QR Visualizer does not collect, store, transmit, sell, or share personal data. The app does not require an account and does not use analytics, advertising SDKs, crash reporting SDKs, or a custom backend server operated by me.
If you choose an image or take a photo, the selected image is processed locally on your device to run the QR decoding visualization. The image is not uploaded to my servers and is not shared with me.
Camera or photo access is requested only when you choose an app action that needs it, such as selecting a QR image or taking a QR photo.
Decoded QR content is shown inside the app. QR Visualizer does not send decoded content to me or to a server operated by me.
QR Visualizer does not intentionally integrate third-party services that collect user data for analytics, advertising, tracking, crash reporting, or user accounts.
Because QR Visualizer does not collect personal data, there is no personal data for me to sell, rent, or share.
QR Visualizer does not retain personal data on my servers. Any app data stored locally on your device can be removed by clearing the app data or uninstalling the app.
QR Visualizer is a general-audience educational app. It is not specifically directed to children, and it does not knowingly collect data from children.
This policy may be updated from time to time. The current version will be available on this page.
