Most popular notes apps. Google Keep, Samsung Notes, OneNote, sync everything to the cloud. That's fine if you want cross-device access. But if you want your notes to stay private and on your device, your options are thinner than you'd expect.
I tested the best private, offline-friendly notes apps available on Android in 2026. Here's the honest breakdown. What each does well, where each falls short, and who each one is best for.
Full disclosure: I built Scrib, the first app on this list. But every app here earned its spot. I'm listing real trade-offs for all of them, including mine.
What I Looked For
- Encryption: Does the app encrypt notes at rest on your device?
- Offline-first: Can it work fully without internet?
- No account required: Can you use it without signing up?
- No tracking: Does it collect usage data?
- Free tier: Is it genuinely usable without paying?
Who Holds the Keys? Checked September 3, 2026
Feature grids tell you what an app promises. The columns below tell you what the code does. Two of the four apps ship without the Android INTERNET permission (Scrib and Notally), one encrypts every note by default (Scrib), one encrypts only after you switch it on (Joplin), and one needs an account to sync (Standard Notes). I checked each app's own manifest and documentation on September 3, 2026; the sources are under the table.
| App | Who holds the key | Network | Account | Export |
|---|---|---|---|---|
| Scrib | You (on-device key, Android Keystore) | No INTERNET permission | None | TXT, unencrypted |
| Standard Notes | You (derived from your password) | INTERNET, for sync | Required for sync | Backup file, encrypted or decrypted |
| Joplin | You, after you enable E2EE (off by default) | INTERNET, for sync | None locally | JEX, Markdown, HTML, PDF |
| Notally | Nobody (unencrypted) | No INTERNET permission | None | TXT, JSON, HTML, PDF |
Key holder means who can decrypt the stored notes. Scrib generates its AES-256 key on the phone and keeps it in the Android Keystore; no copy exists anywhere else. Standard Notes derives its keys from your account password on your device (Argon2id, then XChaCha20-Poly1305), and its server stores ciphertext. Joplin encrypts only after you switch end-to-end encryption on; until then, notes reach your sync service in the clear. Notally stores notes unencrypted.
Network means the Android INTERNET permission in each app's manifest. Scrib's 3.1.1 release manifest and Notally's manifest do not declare it, so neither app can open a connection. Joplin and Standard Notes need it for sync. Export is how you get notes out: Scrib writes plain-text TXT for one note or all notes to any folder or app you pick, and that file is not encrypted. Notally also runs an automatic backup to a folder you choose. Joplin adds a raw directory export. Standard Notes offers its backup file encrypted or decrypted.
Sources, all read on September 3, 2026: Scrib's 3.1.1 release manifest (I built it) and its Play listing, whose Data safety section reports no data collected; Notally's manifest and README; Joplin's Android manifest, encryption guide, and export guide; Standard Notes' Android manifest and encryption specification, plus its offline help article.
1. Scrib
Best for: Encryption + simplicity. Zero setup privacy.
- AES-256 encryption on every note automatically, plus optional per-note encryption as a second layer
- Encryption key stored in the Android Keystore (hardware-backed)
- 100% offline. No server, no networking code in the app
- No account, no email, no sign-up
- PIN lock + Private Vault for sensitive notes
- Folders, checklists, and note import from Google Keep, Simplenote, Evernote, or text files
- 44 note colors, dark mode, voice input, 10 languages
- Zero data collected. Free, no ads
Trade-offs: Android only. No cloud sync. No collaboration. No web access. If you lose your phone, your notes are gone, that's the trade-off of true offline-only storage.
2. Standard Notes
Best for: Cross-platform encrypted notes with sync.
- End-to-end encrypted
- Available on Android, iOS, Windows, Mac, Linux, and web
- Free tier with basic plain text editor
- Paid tier ($90/year) unlocks rich text, Markdown, spreadsheets, and more editors
- Open source
- Account required for sync
Trade-offs: Needs an account and email to sync. The free editor is plain text only. Advanced editors are behind the paywall. More complex than a simple notepad. But if you need encrypted sync across every platform, Standard Notes is the established option.
3. Joplin
Best for: Markdown power users who want full control.
- Open source
- Optional end-to-end encryption
- Sync via Nextcloud, Dropbox, OneDrive, or self-hosted server
- Rich Markdown editor with plugins and extensions
- Notebook organization, tags, to-do lists
- Free
Trade-offs: Encryption is optional. Not enabled by default. You have to set it up yourself. Sync requires configuring a cloud service or hosting your own server. Steeper learning curve than a simple notes app. But if you're technical and want maximum flexibility, Joplin delivers.
4. Notally
Best for: Clean, minimal, open-source notepad.
- Simple and lightweight
- Offline-first. No cloud features
- Open source (available on F-Droid and Play Store)
- Material Design with dark mode
- Labels, pinned notes, lists
- Free, no ads
Trade-offs: No encryption. No PIN lock. No vault. Privacy comes purely from being offline, your notes aren't encrypted on the device. If someone accesses your phone's file system, your notes are readable. But if you just want a clean, fast, no-nonsense notepad without cloud sync, Notally is solid.
Best Offline Notes App for Android
Scrib is the best offline notes app for Android. It ships with no networking code and asks for no network permission, so notes physically cannot leave your phone. It runs with the connection off, on a plane, or in airplane mode, and every note is AES-256 encrypted on disk by default. Notally is the runner-up if you want offline without encryption.
"Offline" gets used loosely, so here is the distinction that matters. Notally is offline-first but stores notes in plain text. Joplin runs offline yet can sync to Dropbox or Nextcloud the moment you turn it on. Scrib has no sync code at all: there is nothing to switch off, no account, and no telemetry. Google Keep and Samsung Notes only cache for offline use; their core features expect a server. If your test is "does this app ever talk to the internet," Scrib and Notally both answer no by design; only Scrib also encrypts what it stores.
| App | End-to-end encrypted? | Account required? | Works offline? | Open source? | Price |
|---|---|---|---|---|---|
| Scrib | Yes (AES-256, auto) | No | Yes (no network code) | No | Free |
| Standard Notes | Yes | For sync | Yes (sync needs an account) | Yes | Free tier, $90/year paid |
| Joplin | Optional | No | Yes (optional sync) | Yes | Free |
| Notally | No | No | Yes | Yes | Free |
Quick Comparison
| Feature | Scrib | Standard Notes | Joplin | Notally |
|---|---|---|---|---|
| Encryption at rest | AES-256 (auto) | End-to-end | Optional | No |
| Offline-first | Yes (no server) | Yes (sync needs an account) | Optional sync | Yes |
| Account required | No | For sync | No | No |
| Data collected | Zero | Minimal | None | None |
| Free | Yes | Freemium | Yes | Yes |
| Platforms | Android | All | All | Android |
| Open source | No | Yes | Yes | Yes |
| App lock | PIN + vault | Passcode + biometric | Biometric | No |
Password Protected Notes App for Android
A lock and encryption answer different questions. A lock stops the person holding your unlocked phone. Encryption protects the file itself when the phone is lost, imaged, or backed up. Here is who offers which, as of September 2026.
- Scrib: app-wide PIN lock, plus a Private Vault that hides notes from the main list behind the same PIN. Every note is AES-256 encrypted underneath, so the lock is the second layer, not the only one.
- Standard Notes: passcode lock with biometric unlock on Android, on top of end-to-end encryption.
- Joplin: biometric app lock on Android. Encryption is separate and stays off until you enable it.
- Notally: no lock and no encryption. Your phone's screen lock is the only barrier.
Google Keep has no note lock at all. The workarounds that exist are in Can You Password Protect Google Keep Notes?
Most Secure Notes App for Android
"Most secure" depends on the threat. Three checks settle it: who holds the key, whether the app can reach the network, and whether it locks. Scrib passes all three with no account: encrypted by default, no INTERNET permission, PIN lock and vault. Standard Notes passes all three with an account and is the only one here that also encrypts sync end to end. Joplin passes once you enable encryption. Notally passes only the network check.
The trade is the same every time: no network means no sync and no cloud backup. If a lost phone must not mean lost notes, choose Standard Notes and accept the account. If your notes must never leave the phone, choose Scrib and export a TXT backup on your own schedule.
Bottom Line
If you want the simplest encrypted notes app with zero setup, Scrib encrypts everything automatically and never touches the internet.
If you need cross-platform sync with end-to-end encryption, Standard Notes is the established choice.
If you're a Markdown power user who wants full control, Joplin gives you maximum flexibility.
If you want a clean, minimal open-source notepad, Notally is fast and simple.
All four are better options than storing sensitive notes in an unencrypted cloud app. Pick the one that fits how you work.
Common Questions
What is the best private notes app for Android?
It depends on whether you need sync. Without sync, Scrib encrypts every note with AES-256 by default, keeps the key in the Android Keystore, has no INTERNET permission, and needs no account. With sync, Standard Notes is end-to-end encrypted across platforms and requires an account. Joplin fits if you will turn on its optional encryption yourself.
Are there notes apps for Android that don't require an account?
Yes. Scrib, Joplin, and Notally all work without creating an account. Standard Notes requires one for sync. Of the three account-free apps, Scrib is the only one that encrypts every note automatically.
What is the best offline notes app for Android?
Scrib and Notally both run with no internet connection, and neither declares the Android INTERNET permission. Scrib also encrypts every note; Notally stores notes in the clear. Joplin runs offline but syncs to a cloud service once you set one up. Google Keep and Samsung Notes only cache for offline use and expect a server for their core features.
Is there a free encrypted notes app for Android?
Yes. Scrib is free with AES-256 encryption, no ads, and no tracking. Joplin is free and open source with optional encryption. Standard Notes has a free tier with a basic plain-text editor.
Is Scrib safe?
Yes. Scrib encrypts every note with AES-256 and keeps the key in the Android Keystore, a hardware-backed area other apps cannot read. It has no INTERNET permission, so notes never leave your device, and it collects no data. You can add a PIN lock and move sensitive notes into a Private Vault.
What is the most secure notes app for Android?
By the three checks on this page (who holds the key, network permission, app lock), Scrib passes all three without an account: every note encrypted by default, no INTERNET permission, PIN lock and vault. Standard Notes passes all three with an account and adds end-to-end encrypted sync. The right choice depends on whether you need sync.
