LockNote is the ultimate secure notepad designed to give you 100% ownership and privacy over your personal data. Protect your thoughts, ideas, passwords, and sensitive information with industry-standard AES encryption. Your notes stay on your device, and only you hold the key to unlock them.
🔒 INDUSTRY-STANDARD ENCRYPTION & PRIVACY
Your privacy is our absolute priority. LockNote protects your notes using secure AES (Advanced Encryption Standard).
• Zero-Knowledge Privacy: We do not host your data on external servers. Your notes and passwords remain exclusively on your device. We have NO way to access, read, or recover your information.
• Secure Password Derivation: The encryption key is derived directly from your user password, adding an unbreakable layer of security.
• Anti-Spy Protection: The app prevents screenshots and screen recordings, and automatically obscures content previews in the Android "Recent Apps" list to prevent accidental shoulder-surfing.
🛡️ ADVANCED ACCESS CONTROL & SECURITY
• Biometric & Password Lock: Unlock your notes instantly using your fingerprint or face recognition, backed by a master password.
• Brute-Force Prevention: If an incorrect password is entered 3 times, the app automatically locks for 10 minutes, stopping unauthorized attempts.
• Intrusion Alerts: Every time you log in, a system message alerts you if a login attempt occurred, displaying the exact date and time.
• Smart Auto-Logout: Keep your data safe even if you leave your phone unlocked. The session automatically expires and logs out after a customizable period of inactivity, both in the foreground and background.
🎨 ORGANIZATION & POWERFUL FEATURES
LockNote isn't just secure—it’s also a flexible and productive daily journal:
• Priority Levels: Organize your notes by marking them as "Normal" or "Important", each with distinct, customizable colors.
• Smart Filters: Instantly filter your dashboard to display only important notes, normal notes, or all of them at once.
• Advanced Built-in Search: Find what you need in seconds. Our powerful search feature scans all your notes and highlights the matching words instantly.
• Fully Customizable: Make it yours. Change the text size, customize colors for different note priorities, and adjust session timeout limits in the settings menu.
💾 SECURE BACKUP & RESTORATION
• Encrypted Export: Generate a highly secure, encrypted backup file of your notes. You can save it anywhere you prefer—such as your personal cloud storage (Google Drive, OneDrive, etc.) or PC—to protect your data from device theft or damage.
• Easy Data Recovery: Restore your notes easily using your manual encrypted backup file or through Google’s automatic account backup.
⚠️ IMPORTANT SECURITY NOTICE:
Because LockNote is a 100% offline and private app, your password is encrypted and impossible for us to recover or reset. If you forget your password and do not have an encrypted backup file, access to your notes will be permanently lost. We strongly recommend keeping your master password in a safe place and performing regular backups.
Download LockNote today and take full control of your privacy with the most secure, offline, and private notepad available.
Note: LockNote is the new, evolved and rebranded version of Secure Memo.
