Google leaves your search terms unencrypted and visible to anyone on your computer. Using Search Encrypt as an alternative gets rid of the need to clear your history. If you forget to clear your browsing history after searching on Search Encrypt, don’t worry – your search term is encrypted and will disappear after you’re done searching.
Notice that since we’ve visited cars.com before, the link appears in purple rather than blue. This may seem to be a convenient feature, but we see a privacy issue here. If someone else is using your computer, they can see which websites you’ve visited, and can determine what sort of searches you’ve been doing.
It’s confusing to us why DuckDuckGo, if it’s focused on privacy would provide a tool that directly takes people away from a private environment back into Google’s data collection. There is no warning message or prompt that let’s users know that using bangs redirects them to sites that track their data. If DuckDuckGo is going to carry the name of a “private” search engine, they should put that into practice from end-to-end and not just selectively.
While DuckDuckGo is certainly another option for searching the web, it is not a totally private search engine. It has some privacy protection measures in place, but you should be able to trust that DuckDuckGo will protect your privacy, since their company is based around it. As a result, you can either trust Google’s extremely advanced security or put your privacy in the hands of DuckDuckGo which has overlooked a few key points. When it comes to private search engines, DuckDuckGo is another option, but is not the best. Search Encrypt and StartPage both use much more advanced encryption measures and they are enabled by default.
