aQRnym is a browser extension that finds QR codes on web pages and PDFs you view and shows what each code contains. This policy explains what happens to your data when you use it.
Web pages. To find QR codes, aQRnym looks at the pictures on the pages you visit: images, drawings, and pictures set by a page’s styling. Decoding happens inside the extension on your computer. The codes it finds are kept in your browser’s memory for the tab they were found in, so the extension’s menu can list them. They are deleted when you close the tab or navigate away, and when you close the browser.
Two-factor setup codes (codes for authenticator apps) are never stored. The extension only shows that such a code exists and lets you copy it.
PDFs. aQRnym reads a PDF only when you click “Check this PDF”. It uses the copy your browser already downloaded, reads it inside the extension, and keeps only the QR codes it finds, under the same rules as for web pages.
Screenshots. When you use “Scan this page” or “Select area”, and when a picture on a page cannot be read any other way, aQRnym takes a screenshot of the visible part of the tab to look for QR codes in it. The screenshot is processed on your computer and discarded immediately. It is never saved or sent anywhere.
Two things do:
Requests for pictures. When the page itself is not allowed to share a picture’s contents with the extension, aQRnym asks the website that hosts that picture for it again. This request carries no cookies, so it is not tied to any account you have on that website. That website receives an ordinary request for the picture. It receives nothing about QR codes or anything aQRnym found.
Your settings, through Chrome sync. aQRnym’s settings (whether badges are shown automatically, and the list of websites where you turned them off) are saved with Chrome’s synced storage. If you are signed in to Chrome with sync turned on, Google stores these settings in your Google account so they follow you to your other computers, under Google’s own privacy policy. If sync is off, they stay on your computer.
The “Support aQRnym” link. The extension’s menu and settings page have a link to our website, authenticcoretechnologies.com. It works like any other link: nothing happens until you click it, and then your browser opens that page in a new tab. The extension sends nothing with it. What happens on that website is explained on the website itself.
In the terms Chrome Web Store uses, aQRnym handles the following on your computer only:
aQRnym does not send any of the data above to the developer or to anyone else, so there is nothing to share or sell. The developer has no access to what you browse or what the extension finds.
If this policy changes, the new version will be published at this address with a new date.
