The 6 best private notes apps for Mac in 2026
“Private” means three different things — encrypted, local, or locked — and most lists blur them. We build one of these apps, so we'll be precise about what each model protects you from, including where ours doesn't.
There are three honest privacy models for notes. End-to-end encryptionscrambles notes before they sync, so even the vendor can't read them. Local-only never sends notes anywhere, so there is nothing to intercept in the first place. Lockingguards notes from people at your keyboard, and says nothing about servers. Every app below is a deliberate mix of these — and the right one depends on whether you're defending against a breach, a business model, or a sibling.
At a glance

| Obsidian | Privacy through ownership | Free; paid sync add-on | Local files; E2EE paid sync |
| Apple Notes | Good-enough privacy, zero effort | Free with your Mac | iCloud sync; lockable notes |
| Locus | Privacy by not participating | Free while in development | Local only — nothing to intercept |
1. Standard Notes
Best for: Maximum-paranoia plain text · Free tier; paid features
The app privacy people recommend to each other. Everything is end-to-end encrypted before it leaves your machine, the code is open source and audited, and the company's whole identity is not being able to read your notes. The free tier is deliberately spartan — plain text, no frills — with editors and themes behind the paid plan. If your threat model is serious, start here.
2. Notesnook
Best for: E2EE without the spartan feel · Free tier; paid Pro
The same zero-knowledge promise as Standard Notes with a warmer, more full-featured editor out of the box. Open source, encrypted by default, sync included. The trade for all that encryption is format: your notes live in an encrypted store, not files you can open with other tools, so leaving means exporting.
3. Joplin
Best for: Encrypted sync on your own terms · Free; paid hosted sync
Open source and flexible about where your notes go: keep them local, or sync end-to-end encrypted through Joplin Cloud, Nextcloud, or storage you control. That flexibility is the appeal and the chore — you're the one configuring it. The Electron interface is workmanlike rather than lovely, but the privacy engineering underneath is sound.
4. Obsidian
Best for: Privacy through ownership · Free; paid sync add-on
A different privacy philosophy: nothing leaves your Mac because nothing is sent anywhere. Your notes are plain Markdown files, as private as your disk is — which means FileVault and your login password are doing the guarding, not the app. Optional paid sync is end-to-end encrypted. The cost is Obsidian's usual one: setup, plugins, and raw Markdown as the daily experience.
5. Apple Notes
Best for: Good-enough privacy, zero effort · Free with your Mac
Better than its reputation. Individual notes can be locked behind your password or Touch ID, and iCloud data is encrypted in transit and at rest — with full end-to-end protection if you turn on Advanced Data Protection. The caveats: notes sync to Apple's cloud by default, locking is per-note housekeeping you have to remember, and your notes live in a database only Apple's tools read well.
6. Locus
Best for: Privacy by not participating · Free while in development
Ours — judge accordingly. Locus's privacy model is structural rather than cryptographic: there is no account, no sync, no analytics, and no path that uploads a note, so there is nothing to intercept and no server to subpoena. App Lock adds Touch ID before the app opens — access control, not encryption; encryption at rest is FileVault's job, and we say that plainly. Your workspace is readable files on your own disk. The full reasoning is in our private notes page.
How we chose
We make Locus, so the tests are ones that don't bend our way: is the privacy claim structural (encryption, or no network path) rather than a policy promise; is the code or the file format inspectable; does privacy survive the free tier; and is the app honest about what it doesn't protect. That last one matters most — an app that names its limits is safer to trust than one that says “military-grade” and hopes you stop reading. For the practical side — turning off sync, locking the screen layer, FileVault — see how to make your notes private, and if the lock itself is what you need, see notes apps with a password.
Questions people ask
Which notes app is most private?+
Define the threat first. Against a stolen or shared laptop, anything with a lock helps — locked Apple Notes, App Lock in Locus, any encrypted app. Against a subpoena or a breach of the vendor, end-to-end encryption is the bar: Standard Notes and Notesnook are built for exactly that. Against quiet telemetry and training-data harvesting, local-only apps win by having no pipe at all — Obsidian and Locus never send your notes anywhere.
Is there an encrypted place for notes on a Mac?+
Yes, several honest answers: Standard Notes and Notesnook encrypt end-to-end before anything syncs; Apple Notes can lock individual notes and gains end-to-end iCloud encryption under Advanced Data Protection; and every file on your Mac — including local notes from Obsidian or Locus — is encrypted at rest once FileVault is on, which it should be regardless of your notes app.
Do private notes apps need the cloud?+
No — that's a choice, and it's the main fork in this list. E2EE apps use the cloud but make it unreadable to everyone but you, buying multi-device sync. Local-only apps skip the cloud entirely, buying simplicity and a smaller attack surface at the cost of living on one machine. Neither is wrong; they protect against different things.
Is Apple Notes private enough?+
For most people, mostly. Locked notes and Advanced Data Protection close the biggest gaps. The honest limits: sync to iCloud is the default you have to opt out of, locking is manual per note, and your notes live in a database rather than files you can inspect or back up on your own terms. If any of those bother you, that's what the rest of this list is for.
