DuckDuckGo does not store your search history or build a profile of your searches, but it does collect some data — just less than Google does

DuckDuckGo's core promise is that it does not log your IP address, does not track which searches you perform, and does not create a persistent profile of your browsing behavior. When you search on DuckDuckGo, the company cannot tell you what you looked for yesterday or build a dossier of your interests over time. That is genuinely different from Google, which ties your searches to your Google account and uses that history to target ads.

But "does not track you" does not mean "collects nothing." DuckDuckGo still receives data about your search — the search terms themselves, the time, your approximate location based on IP address — in the moment you search. It just does not store that data in a way that connects it to you personally across sessions. The company also collects some information about how you use its website and apps, and it has business relationships with other companies that do track you.

Understanding what DuckDuckGo actually does — and what it does not — matters because the difference between "anonymous" and "less tracked" is real, and it affects what privacy you actually get.

Key Takeaways

  • DuckDuckGo does not store your search history or tie searches to your account, so the company cannot build a profile of your interests over time.
  • DuckDuckGo still sees your search terms and approximate location in the moment you search, but says it deletes this data regularly and does not sell it to advertisers.
  • DuckDuckGo makes money from ads based on the search terms you use right now, not on a profile built from your past behavior.
  • Third-party trackers on websites you visit from DuckDuckGo results can still follow you, because DuckDuckGo cannot control what happens after you leave its site.
  • If you use DuckDuckGo on a work network or school network, your IT department can still see what you search for, because they control the network.

What DuckDuckGo collects and what it does not

DuckDuckGo does not store your IP address in a way that connects it to your searches. This is the core difference from Google. When you search "best therapists near me" on DuckDuckGo, the company processes that search, returns results, and then does not keep a record that your IP address performed that search. Google, by contrast, stores that search tied to your account or device ID, and uses it to understand your interests.

DuckDuckGo also does not use cookies to track you across searches. If you search for "knee pain" and then later search for "orthopedic surgeons," DuckDuckGo does not connect those two searches to build a profile. Google does this routinely — it is how Google knows you are interested in health topics and can show you relevant ads weeks later.

What DuckDuckGo does collect: your search terms in the moment you search them, your approximate location (derived from your IP address), the time of the search, and basic information about your device and browser. The company says it deletes logs of this data after a few months, though the exact retention period is not public. DuckDuckGo also collects information about how you interact with its website and apps — which buttons you click, how long you stay on a page, whether you use dark mode.

How DuckDuckGo makes money without selling your data

DuckDuckGo's business model depends on ads, but ads based on what you search for right now, not on a profile built from your past. When you search "running shoes," DuckDuckGo shows you ads for running shoes. When you search "car insurance," you see car insurance ads. This is called contextual advertising — the ad matches the search, not the person.

Google's model is different. Google builds a detailed profile of your interests, location, age, income level, and behavior across the web, then sells advertisers the ability to target you based on that profile. DuckDuckGo does not do this. It does not sell your data to advertisers, and it does not build a long-term profile to sell access to.

DuckDuckGo does have business relationships with other companies. It uses Bing's search index to supplement its own results, and it partners with Amazon and eBay for shopping results. These partnerships mean that some data flows to those companies, though DuckDuckGo says it does not pass identifying information along with it.

What DuckDuckGo cannot protect you from

DuckDuckGo's privacy protections stop at its own website. Once you click a search result and leave DuckDuckGo, the website you visit can track you however it wants. If you search for a product on DuckDuckGo and then click through to Amazon, Amazon can see that you visited, what you looked at, and what you bought. Amazon can then use that information to target ads to you across the web.

DuckDuckGo does offer a feature called Bangs that lets you search other sites directly without clicking through — typing "!a running shoes" searches Amazon directly without visiting DuckDuckGo's results page first. But this is optional, and most people click through normally.

DuckDuckGo also cannot protect you from trackers embedded in websites themselves. Many websites include tracking pixels or scripts from companies like Google Analytics, Facebook Pixel, or Hotjar. These trackers follow you across the web regardless of which search engine you use. DuckDuckGo's browser extension can block some of these trackers, but not all, and it only works in the browser where you install it.

Network-level tracking still happens on work and school networks

If you use DuckDuckGo on a work computer or a school network, your employer or school can still see what you search for. They control the network, not DuckDuckGo. Network administrators can log all traffic passing through their routers, which includes your search terms, the websites you visit, and the data you send and receive.

Using DuckDuckGo on a work network provides no additional privacy from your employer or school. The only way to hide your searches from a network administrator is to use a VPN (virtual private network) that encrypts your traffic before it leaves your device, but even then, many employers block or monitor VPN use.

How DuckDuckGo compares to other search engines

Google collects the most data. It stores your search history, ties it to your account, and uses it to build a detailed profile for ad targeting. It also tracks you across the web through Google Analytics, Google Ads, and other services embedded in websites.

Microsoft Bing collects less data than Google but more than DuckDuckGo. Bing ties searches to your Microsoft account if you are signed in, and it uses search data for ad targeting, though not as aggressively as Google.

Startpage and Qwant are other privacy-focused search engines. Startpage uses Google's search results but strips out identifying information before sending the query to Google. Qwant is a European search engine that does not store IP addresses. Both offer privacy similar to DuckDuckGo, though with different technical approaches.

No search engine is completely anonymous. All of them see your search terms in the moment you search. The difference is what they do with that data afterward — whether they store it, tie it to you, and use it to build a profile.

What you can do to increase your privacy beyond DuckDuckGo

Using DuckDuckGo is a good first step, but it is only one part of online privacy. You can also use a VPN to hide your IP address from websites and your internet service provider, though a VPN does not hide your searches from DuckDuckGo itself — DuckDuckGo still sees the search terms.

You can block third-party trackers by using a browser extension like uBlock Origin or Privacy Badger. These extensions block tracking scripts from companies like Google, Facebook, and others that follow you across websites. DuckDuckGo's own browser extension includes some tracker blocking, but third-party extensions are often more comprehensive.

You can also limit what data you share with websites by using privacy-focused browser settings. Most modern browsers let you block third-party cookies, enable "Do Not Track" headers, and restrict what sites can access (like your location or camera). These settings do not make you anonymous, but they reduce the amount of data websites can collect about you.

Frequently Asked Questions

Does DuckDuckGo sell my search data to advertisers?

No. DuckDuckGo does not sell your search history or personal data to advertisers. It makes money from contextual ads — ads matched to your current search, not to a profile built from your past behavior. This is fundamentally different from Google's model.

Can DuckDuckGo see my search history?

DuckDuckGo sees your search terms when you search, but it does not store them in a way that connects them to you across sessions. The company says it deletes search logs after a few months. You can verify this by checking that DuckDuckGo does not offer a "search history" feature in your account settings — because it does not keep one.

Is DuckDuckGo truly anonymous?

No. DuckDuckGo does not store your search history or build a profile, but it is not truly anonymous. Your IP address is visible to DuckDuckGo in the moment you search, and websites you visit from search results can track you. True anonymity requires additional tools like Tor Browser.

Does DuckDuckGo work with law enforcement?

DuckDuckGo has stated that it does not have backdoors for law enforcement and that it cannot provide search history because it does not store it. However, like any company, DuckDuckGo could be compelled by court order to provide data it does have — such as logs from a specific IP address during a specific time period.

If I use DuckDuckGo, will I see fewer ads?

You will see ads on DuckDuckGo, but they will be based on your current search, not on a profile of your interests. You may see fewer ads overall than on Google, because DuckDuckGo does not have as much data to sell advertisers. The ads you do see are less likely to follow you across the web.
