Kagi vs Brave Search: Privacy Comparison
This in-depth comparison weighs Kagi against Brave Search along six decisive privacy dimensions: how data is collected, how encryption is implemented, how data is shared with third parties, what privacy controls users get, how transparent each service is, and what their historical track record looks like. The two cover much the same ground, yet they handle user privacy in very different ways. What our review shows is that Kagi delivers a clearly stronger privacy experience on balance, even though each option has its own relative pluses and minuses that are worth examining closely.
Reading the Scorecard
The most useful starting point is the overall tally and the single dimension that decided it. Across the six privacy dimensions we score, Kagi finishes ahead of Brave Search, 49/60 to 37/60. That total reflects a side-by-side review in which one service is consistently the more privacy-respecting choice, even though both cover the same functional ground.
Most of the distance between these services opens up on Data Collection: Kagi 9/10 versus Brave Search 7/10. The tightest race is Data Collection, separated by just 2 points (Kagi 9/10, Brave Search 7/10). The deeper analysis that follows shows how the lead was built.
How Each Service Collects Data
Data collection is the foundation of any privacy assessment. The extent to which a service collects, retains, and processes user data directly determines the privacy risks associated with its use. Kagi demonstrates more restrained data collection practices, gathering only the minimum data necessary for service functionality. The other service collects a broader range of data including behavioral patterns, device identifiers, and usage analytics that extend beyond core service requirements. We scored Kagi 9/10 and Brave Search 7/10 in this category. The difference reflects not just the volume of data collected but the purpose and necessity of that collection.
Encryption Standards
Encryption protects user data both in transit and at rest, and the implementation quality varies dramatically between services. Kagi implements stronger encryption measures, including more robust protocols for data in transit and better protection for stored data. The specific encryption implementations differ in their coverage (which data is encrypted), their strength (which algorithms and key lengths are used), and whether end-to-end encryption is employed (preventing even the service provider from accessing user content). Kagi scored 10/10 while Brave Search scored 8/10 for encryption.
Third-Party Data Sharing
How services share data with third parties is a critical privacy dimension. This includes sharing with advertising networks, analytics providers, business partners, and in response to government requests. Kagi maintains more restrictive policies regarding third-party data access. The data sharing practices affect not just privacy but also the security of user information, as each additional party with access represents a potential breach vector. Scores: Kagi 6/10, Brave Search 4/10.
User Privacy Controls
How much say people have over their own data depends on whether the privacy controls a service offers are both present and actually useful. That spans opt-out switches for data collection, the ability to download and delete information, fine-grained permission settings, and how simply users can act on the rights granted to them under relevant privacy regulations. Kagi delivers broader, easier-to-reach privacy controls. Scores: Kagi 7/10, Brave Search 5/10.
How Clearly They Explain Themselves
Transparency comes down to how plainly a service explains what it does with data. It shows up in how readable the privacy policy is, whether transparency reports are published, how quickly privacy questions get answered, and whether policy changes are communicated up front. Kagi comes across as the more transparent of the two overall. Plain, easy-to-find privacy communication is the bedrock of informed consent and trust. Scores: Kagi 8/10, Brave Search 6/10.
What Their History Reveals
A service's history of privacy incidents, regulatory actions, and responses to vulnerabilities provides important context. Kagi has a stronger historical record on privacy, with fewer incidents and more responsible handling of the issues that have arisen. Past behavior is often the best predictor of future privacy practices. Scores: Kagi 9/10, Brave Search 7/10.
The Final Verdict
Adding everything up, our full analysis lands Kagi at 49/60 and Brave Search at 37/60. For privacy, the overall winner is Kagi. The two cover much the same functional ground, but the winner takes a more privacy-respecting stance across the dimensions that count for the most. Even so, no service is flawless, and whichever option you pick, you should always tune its privacy settings deliberately. We suggest pairing your choice with extra privacy tools, a VPN, DNS-level ad blocker, and privacy-focused browser, so you end up with a well-rounded privacy posture. And if your threat model demands the very highest level of privacy, it is worth asking whether an even more privacy-focused alternative exists in this category beyond the two compared here.
