1. Introduction
Welcome to Document Reader ("we," "our," "us"). We are committed to protecting your privacy and ensuring that your personal information is handled in a safe and responsible manner. This Privacy Policy outlines how we collect, use, disclose, and protect your information when you use our Document Reader application ("App"), which supports the viewing of Word, Excel, PPT, and PDF files.
2. Information We Collect
Since Document Reader does not collect any personal information and does not support user account creation, the information we collect is limited to non-personal data necessary for the App's functionality and performance.
2.1. Non-Personal Information
Device Information: We may collect information about your device, including the device type, operating system, unique device identifiers, and mobile network information. This data is used to ensure compatibility and optimize performance.
Usage Data: We may collect information about how you interact with the App, such as the types of files you open, the time spent on the App, and any errors or crashes that occur. This helps us improve the user experience.
Log Data: We may collect log information, including your IP address, browser type, and access times. This data is used for troubleshooting and security purposes.
2.2. File Data
File Content: The App allows you to view Word, Excel, PPT, and PDF files. We do not store the content of these files on our servers. All file processing occurs locally on your device.
File Metadata: We may collect metadata associated with the files you open, such as file names, sizes, and modification dates. This metadata is used solely for the purpose of enabling file viewing functionality.
3. How We Use Your Information
We use the information we collect for the following purposes:
To Provide and Improve the App: We use non-personal information to operate, maintain, and improve the functionality of the App.
To Analyze Usage: We use usage data to understand how users interact with the App and to improve its performance and user experience.
To Ensure Security: We use log data to monitor and protect the security of the App, including detecting and preventing unauthorized access and other malicious activities.
4. Sharing Your Information
We do not sell, trade, or otherwise transfer your information to third parties. However, we may share non-personal information in the following circumstances:
Service Providers: We may share non-personal information with third-party service providers who assist us in operating the App, conducting our business, or providing services to you, as long as these parties agree to keep this information confidential.
Legal Requirements: We may disclose non-personal information if required to do so by law or in response to valid requests by public authorities (e.g., a court or government agency).
Business Transfers: In the event of a merger, acquisition, or sale of all or a portion of our assets, non-personal information may be transferred to the acquiring entity.
5. Data Security
We implement a variety of security measures to protect your information, including encryption, access controls, and secure servers. However, no method of transmission over the internet or electronic storage is 100% secure, and we cannot guarantee absolute security.
6. Your Rights and Choices
Access and Correction: Since we do not collect personal information, there is no personal data to access or correct.
7. Children's Privacy
The App is not intended for use by children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that we have collected personal information from a child under 13, we will take steps to delete such information.
