DuckDuckGo: Meet the Privacy-Focused Rival to Google Search

What is DuckDuckGo, and how does it work? Here’s everything to know about the privacy-minded search engine.

Online trackers can be annoying. You search for a product or click on an advertisement one time, and then ads for that product seem to follow you to the ends of the internet, even across devices. Sometimes, you just want a little privacy in your browsing. Enter DuckDuckGo, a search engine that pledges to keep your search activity anonymous and not track you online. 

There are other private browsers, such as Brave and the Mullvad Browser, that block others from monitoring your online activity. But DuckDuckGo — which has spent heavily on an advertising campaign — sees itself as a direct competitor to Google Search, complete with a mobile app and extensions for Chrome, Firefox, Safari and other browsers, as well as a Mac browser in public beta

After major incidents like the Cambridge Analytica scandal, people have become more aware of how much personal information is available to tech companies and advertisers — and are opting out of being tracked when they can. While it doesn’t track users, DuckDuckGo’s app was downloaded more than 50 million times between July 2020 and June 2021 — more than all other years combined since its 2008 launch. 

Here’s what you need to know about DuckDuckGo and how it tries to keep your searches more secure.

What is DuckDuckGo? 

DuckDuckGo is a search engine that offers a mobile browser app and a desktop extension, both aimed at allowing you to browse the internet without companies gobbling up your personal data. It promises to keep your searches private, anonymous and offers built-in tracker blocking, so the sites you visit have a harder time collecting information about you.

How does DuckDuckGo work?

For starters, DuckDuckGo does not track searches made through its browser extension or mobile app. Other browsers, including Chrome, allow you to use private or incognito windows that don’t track your search history, but their default windows do. (That’s the basis of every «embarrassing search history» joke.) Instead of making you navigate to a different version of its app, DuckDuckGo never tracks your search history.

Searches made through DuckDuckGo also automatically connect you to the encrypted versions of websites wherever possible, making it harder for anyone else to see what you’re looking at online. This is another scenario where both options (encrypted and unencrypted) exist on other search engines, but the default isn’t always the privacy-friendly option. DuckDuckGo saves you the extra steps of manually navigating to encrypted connections.

DuckDuckGo was criticized in May 2022 when researchers discovered some Microsoft tracking scripts while using DuckDuckGo’s browsers. The presence of Microsoft trackers seemed to fly in the face of the search engine’s privacy promise, and DuckDuckGo’s founder and CEO clarified on Reddit that the company was «currently contractually restricted by Microsoft» from stopping Microsoft scripts from completely loading. This is because the company uses Microsoft’s Bing to power its search results. The company followed up in August, however, by announcing that it would further restrict Microsoft trackers in its browsers.

However, DuckDuckGo remains ahead of other popular privacy options when it comes to blocking tracking data, and the company has clarified its app store descriptions to better clarify limitations in its privacy protections. DuckDuckGo had also previously disclosed its partnership with Microsoft, and its CEO said in the Reddit post that the company is working to get that restriction changed.

DuckDuckGo also actively blocks external trackers from following you around online. For a more detailed explanation of DuckDuckGo’s privacy features, check out DuckDuckGo’s blog

How is DuckDuckGo different from Google Search? What about Incognito mode and private browsing?

DuckDuckGo essentially takes the opposite approach compared to other big tech companies like Google and Facebook, which have traditionally made money by targeting ads based on your browsing history and personal data. While Google has said it’s going to stop this practice, the platform still collects a ton of data about you, including your location and search activity — yes, even in incognito mode. 

Incognito mode simply deletes information related to your browsing session from your computer: your history, cookies and any info you’ve entered into fields. Notably, it only does that after you end your session by closing out all your tabs. So if you leave your incognito tabs open for hours or days at a time, that information will still build up. And no matter what, Google can save your searches — and companies, internet service providers and governments can still track you across the internet, even when you’re using incognito mode.

DuckDuckGo is different because it doesn’t store your browsing data at all, and it blocks trackers while you’re browsing.

If it isn’t targeting ads, how does DuckDuckGo make money?

DuckDuckGo still makes money from advertising — it just doesn’t use targeted ads. The search engine shows you ads based on the keywords you search for, which aren’t connected to your personal data like your browsing or purchase history. Essentially, you’ll only see ads for whatever you’re currently searching for, not the weird product your friend sent you a link to last week that you now can’t get away from. 

How can I use DuckDuckGo?

On mobile devices, simply open your app store and search for «DuckDuckGo.» You’ll be able to download the DuckDuckGo Privacy Browser app and use it the same way you’d use Chrome or Safari. At the bottom center of your app, you’ll see a fire icon, which you can press at any time to close all your tabs and clear all personal data.

On desktop, go to duckduckgo.com, where you’ll see a button to add DuckDuckGo to your browser. On Chrome, you’ll be directed to the Chrome webstore page to download the extension for free. On Safari, you’ll be instructed on how to set DuckDuckGo as your default search engine or to manually activate a search using DuckDuckGo.

Gen AI Chatbots Are Starting to Remember You. Should You Let Them?

An AI model’s long memory can offer a better experience — or a worse one. Good thing you can turn it off.

Until recently, generative AI chatbots didn’t have the best memories: You tell it something and, when you come back later, you start again with a blank slate. Not anymore. 

OpenAI started testing a stronger memory in ChatGPT last year and rolled out improvements this month. Grok, the flagship tool of Elon Musk’s xAI, also just got a better memory.

It took significant improvements in math and technology to get here but the real-world benefits seem pretty simple: You can get more consistent and personalized results without having to repeat yourself.

«If it’s able to incorporate every chat I’ve had before, it does not need me to provide all that information the next time,» said Shashank Srivastava, assistant professor of computer science at the University of North Carolina at Chapel Hill.

Those longer memories can help with solving some frustrations with chatbots but they also pose some new challenges. As with when you talk to a person, what you said yesterday might influence your interactions today.

Here’s a look at how the bots came to have better memories and what it means for you.

Improving an AI model’s memory

For starters, it isn’t quite a «memory.» Mostly, these tools work by incorporating past conversations alongside your latest query. «In effect, it’s as simple as if you just took all your past conversations and combined them into one large prompt,» said Aditya Grover, assistant professor of computer science at UCLA.

Those large prompts are now possible because the latest AI models have significantly larger «context windows» than their predecessors. The context window is, essentially, how much text a model can consider at once, measured in tokens. A token might be a word or part of a word (OpenAI offers one token as three-quarters of a word as a rule of thumb). 

Early large language models had context windows of 4,000 or 8,000 tokens — a few thousand words. A few years ago, if you asked ChatGPT something, it could consider roughly as much text as is in this recent CNET cover story on smart thermostats. Google’s Gemini 2.0 Flash now has a context window of a million tokens. That’s a bit longer than Leo Tolstoy’s epic novel War and Peace. Those improvements are driven by some technical advances in how LLMs work, creating faster ways to generate connections between words, Srivastava said. 

Other techniques can also boost a model’s memory and ability to answer a question. One is retrieval-augmented generation, in which the model can run a search or otherwise pull up documents as needed to answer a question, without always keeping all of that information in the context window. Instead of having a massive amount of information available at all times, it just needs to know how to find the right resource, like a researcher perusing a library’s card catalog.

Why context matters for a chatbot

The more an LLM knows about you from its past interactions with you, the better suited to your needs its answers will be. That’s the goal of having a chatbot that can remember your old conversations. 

For example, if you ask an LLM with no memory of you what the weather is, it’ll probably follow up first by asking where you are. One that can remember past conversations, however, might know that you often ask it for advice about restaurants or other things in San Francisco, for example, and assume that’s your location. «It’s more user-friendly if the system knows more about you,» Grover said.

A chatbot with a longer memory can provide you with more specific answers. If you ask it to suggest a gift for a family member’s birthday and tell it some details about that family member, it won’t need as much context when you ask again next year. «That would mean smoother conversations because you don’t need to repeat yourself,» Srivatsava said.

A long memory, however, can have its downsides.

You can (and maybe should) tell AI to forget

Having a chatbot recommend a gift poses a conundrum that’s all too common in human memories: You told your aunt you liked airplanes when you were 12 years old, and decades later you still get airplane-themed gifts from her. An LLM that remembers things about you could bias itself too much toward something you told it before.

«There’s definitely that possibility that you can lose your control and that this personalization could haunt you,» Srivastava said. «Instead of getting an unbiased, fresh perspective, its judgment might always be colored by previous interactions.»

LLMs typically allow you to tell them to forget certain things or to exclude some conversations from their memory. 

You may also deal with things you don’t want an AI model to remember. If you have private or sensitive information you’re communicating with an LLM (and you should think twice about doing so at all), you probably want to turn off the memory function for those interactions. 

Read the guidance on the tool you’re using to be sure you know what it’s remembering, how to turn it on and off and how to delete items from its memory. 

Grover said this is an area where gen AI developers should be transparent and offer clear commands in the user interface. «I think they need to be providing more controls that are visible to the user, when to turn it on, when to turn it off,» he said. «Give a sense of urgency for the user base so they don’t get locked into defaults that are hard to find.»

How to turn off gen AI memory features

Here’s how to manage memory features in some common gen AI tools.

ChatGPT

OpenAI has a couple types of memory in its models. One is called «reference saved memories» and it stores details that you specifically ask ChatGPT to save, like your name or dietary preferences. Another, «reference chat history,» remembers information from past conversations (but not everything). 

To turn off either of these features, you can go to Settings and Personalization and toggle the items off. 

You can ask ChatGPT what it remembers about you and ask it to forget something it has remembered. To completely delete this information, you can delete the saved memories in Settings and the chat where you saved that information.

Gemini

Google’s Gemini model can remember things you’ve discussed or summarize past conversations. 

To modify or delete these memories, or to turn off the feature entirely, you can go into your Gemini Apps Activity menu.

Grok

Elon Musk’s xAI announced memory features in Grok this month and they’re turned on by default. 

You can turn them off under Settings and Data Controls. The specific setting is different between Grok.com, where it’s «Personalize Grok with your conversation history,» and on the Android and iOS apps, where it’s «Personalize with memories.»

It’s OK if You Didn’t Preorder a Switch 2

Commentary: As good as the new console looks, it’s also fine to wait.

FOMO for new tech is hard. And new game consoles are exciting. I get it, and I’ve contributed to that coverage excitement too. The Nintendo Switch 2 finally became available to preorder in the US this week, and as expected, it looks sold out for now. That’ll change over time, but it’s unclear when, or how, and it’s equally unclear what the constant tariff fluctuations might do to future game console pricing. 

That said, having played on the Switch 2 recently at an event, may I help ease your FOMO somewhat by saying you’re probably OK waiting on it?

I felt this way after my full-day Switch 2 experience, and I’ll reiterate it now: As good as the upgrades the Switch 2 has, and as fun as the new Mario Kart and Donkey Kong games seem to be — and the GameCube gaming library also seems like a blast of retro fun — the Switch 2 is very much an iterative upgrade for now. The very best games on the Switch 2, and its most unique exclusives, are likely still to come.

Nintendo has clearly designed the Switch 2, at least for the moment, to exist as a bridge to the current Switch, with many upcoming games intended to work on the original Switch too. Much more than the debut of the first Switch, the Switch 2 is designed to be a system you could wait to upgrade to. In that sense, it’s following the path of the current gen of Xbox Series X and S and PlayStation 5 consoles.

You can build up your Switch library now and be Switch 2-ready when you eventually upgrade

The Switch 2 plays all the Switch games, which wasn’t the case with the Switch and previous Wii U and 3DS hardware. That means you could skip the Switch 2 now if you needed to, play games on the Switch, and then move your library over whenever. Switch 2 versions of games cost more (ranging from $10 to $20 more), but you can just buy the Switch 2 game upgrades later for a similar price — or play the versions you’ve already got minus the enhanced graphics and game extras.

The Switch 2’s current upgrades are good, but not shockingly good

After playing several of the Switch 2 Edition versions of Switch games for a bit, I noticed better frame rates and graphics resolution, but I honestly didn’t find it to be that much different. I’d prefer playing the enhanced Switch 2 editions, but the experience reminded me a bit of the PS5 Pro versus PS5 versions of games when I first played on the console with Sony last year.

If you have a big TV, you’ll likely appreciate the difference. The bigger Switch 2 screen shows off games in higher-res 1080p with HDR, but you could play on the older Switch and be fine. I’m playing on a Switch OLED again, and after the Switch 2 experience, I don’t have massive I-wish-this-were-a-Switch-2-envy. 

I’m sure this will change as games are developed to take better advantage of the amped-up Nvidia-powered Switch 2 GPU, and when more exclusives arrive. It’s similar to how I felt about the Meta Quest 3, which has better graphics than Quest 2 but didn’t feel like an absolute must-get until a year into its release.

You can still play upcoming Nintendo games on OG Switch

While Mario Kart World and Donkey Kong Bananza are Switch 2 exclusives, Metroid Prime 4 Beyond and Pokemon Legends Z-A also play on the Switch. It’s unclear how well these games will play on the Switch versus Switch 2, but you can get a good dose of New Nintendo this year on the older hardware and upgrade the hardware upgrade later. Think of it as a bit of a FOMO buffer.

Looking at Nintendo’s game history, the company often supported its previous consoles for a good couple of years after the new hardware’s release. I’d expect that after 2026 the Switch 2 will start to become the go-to platform for most big game, but I wouldn’t be surprised to see a handful of key Nintendo games still supporting original Switch for another year at least.

There’s no ‘whole new experience’ you’ll miss other than Game Chat, that camera and the mouse 

The original Switch was an eye-opener because it was a portable, full game console that could dock with your TV and turn into a shareable console with modular controllers. It was different from anything Nintendo had made before. The Switch 2 is mostly the same proposition, just nicer.

You won’t feel the same regret for missing out on a whole new way to play this time, since it’s a continuation of the same idea. There are two new features you might envy: audio or video Game Chat among friends and the new Joy-Cons working like mice in some supported games. But Game Chat works only with other Switch 2 owners and needs a Switch Online subscription. The mouse functions are fun at times, but could also end up as just a gimmick. For now, the Switch 2 hasn’t pulled that many wild new functions out of its hat, but that could change, knowing Nintendo. There are also some fun camera-connected party game modes for Mario Party Jamboree if you happen to connect a camera, but no other games even have new camera-based features yet.

It’s fine to wait, but tariffs are still a question mark

I’m saying this well before I’ve had a chance to review the Switch 2, and for sure, it looks like the best Nintendo console in a long while and worth upgrading to. But take some comfort that missing out on getting one early this time isn’t quite as big a deal as it was in 2017, even if you’re feeling the pull of regret. 

The only wild card remains the question of the effect tariffs will have on future console pricing. Will it fluctuate? I hope not, but the prices of Nintendo’s Switch 2 accessories have already gone up as a result of Trump’s chaotic tariff policies, and it’s unclear if that might happen again. The state of pricing and consumer electronics is still in an unknown zone, but in the meantime, you can still have a lot of fun on the Switch you already have, now and even in the near future.

Apple to Shift All US iPhone Assembly to India Amid Tariff Turmoil, Report Says

The manufacturing move aims to address massive US tariffs against China that could spur higher prices on the company’s biggest-selling product.

Apple could be sourcing its entire line of iPhones for the US market — about 60 million devices a year — from assembly facilities in India by the end of 2026, according to a report from the Financial Times

The planned move comes against the backdrop of the Trump administration imposing tariffs against China of up to 145%, although some products such as mobile phones and computers have been exempted for the time being. Apple has long centered its iPhone production in China, making it vulnerable to any trade war between the two countries and spurring speculation that tariffs could mean price increases for the company’s biggest-selling product. 

By moving third-party assembly of US iPhones to India, Apple could avoid the most significant cost pressure of a trade war, though India itself faces new tariffs as well.

The company had already begun shipping iPhones made in India, adding to its product reserves, before new tariffs became active.

A representative for Apple did not immediately respond to a request for comment.
