➤ Data & Privacy Security

We value the importance of data privacy. This new version of the extension is built using pure front-end technology. All your QR code generation and decoding happen entirely within your local browser environment—your data never gets uploaded to any server.

This extension does not collect, store, or transmit any specific QR code content or decoding results. Only anonymized statistical data (such as “number of QR codes generated”) is collected to optimize the extension. Your data is 100% yours.
