See, I have been listening to the DuckDuckGo hype for many years. It is said to be the privacy-first search engine, one that does not spy on you as Google does. That’s the point I’m skeptical about.

So I spent two weeks finding out whether DuckDuckGo is still privacy-promising. Here’s what I found.

What I Tested (And How)

First, I installed the DuckDuckGo browser extension and set it as my default search engine. Then I got technical. I monitored what was being reported, examined my browser network usage, and compared it with Google.

It struck me how different it was. My search results included my search terms across search result pages, URLs, referrers, and analytics applications. With DuckDuckGo? Those search terms vanished as soon as I opened a site.

The Features of Privacy That Work.

DuckDuckGo is a search engine that blocks third-party trackers. I tried this on a few of the most infamously tracker-intensive websites- you know these types of websites that track you wherever you go. The extension showed me exactly what it blocked: Facebook Trackers, Google Analytics, and ad networks I’d never heard of.

My favorite tool was the Privacy Grade feature. It rates each website on a scale of A through F based on its tracking practices. I visited sites I visit daily, and, frankly? The vast majority received a D or F, and then DuckDuckGo intervened. A good number were blocked and then jumped to B or A.

What impressed me most: the Fire Button. A single tap will delete your latest browsing history. No searching through options, no confirmations. Just gone.

What DuckDuckGo fails to secure for you.

Here, however, is where testing me by my discoveries showed the limitations–and they are very great.

Your keywords are still in your browser’s address bar. Anyone with access to your machine can view your search history. I tried it, though, with something embarrassing (in science), and look, it is right there in my browser history.

DuckDuckGo is not concealing your IP. Websites I shopped on could still tell my general location. I verified this with IP checker tools- all the sites I visited were aware of the fact that I was browsing in my city.

The bigger issue? The internet service provider still has access to everything. I did some packet-capture tests, and while DuckDuckGo uses HTTPS encryption, my ISP can still see what sites I access and when.

Another gap is browser fingerprinting. Cutting-edge tracking systems can identify you by details like your screen resolution, installed fonts,  and browser settings. DuckDuckGo has no means to block each of them.

Microsoft Tracker Controversy.

I also read about the 2022 scandal in which researchers found that DuckDuckGo let Microsoft trackers through. DuckDuckGo blocks Google and Facebook trackers but lets some Microsoft advertising requests pass on third-party websites.

They have been open about this kind of syndication deal, but it’s still a privacy backdoor that people should know about.

My Honest Take

Two weeks later, I can conclude: DuckDuckGo is much safer than Google for private searches. It doesn’t follow you or build a profile. The tracker blocking works, and the Privacy Grade tool isn’tseless.

However, it is not an end-all, be-all for privacy. At the network level (you are still exposed to your ISP, who can see everything), at the device level (search terms in your URL history), and by using sophisticated methods of fingerprinting.

You’ll get real privacy improvements if you do the same. The only thing is, you shouldn’t expect to be invisible. To do that, you will need to use DuckDuckGo along with a VPN and perhaps Tor.

FAQs

Does DuckDuckGo actually hide my searches from my internet provider?

No. Your ISP can monitor your visits and search history, although DuckDuckGo) does not track your own searches. They won’t see what you were actually searching for, but they will see that you are using DuckDuckGo and then going to certain websites.

If ISP tracking matters to you, you’ll need a VPN on top of DuckDuckGo.

Can websites I visit see what I searched for on DuckDuckGo?

No, and this is one area where it works well. DuckDuckGo anonymizes your clicks to websites, which means they don’t even know what you searched.

I checked referrer headers to confirm this; websites weren’t aware of what I searched before I joined them. Nevertheless, they can still see your IP address and device information.

Is DuckDuckGo completely anonymous?

Not even close. DuckDuckGo keeps your search history private, but it doesn’t make you anonymous. Websites can still see your IP address and location. Your network provider traces your activity. Anyone with access to your device can view your browsing history.

Even sophisticated tracking can profile you through sessions. Consider DuckDuckGo as privacy-enhanced, not privacy-optimal.
