About this app

MiJi is a privacy-focused local encrypted record tool designed to manage account information, private notes, and other important data.

Key Features
Account Management: Supports four types of records: accounts, bank cards, contacts, and files. Organize important information by category and find what you need quickly.
Private Notes: Supports rich-text editing with customizable text colors, font sizes, and styles. Home screen widgets make it easy to view and edit notes quickly.
Convenient Login: Supports three login methods: password, fingerprint, and pattern. If you forget your password, you can reset it using the options provided by the app.
Data Backup & Export: Supports encrypted data export and backup to help protect important information. Plain-text export is also available when you need to view or organize your data.
Personalized Experience: Supports multiple theme colors and allows you to customize the background and borders of home screen widgets.
Multi-language Support: Supports 中文, English, 日本語, Español, and Português.

Security
Key Derivation: Uses a dual key derivation mechanism combining Scrypt and PBKDF2WithHmacSHA256. Scrypt is first used to derive a key, which is then processed by PBKDF2WithHmacSHA256 for a second derivation. Dynamic salts and a high number of iterations are used to derive the final encryption key. The key is protected using the Android Keystore security module.
Active Protection: Includes multiple anti-cracking and anti-debugging mechanisms. When an abnormal runtime environment is detected, the encryption key is deleted to help reduce the risk of unauthorized access to data.

MiJi focuses on local data management and does not rely on a cloud account to store your records, helping keep your important information under your control.
