This Privacy Policy describes how your information is handled by the "QR Code Scanner" mobile application (the "App"), developed by Hasnain Haider ("we," "us," or "our").
Our Commitment to Privacy Your privacy is important to us. While the core scanning functionalities of the App are designed to work locally on your device, we use certain third-party services to display advertisements and analyze app performance to improve your experience.
Information Collected and Stored Locally on Your Device The App handles data that you create or scan, but this personal data remains exclusively on your device:
Scanned History & Generated Codes: Any data from QR codes you scan or create is stored locally. We do not have access to this information.
App Settings: Your preferences are stored locally on your device.
App Permissions and Local Data Usage The App requests certain permissions to enable its core features. All data accessed through these permissions is processed on your device and is never sent to our servers:
Camera (NSCameraUsageDescription): Required solely to scan QR codes and barcodes in real-time. We do not store, record, or transmit the camera feed.
Photo Library: Required to select an existing image for scanning or to save generated QR codes to your gallery.
Calendar (NSCalendarsUsageDescription): Required to add scanned calendar events (vEvent) directly to your device's calendar.
Contacts (NSContactsUsageDescription): Required to save scanned contact information (vCard) to your address book.
Wi-Fi Configuration: For QR codes containing Wi-Fi credentials, the App can request the system to join that network on your behalf.
Third-Party Data Collection and Advertising To keep the App free and understand how users interact with it, we use third-party services (such as Google AdMob and analytics providers). These third parties may collect certain non-personally identifiable information, including:
Identifiers (Device ID): Used for third-party advertising and analytics.
Usage Data (Advertising Data & Product Interaction): Information about the advertisements you interact with and how you use the App's features.
Diagnostics (Crash Data & Performance Data): Crash logs and app performance metrics to help us fix bugs and improve stability.
App Tracking Transparency (iOS) If you are using iOS 14.5 or later, the App will ask for your permission to track your activity across other companies' apps and websites for targeted advertising purposes (NSUserTrackingUsageDescription). If you choose "Ask App Not to Track," we will not use your device's advertising identifier (IDFA) for personalized ads.
Data Sharing We do not sell your personal data. We only share the automatically collected diagnostic, identifier, and usage data with our trusted third-party advertising and analytics partners to support and improve the App.
Children's Privacy The App is not intended for use by children under the age of 13. We do not knowingly collect any personal information from children.
Changes to This Privacy Policy We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy within the App or on our website.
