Effective Date: May 26, 2026
This Privacy Policy explains how the PDF Converter mobile application ("Application", "App", "we", "our", or "us"), developed under the package name quality.premium.pdfconverter, handles user data and privacy.
We are committed to protecting your privacy and ensuring transparency about how the Application operates. This policy explains what information the App accesses, how it is used, and how we comply with Google Play Developer Policies.
The Application operates entirely offline.
The App does not transmit data over the internet.
Internet and network state permissions have been removed from the Application.
All document processing, file conversion, image editing, scanning, and database storage occur locally on your device.
The Application does not collect, upload, store on external servers, or share:
Documents
Images
PDF files
Scanner contents
User preferences
Passwords
Personal information
All processing remains fully on-device.
To provide document conversion and editing features, the Application may request the following permissions.
android.permission.READ_EXTERNAL_STORAGE
(Android 12 and below)
android.permission.WRITE_EXTERNAL_STORAGE
(Android 9 and below only, restricted with maxSdkVersion="28")
These permissions allow the App to:
Read documents and files selected by you
Convert supported files into PDF format
Save generated PDF files to your device storage
Supported formats may include:
.txt
.xls
.xlsx
.doc
.docx
All files are processed locally on your device using document-processing libraries. No file content is uploaded, transmitted, or shared with third parties.
android.permission.READ_MEDIA_IMAGES
(Android 13+)
android.permission.READ_MEDIA_VISUAL_USER_SELECTED
(Android 14+)
These permissions allow you to:
Select images from your gallery
Convert images into PDF files
Edit or crop images before conversion
The App only accesses images you explicitly select. All image processing occurs locally on your device.
android.permission.CAMERA
Camera access is required for scanning:
QR codes
Barcodes
for the QR-to-PDF conversion feature.
When a QR code or barcode is scanned:
The scanned content is temporarily written to a cache file within the App’s private cache directory.
The content is immediately used to generate the PDF file.
The scanned data never leaves your device and is never transmitted over any network.
The Application stores limited information locally on your device to support functionality and improve user experience.
The App maintains a local conversion history that may include:
File paths
Operation dates
Action types such as:
Created
Merged
Watermarked
This information is stored only on your device.
The App may locally store user preferences such as:
Default page size
Font size
Font family
Image compression settings
PDF protection settings
All stored data remains private to the Application and is not accessible by other applications under normal Android security restrictions.
No data is uploaded or shared externally.
The Application uses several open-source components to support document conversion, image editing, QR scanning, PDF generation, and encryption features. All processing is performed locally on your device.
These components may include:
iTextG
For PDF generation and editing
Apache POI & XMLBeans
For reading Microsoft Word and Excel documents
ZXing
For QR code and barcode scanning
Picasso
For local image rendering
PhotoEditor & Android Image Cropper
For image editing and cropping
Spongy Castle
For cryptographic operations and PDF encryption
These components operate entirely offline within the Application.
They do not collect, transmit, track, or share user data.
The Application also does not use:
Advertising SDKs
Analytics services
Online crash reporting services
User tracking technologies
When you choose to open or share a generated PDF file, the App uses Android’s secure FileProvider mechanism (quality.premium.pdfconverter) to grant temporary access to selected files for compatible applications such as:
PDF viewers
Email clients
Printing services
Certain actions, such as:
Rating the App
Opening the Google Play Store
Sharing a download link
are performed using standard Android system intents, which may open your browser or the Google Play Store application.
We implement appropriate measures to protect locally stored information.
Because all data remains on your device, security depends largely on your device’s built-in protections, including:
Screen locks
Device encryption
Android security controls
The App provides optional password protection and PDF encryption features for generated PDF files.
Since all data remains on your device, you have full control over its storage and deletion.
Remove PDF files at any time using your device’s file manager.
Delete conversion history directly within the Application.
You can erase all locally stored settings, passwords, and history by:
Settings > Apps > PDF Converter > Storage > Clear Data
or by uninstalling the Application.
