About Gamesir App's Protection against Theft of User Data

Principle of Least Privilege

• Only Request Necessary Permissions: In the Android system, apps need explicit user authorization to obtain permissions. The Gamesir gamepad - related apps will only request file and folder permissions directly related to the functionality of the gamepad, such as reading specific game configuration files and storing users' custom gamepad configurations. They will not request permissions to access users' privacy data like photos, videos, or documents that are not relevant to the gamepad's functionality.
• Runtime Permission Management: During the app's operation, it requests permissions from users only when they are actually needed, rather than obtaining all possible permissions at once. For example, the app requests file read - write permissions only when the user needs to import or save a game configuration file. And after the operation is completed, the app will not hold this permission in the background for other unnecessary operations.

Data Access Restrictions and Isolation

• Sandbox Mechanism: The Android system provides an independent sandbox environment for each app. The Gamesir gamepad app can only access the files and data within its own sandbox and cannot directly access the sensitive data of other apps or the system. The file and folder permissions obtained by the app are only valid within its sandbox, ensuring the security of users' other data.
• Access Control List (ACL): Inside the app, a strict access control list is set up to limit which modules or functions can access specific files and folders and in what way. Only specific code modules related to the gamepad's functionality are allowed to read and write relevant files under specific conditions, and other unrelated modules cannot perform data access operations.

Encryption and Secure Transmission

• Encrypted Data Storage: For user data, such as gamepad configuration files, the app encrypts the data using encryption algorithms when storing it in the local file system. Even if the file is accessed illegally, since the data is encrypted, it is difficult for attackers to obtain the valid information.
• Secure Transmission Protocols: When the app needs to interact with the server, such as downloading gamepad firmware updates or uploading user feedback, it will use secure transmission protocols, such as the SSL/TLS protocol, to ensure the confidentiality and integrity of the data during transmission, preventing the data from being stolen or tampered with.

Code Review and Security Testing

• Strict Code Review: The development team of Gamesir conducts strict reviews of the app code to ensure that there is no hidden malicious code or vulnerabilities, avoiding unexpected data leakage risks. During the code - writing process, security coding standards are followed to prevent and handle potential security risks in advance.
• Security Testing: Before the app is released, comprehensive security testing is carried out, including vulnerability scanning, penetration testing, etc. By simulating various possible attack scenarios, the app is tested for data security issues, such as unauthorized data access and data leakage vulnerabilities. Only after passing all security tests will the app be officially released.
