PrivateBox

PrivateBox is a privacy-first personal vault that keeps your notes, passwords, and tasks safely locked behind a 4-digit PIN. Everything stays on your device — nothing is uploaded, synced, or tracked. No accounts, no cloud, no internet needed.

YOUR PRIVATE VAULT — 3 SECTIONS:

Notes — Write and organize personal notes with titles and timestamps. Search across all your notes instantly. Select multiple notes and delete them in bulk when you need to clean up.

Passwords — Store login credentials with username, password, website, and notes. Organize them into 7 categories: Email, Social, Banking, Work, Wi-Fi, Shopping, and Other. Mark important entries as favorites. Copy passwords to clipboard with automatic clearing after 30 seconds for safety. Open saved website URLs directly from the app. Need a strong password? Use the built-in password generator.

Tasks — Manage your to-do list with titles, descriptions, priority levels (High, Medium, Low), and optional due dates. Organize tasks into 5 categories: Personal, Work, Shopping, Health, and Other. Filter by status — All, Pending, Completed, or Overdue. Sort by due date, priority, or recently added. Mark tasks as complete with a single tap.

SECURITY FEATURES:

4-Digit PIN Protection — Your vault is locked behind a PIN that you set during first launch. The PIN is hashed using SHA-256 with a unique salt — it is never stored as plain text.

Lockout Protection — Too many wrong PIN attempts? The app locks you out with escalating cooldown timers (30 seconds, 5 minutes, up to 15 minutes) to prevent brute-force access.

PIN Recovery — Forgot your PIN? Answer your self-chosen security question to reset it. The security answer is also hashed and salted — never stored in readable form.

Screenshot Blocked — While the vault is open, screenshots and screen recording are automatically blocked. Even the recent-apps preview shows a blank screen instead of your data.

No Backup Extraction — App data is excluded from Android backup and extraction, so your vault cannot be pulled off the device through ADB or cloud backup.

KEY FEATURES:

Search Everything — Quickly find any note, password, or task using the search bar in each section. Results appear as you type with a smooth debounced search.

Bulk Actions — Select multiple items across notes, passwords, or tasks and delete them all at once. No need to remove entries one by one.

Password Generator — Create strong, random passwords right inside the app when adding or editing a password entry.

Clipboard Safety — When you copy a password, it is automatically cleared from your clipboard after 30 seconds to prevent accidental exposure.

Guided Setup — A simple 3-step first-time wizard walks you through usage guidelines, PIN creation, and security question setup. No confusion, no skipped steps.

Clean Design — A polished interface with smooth animations, gradient theme, and haptic feedback. Built for everyday use without clutter.
