The best search engine for privacy is the one whose records match what you want kept private. Every search engine has to see your query to answer it, so no engine records nothing. What separates a private search engine from the rest is what it keeps afterward, how long it keeps it, whether it ties your searches to you, and who else receives them.
That gives you a short list to check before you switch: what's stored, for how long, whether searches link to an account or a cookie, whether the results page loads anything from other companies, whether ads are targeted at you, where the results come from, whether an AI feature sends your query somewhere else, and what happens when someone asks the engine for its records. The rest of this guide walks through each one and shows you how to test the claims yourself, because a privacy page tells you what a company says and your browser tells you what it does.
Why does search engine privacy matter?
Search is where people type the things they wouldn't say out loud: symptoms, debts, a lawyer's name, a job they're thinking about leaving. A year of someone's searches says more about them than most things they'd post publicly.
It also matters because most of those searches go to one place. In September 2026, Google handled 89.94% of searches worldwide, according to StatCounter's search engine market share figures. Choosing a different engine is one of the few privacy decisions that changes something every day, with no settings to maintain afterward.
What does a search engine learn when you search?
A search engine learns your query, your IP address, your browser and device, your language, the page that sent you, and which result you clicked. Most of that arrives with every web request whether the engine wants it or not. Privacy depends on what happens to it next.
Here's what a typical search hands over:
The query itself, which is the whole point of the request.
Your IP address, which the server needs to send the answer back, and which maps to a rough location.
Your user agent, a line of text naming your browser, operating system and device type.
Your language, from your browser's settings.
The referrer, the page you came from, when your browser sends it.
Cookies the engine set on an earlier visit, which let it recognize you again.
Your click, if the engine records which result you opened and how long until you came back.
None of that is sinister on its own. An engine needs your query to search and your address to reply. The question is whether it stores those things, joins them together, and keeps them long enough to build a profile.
What should you check before you pick a private search engine?
Check eight things: what it stores, how long, what it links to you, its cookies, third-party scripts, ads, where its results come from, and what its AI features send elsewhere. Most of the answers are on the engine's privacy page, and the rest you can test in your browser in a few minutes.
What it stores. Look for whether the engine keeps your IP address and user agent, or reads them and throws them away. "We don't track you" and "we don't store your IP address" are different promises.
How long it keeps it. A log kept for a day is a different thing from a log kept for years. Look for a number of days, not "as long as necessary."
What it ties to you. If you're signed in to an account the engine runs, your searches may be saved under it. Check whether you can search signed out, and whether a cookie identifies you across visits.
Cookies and consent. A single first-party cookie that expires is a mild thing. Several cookies from other companies are not. Check whether the engine respects Global Privacy Control, a browser signal that, in its own words, is "designed to allow Internet users to notify businesses" that they don't want their personal information sold or shared.
Third-party scripts. A results page that loads analytics, fonts or ads from other companies lets each of those companies see that you searched, even if the engine itself keeps nothing.
Ads. An ad-supported engine can be private, but ask what its ad partner receives. Ads chosen from your query alone reveal less than ads chosen from a profile of you.
Where results come from. Many smaller engines license results from a larger one. That's fine for privacy if the engine forwards only the query, but check the policy for what it sends upstream. The guide to independent search engines explains how to tell who runs the index.
AI features. An AI answer box may send your query, and sometimes the pages it read, to a model provider. Check who runs the model and what they keep. Search engines without AI covers how to turn those features off.
Add a ninth if it matters to you: where the company is based and what it says about legal requests. Every engine answers to the law somewhere, and a good privacy page says when it hands records over.
Is a search engine that doesn't track you the same as one that logs nothing?
No. "Doesn't track you" usually means it doesn't follow you across other sites or build an advertising profile. It doesn't promise the engine keeps no record of your searches. Plenty of engines that don't track you still log queries and addresses to fight spam, abuse and illegal content, and to improve their ranking.
Carpathian Search is a concrete example of the difference. It shows no ads, loads no third-party scripts on its search page, and never sells its records or shares them with advertisers. Its privacy page also says it collects your searches and clicks, your IP address, your browser and device, and an approximate location, and that it ties your searches to your Carpathian account if you're signed in to one in the same browser. That's a reasonable trade if what you want is search without an ad business behind it. If your priority is an engine that keeps no record of your address, it isn't the one to pick.
The useful habit is to read the verbs. "Collect," "store," "retain" and "share" each mean something different, and a privacy page that uses them carefully is easier to trust than one that says "we respect your privacy" and stops.
How do you check a search engine's privacy claims yourself?
Open the results page with your browser's developer tools and look at what it loads and what it stores. You can see every request to another company and every cookie the page sets, which is the part of a privacy policy you can check without trusting anyone.
Open the network panel. In Chrome, Firefox, Edge or Safari, open the developer tools (in Safari, turn on the Develop menu in its settings first) and pick the Network tab. Run a search. Every request goes to the domain it names, and any domain that isn't the engine's own is a company that saw your search.
Check the cookies. In the same tools, the Application tab in Chrome and Edge, or Storage in Firefox and Safari, lists every cookie the page set. Note how many there are, which domains they belong to, and when they expire.
Turn on Global Privacy Control in a browser that supports it and search again. An engine that honors it should set fewer cookies or none.
Read the retention numbers on the privacy page and write them down. If there aren't any, that's an answer too.
Search signed out. If you have an account with the engine's parent company, try a private window and see whether anything changes.
Ten minutes of this tells you more than a ranked list of private search engines can.
What can't a private search engine hide?
A private search engine protects the search, not what happens after it. Once you click a result, the site you visit sees your address and whatever its own scripts collect. Your internet provider, or your DNS resolver, can still see which sites you connect to, and browser extensions can read pages you open.
The site you click sees you as a normal visitor, with its own cookies and trackers.
Your network sees the domains you connect to, even when it can't read the pages.
Your browser may sync history to an account, and extensions can read what's on screen.
Your device keeps its own history unless you clear it or use a private window.
A private search engine is one layer. Pair it with a browser that blocks third-party trackers and a habit of signing out when you don't need to be signed in, and it does far more than it does alone.
Which private search engine fits what you want?
Start from what you're trying to avoid. Pick the engine whose policy covers that, and don't pay for protection you don't need with worse results you'll notice every day.
You want to stop being profiled for ads. Any engine with no ads, or ads chosen from the query alone, and no third-party scripts will do.
You want nothing tied to your identity. Look for no account requirement, a short retention period stated in days, and an engine that discards your IP address. Search in a private window.
Whatever you choose, test it on the searches you run every week. A private search engine you abandon after three days protects nothing.
Try two engines for a week
Pick two engines that pass the checks above, make one your browser's default, and keep the other a tab away for the searches the first one misses. At the end of the week you'll know which one you trust and which one finds what you need. To try one with its own index and no ads, search at https://search.carpathian.ai, and read what it records on its privacy page first.
