DevsOfVirtue ("we," "our," or "us") provides the PDF Reader - PDF Viewer & Editor app (the "App"). We are committed to protecting your privacy. This Policy explains how we collect, use, and handle your information.
1. No Account & Local File Processing
No Registration: We do not require you to create an account. We do not collect personal identifiers such as your name, email address, or phone number.
Local Processing: The App is designed as a local tool. All file operations—including viewing, editing, format conversion, and scanning—are performed locally on your device. We do not upload your documents, music files, or images to any cloud server. Your private files remain exclusively in your control.
2. Information We Automatically Collect
To improve app stability and support our free services via advertising, we work with trusted third-party partners who may collect:
Device Information: Device model, OS version, time zone, language, and network connection type.
Identifiers: Advertising ID (GAID/IDFA) and Push Notification Tokens (FCM Token).
Usage Data: Crash logs, performance diagnostics, and feature usage statistics (e.g., "User opened PDF editor").
3. Permissions & Background Services
To provide specific features (File Management, Media Player, and Smart Reminders), we request the following permissions. You can manage these in your device settings.
Manage External Storage (All Files Access):
Purpose: Core functionality. Required to scan, list, read, edit, rename, and delete document files (PDF, Word, Excel, etc.) on your device.
Read Media Audio (Android 13+):
Purpose: Required for the built-in Music Player feature to identify and play audio files (MP3, WAV) stored on your device.
Foreground Service (Media Playback):
Purpose: Required to allow the integrated music player to continue playing audio in the background or when the screen is locked, ensuring an uninterrupted listening experience.
Foreground Service (Data Sync / Special Use):
Purpose: Used for the File Monitor Service to detect file system changes in real-time (e.g., new downloaded documents) and update the file list immediately.
Camera:
Purpose: Required for the "Scan to PDF" feature. Images are processed locally.
Post Notifications:
Purpose: To send you player controls, file status alerts, and utility reminders.
4. Third-Party Services (Advertising)
We use third-party SDKs to display advertisements. These partners may access your Advertising ID to show personalized ads. Please review their privacy policies:
Google AdMob & Firebase: https://policies.google.com/privacy
Facebook Audience Network (Meta): https://www.facebook.com/about/privacy/
AppLovin: https://www.applovin.com/privacy/
5. Push Notifications & Smart Reminders
We use local broadcasts and remote push notifications to provide:
Utility Alerts: Reminders about storage usage, new file detection, or file organization tips.
Promotional Content: Information about new features or partner offers.
Control: You can opt-out via Settings > Apps > PDF Reader > Notifications.
6. Data Security
We use administrative, technical, and physical security measures to help protect your personal information. Since files are stored locally, their security also relies on your device's security protections.
7. Changes to This Policy
We may update this Privacy Policy to reflect changes in our practices. We will notify you of any material changes by posting the new Policy in the App.
