2. Permission Application Description

1. Timing of Permission Requests: This application will prompt and seek your authorization in a system pop-up window only when you first use a function that requires a specific permission. Permissions will not be called without authorization.

2. Scope of Permission Use: Limited to the current function use, there will be no unauthorized use in the background or other unrelated scenarios.

3. Impact of Refusing Authorization: You have the right to refuse authorization. After refusal, only the corresponding functions (such as scanning or automatic backup) will be unavailable, without affecting the normal operation of unrelated features.

3. User's Control

Permission Management: You can view and manage permission status (enable or disable) at any time through the device's [Settings] feature and find this application.

Withdrawal of Authorization: Once you disable a certain permission, we will no longer collect device information corresponding to that permission.

4. Information Security Commitment

We commit to:

• Not obtaining permissions unrelated to the service;
• Not invoking permissions without your explicit consent;
• Not using permission information for unspecified purposes;
• Ensuring your data security by adopting industry-standard security technical protection measures during the use of permissions.
