Private, encrypted, and beautifully minimal. Your thoughts stay yours — always. No ads. No tracking. No cloud. Just notes.
Features
Void Note is packed with premium features — for free. No paywalls on core functionality. Ever.
Every note is encrypted before it touches storage. Master key lives in Android Keystore (hardware-backed). Zero-knowledge by design.
No network required. Ever. Your data never leaves your device unless you explicitly choose to export it. No accounts needed.
Fingerprint or face unlock. Vault password as fallback. Your notes open only for you.
Lock any folder with its own independent password — separate from your vault password. Protected folders re-lock automatically when the app is backgrounded.
Bold, italic, underline, strikethrough. H1/H2/H3 headings. Numbered lists with auto-continue. Interactive checklists. Color-coded notes. All the tools you need — none of the bloat.
Export your entire vault as an encrypted .vnbackup file. Restore on a new device. Your key never leaves your device.
A dedicated diary separate from your regular notes. Month-view calendar with dot indicators on days that have entries.
Three widgets. 1×1 Quick Note, 1×1 Voice Record, and a 4×2 recent notes glance. All capture happens without opening the app. Locked notes never appear.
Organise with nested folders and up to 5 tags per note. Browse by tag, folder, or search everything at once.
Connect related notes with a tap. Linked notes appear as chips above the tags bar.
Five built-in structures: Meeting Notes, Self-Reflection, Prioritised Todo List, Book/Movie Review, and Blank.
Attach encrypted voice recordings and images directly to notes. All files encrypted at rest.
Three carefully crafted themes. Extra Dark mode uses true #000000 black for OLED screens. G.I.P ecosystem design throughout.
Monospace dark-surface blocks embedded right inside your notes. Optional language label and horizontal scroll.
Focus Mode hides UI elements for a pure canvas. Format Preview renders styles without leaving the editor.
Archive notes without deleting. Trash with 30-day auto-cleanup running in the background.
Privacy isn't a feature toggle. It's the foundation. VoidNote was designed encryption-first — your notes are encrypted before they are ever written to disk.
The master encryption key lives in Android's hardware-backed Keystore. It never exists in plain memory longer than needed.
Every note title, content, and tag is encrypted individually. GCM mode provides authenticated encryption — tampered data is detected.
Your vault password is never stored. It's run through PBKDF2 to derive the encryption key. The salt is stored — the password never is.
THE PROMISE
We built Void Note because we were tired of note apps that spy on you, show you ads, or lock core features behind subscriptions.
No advertisements. No sponsored content. Not now. Not ever.
No analytics SDK. No crash reporters. No telemetry of any kind.
Core features work completely offline. No account required. Your data, your device.
Encryption is not a premium feature. Privacy is not a subscription tier.
