About this app

WIN is not just a name, but a principle: Write, Isolate, Never leak. Write, Isolate, Never leak.

Write
• Record ideas, lists, and plans in a calm, clutter-free interface.

Isolate
• Your notebook is stored exclusively on your device.
• No accounts or cloud synchronization of notes.
• Enable optional PIN protection: the database is locally encrypted using SQLCipher AES-256.

Never leak
• Your notes are not uploaded to the cloud or transferred to third-party services.
• They only leave the application when you export or share them yourself.

Key features:
• Create, search, and organize notes.
• Local storage without registration.
• Optional PIN protection with database encryption.
• PIN brute-force protection with the option to automatically delete data after a specified number of attempts.
• Note reminders.
• Export and import backups via Android's system file picker.
• Encrypted backups when PIN protection is enabled.
• Disable Android cloud backup of the notes database.
• Russian language interface.
• Support for Android 10.0 and newer.

WIN Secure Note is designed for those who want to keep personal records under full control: without accounts, cloud synchronization, or unnecessary actions.

WIN. Write, Isolate, Never leak. Write. Isolate. Never leak.
