Notes Tech: 100% local Markdown note-taking, encrypted at rest. Written in Kotlin.

Radical privacy
• No INTERNET permission — verifiable with aapt dump permissions app.apk
• No account, no telemetry, no tracker, no advertising
• SQLCipher AES-256 database, key sealed by the Android Keystore
• Multi-step panic mode: wipes keys, database and dictation model in seconds
• Optional app lock: a PIN, plus strong biometrics if you wish

Per-folder vaults
• Argon2id passphrase (m=64MB, t=3) or Keystore-bound PIN (Android 9+)
• AES-256-GCM per note, bound to its note (anti-swap)
• PIN auto-wipe after 5 failures
• Configurable auto-lock (5 min to never)

On-device voice dictation
• whisper.cpp built into the app; Whisper model imported manually
• SHA-256 verified at import and before loading
• Recordings deleted after transcription

Editing
• Notes open to be read (Markdown: headings, lists, links); “Edit” to write, autosave
• Long press on a note: edit, move to trash with Undo, or delete permanently
• A pastel colour per note in the lists (a vault note's only while its vault is open)
• [[Title]] backlinks with autocomplete + "notes linking here" panel
• Instant FTS5 search, find in note with highlighted matches, configurable sort
• Markdown export, one note or a ZIP (YAML frontmatter, Obsidian/Logseq compatible)
• Import of Markdown, text and ZIP files; share text or files from other apps
• Encrypted backup of your notes and vaults, restored without overwriting anything

Five languages
• English, French, German, Italian, Spanish — chosen in Settings
• Light / dark / system theme
• Privacy policy and terms in the five languages

Permissions
• Microphone: dictation only, asked when you turn it on
• Biometrics: app lock only, gives access to no data
