QR Scanner – Privacy Policy

App: QR Scanner (Android package com.devvu.codescanner) · Developer: Devvu Apps · Effective date: 27 October 2026

This policy explains what information the QR Scanner app ("the app", "we") handles, why, and the choices you have. It applies to the app as distributed on Google Play.

In short

Codes are read on your phone. What you scan or create is never sent to us.
Your scan history stays on your phone, and you can switch it off or delete it.
The app uses Google services for usage statistics, crash reports and ads. They receive technical information about your device, never the content of your codes.
You don't need an account, and we don't sell personal information.

1. Information that stays on your phone

Camera images. The camera image is processed on your device to find and decode codes. Images are not saved or uploaded.
Photos you choose. When you scan a code from your gallery or add a logo to a QR code, only the photo you pick is read, on your device. The app uses the system photo picker and does not get access to your other photos.
Scan and creation history. Codes you scan or create, with their date and any favourites or notes, are kept in a database inside the app on your phone. It is not backed up to our servers or to Google Drive by the app. You can turn history off, use incognito scanning, or delete entries at any time.
Settings such as theme, language, sound and vibration are stored on your phone.

2. Permissions the app asks for

Permission	Why it is used
Camera	To scan QR codes and barcodes.
Contacts	Only when you tap "Save contact" on a scanned contact card, to add that contact to your phone. The app does not read or upload your existing contacts.
Calendar	Only when you tap "Add to calendar" on a scanned event, to add that event. The app does not read or upload your calendar.
Internet	For usage statistics, crash reports and ads (section 3), and to open links you choose.
Vibration	To give haptic feedback after a scan (can be turned off in Settings).

Saving an exported QR code to your gallery uses the system's media storage and only writes the image you chose to save.

3. Information collected by Google services

The app includes the following services provided by Google. They collect information automatically to provide their service. None of them receive the text, links, contact details, Wi-Fi passwords or other content of the codes you scan or create.

Service	What it collects	Purpose
Google Analytics for Firebase	App interactions such as screens viewed, the type and format of codes scanned (for example "URL" or "QR"), which features are used, and the app language; plus an app-instance identifier, device model, operating system version, app version and approximate region.	To understand how the app is used and improve it.
Firebase Crashlytics	Crash and error reports: stack traces, device model, operating system version, app version, an installation identifier, and short technical notes such as why the camera failed to start.	To find and fix crashes and bugs.
Google Mobile Ads (AdMob)	Advertising ID, IP address, device and app information, and ad interactions.	To show ads, which are shown only after you export a QR code that you created, and to measure and limit them.

Google processes this information under its own policies: Google Privacy Policy, Firebase privacy and security and how Google uses information from apps that use its services. Information is transferred to and stored on Google's servers, which may be outside your country.

4. Retention

Information on your phone is kept until you delete it or uninstall the app. Information collected by Google services is kept according to Google's retention settings for each service. Crashlytics keeps crash reports for up to 90 days.

5. Your choices

Turn off history, use incognito scanning, or delete history entries in the app.
In the EEA, the UK and Switzerland, the app asks for your consent before ads are personalised. You can change your choice at any time in Settings › Ad privacy choices.
Reset or delete your advertising ID, or opt out of personalised ads, in your phone's settings (Settings › Privacy › Ads, or Settings › Google › Ads).
Uninstalling the app deletes everything it stored on your phone.
To have your data deleted, see section 6.

6. Deleting your data

QR Scanner has no accounts, so most of your data can be deleted by you directly:

On your phone: delete entries in History (select them and tap Delete), or uninstall the app, which removes your whole scan history and all settings.
Usage statistics and crash reports are not linked to your name, email or any account. Crash reports are deleted automatically after 90 days, and usage statistics after at most 14 months.
Advertising data: reset or delete your advertising ID in your phone's settings so it can no longer be connected to earlier ad activity.
To ask us to delete data, email sreedhu0714@gmail.com with the subject "QR Scanner data deletion". We delete any data we can associate with you and reply within 30 days.

7. Links and actions you open

When you open a scanned link, call a number, send an email or join a Wi-Fi network, that action happens in another app or website with its own privacy policy. The app's link check runs on your phone and does not send the link anywhere.

8. Children

The app is not directed at children under 13, and we do not knowingly collect personal information from children.

9. Security and changes

We rely on Android's app sandbox and Google's security measures to protect information. If this policy changes, the updated version will be published in the app and on its Google Play listing with a new effective date.
