I. Information We Collect and Use
1. Device Information
To ensure the normal operation of the App, we may collect information such as device model, operating system version, unique device identifiers, and network-related information (e.g., IP address). This data is used solely to optimize App performance, improve user experience, and conduct statistical analysis.
2. File Storage and Access
The core functions of the App include scanning, managing, generating, and converting PDF files. To provide these features, we require the android.permission.MANAGE_EXTERNAL_STORAGE (all files access permission).
This permission is strictly limited to:
Reading and writing PDF files stored on your device;
Supporting batch operations to save you from selecting files one by one;
Enabling document viewing, saving, exporting, and conversion features.
We do not collect, upload, or share the contents of your personal documents.
3. Advertising and Analytics
This App integrates third-party advertising platforms (including TopOn, Vungle, UnityAds, IronSource, Pangle, Facebook, AdMob, AppLovin, and Chartboost) to provide ads and support free usage of the App.
These ad platforms may collect device identifiers, location data based on IP, usage preferences, and other information to deliver personalized ads.
The App also integrates Firebase for analytics to help improve performance and stability. This data is used in aggregate form and does not personally identify you.
II. Children’s Privacy
This App is intended for users aged 13 and above.
We do not knowingly collect personal information from children under 13. If we learn that information from a child under 13 has been collected, we will promptly take action to delete it. If you are a minor (13–18 years old), please use the App only with the consent and supervision of a guardian.
III. Information Storage and Security
1. Information Storage
Data generated by the App is primarily stored locally on your device.
Advertising and analytics-related data may be stored on third-party service providers’ servers.
2. Information Security
We implement reasonable security measures to protect your information from loss, misuse, unauthorized access, or disclosure. However, please understand that due to the nature of the internet, we cannot guarantee absolute security.
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 storage permissions or ad personalization settings at any time in your device settings, though certain features may not function properly afterward.
Discontinuing Use: If you do not agree with this Privacy Policy, you may uninstall and stop using the App at any time.
V. Third-Party Services
Because the App integrates multiple advertising and analytics SDKs as described above, these third-party providers may collect and process user information for advertising and analytics purposes. Their data processing practices are subject to their respective privacy policies.
VI. Updates to This Privacy Policy
We may update this Privacy Policy from time to time to reflect feature changes or legal requirements. Updated policies will be prominently displayed within the App or on its app store page. Please review the latest version before continuing to use the App.
