About QR Studio

QR Studio is an offline-first QR code generator and scanner app. The app generates, customises, and scans QR codes entirely on your device. QR Studio does not send your QR content to a backend server.

The app may include ads served by Google Mobile Ads and optional Pro features available through in-app purchase. This policy explains what data is handled locally, what third-party services may process, and what choices you have.

Data stored locally on your device

QR Studio may store the following data locally on your device:

• Your selected QR type and content (URL, text, contact, Wi-Fi, and so on)
• Style and customisation preferences (colours, logo, pattern)
• QR code history if you enable history within the app
• Local unlock or purchase state for Pro features
• App settings and preferences

How QR codes are generated and scanned

QR codes are generated on-device using local processing. The content you encode — such as a URL, phone number, Wi-Fi password, or text — does not leave your device during generation.

When you scan a QR code using the app's camera, the decoded content is displayed on your device. Scanned content is not automatically transmitted to QR Studio or any third party.

Exporting and sharing QR codes

When you export or share a QR code image, the app hands the generated file to the operating system share sheet or saves it to your device gallery if you choose Save. QR Studio does not upload exported QR images to its own server.

If you share a file through another app, cloud service, messaging service, email app, or printing service, that third-party service may process the file according to its own privacy policy.

Advertising

The free version of QR Studio may display ads through Google Mobile Ads (AdMob). Google AdMob and its partners may collect or process data such as:

• Device advertising ID
• IP address and approximate location
• App activity related to ad display and ad performance
• Device model, operating system, app information, diagnostics, and performance data

This data may be used for ad delivery, ad measurement, fraud prevention, frequency capping, and related advertising purposes. You can manage ad personalisation through your device settings or Google ad settings where available.

In-app purchases

QR Studio may offer in-app purchases through Google Play, Apple App Store, or other app-store platforms for Pro features such as advanced customisation, batch generation, or an ad-free experience.

Payment processing is handled entirely by the app-store provider. QR Studio does not receive your full payment card details. QR Studio may receive purchase status or licensing information needed to unlock Pro features on your device.

Device permissions

QR Studio may request the following permissions depending on the feature and device platform:

• Camera — to scan QR codes using your device camera
• Storage / Media — to save generated QR code images to your gallery
• Internet / Network — required for ad delivery by Google Mobile Ads

Third-party services

QR Studio may use the following third-party services. These services process data according to their own privacy policies.

Data retention and deletion

QR content, history, style preferences, and settings are stored locally on your device. You can delete this data at any time by:

• Clearing QR history inside the app where available
• Clearing app data from your device settings
• Uninstalling the app
• Deleting exported QR images from your device gallery or storage

Data processed by third-party services such as Google AdMob or Google Play is retained according to those services' own policies.

Data security

QR Studio uses platform security features for locally stored data. Data transmitted by third-party services such as Google AdMob uses secure transmission methods provided by those services.

Because QR content is processed and stored on your device, you are responsible for protecting your device with a screen lock, password, or other device security controls.

Your privacy choices

Regional privacy rights

Depending on your country or region, you may have privacy rights such as requesting access, correction, deletion, restriction, objection, or portability of personal data processed about you.

Because QR Studio stores data locally on your device and does not operate an online server for QR content, many deletion and correction actions can be performed directly from your device.

Policy updates

We may update this Privacy Policy when the app changes, when third-party services change, or when legal or platform requirements change. When we make changes, we will update the "Last Updated" date at the top of this page.

Continued use of the app after updates constitutes acceptance of the revised policy.
