Every scan of a sticker passes through 'qr.seeqr.de', gets logged with the campaign parameters. You're then forwarded to the awareness page in milliseconds. The dashboard turns that log into the few numbers the team actually needs: total scans since launch, scans today, a rolling week and a rolling month to see whether a print run is still working, and a breakdown per motive and per neighbourhood (by utm parameter on link) to see which sticker draws people in and where. No raw IPs, no cookies, no individual journeys. Just enough to decide where the next batch goes.
