Effective Date: February 28, 2026
Welcome to PDF Reader - Editor & Viewer (hereinafter referred to as "the App"). We are committed to protecting your privacy while providing professional PDF viewing, editing, and management services. This policy explains how we handle your information and ensures that your personal data remains private.
1. INFORMATION WE COLLECT
To provide high-quality document services, we may collect the following types of information:
Device Information: Hardware model, operating system version, unique device identifiers (e.g., Android ID), and IP address. This helps us ensure the PDF renderer is compatible with your specific hardware.
Storage Access: To open, read, and save PDF files, we require permission to access your device’s storage.
Usage Data: Anonymous data regarding app performance, crash logs, and feature usage (e.g., which editing tools are used most) to help us improve the user experience.
2. DATA PROCESSING: "LOCAL-FIRST" GUARANTEE
We prioritize your privacy through a Local Processing architecture:
No Document Uploads: All PDF viewing and editing (including text modification, annotation, and merging) are performed locally on your device. We do not upload, store, or monitor your private documents on our servers.
Secure Processing: Any temporary files created during the editing process are stored in the app's secure internal cache and are cleared according to system protocols.
3. THIRD-PARTY SERVICES
We may use third-party SDKs (such as Google AdMob or Firebase Analytics) for monetization and performance monitoring. These partners may collect your Advertising ID (GAID) to provide non-personalized ads or analytics.
Note: These third parties operate under their own privacy policies. We encourage you to review them.
4. YOUR RIGHTS AND CONTROL
You maintain full control over your data:
Revoke Permissions: You can withdraw storage or camera (if used for scanning) permissions at any time via your device settings.
Data Deletion: Since we do not require account registration, we do not store personal profiles. Uninstalling the app will remove all local app-specific data.
5. CHILDREN’S PRIVACY
Our App is not intended for children under the age of 13. We do not knowingly collect personal information from children.
6. CHANGES TO THIS POLICY
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page. Your continued use of the App after changes are made signifies your acceptance of the new terms.
