This document details the data practices of the PDF Viewer mobile application (the "Application"). We are dedicated to ensuring the privacy and security of your information. This policy is designed to be clear and straightforward, explaining exactly what information is involved when you use our Application.
Your files stay on your device. The primary functions of PDF Viewer—such as viewing, editing, converting, and managing PDF files—are executed entirely on your mobile device. We do not upload or transmit the content of your personal documents to our servers or any external parties.
To guarantee the Application's stability and proper performance across various devices, we automatically collect specific technical data. This data is used solely for diagnostics, maintenance, and technical improvement and cannot be used to personally identify you.
Device Specifications: Model, manufacturer, and operating system version (e.g., Android 14).
Connection Info: Basic mobile network data and unique device identifiers.
We monitor the health of the Application by collecting anonymized statistics about its usage. This helps us locate bugs and popular features.
Usage Patterns: General information on how often specific features are used (e.g., "Merge PDF" is used frequently).
System Reports: Logs generated if the app unexpectedly closes (crash logs), used exclusively for troubleshooting and bug fixes.
PDF Viewer is provided free of charge and is supported by integrated advertisements. These ads are served by third-party advertising networks, which may collect certain data to display relevant advertisements.
The data collected by our ad partners typically includes:
Advertising Identifier (e.g., your device’s unique ad ID).
IP Address (used to estimate general location for geotargeted ads).
Information about your interactions with the ads shown.
The privacy policies of these independent advertising providers govern the handling of this data. Our current partners include, but are not limited to, AppLovin, Admob (Google), Facebook (Meta), Pangle, Vungle, and MTG. We encourage you to review their respective policies.
To offer comprehensive file management capabilities, such as allowing you to navigate and select documents from any folder on your storage, PDF Viewer requires the "All Files Access" permission (MANAGE_EXTERNAL_STORAGE). This powerful permission is used strictly to enable the file browsing and saving functions you activate within the Application interface.
