What makes a search engine "private" exactly?
Private search engines are designed to give you results without collecting your personal data. But privacy isn't a single switch: it’s a combination of technical and policy choices. Here's what the most private search engines usually have in common:
- No logging: They don’t store your IP address, search queries, or browser fingerprint
- Open-source code: Some engines allow anyone to inspect how they work
- No third-party ads: This eliminates scripts and pixels which can be used to track your activity
- Decentralized or self-hosted options: Some engines allow you to run your own version
- Jurisdictional advantage: Servers located in countries with strong digital privacy protections
If your search engine doesn’t meet these standards, it’s likely leaking a lot more data than you think.
Want to know what really exposes your identity online? It’s not just cookies: it’s metadata. That includes your IP address, time of connection, and device fingerprint, all of which can be logged even if the search engine says it doesn’t track you.
Comparing the most private search engines
To help you choose the best option, here’s a breakdown of top private search engines, how they store data, and where they’re hosted.
Each of these search engines has strengths and trade-offs. For example, Startpage provides Google-level results without trackers, while YaCy is fully decentralized. So choose based on how much control and anonymity you need.
Can you trust private search engines?
Using a private search engine is a big privacy win — but it doesn’t make you invisible. Most private engines don’t track your searches, but they also don’t mask your IP, protect you from DNS leaks, or hide your traffic metadata.
That’s why pairing a search engine with a privacy-first VPN is essential. It’s the difference between clearing your tracks and never leaving any to begin with.
How to set a private search engine as default
So you’ve picked your private search engine. Now make sure it’s the one your browser uses by default. Here’s how to update it quickly.
You should also review other browser settings to limit fingerprinting and telemetry.
Open source vs. closed source: Why it matters
Transparency is a key part of trust in any privacy tool. Open-source search engines allow anyone to inspect the code, identify vulnerabilities, and verify claims about how data is handled.
Closed-source alternatives, by contrast, require blind trust: you can’t see how the code handles your data behind the scenes. For those who want full transparency, open-source engines like SearXNG and YaCy stand out to the Nym team.

Build a privacy stack with a VPN
Even if a search engine doesn’t track your activity, metadata like your IP address can still reveal who you are and what you're doing online. A Virtual Private Network (VPN) works alongside private search engines to hide your network location, encrypt your connection, and prevent surveillance by ISPs or third parties.
For truly anonymous search, you need both a VPN designed for privacy and a private browser
Unfortunately, with most VPNs your IP is hidden, but metadata can still leak. That’s why we built NymVPN, to be more than a VPN.
Why add NymVPN?
NymVPN isn’t a typical VPN. It’s built on a decentralized mixnet that routes your traffic through multiple servers, mixing it with other people’s traffic and cover traffic. This prevents any observer — even at the network level — from knowing who you are, what you’re doing, or when.
If you care about anonymity beyond the browser, NymVPN is the privacy layer your search engine is missing:
- Hides your IP address from search engines and ISPs
- Prevents DNS and metadata leaks
- Resists censorship through VPN targeting
- No logging, because NymVPN can’t log.
Together with a private search engine, NymVPN helps you stay anonymous, even on a hostile internet.
Many rely on affiliate links, donations, or paid partnerships with privacy-friendly organizations. For example, Startpage shows non-tracking ads, and SearXNG can be run without any monetization.
