Secure Notes Apps That Sync With iCloud (2026): What Is Really Encrypted
Which secure note apps sync with iCloud in 2026, what iCloud encrypts by default, what Advanced Data Protection really covers, and how to choose the right app.
Quick answer:Apple Notes, Bear and Secure Notes all sync through iCloud. Apple Notes locked notes and Bear's encrypted notes are end-to-end encrypted by default, and Advanced Data Protection extends that to every Apple Note. Secure Notes sync is not end-to-end encrypted: it uses Apple's standard iCloud encryption. Pick by threat: encryption on Apple's side, or locks on your phone.
Is iCloud sync the same as end-to-end encryption?
No. iCloud sync is convenience: notes appear on every device signed in to your Apple Account. End-to-end encryption is privacy: only your devices hold the keys, so even Apple cannot read the data. An app can sync through iCloud without being end-to-end encrypted, and most do.
By default, iCloud encrypts data in transit and on Apple's servers, with Apple holding the keys for most categories. Advanced Data Protection moves those keys to your devices for Notes, iCloud Backup, Photos, iCloud Drive and more. For third-party apps, it covers data in iCloud Backup and CloudKit encrypted fields and assets. Apple lists exactly what is covered in its iCloud data security overview.
Which apps sync with iCloud, and what is encrypted?
| App | iCloud sync | End-to-end encryption | Locking |
|---|---|---|---|
| Apple Notes | Yes, free | Locked notes always; all notes with Advanced Data Protection | Single notes, one shared password or device passcode |
| Bear | Yes, Bear Pro | Encrypted notes (Pro); other notes use standard iCloud encryption | App lock and encrypted notes (Pro) |
| Secure Notes | Yes, Pro, your private CloudKit database | No (no app-level note encryption; standard iCloud encryption) | App, folder and note locks, decoy PIN (Pro) |
| Standard Notes | No, own end-to-end encrypted sync | Yes, every note, every platform | App passcode and biometrics, protected notes |
| Notesnook | No, own end-to-end encrypted sync | Yes, every note, every platform | App lock and a password vault |
How does Secure Notes sync with iCloud?
Secure Notes Pro syncs through your own private iCloud database (CloudKit), signed in with your Apple Account. PixelPort has no server that stores or reads your notes. The app does not add its own encryption before sync, so iCloud copies have Apple's standard iCloud encryption, with Apple holding the keys. It is not end-to-end encrypted.
What Secure Notes adds on each device is the lock: the app opens only with your passcode, Face ID or Touch ID, folders and single notes can have their own lock, a decoy PIN (Pro) opens a harmless notebook, and the app can hide from the app switcher (Pro). For an offline copy, Pro (version 3.8.1 and later) exports a password-encrypted AES-256-GCM backup file. Read the full model on our security page.
What about Apple Notes?
Apple Notes is the strongest default here: locked notes are end-to-end encrypted with your notes password or device passcode, and turning on Advanced Data Protection extends that to every note. The limits are about access: one shared password, no folder locks and no decoy. Full details in is Apple Notes end-to-end encrypted.
Do I need Advanced Data Protection?
If you keep sensitive notes in any iCloud-synced app, turning on Advanced Data Protection is the single biggest upgrade: it makes most iCloud data, including Apple Notes, end-to-end encrypted. For third-party apps it covers only CloudKit encrypted fields, so check each app. You must keep a recovery key or recovery contact, because Apple can no longer help you recover.
Our Advanced Data Protection guide walks through it step by step.
The right setup in 2026
Turn on Advanced Data Protection. Keep everyday notes in Apple Notes. Put the notes you want behind a separate lock, with a decoy PIN for pressure situations, in Secure Notes. If you need end-to-end encrypted sync to Windows, Linux or Android, Standard Notes or Notesnook use their own encrypted sync instead of iCloud. Bear also syncs through iCloud; see Secure Notes vs Bear and Bear alternatives, or the wider list of Apple Notes alternatives.
