Privacy notice
Local processing
QR payloads, generated images, logo files, imported images and batch archives are processed in your browser. QRPier does not upload them or create a hosted redirect. Closing or reloading clears unsaved work; a project you explicitly save remains in this browser until you delete it.
Saved design settings
If you choose Save design, the browser stores the template name, colors, module shape, size, correction level and frame caption in local storage. Payloads and logo images are excluded. You can delete each saved design from the generator.
Saved projects
If you choose Save project, local storage keeps the active QR type, only that type's content, and its settings. It excludes fields left behind by other QR types and excludes logo images. Delete saved projects before leaving a shared device.
Access logs and reports
After server reporting is activated, minimized access records may include the time, a request identifier, an allowlisted page category, method and status, a coarse browser or bot label, and the referring domain. Trusted client addresses are converted immediately into site- and UTC-day-specific HMAC codes; raw IP addresses, full URLs or queries, request bodies, raw browser strings and full referrer URLs are not kept. Owned release checks carry a short-lived marker and are excluded from visitor estimates. During normal scheduled operation, minimized request details rotate daily and are removed within 14 days; a missed cleanup may retain them longer until scheduling is restored. Daily aggregate reports may be kept longer for comparisons, but contain no per-request codes. Visitor estimates are approximate and are not verified people or cross-day identifiers.
Analytics
We show locally hosted image advertiser links. Following a link may share only this site’s origin as the referring address. QRPier does not send QR payloads, decoded values, imported images, filenames, Wi-Fi details or destination URLs to a browser analytics service. We collect limited page, tool-use and ad-view/click events through this site, using a random code kept only in the current tab. Records contain the public page path, referring hostname, operation and campaign identifiers, and server-assigned test/bot categories. They exclude files, filenames, QR contents, typed text, raw IPs, full browser strings and full referring URLs. Detailed event records are normally cleaned daily with about 14 days of retention; interrupted cleanup may delay deletion. Only aggregated counters, without tab, task or ad-instance codes, reach the operations dashboard. Marked owner tests and identified bots, scripts and risk events are excluded from qualified counters; unknown classifications remain separate. Do Not Track and Global Privacy Control disable optional collection. Blocked or failed submissions may reduce counts; sessions are not verified people. Advertising links may carry public source, placement, campaign and creative labels. In this tab, these labels connect arrival counts with tool completion and download initiation. Session, task and ad-display identifiers are not shared between sites.
