Privacy Policy
Effective Date: 2026.4.16
QR Reader* (“the App”) is developed and provided by Guido Marc Schumacher (“Developer”, “we”, “our”, or “us”).
This Privacy Policy explains how the App may collect, use, store, and protect information when you use our mobile application.
If you have any questions about this Privacy Policy, you may contact us at:
1. Information We Collect
The App is designed to scan QR codes and barcodes, generate QR codes, and help users manage scanned or created content.
Depending on how you use the App, we may process the following types of information:
a. Camera Access
The App may request access to your device camera in order to scan QR codes and barcodes.
We do not use camera access for any purpose other than enabling scanning functionality.
b. Photos / Media / Files Access
If supported by your device or Android version, the App may request access to photos, media, or files so that you can:
- import images containing QR codes or barcodes for scanning
- save generated QR codes to your device
- export or share scan results
c. Scan Content
When you scan or create a QR code, the content may include text, links, contact details, Wi‑Fi information, phone numbers, email addresses, or other data encoded by you or contained in the scanned code.
Unless otherwise stated, this content is processed locally on your device for core app functionality.
d. App Usage Data
We may collect limited technical or diagnostic information such as:
- app version
- device type
- operating system version
- crash logs
- performance data
This information may be used to improve app stability, security, and performance.
e. Advertising and Analytics Data
If the App uses third-party analytics or advertising services, those services may collect certain information automatically, such as:
- advertising ID
- device identifiers
- app interaction data
- approximate location inferred from IP address
- diagnostics data
Please note that such data collection is subject to the privacy practices of the relevant third-party providers.
2.How We Use Information
We may use information for the following purposes:
- to provide QR code and barcode scanning features
- to generate and save QR codes
- to display scan history or created code history on your device
- to improve app performance, reliability, and user experience
- to fix bugs and monitor crashes
- to ensure security and prevent misuse
- to support advertising or analytics, where applicable
3.Local Processing and Storage
Many core functions of the App work locally on your device.
Scan results, generated QR codes, and history may be stored locally on your device so you can access them later.
You can usually delete this information within the App or by clearing the App’s storage from your device settings.
4.Sharing of Information
We do not sell your personal information.
We may share information only in the following cases:
- with service providers that help us operate, analyze, or improve the App
- with advertising or analytics partners, if such services are used
- when required by law, regulation, legal process, or governmental request
- to protect the rights, safety, or property of users, the Developer, or others
5.Third-Party Services
The App may use third-party tools or services, such as analytics, crash reporting, or advertising SDKs.
These third parties may collect and process data in accordance with their own privacy policies.
Examples may include:
- Google Play Services
- Google AdMob
- Firebase Analytics
- Firebase Crashlytics
If your App uses any of the above or similar services, their data practices may apply in addition to this Privacy Policy.
6.Data Retention
Information stored locally on your device remains on your device until you delete it or uninstall the App.
Diagnostic, analytics, or advertising-related data may be retained for as long as reasonably necessary for the purposes described in this Privacy Policy, or as required by applicable law and third-party service providers.
7.Security
We take reasonable measures to protect information and reduce the risk of unauthorized access, disclosure, alteration, or destruction.
However, no method of electronic storage or transmission is completely secure, and we cannot guarantee absolute security.
8.Children’s Privacy
The App is not directed to children under the age of 13, and we do not knowingly collect personal information from children under 13.
If you believe that a child under 13 has provided personal information through the App, please contact us at [email protected], and we will take reasonable steps to address the issue.
9.Your Rights and Choices
Depending on your location and applicable laws, you may have certain rights regarding your information, including the right to:
- access certain information
- request deletion of certain information
- withdraw permissions (such as camera or storage access) through your device settings
- limit certain data processing where applicable
You may also:
