Obsidian vs Google Keep: Privacy Comparison
In this comprehensive privacy comparison, we analyze Obsidian and Google Keep across six critical dimensions: data collection practices, encryption implementation, third-party data sharing, user privacy controls, transparency, and historical track record. Both services serve similar needs, but their approaches to user privacy differ significantly. Our analysis reveals that Obsidian offers a meaningfully better privacy experience overall, though each service has relative strengths and weaknesses worth understanding in detail.
Who Wins, and Why
The most useful starting point is the overall tally and the single dimension that decided it. Across the six privacy dimensions we score, Obsidian finishes ahead of Google Keep, 54/60 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.
The largest single-dimension gap is in Data Collection, where Obsidian leads by 3 points -- Obsidian 10/10 to Google Keep 7/10. The tightest race is Encryption, separated by just 2 points (Obsidian 10/10, Google Keep 8/10). Everything below justifies these totals dimension by dimension.
How Each Service Collects Data
The starting point for judging privacy is always how data is collected. The amount of user data a service captures, keeps, and works with is the single biggest factor behind its privacy exposure. Obsidian shows more discipline on this front, collecting nothing beyond the bare minimum needed for the service to run. The competing option reaches for a much wider set of data, including behavioral patterns, device identifiers, and usage analytics that stretch beyond the essentials. In this category we rated Obsidian 10/10 and Google Keep 7/10. The gap comes down to more than raw volume -- it is about the intent behind each piece of data and whether collecting it was ever justified.
Encryption Standards
Whether data is moving or resting, encryption is what keeps it safe, and the quality of that work swings widely across services. Obsidian 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, Obsidian scored 10/10 and Google Keep scored 8/10.
Sharing Data With Outside Parties
A service's willingness to hand data to outside parties is a make-or-break privacy factor. That covers advertising networks, analytics providers, business partners, and what happens when governments come asking. Obsidian keeps a tighter lid on who can reach user data. These sharing habits shape security as much as privacy, since every extra party granted access becomes one more way a breach could happen. Scores: Obsidian 7/10, Google Keep 4/10.
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. Obsidian delivers broader, easier-to-reach privacy controls. Scores: Obsidian 8/10, Google Keep 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. Obsidian 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: Obsidian 9/10, Google Keep 6/10.
Historical Track Record
Looking at how a service has handled privacy incidents, regulatory actions, and disclosed vulnerabilities over time adds essential context. Obsidian 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: Obsidian 10/10, Google Keep 7/10.
Our Bottom-Line Call
Adding everything up, our full analysis lands Obsidian at 54/60 and Google Keep at 37/60. For privacy, the overall winner is Obsidian. 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.
