Password Pattern Notes is a private offline notebook for people who care about privacy. Every note is protected by a PIN and encrypted on your device. No accounts, no sync, no cloud — your entries stay with you only.

🔒 SECURITY
• 4–6 digit PIN — your only key to the vault
• Note content encrypted with AES/GCM using a PIN-derived key (PBKDF2)
• Your PIN is stored only as a salted hash, never in plain text
• Auto-lock after inactivity (immediately, 1, 5, or 15 minutes)
• Change PIN with automatic re-encryption of all notes

📝 NOTES MADE SIMPLE
• Create, edit, and delete private entries
• Color-coded categories to stay organized
• Favorites for quick access to important notes
• Instant local search by title, body, and category
• Sort by date, title, or category

🎨 YOUR STYLE
• Four themes: Midnight Lock, Soft Paper, Blue Vault, Warm Notes
• Clean, modern interface built for everyday use

🛡️ PRIVACY WITHOUT COMPROMISE
• Fully offline — the app never uses the internet
• Zero Android permissions — no camera, contacts, storage, or other access requests
• No ads, no analytics, no tracking
• No accounts or cloud backup
• Your data never leaves your device

⚙️ DATA CONTROL
• Clear all notes while keeping your PIN
• Full app reset to erase all local data

Password Pattern Notes is built for people who want a simple, reliable, fully local way to store personal thoughts, passwords, ideas, and any sensitive information.

Important: there is no online PIN recovery — this is a deliberate privacy choice. If you forget your PIN, the only option is a local reset that permanently deletes all notes on this device.
