Welcome to ScanWise: QR & Barcode Scanner!
Developed by Qd App Developer, Scanwise is a free and privacy-focused application built for seamless QR and barcode scanning. This Privacy Policy explains how your information is handled when using our app. Your privacy is our top priority.
1. Our Commitment to Your Privacy
We do not collect, store, or share any personal information from our users for our own purposes — including your name, address, or contact details. However, when you choose to generate QR codes containing personal information such as email addresses, phone numbers, or physical addresses, we temporarily process this information solely for the purpose of creating the QR code. This data is processed locally on your device and is not stored or transmitted to our servers.
Local Processing:
All QR code and barcode scans are processed entirely on your device. No scanned data is transmitted to our servers or stored externally. Your scan results remain private and secure.
2. Permissions We Use (and Why)
To provide a complete scanning experience, Scanwise requires a few essential permissions. Below is a breakdown of what we access and how it's used:
📷 Camera
Purpose: Required for real-time QR and barcode scanning.
Usage: The camera is only used when scanning and never records, stores, or uploads your footage.
🖼️ Media Access (READ_MEDIA_IMAGES / READ_EXTERNAL_STORAGE)
Purpose: Lets you select QR/barcode images from your device's gallery.
Usage:
On Android 13+ (API 33+), we use READ_MEDIA_IMAGES to access images.
On Android 12 and below, we use READ_EXTERNAL_STORAGE.
In both cases, image processing is done locally and nothing is uploaded or shared.
💾 Storage (WRITE_EXTERNAL_STORAGE / MediaStore)
Purpose: Allows you to save generated QR codes to your device's gallery.
Usage:
On Android 10 and above, we use MediaStore API to save images.
On Android 9 and below, we use WRITE_EXTERNAL_STORAGE permission.
In both cases, images are saved only to your device's local storage and we do not access them afterward.
🌐 Internet
Purpose: Only used when:
You tap on a scanned URL.
You choose to connect to a Wi-Fi network via QR code.
Note: The app functions offline for scanning.
📶 Wi-Fi State Access
Purpose: Enables automatic connection to Wi-Fi networks from scanned QR codes.
Usage: We use ACCESS_WIFI_STATE and CHANGE_WIFI_STATE to facilitate the process. No Wi-Fi credentials are stored or shared.
3. Data Collection for QR Code Generation
When you generate QR codes containing personal information (email addresses, phone numbers, physical addresses), we process this data solely for the purpose of creating the QR code. This data:
Is processed locally on your device
Is not stored on our servers
Is not shared with third parties
Is not used for any other purposes beyond QR code generation
Is deleted immediately after the QR code is created
When you generate QR codes and choose to save them to your device's gallery, the QR code image is stored locally on your device. We do not access or control these saved images after they are saved to your gallery.
