Most people pick a notes app the same way they pick a default browser: it came with the phone. Galaxy owners get Samsung Notes. People who live in Google's apps reach for Keep. Then they type passwords, journal entries, and half-finished ideas into it and never think about where any of that goes.
This is a head-to-head on the only question that decides whether a notes app is actually private: who can read your notes besides you. On that question, Samsung Notes and Google Keep land in almost exactly the same place. Here is the detail, and the one thing that genuinely separates them from a private app.
Full disclosure: I built Scrib, an encrypted offline notes app for Android. I have an obvious stake here. I will keep this factual anyway, including where each app is the better tool.
Which Is More Private: The Short Answer
Neither Samsung Notes nor Google Keep is end-to-end encrypted, so on privacy it is a tie at the bottom: both vendors can read your notes. Samsung holds the keys to anything you sync to Samsung Cloud, and Google holds the keys to anything in Keep. Whoever holds the key can decrypt the content. Neither app puts that key in your hands alone. The longer reads on how Samsung Notes handles your data and why Google Keep holds every encryption key walk through the receipts for each app.
That makes the "which is more private" question the wrong fight. The only honest tie-breaker is which account you secure best and which company you distrust least, not which app keeps your notes from the vendor. If the real goal is that nobody but you can read a note, the answer is a third option: an app that holds nothing on a server, like Scrib, which keeps every note encrypted on your device with no account and no cloud.
Here is the privacy comparison stripped to the five rows that decide who can read your notes:
| Privacy question | Samsung Notes | Google Keep | Scrib |
|---|---|---|---|
| End-to-end encrypted? | No | No | Yes, on-device |
| Who holds the key | Samsung | You | |
| Account required | Samsung or Microsoft | None | |
| Works fully offline | Partial (built around sync) | Partial (built around sync) | Yes, always |
| Data collected | Usage data, diagnostics, content in Samsung services | Usage data, diagnostics | Zero |
The Comparison, On the Things That Matter
Sync, search, and handwriting are real features, but they are not what this page is about. This table is built around one idea: who holds the key, and therefore who can read your notes.
| Feature | Samsung Notes | Google Keep | Scrib |
|---|---|---|---|
| Price | Free | Free | Free |
| Default cloud sync | Samsung Cloud (can back up to OneDrive) | Google account | None, on-device only |
| End-to-end encrypted | No | No | Yes, on-device |
| Who holds the keys | Samsung | You | |
| Account required | Samsung or Microsoft | None | |
| Works fully offline | Partial (built around sync) | Partial (built around sync) | Yes, always |
| Note/folder lock | Yes (uses device lock, not separate encryption) | No | Yes |
| PIN lock + hidden vault | No | No | Yes |
| Data collected | Usage data, diagnostics, content in Samsung services | Usage data, diagnostics | Zero |
| Platforms | Samsung Galaxy mainly | Android, iOS, Web | Android |
Read down the "End-to-end encrypted" and "Who holds the keys" rows first. That is the whole argument. Two of these three apps put a copy of your readable notes on a company's servers. One does not.
How Each App Stores and Syncs Your Notes
Samsung Notes is pre-installed on Galaxy phones. When you sign into a Samsung account, it syncs your notes to Samsung Cloud automatically. That is the default: you have to actively opt out, not opt in. If you enable the Microsoft integration, those notes can also back up to OneDrive, which puts a second company in the loop.
Google Keep is built around your Google account from the first note. Everything you write syncs to Google's cloud so it appears on your phone, your tablet, and at keep.google.com in any browser. That cross-device convenience is the entire point of the app, and it is also the reason your notes live on Google's servers.
Both apps encrypt data in transit with HTTPS and encrypt it at rest on the server. That protects against someone sniffing your connection or stealing a raw disk. It does not protect against the company that owns the disk, because the company also owns the keys.
Who Can Read Them: The Key-Holder Point
Here is the distinction that the marketing word "encrypted" hides. Both apps are encrypted. Neither is end-to-end encrypted, and that gap is the entire story.
End-to-end encryption means the key that unlocks your notes exists only on your device. Not even the company running the servers can read your content. Samsung Notes and Google Keep do not work that way. Samsung holds the keys to what you sync to Samsung Cloud. Google holds the keys to what you sync to Keep. In both cases the vendor can decrypt your notes.
That has three practical consequences, identical for both apps:
- The company can technically access your notes. Their privacy policies permit processing content stored in their services to operate and improve them.
- A valid legal request reaches your notes. Because there is a readable copy on a server, both Samsung and Google can be compelled to hand it over.
- A server breach exposes plaintext. If an attacker reaches the keys, the notes are readable, not just scrambled.
So when someone asks whether Samsung Notes is more secure than Google Keep, the honest answer is that they are equivalent on the part that counts. Both put a copy of your notes somewhere you do not control, behind keys you do not hold.
The Real-World Risk That Actually Matters
Forget the "is the vendor evil" debate for a moment. The risk that hits ordinary people is not a Google engineer reading your grocery list. It is your account getting taken over.
Your Google account is a single key to everything Keep has ever synced. Your Samsung account is the same for Samsung Notes. If either account is phished, or its password leaks from an unrelated breach and you reused it, an attacker gets:
- Every note you have ever synced, including ones you deleted from the phone but that still live in the cloud.
- Access from any web browser, with no physical access to your device.
- The ability to read, copy, or export your notes quietly, with no alert on your phone.
Credential-stuffing attacks, where attackers replay username and password pairs leaked from other sites, are one of the most common ways accounts fall. Samsung has also had confirmed breaches in 2019 and 2022, including the theft of source code for Galaxy security systems, which weakens the assumptions the cloud rests on. Google runs a larger and heavily targeted account system. Pick your poison: in both cases your notes are only as safe as one account password and one company's servers.
End-to-end encryption removes this whole category, because there is no readable copy on a server to reach. An app with no account and no cloud removes it even more completely, because there is no server at all.
Which Should You Pick
Here is the honest version, by use case.
If you live in Samsung's ecosystem, sync across your Galaxy devices, use the S Pen, and only put non-sensitive notes in the app, Samsung Notes is the convenient choice. Turn on two-factor authentication for your Samsung account and skip the OneDrive backup if you do not need it.
If you live in Google's ecosystem, want your notes on every device and on the web, and again keep nothing sensitive in them, Google Keep is the convenient choice. Turn on two-factor authentication for your Google account.
Notice the pattern. The tie-breaker between the two is not privacy, because neither is private in the strict sense. It is which account you already secure best and which ecosystem you already use. Choose the one you trust more and protect more carefully.
If the actual goal is that no one but you can read your notes, neither app qualifies, and no settings change fixes that. For passwords specifically, use a dedicated manager like Bitwarden (free, open source, end-to-end encrypted). For private text such as journal entries, medical details, or financial notes, you want encryption where you hold the key.
The On-Device Alternative
I built Scrib for the third case: notes that never leave your phone. Every note is AES-256 encrypted the moment you save it, using a key generated on your device and stored in the Android Keystore, a hardware-backed area other apps cannot reach. There is no account, no email, no sign-up. There is no networking code in the app, so there is no Samsung Cloud, no Google account, and no server to breach.
On top of automatic encryption, you can set a PIN lock for the whole app and move your most sensitive notes into a hidden vault that opens only with your PIN. That is the layer the note-lock feature in Samsung Notes and Google Keep does not give you.
The trade-off is real and worth stating: no cloud sync. Scrib runs on Android only, and if you lose your phone without a manual backup, those notes are gone. That is the honest cost of keeping data off servers entirely. If you need encrypted sync across devices instead, Standard Notes uses end-to-end encryption so even its own servers cannot read your content.
Common Questions
Is Samsung Notes more secure than Google Keep?
Not in any way that protects your note content. Neither app is end-to-end encrypted, so both Samsung and Google hold the keys to the notes you sync. The practical difference is which company and which account you trust less, not whether one of them can read your notes. Both can.
Is Samsung Notes end-to-end encrypted?
No. Samsung Notes data is encrypted in transit and at rest on Samsung's servers, but it is not end-to-end encrypted. Samsung holds the decryption keys, so Samsung can technically access your synced notes. Notes can also be backed up to Microsoft OneDrive, adding a second company with potential access.
Is Google Keep end-to-end encrypted?
No. Google Keep encrypts notes in transit and at rest on Google's servers, but Google holds the encryption keys. That is not end-to-end encryption. End-to-end means only you hold the key, so not even the company running the servers can read your content.
Can Samsung or Google read my notes?
Yes, technically. Because neither Samsung Notes nor Google Keep is end-to-end encrypted, each company holds the keys to the notes you sync and can decrypt them. Both can also be compelled to hand over your notes in response to a valid legal request, and both have privacy policies that permit processing content stored in their services.
Which is more private, Samsung Notes or Google Keep?
Neither is private in the strict sense, because neither is end-to-end encrypted. If you are choosing between the two, pick the ecosystem and account you already trust more and protect best with two-factor authentication. But if the real goal is that no one else can read your notes, neither app meets that bar.
What is the most private alternative to both?
An app that keeps notes on your device with no account and no cloud. Scrib is a free Android notes app that encrypts every note with AES-256 using a key held in the Android Keystore, with no account and no network permissions, so there is no server for anyone to reach. If you need encrypted sync across devices, Standard Notes uses end-to-end encryption so even its own servers cannot read your content.
