Journal Lock protects entries when someone else has access to your unlocked device.
Turning the lock on
Settings ▸ Privacy ▸ Journal Lock enables Face ID, Touch ID or your device authentication. Echo uses the system authentication. It never stores or sees your passcode or biometrics.
Auto-lock
Settings ▸ Privacy ▸ Auto-Lock decides how long Echo stays open before it locks itself again. A shorter timeout reduces how long the journal remains accessible after authentication.
On Mac, Settings ▸ Privacy ▸ Lock on App Switch locks Echo the moment you move to another app.
The privacy screen
While the journal is locked, Echo blanks its own window in the app switcher, so your last entry is not sitting there in the multitasking preview. This happens automatically.
Journal lock and entry locks
The journal-wide lock gates the writing area. New Entry also asks you to unlock first, so using the plus button or a keyboard shortcut does not bypass it. Cancelling authentication leaves the journal locked.
Individual entries can be locked separately. The padlock menu offers Unlock All Locked Entries for the current session and Re-lock All Entries afterwards. Lock Journal Now closes the whole journal when Journal Lock is enabled. Revealing entries for a session is different from removing their individual lock setting.
Clipboard
Settings ▸ Privacy ▸ Clipboard Access governs whether Echo reads from or writes to the clipboard. Tighten it if you use a clipboard manager that keeps history.
