Voidtype

Voidtype is a minimalist, secure typing space for Android. It allows you to type freely, knowing your thoughts are encrypted locally and will vanish automatically after 30 days.

Features

• Minimalist Interface: A distraction-free environment for typing.
• Secure Encryption: All notes are stored locally using AES-256 encryption.
• Biometric Lock: Secure your vault with your device's biometric authentication (Fingerprint/Face Unlock).
• Ephemeral Storage: Notes are automatically deleted after a configurable period (1-30 days), encouraging you to let go.
• Auto-Clear: Optional setting to save and clear the text field immediately upon pressing Enter.
• Customizable: Adjust text size (Small, Medium, Large) and retention period to suit your preference.
• Vault: View and manage your encrypted notes. See how many days are remaining for each note or delete them individually.
• Privacy Focused: No internet permission required. Your data never leaves your device.

Getting Started

1. Set Up: Upon first launch, you will be guided through a tutorial and asked to set an encryption key (password).
2. Type: Start typing in the main screen.
3. Save: Press the "Save & Clear" button (or Enter if Auto-clear is enabled) to encrypt and save your note.
4. Vault: Access your saved notes via the menu. Tap a note to decrypt and view it.
