CypherLeaf
Private, offline notes with folders, tags, and a lock for sensitive entries.
新版本 1.1.0
Automatic backups: choose daily or weekly and a folder in Settings, and CypherLeaf saves an encrypted backup there whenever one is due.
Attachments now open inside the app: images, text files and PDFs.
Fixes: the green note colour can be picked again, and with App lock on, choosing a file or folder no longer locks the app and loses your place.

CypherLeaf is a clean, private note-taking app for Android. It works fully
offline, has no ads, no trackers, and no account. Your notes stay on your
device.
Features:
* Notes with folders and tags to keep things organised
* Pin important notes to the top
* Trash with restore, so a delete is never final by accident
* App lock using your device biometric or screen lock
* Protected notes: individual notes and their attachments are encrypted with
AES-GCM, and the key is held in the Android Keystore, separate from the
notes database
* Attachments on notes
* Reminders with notifications
* A home-screen widget for recent and pinned notes
* Export notes as plain text, Markdown, or JSON
* Encrypted portable backup protected by a passphrase (PBKDF2 + AES-GCM),
so you can move your notes to a new device safely
* Light and dark themes, with an adjustable font size
Privacy:
CypherLeaf requests no internet permission in its release build, so it
cannot send your notes anywhere. Fonts are bundled with the app rather
than downloaded. Protected notes and encrypted backups never leave the
device in readable form.
Only notes you mark as protected are encrypted. Other notes are kept in the
app's private storage, which other apps cannot read, but they are not
encrypted by CypherLeaf. Android's own cloud backup and phone-to-phone
transfer are switched off, so nothing is copied off the device unless you
export it; use the encrypted backup to move to a new phone.

新版本 1.0.1
Fixes from the F-Droid review of 1.0.0.
A reminder set while notification permission is denied now explains that it
will not appear, instead of silently staying unset. Screenshots are blocked
only while a protected note is open, not everywhere in the app.
Also an accessibility pass: better contrast on buttons and note badges,
screen-reader labels for trash actions, a live search result count, and
heading navigation. Database failures are now reported instead of ignored.
