I. Information We Collect and Use
1. Device Information
To ensure the proper functioning of the App, we may collect information such as device model, operating system version, unique device identifiers, and network information (such as IP address). This information is only used to optimize App performance, enhance user experience, and conduct statistical analysis.
2. File Storage and Access
The core functionality of this App is scanning, managing, generating, and converting PDF files. To do this, we require `android.permission.MANAGE_EXTERNAL_STORAGE` (all file access permissions).
This permission is only used to:
Read and write PDF files on the user's device;
Support batch operations to avoid users having to manually select files one by one;
Enable document viewing, saving, exporting, and conversion.
We do not collect, upload, or share your personal document content.
3. Advertising and Analytics
This app integrates with third-party advertising platforms, including TopOn, Vungle, UnityAds, IronSource, Pangle, Facebook, AdMob, AppLovin, and Chartboost, to serve ads and maintain the app's free use.
Ad platforms may collect device identifiers, location information (based on IP), usage preferences, and other information to deliver personalized ads.
This app also integrates with Firebase for statistical analysis and improving app performance; it will not be used to personally identify you.
II. Children's Privacy Protection
This app is intended for users aged 13 and above.
We do not actively collect personal information from children under the age of 13. If we discover that a user is under the age of 13, we will immediately take steps to stop data collection and delete the relevant information. If you are a minor (13-18 years old), please use this app with the consent and guidance of your guardian.
III. Information Storage and Security
1. Information Storage
Data generated by the app is primarily stored locally on the user's device.
Data related to advertising and analytics may be stored on the servers of third-party service providers.
2. Information Security
We implement reasonable security measures to prevent the loss, misuse, unauthorized access, or disclosure of your information.
However, please note that due to uncontrollable risks in the online environment, we cannot guarantee the absolute security of your information.
IV. Your Rights
You have the following rights regarding your information:
Access and Management: You can directly access, modify, or delete PDF files on your device.
Revoking Permissions: You can disable app storage permissions or ad personalization settings at any time in the system settings, but some features may not function properly.
Discontinuing Use: If you do not agree to this Privacy Policy, you may uninstall and discontinue use of the app at any time.
5. Third-Party Service Description
Because this app integrates multiple advertising and analytics SDKs (as described above), these service providers may collect and process some user information for purposes such as advertising and statistical analysis. Please note that these data processing practices are subject to the privacy policies of each service provider.
6. Updates to This Privacy Policy
