This Privacy Policy explains how Serhiy Pylypyshko ("we", "us", or "our") handles user information when you use the Arkush mobile application (the "App", package pylyp.arkush).
We are committed to user privacy. The App is engineered as a local-first document reader and management tool. We do not collect, store, sell, or transmit your personal documents or browsing activity.
1. Storage Access & Local Document Processing
Permissions: MANAGE_EXTERNAL_STORAGE / READ_EXTERNAL_STORAGE
To provide core functionality—locating, organizing, reading, converting, and editing document formats (such as PDF, DOCX, XLSX, TXT, MD, CSV) stored on your device—the App requests file storage access.
- 100% On-Device Processing: All document parsing, rendering, text search, file conversion, and metadata caching happen exclusively locally on your device.
- Zero Remote Document Transmission: Your files, filenames, folder structures, and document contents are never transmitted, copied, or uploaded to any remote server or cloud service.
2. Information Collected by Third-Party Services
The App does not require user registration, accounts, or logins. We do not collect personal identifiers such as names, phone numbers, or email addresses.
However, to maintain software reliability, the App integrates the following third-party software development kits (SDKs):
Firebase Crashlytics (Google LLC)
- Purpose: Crash detection, diagnostics, and application stability analysis.
- Data Collected: Anonymous stack traces, device model, operating system version, and system state at the moment of a crash.
- Opt-Out & Advertising: Automatic Google Analytics data collection and Advertising ID (AD_ID) tracking are strictly disabled within the application.
