Secret Note

While new and convenient authentication methods like public key authentication, pattern authentication, and biometric authentication have emerged, password authentication remains the most commonly used authentication method.
However, remembering countless passwords to use many websites and services can be challenging.
Using multiple variation of a password is not essential solution.
This app was created to help this issue.

There are many stylish, colorful, and multi-functional note-taking apps.
However, it was difficult to find an app that encrypts stored information and credential, supports backup/restore functions, has a lock function, and deletes data if the unlock fails.
This app reduces the risk of data leakage even if your device is lost or stolen by providing one-day locking feature or data deletion feature when the unlock fails.
It also encrypts internal data and creates encrypted backup files, making it even more secure than a typical notepad.

We hope this small app will make your online life safer.

To use this app like a regular notepad, set both the Master Key input limit and the App Unlock attempt limit to 0 in the settings screen.
Since the app lock function is disabled, no actions will be taken to block access. Additionally, features such as locking until midnight or deleting data will not affect usage.
However, you may become vulnerable to brute-force attacks.

[Service Usage Precautions]
This app may have compatibility issues with certain operating systems.

Please use the in-app backup function regularly to store important information separately.
