Mullvad Browser vs Chrome: Privacy Comparison
This in-depth comparison weighs Mullvad Browser against Chrome 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 Mullvad Browser delivers a clearly stronger privacy experience on balance, even though each option has its own relative pluses and minuses that are worth examining closely.
The Headline Finding
The most useful starting point is the overall tally and the single dimension that decided it. Across the six privacy dimensions we score, Mullvad Browser finishes ahead of Chrome, 47/60 to 35/60. 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.
Data Collection produced the widest separation between the two, with Mullvad Browser ahead 7 to 5 out of 10. On Data Collection the margin nearly vanishes: Mullvad Browser 7/10 against Chrome 5/10. 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. Mullvad Browser 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 Mullvad Browser 7/10 and Chrome 5/10 in this category. The difference reflects not just the volume of data collected but the purpose and necessity of that collection.
How Strong Is the Encryption
Encryption protects user data both in transit and at rest, and the implementation quality varies dramatically between services. Mullvad Browser 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). Mullvad Browser scored 8/10 while Chrome scored 6/10 for encryption.
Sharing Data With Outside Parties
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. Mullvad Browser 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: Mullvad Browser 9/10, Chrome 7/10.
Controls You Can Actually Use
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. Mullvad Browser delivers broader, easier-to-reach privacy controls. Scores: Mullvad Browser 10/10, Chrome 8/10.
Transparency
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. Mullvad Browser 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: Mullvad Browser 6/10, Chrome 4/10.
What Their History Reveals
Looking at how a service has handled privacy incidents, regulatory actions, and disclosed vulnerabilities over time adds essential context. Mullvad Browser carries the better historical record on privacy, having faced fewer incidents and dealt with the ones that did come up more responsibly. How a company has acted before is usually the clearest signal of how it will act on privacy going forward. Scores: Mullvad Browser 7/10, Chrome 5/10.
Our Bottom-Line Call
Our comprehensive analysis gives Mullvad Browser a total score of 47/60 and Chrome a total score of 35/60. The overall winner for privacy is Mullvad Browser. While both services serve similar functional needs, the winner demonstrates a more privacy-respecting approach across the dimensions that matter most. That said, no service is perfect, and users should always configure privacy settings actively regardless of which option they choose. We recommend supplementing your choice with additional privacy tools, a VPN, DNS-level ad blocker, and privacy-focused browser, to build a comprehensive privacy posture. If your threat model requires the strongest possible privacy, consider whether an even more privacy-focused alternative exists in this category beyond the two compared here.
