QR Scanner Privacy Policy
Effective Date: [August 26, 2025]
This Privacy Policy (the "Policy") describes how [Hefei Yinuo Network Technology Co., Ltd.] (referred to as "we" or the "developer") collects, uses, discloses, and protects your personal information when you use our mobile application [QR Scanner Pro] (the "App").
By using this App, you agree to the collection and use of your personal information as described in this Policy. If you do not agree with the terms of this Policy, please do not use this App.
1.Information We Collect
1.1. Information You Directly Provide to Us
When you use specific features of this App, you may be required to actively provide the following information, the provision of which is entirely voluntary:
User Content: Content you create, upload, or share within the App (such as text used to generate QR codes, saved QR code images, etc.).
Communication Information: When you contact us via email or in-app messages, we collect your communication content (such as a description of the problem, feedback) and contact information (such as your email address).
1.2. Automatically Collected Information
When you use this App, we automatically collect the following non-identifiable information through the application's backend and tools to ensure the normal operation and optimization of the App:
Device Information: Your device model, operating system version, unique device identifiers (such as IMEI, Android ID), IP address, and mobile network operator information.
Usage Information: Your behavior when using the App (such as pages visited, frequency of use, session duration) and application logs (such as crash records, error reports).
Location Information: We may collect your precise or approximate location information only after you have granted explicit authorization (used to support location-based features; if you do not grant authorization, this information will not be collected).
Log Information: Details of your interaction with the App (such as the time of function calls, operation paths).
1.3. App Permissions and Privacy Usage Description
The App will request necessary permissions based on feature requirements. We will only collect relevant information after you grant permission, and all information processing adheres to the "local-first, minimum necessary" principle:
Permission Name
Permission Purpose
Data Processing Rules
android.permission.INTERNET (Network Permission)
Supports basic network communication for the App (e.g., accessing online services, data required for synchronization)
No personally identifiable information is collected; it is only used to ensure the operation of core App functions.
android.permission.CAMERA (Camera Permission)
Implements QR code/barcode scanning functionality
All images and scanned content from the camera are processed locally on the device and are not uploaded to the server.
android.permission.READ_EXTERNAL_STORAGE / android.permission.WRITE_EXTERNAL_STORAGE / android.permission.READ_MEDIA_IMAGES (Storage Permission)
Reads images you select from your device's photo album (for QR code scanning) and saves generated QR code images.
Only accesses image files you explicitly select; does not batch scan or upload other stored files on the device; for Android 13 and above, READ_MEDIA_IMAGES permission is prioritized to comply with system privacy requirements.
android.permission.READ_CLIPBOARD (Clipboard Permission)
Reads clipboard content (for quick QR code creation)
Reads content only when you actively trigger the "Create QR Code from Clipboard" function; does not monitor or store clipboard data in the background.
android.permission.ACCESS_NETWORK_STATE (Network Status Permission)
Checks the device's network connection status (e.g., Wi-Fi/mobile data) to optimize network request efficiency.
Only used locally to determine network status; no user information is collected.
The INTERNET and ACCESS_NETWORK_STATE permissions listed in the table in section 1.3 are necessary for the basic operation of the App. If you deny these permissions, core functions of the App may not be usable. The CAMERA, storage, and clipboard permissions are required for specific features (such as scanning codes and saving QR codes). You may refuse to grant them, and this will not affect the normal use of other App functions.
1.4. Hardware Feature Requirements
Camera Functionality: Declares android.hardware.camera, for QR codes. This feature is "optional," and devices without a camera can still use other functions of the App (such as generating QR codes from text, viewing saved QR codes).
1.5. Analytics Permission
This App uses permissions related to Google Play Services for product optimization, with no advertising purposes:
Permission Names: com.google.android.gms.permission.AD_ID, android.permission.ACCESS_ADSERVICES_ATTRIBUTION, android.permission.ACCESS_ADSERVICES_AD_ID, com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE
Purpose: Used solely for in-app event tracking and user behavior analysis to help us improve product features and user experience.
Data Processing: All analytical data is anonymous statistical information, does not contain any personally identifiable information, and is not used for advertising or marketing purposes.
1.5.1. Privacy Protection Commitment
Data Localization: Most features are completed locally on the device, and user private data is not uploaded.
Minimum Necessary Principle: Only requests permissions essential for functionality, does not over-request permissions.
User Right to Know: Clearly prompts the user before using features that require permissions.
Transparency: All permission usage has a clear business purpose and will not be used for other purposes.
No Advertising Purpose: Google Play Services-related permissions are used only for data analysis and are not used for any advertising or personalized recommendations.
1.5.2. Special Notes
The App does not collect, store, or share users' personally identifiable information. All scanned and created QR code content is processed locally unless the user explicitly chooses to share or save it. We are committed to protecting user privacy and ensuring the App complies with the privacy policy requirements of the Google Play Store.
Google Mobile Services (GMS) are used only for in-app event tracking and user behavior analysis, and are not involved in advertising or personalized ad recommendations. We use this analytical data only to improve product features and user experience.
Note: Some permissions may only be requested on specific devices or Android versions; the actual situation shall prevail.
1.6. Information Collected by Third-Party Services
This App may use third-party services (for example, analytics tools), and these services may collect your information according to their own privacy policies. We recommend that you review the privacy policies of these third-party services. The following are examples of third-party services that may be used by this App:

Providing Customer Support: Responding to your inquiries, feedback, or complaints (such as replying to questions via the email you provided).
Fulfilling Legal Obligations: Complying with applicable laws and regulations, Google Play Store policies, and legitimate requests from judicial authorities (such as providing necessary information when cooperating with an investigation).
3.How We Share Your Information
We strictly control the scope of information sharing and will only disclose your information in the following necessary circumstances, while ensuring that the recipient complies with privacy protection obligations:
Sharing with Third-Party Service Providers: Information is shared only with service providers that provide us with technical support (such as Google Analytics for Firebase for data analysis, and server hosting providers for App operation). These service providers can only access the information within the scope of their services and are required to keep the information confidential and not use it for other purposes.
Disclosure Based on Legal Requirements: Information may be disclosed upon receipt of a court subpoena, a legitimate government directive, or to fulfill a legal obligation, enforce the App's terms of service, or protect our and users' legitimate rights and interests (such as preventing fraud).

4. Your Rights and Choices
You have the following control rights over your personal information, which can be exercised through the corresponding methods:
Access and Correction: You can access and directly modify or delete the information you have created or saved (such as QR code images) through the in-app settings.
Withdrawal of Permissions and Consent: You can turn off permissions such as the camera and storage through your device's system settings (e.g., "App Management - Permissions"). If you withdraw your consent for information processing (such as location information collection), we will stop collecting the relevant information, but this will not affect the information processing that was lawfully authorized before the withdrawal.
Deletion of Personal Information: You can contact us to request the deletion of your communication records and account-related information (if any). However, please note that some information (such as App operation logs) may need to be retained due to legal requirements or service necessity.
Opt-out of Personalized Ads: You can choose to opt out of personalized ads through your device settings or by referring to the policies of the advertising service provider.
5.Data Security
We take industry-standard security measures to protect your information and prevent unauthorized access, disclosure, modification, or damage:
Data Localization: The core data of this App (such as scanned content and generated QR codes) is stored and processed locally on your device and is only transmitted over the network when you actively choose to use the "share" function.
Minimum Necessary Principle: Only permissions essential for App functionality are requested, and no additional permissions unrelated to the functionality are requested.
Special Note: Internet transmission or electronic storage methods cannot be 100% secure. We cannot guarantee the absolute security of information in extreme situations (such as hacker attacks). In the event of an information security incident, we will promptly notify you in accordance with the law and take remedial measures.
