Privacy Policy

App Name: QR Code Scanner Barcode Reader
Last Updated: November 5, 2026

1. Introduction

Welcome to QR Code Scanner Barcode Reader ("we," "our," or "us"). We respect your privacy and are committed to protecting your personal information. This Privacy Policy explains what information the App processes, how it is used, and how it is protected.

QR Code Scanner Barcode Reader follows a Local-First design. Your scanned codes, created codes, history, favorites, and settings are stored and processed on your device. We do not operate a server that stores, reads, or sells your scanned or created codes. The App does not require an account or sign-in.

Limited technical, advertising, and installation-record data may be processed by third-party service providers and our servers, as described in Sections 2.2 and 5.

2. Information We Collect

2.1 Data Processed Only on Your Device

To provide scanning and code-creation features, the App processes the following information locally on your device:

Camera Preview: With your permission, the App uses your camera to scan QR codes and barcodes. Camera frames are analyzed in real time on your device and are not saved, recorded, or uploaded.
Images You Select: When you scan a code from your gallery, the App accesses only the image you select through Android's photo picker. The image is not copied, stored, or uploaded by the App.
Scan and Creation History: The content of scanned or created codes (such as links, text, Wi-Fi details, contact cards, or payment requests), code format, source (camera, gallery, or created), date and time, and favorite status are stored in the App's private local database. You can disable Save History in Settings.
Codes You Create: The information you enter to generate a code is processed on your device. If you select Save to Gallery, the generated code image is saved to your phone's Pictures folder. If you select Share, a temporary image is created for sharing with the application you choose.
Link Safety Check: Links contained in scanned codes are checked for warning signs directly on your device. These links are not sent to us for this check.
App Settings: Your language, theme, beep sound, vibration, automatic link opening, automatic copying, batch scan defaults, and history-saving preferences are stored locally.

2.2 Automatically Collected Data (Not Your Scans)

The App may process limited technical information for advertising and installation counting.

Advertising Data: Ad requests, impressions, clicks, ad formats, ad placements, and advertising network details may be processed to display advertisements and measure their performance, as explained in Section 5.
One-Time Installation Records: When you open the App for the first time after installation, an installation record is sent to our servers. It contains a randomly generated installation ID, a one-way hashed device key from which the original device ID cannot be recovered, platform (Android), App package name and version, Android version, device model, and time zone.
These records do not contain your name, scanned codes, created codes, contacts, phone number, or location. Each record is sent once and is retried during a later launch only if the initial attempt does not reach the server.

We do not use analytics or crash-reporting services. Through the App's described functionality, we do not directly collect your name, email address, contacts, precise location, photos, or files. Third-party service providers may independently process information as explained in Section 5.

3. How We Use Your Data

We use the information processed by the App for the following purposes:

Scanning: To read QR codes and barcodes using your camera or a selected image and display the information contained in them.
Actions on Scan Results: To let you open links, copy text, call or message a number, send emails, add contacts or calendar events, open locations in a maps application, add Wi-Fi networks, or open UPI payment applications. These actions occur only when you tap the relevant option. The App passes the selected information to the application or Android screen you choose. The App does not process payments.
Creating Codes: To generate, customize, save, and share QR codes and barcodes.
History and Favorites: To display, search, and organize your previous scans and created codes.
Home Screen Widget and Quick Settings Tile: To provide quick access to the scanner. These features do not display or store your scanned codes.
Advertising: To display advertisements that help keep the App free and measure their performance.
Installation Counts: To count App installations through one-time installation records.

4. Permissions Required and Why We Need Them

The App may request or use the following Android permissions:

CAMERA: Used to scan QR codes and barcodes. Camera frames are processed on your device and are not saved or uploaded.
VIBRATE: Provides a short vibration when a code is scanned, if vibration is enabled in Settings.
WRITE_EXTERNAL_STORAGE (Android 9 and Earlier Only): Used to save generated code images to your Pictures folder when you select Save to Gallery. Newer Android versions do not require this permission.
INTERNET and ACCESS_NETWORK_STATE: Support advertising and one-time installation records. Scanning and creating codes work without an internet connection.
AD_ID (Advertising ID) and Android Ad Services Permissions: Support advertising and ad measurement through Google AdMob, as explained in Section 5.
WAKE_LOCK and FOREGROUND_SERVICE: These permissions are included by Google's advertising library for its internal use. The App does not operate its own background service.

Scanning images from your gallery uses Android's photo picker and does not require storage permission.

When you choose to add a contact, calendar event, or Wi-Fi network, the App opens the relevant Android or application screen for your confirmation. The App does not request contacts, calendar, or Wi-Fi permissions for these actions.

You can review or revoke available permissions at any time through your device's Settings.

5. Third-Party Services and Advertising

To keep the App free, we use third-party services. Each provider processes information according to its own privacy policy and applicable settings.

Google AdMob: May process device identifiers, including the Google Advertising ID (GAID), device brand and model, operating system version, approximate location at country or city level, network connection status, and advertising interaction data to display and measure advertisements and help prevent fraud.
Meta Audience Network: Advertisements may also be provided by Meta Audience Network through AdMob mediation. Meta may process similar device and advertising interaction information to deliver and measure advertisements.
Google User Messaging Platform (Consent): Users in the European Economic Area (EEA), the United Kingdom, and Switzerland are asked to provide their advertising consent when they first open the App. No advertisement is requested before this choice is made. Your consent choice is stored on your device.
Google ML Kit: QR codes and barcodes are scanned on your device using Google's ML Kit library. Your images are not sent to Google. ML Kit may send Google limited technical information about the library's performance.
Our Installation Tracking Servers: Receive the one-time installation records described in Section 2.2.
Other Applications You Open: When you choose actions such as opening a link, calling, messaging, emailing, viewing a map, adding a contact or event, making a UPI payment, or sharing content, the App opens the application you select. The App passes only the code content necessary for the action you choose.

6. Data Storage, Retention, and Security

Local Storage: Your scan history, favorites, and settings are stored in the App's private storage on your device, which other applications cannot access through ordinary app access. Code images you save to your gallery are stored in your phone's Pictures folder like other photos.
No Cloud Storage of Your Scans: We do not upload, back up, or retain copies of your scanned or created codes on our servers.
Android Backup: If Android backup is enabled for your Google account, Android may include the App's history and settings in your device backup. This backup is managed by Google under your account, and we cannot access it.
Data Retention: Your local data remains on your device until you delete it or uninstall the App. Advertising data is retained by the relevant third-party providers according to their own retention policies.
Security: Information sent to our advertising partners and installation tracking servers is transmitted through encrypted connections (HTTPS).

Although we take reasonable steps to protect information handled by the App, no method of electronic transmission or storage can be guaranteed to be completely secure.

7. User Control and Data Deletion

You have control over your information and how you use the App through the following options:

History Control: Delete individual history entries or disable Save History in Settings to prevent new scans from being saved.
Feature Control: Turn sound, vibration, automatic link opening, and automatic copying on or off through Settings.
Saved Images: Delete generated code images saved to your gallery through your phone's Gallery or Photos application.
Delete Local App Data: Use Clear Data in your phone's App Settings or uninstall the App to remove locally stored App data.
Permission Control: Review or revoke App permissions through your phone's Settings.
Advertising Control: Reset your Advertising ID or opt out of personalized advertising through your device settings, where available. Where advertising consent applies, you can change your choice through Settings → Privacy Options in the App.

Deleting App data does not delete information that has already been processed or retained by third-party service providers. Such information remains subject to their respective retention and deletion policies.

We do not knowingly collect personal information from children under 13 through the App's described functionality.
