QR Code Scan Privacy Policy
By downloading, installing, or using the "QR Code Scan" app (hereinafter referred to as the "App"), you acknowledge that you have carefully read, fully understood, and agree to the entire terms of this Privacy Policy. This Policy explains how we collect, use, store, and protect your personal information, and explains your rights with respect to that information. If you disagree with any of the terms in this Policy, please immediately cease using the App.
Data Collection Scope and Methods
Necessary Functional Data
To enable the core QR code scanning functionality, this App requests access to your device's camera. Temporary data generated during the scanning process (including parsed content such as the text and URL contained in the QR code) is processed only locally on your device.
Extended Functionality Data
Album Access Data: When you select an image containing a QR code or barcode from your device's photo album for recognition, we request permission to access the photo album to read the target image data in the album for analysis. If you deny this permission, only the "Scan QR Code from Photo Album" feature will be unavailable; the camera's direct scan feature will still function normally.
You can disable these permissions at any time in your device settings.
Automatically Collected Information
Device Information
To ensure the proper operation of the app, maintain security, and optimize services, we collect basic device information, including:
Device model, operating system version; device identifiers (de-identified and used only to uniquely identify the device and not linked to personally identifiable information); and application version number.
Log Data
When you encounter program errors, crashes, or other anomalies while using the app, we will use third-party technical tools to collect log data locally on your device to locate the cause of the problem. Log data may include: device Internet Protocol (IP) address; device name, operating system version; application configuration information, error codes; the time and date of the anomaly, and related operation records; and other non-identifying statistical data.
Anonymized Data Processing
When your information is processed through de-identification and anonymization technologies and cannot be traced or linked to your personal identity by any reasonable means, it will no longer be considered "Personal Information."
We may retain this anonymized data for a long period of time, regardless of the personal information retention period. This data is used solely for the following purposes: analyzing user behavior trends to optimize product features, assist in product development decisions, conduct market research, and improve the service experience. It will not be used to identify or associate any specific individual.
Data Use Purpose
The information we collect is used solely for the following purposes:
Providing and optimizing core and optional service features such as QR code scanning and creation;
Ensuring application security and stability, and troubleshooting and remediating program issues;
Measuring user usage habits, device distribution, and feature usage frequency to improve the product experience; and
Complying with legal and regulatory information retention obligations.
User Rights
We fully respect your right to control your personal data. If you are located in the EU, you have the following rights related to your personal data under the General Data Protection Regulation (GDPR):
Right of Access: You have the right to request access to your personal data we have collected and obtain a complete copy of such data.
Right to Correction: If you discover that your personal information held by us is incomplete, inaccurate, or outdated, you have the right to request that we correct it. We will promptly update the data after verifying its authenticity.
Right to object to processing: You may exercise this right in two situations: first, if we process your personal data based on legitimate interests and you have specific, legitimate grounds for objecting; and second, if you object at any time to our use of your personal data for any marketing activities, without providing additional justification.
Right to erasure (also known as the "right to be forgotten"): If we no longer have a legitimate basis to retain your personal data (e.g., no longer having a business need or the expiration of a storage period), you have the right to request that we delete all relevant data. We will promptly delete the data after verifying that the conditions for deletion have been met and will notify you of the results upon request.
Right to data portability: You have the right to request that we provide your personal data in a structured, commonly used, and machine-readable format (e.g., CSV) so that you can transfer it to another service or data processor. This right only applies to two types of data: automated data that you have actively consented to, and data generated during the performance of a contract related to our services. Right to Withdraw Consent: You may withdraw your prior consent for the processing of your personal data at any time. However, please note that, upon withdrawing your consent, features that relied on that consent may not function properly. Furthermore, such withdrawal does not affect the lawfulness of any data processing we performed based on your consent prior to your withdrawal.
You may submit a request to exercise your rights to us using the contact email address provided at the end of this Policy.
To protect the security of your personal information and prevent others from impersonating you to claim rights, we may require you to provide reasonable identity verification documents before processing your request. We will respond to your valid request promptly, in accordance with GDPR requirements and within a reasonable timeframe, and will inform you of the progress of the processing if necessary.
If you object to our processing of your personal data or believe we have not responded to your request in accordance with the law, you have the right to lodge a complaint with your local data protection authority. Specific complaint channels can be found on the official websites of the data protection authorities in each European Economic Area (EEA) member state.
Use of Cookies
Cookies are files containing a small, anonymous unique identifier. They are sent to your browser from the service pages associated with this app and stored in your device's memory. This app and its partnered third-party libraries (such as Google Analytics) may use cookies to implement the following functions:
Remembering usage preferences
Optimizing the service experience
You can choose to accept, reject, or delete cookies through your device browser settings. Please note: If you choose to reject cookies, some features may not function properly, but the core scanning function will not be affected.
Data Sharing and Third-Party Services
To ensure stable app operations, optimize the functional experience, and provide personalized services, we may collaborate with third parties and share relevant data under strict compliance regulations. The details are as follows:
Advertising Partnerships and Data Sharing
We work with advertising service partners (such as Pangle, Google Admob, and Topon) and only provide them with de-identified information, including basic device parameters and app usage data. The above information has been stripped of any personally identifiable information and is used solely to help advertising partners analyze user habits and interests to deliver more relevant advertising. Your sensitive personal information will not be used.
How to opt out of ad personalization: You can opt out of interest-based targeted advertising at any time through your device settings. The specific paths are as follows: Android devices: Enable "Opt out of interest-based ads" or "Opt out of ads personalization" in system settings;
iOS devices: Enable "Limit Ad Tracking" in privacy settings.
Note: This will stop the app from using your behavioral data to generate personalized ads, but you may still receive non-targeted, generic ads.
Third-Party SDK Services
This app integrates necessary third-party SDKs to enable basic functionality or data analysis. The functions and data processing rules of these SDKs are as follows:
Firebase Analytics: Used for statistics and analysis of app usage. All data is anonymized and not linked to personally identifiable information.
Google Play Services: Provides basic app functionality and only processes the data necessary to implement functionality.

Data Sharing Based on Legal Requirements
In addition to the aforementioned cooperation scenarios, we may share your information only under the following legal circumstances and strictly adhere to the "minimum necessary" principle. Principles:
Responding to Requests from Authorized Authorities: We will provide information within the legally necessary scope based on legitimate documents from legally authorized authorities such as courts, procuratorates, and administrative law enforcement agencies.
Protecting Legal Rights and Interests: We will share relevant information within a reasonable and necessary scope to protect the legitimate rights and interests of us, you, or third parties in emergencies such as fraud, security attacks, and infringements of user rights.
Data Security and Retention
Data Security Measures
We prioritize the security of your personal data and implement multiple protections throughout the entire process, from transmission to storage and management. These include:
Information Transmission Security: We use industry-standard encryption protocols (such as SSL/TLS) to encrypt data transmission to prevent unauthorized interception, tampering, or theft during transmission.
Technical Security: We utilize technical measures such as encrypted data storage and regular vulnerability scanning to prevent cyberattacks, data leaks, and other risks, ensuring a secure data storage environment.
Management and Control: We maintain a strict data access rights system, authorizing only essential personnel to access specific data.
While we have established a comprehensive security system, we must objectively acknowledge that the internet environment and technology inherently carry inherent risks; no data is completely secure. Therefore, when using this service, you fully understand and voluntarily assume the aforementioned inherent risks. We assume no liability for security issues caused by factors beyond our reasonable control.
Data Retention Period
We strictly adhere to the "minimum necessary" and "minimum retention" principles, retaining your personal information only for as long as necessary to achieve specific, explicit, and legitimate purposes. The specific retention period depends on service operational needs and legal obligations.
Links to Other Websites
Our applications or service pages may contain links to third-party websites, applications, or services (such as partner pages and third-party tool portals). Please note: These third-party platforms are independently operated and managed by us. We have no control over their content updates, privacy policies, or data processing practices, and we are not responsible for their information security, operational legality, or data protection measures.
When you access third-party links, you are responsible for complying with the platform's user agreement and privacy policy. We recommend that you carefully read their privacy policies before providing any personal information to third parties to fully understand their data collection, use, sharing, and protection practices. Any disputes, information leaks, or financial losses arising from the use of third-party websites or services will be resolved between you and the third party, and we assume no liability.
Children's Privacy Protection
This app is not intended for children under the age of 13, and we expressly prohibit the collection of personal information from minors. If, under unusual circumstances, we accidentally collect information from children under the age of 13, we will verify the situation and immediately delete the relevant data upon discovery or notification by their guardian. If you have any questions, please contact us at [email protected].
