Data Deletion
ProQR has no account and no server, so there is no profile of you anywhere for us to delete. Everything the app stores lives on your own phone, which means you can remove all of it yourself, immediately, without asking us.
Delete everything
Uninstall ProQR. That removes every saved code, your scan history, your settings and your language choice. Nothing survives the uninstall, because nothing was stored anywhere else.
Delete saved codes
Settings → Clear all saved QRs removes the whole workspace at once. To remove one code, open the workspace and use the bin icon on it.
Delete scan history
Settings → Keep scan history, switched off, stops scans being recorded. Existing entries can be removed one at a time, or all at once with Clear, from Scan history in the workspace. The history is kept on the phone only and holds at most the last 50 scans.
Files you downloaded
A PNG saved to Photos, or an SVG, PDF or EPS you shared to another app, is outside ProQR and has to be deleted there.
If you would still like to make a request
Write to proqr@makekk.com. We will confirm what is and is not held — which, for an app with no account and no server, is nothing that identifies you — and act on anything that is.
