Ungoogled Chromium vs Chrome: Privacy Comparison
Here we put Ungoogled Chromium head-to-head with Chrome across the six privacy factors that matter most: their data collection practices, encryption implementation, third-party data sharing, user privacy controls, transparency, and historical track record. While both products address similar requirements, the philosophies they bring to protecting users diverge sharply. Our assessment finds that Ungoogled Chromium provides a noticeably better overall privacy experience, although neither service is without trade-offs that deserve a careful, detailed look.
The Result, Up Front
The most useful starting point is the overall tally and the single dimension that decided it. Across the six privacy dimensions we score, Ungoogled Chromium finishes ahead of Chrome, 43/60 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.
Data Collection produced the widest separation between the two, with Ungoogled Chromium ahead 8 to 7 out of 10. The tightest race is Data Collection, separated by just 1 point (Ungoogled Chromium 8/10, Chrome 7/10). Everything below justifies these totals dimension by dimension.
What Gets Collected
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. Ungoogled Chromium 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 Ungoogled Chromium 8/10 and Chrome 7/10 in this category. The difference reflects not just the volume of data collected but the purpose and necessity of that collection.
Encryption Implementation
Whether data is moving or resting, encryption is what keeps it safe, and the quality of that work swings widely across services. Ungoogled Chromium brings more capable encryption to the table, pairing more resilient protocols for data in transit with better protection for data at rest. Where the two differ is in coverage (exactly which data is encrypted), in strength (the algorithms and key lengths chosen), and in whether end-to-end encryption is used at all (which stops even the service operator from seeing user content). On encryption, Ungoogled Chromium scored 9/10 and Chrome scored 8/10.
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. Ungoogled Chromium 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: Ungoogled Chromium 5/10, Chrome 4/10.
What You Can Manage Yourself
Individuals only hold real power over their data when a service's privacy controls are available and genuinely effective. The relevant tools include the option to opt out of data collection, ways to download and erase data, granular permission settings, and how readily users can exercise the rights afforded them by applicable privacy regulations. Ungoogled Chromium offers more complete and approachable privacy controls. Scores: Ungoogled Chromium 6/10, Chrome 5/10.
How Clearly They Explain Themselves
Transparency encompasses how clearly each service communicates its data practices. This includes the readability of privacy policies, the publication of transparency reports, responsiveness to privacy inquiries, and proactive communication about policy changes. Ungoogled Chromium demonstrates stronger transparency overall. Clear, accessible privacy communication is essential for informed consent and trust. Scores: Ungoogled Chromium 7/10, Chrome 6/10.
What Their History Reveals
The record of privacy incidents, regulatory run-ins, and how a service answers vulnerabilities offers context you cannot ignore. Ungoogled Chromium holds the stronger track record here, with a smaller count of incidents and a more responsible response to the problems that did surface. More often than not, what a service did in the past is the best guide to its future privacy conduct. Scores: Ungoogled Chromium 8/10, Chrome 7/10.
The Final Verdict
When the full analysis is tallied, Ungoogled Chromium finishes at 43/60 and Chrome at 37/60. On privacy grounds, the overall winner is Ungoogled Chromium. Both products meet similar functional needs, yet the winner brings a more privacy-respecting approach to the dimensions that carry the most weight. Still, perfection is off the table for any service, so no matter which you choose you should actively set up its privacy options. Our advice is to round out your pick with additional privacy tools, a VPN, DNS-level ad blocker, and privacy-focused browser, to assemble a thorough privacy posture. Should your threat model call for the strongest privacy possible, weigh whether an even more privacy-focused alternative exists in this category beyond the two compared here.
