1. Introduction
Welcome to QRCode Master (hereinafter referred to as "the App"), a mobile application designed to generate, scan, and manage QR codes, supporting functions such as creating custom QR codes, decoding existing ones, and storing scan history. This Privacy Policy explains how we collect, use, store, and protect your information when you use the App. By accessing or using the App, you confirm that you have read, understood, and agreed to the practices outlined herein. We comply with applicable regulations including the General Data Protection Regulation (GDPR), California Consumer Privacy Act (CCPA), and Apple App Store guidelines to safeguard your privacy.
2. Information We Collect
2.1 User - Generated Content
QR Code Data: Information embedded in QR codes you generate (such as URLs, text, contact details, or Wi - Fi credentials) and records of QR codes you scan (including decoded content and timestamps) are considered user - generated content. This information is owned by you and managed according to your settings.
Account Information (Optional): If you choose to create an account, we may collect your email address (for account verification and password recovery) and a username (for profile display). We do not collect sensitive personal data like payment details or physical address unless explicitly provided by you for specific features.
2.2 Technical and Usage Data
To optimize the App's performance and user experience, we may automatically collect the following non - personally identifiable information:
Device details: Device model, iOS version, App version, camera specifications (for scanning functionality), and anonymized device identifiers (processed to prevent association with individual users).
Usage metrics: Frequency of App usage, most used features (e.g., QR code generation, scanning, history management), and types of content encoded/decoded (aggregated and not linked to individual users).
Error logs: With your consent, we may collect crash reports or technical errors to diagnose and fix issues. These logs do not contain QR code content, personal information, or scan history.
2.3 Camera and Storage Access (Optional)
The App requires camera access to scan QR codes. This access is used solely for capturing QR code images during scanning sessions and is not used to record or store unrelated photos/videos.
Storage access is required to save generated QR codes to your device's photo library (with your explicit action) or to import images containing QR codes for decoding. We do not access or monitor your entire photo library without your specific selection.
3. How We Use Your Information
Core Functionality: Your QR code data and account information (if applicable) enable essential features, such as generating and saving QR codes, storing scan history, and syncing data across devices (if using optional cloud sync).
App Improvement: Aggregated technical and usage data helps identify performance issues, optimize scanning accuracy for different QR code types, and develop new features that align with user needs.
Personalization: Based on your usage patterns, the App may suggest relevant templates (for generated QR codes) or quick - access tools (e.g., frequent scan types) to enhance efficiency.
Account Management: Your email address is solely used for account - related activities, such as verifying your account, sending password reset links, or notifying you of important updates.
4. Data Storage and Security
Local Storage Priority: By default, all generated QR codes, scan history, and preferences are stored locally on your device. You retain full control over this data, and it is not accessible to us or third parties without your explicit action.
Optional Cloud Sync: If you enable the optional cloud synchronization feature (powered by Apple's iCloud), your data will be synced across your authorized Apple devices in accordance with Apple's privacy policies. We do not access or store data synced via iCloud.
Security Measures: We use industry - standard encryption to protect locally stored data, including sensitive content within QR codes (e.g., contact details). Additionally, you can set up a passcode, Touch ID, or Face ID within the App to restrict unauthorized access to your scan history and account.
5. Information Sharing
We will never share, sell, or lease your QR code data, scan history, account information, or personal data with third parties for marketing, advertising, or commercial purposes.
We may disclose information if required by law (e.g., in response to a valid court order or subpoena) to comply with legal obligations. In such cases, we will provide only the minimum necessary information and notify you unless legally prohibited.
If you choose to share generated QR codes or scan results via third - party platforms (e.g., messaging apps, email), such actions are governed by the privacy policies of those platforms, not this Policy.
6. Your Rights
Access and Control: You can view, edit, delete, or export your generated QR codes and scan history at any time through the App's interface.
Account Management: You can update your account details (e.g., email address, username) or delete your account in the App's settings. Deleting your account will remove your account information from our systems, but locally stored QR code data and history will remain on your device unless manually deleted.
Data Portability: You can export generated QR codes in common formats (e.g., PNG, JPEG) or export scan history as a text file via the App's export feature, allowing you to save or transfer your data as needed.
Opt - Out Options: You can disable cloud synchronization, camera/storage access, error log collection, or personalized suggestions through the App's or device's settings.
7. Children's Privacy
The App is not intended for use by children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware of unintended data collection from a child under 13, we will promptly delete such information from our systems.
8. Policy Updates
We may revise this Privacy Policy periodically. For material changes, we will notify you via in - App notifications or email (if you have an account). The "Last updated" date at the top will be updated to reflect changes. Your continued use of the App after the effective date of updates constitutes acceptance of the revised Policy.
