Our app is an innovative tool designed to help users manage their personal finances efficiently and securely. With a focus on simplicity and ease of use, this app allows users to record and monitor their work income and expenses quickly and easily.

Main Features:

Secure Authentication: The application uses BiometricPromptInfo to ensure that only the owner of the device can access the stored information. This authentication is done using a fingerprint, providing an additional level of security. To use the app, users must have a device that has fingerprint unlock capability, and must register their fingerprint on the device before logging in.

Intuitive Interface: Upon opening the application, users are greeted by a splash screen that lasts approximately 7 seconds, followed by a login activity that presents a button that says "Go to Main Menu." This friendly interface is designed to facilitate navigation and access to the app's features.

Income and Expense Registration: Once authenticated, the user is redirected to the main activity, where they can access the main menu. Here, you will be able to record your work income and expenses in a simple way. The app uses an SQLite database to store this information within the device, allowing for quick and efficient access to the data.

Expense Control: The app not only allows data recording, but also helps users keep track of their personal finances. By having a clear record of their income and expenses, users can make informed decisions about their expenses and save more effectively.

Privacy and Data Security: It is essential to highlight that our application does not collect or store sensitive personal information, such as email accounts or PINs. The sole purpose of biometric authentication is to allow secure access to the application, thereby protecting user privacy. The app is designed to be a secure and reliable solution for managing personal finances.

Limitations of Use: It is important to mention that if the user's device does not have a fingerprint reader, the application will not be able to work. This limitation ensures that only authorized users can access the information stored in the app, reinforcing security and privacy.

No sensitive user data is recorded, only entry and exit data is scheduled so that the end user can have control of their expenses over time.
