About Notes Tech
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

• 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

| Release info | Update on Oct 31, 2026 |
|---|---|
| Release notes | Notes Tech 3.2.2 is a security fix. Your notes, folders and vaults are kept. Before you update • Installed from F-Droid? Wait for F-Droid. F-Droid builds and signs Notes Tech with its own key, so these APKs cannot update an F-Droid install; 3.2.2 reaches F-Droid a few days after this release, once F-Droid has built it. • Installed from GitHub? Any APK below updates 3.2.1, 3.2.0, 3.1.x, 3.0.0 or a 2.0.x in place. Fixed • The selection toolbar of the title, search and vault fields offered other apps' text actions, and each of them received the selected text. Android lets any app add such an action, under any name; before Android 11 every installed app could. They are gone on every Android version, as they already were in the note body. The toolbar keeps Cut, Copy, Paste and Select all. ("Translate", which looked text up online, has been off since 3.1.1.) One loss to state: Android's Read aloud no longer appears in that toolbar; it stays reachable through its accessibility shortcut. Nothing else changes: same features as 3.2.1, still no network permission, the same 4 permissions. Which APK should I download? • notes-tech-universel-3.2.2.apk: works on every phone. If in doubt, pick this one. • notes-tech-arm64-v8a-3.2.2.apk: almost every phone since 2016, smaller. • notes-tech-armeabi-v7a-3.2.2.apk: older 32-bit phones. • notes-tech-x86_64-3.2.2.apk: emulators.
