Terms of Service

LumenQR provides free browser-based tools for creating static QR codes and barcodes, customizing and downloading generated images, and scanning codes with a camera or local image. These tools generally process entered content in your browser and do not require an account.

LumenQR also provides an account-based Dynamic QR early-access service for creating and managing live dynamic QR codes. Each dynamic QR code encodes a LumenQR short link that temporarily redirects scanners to the destination URL you store. You can update the destination, pause, resume, or permanently archive a code from the dashboard.

The native destination types (PDF, image gallery, video, social links, app, menu, event, coupon, and feedback) are hosted by LumenQR: the short link redirects scanners to a page LumenQR serves from the content and files you provide. You are responsible for that content and must have the rights to share every file you upload. Uploaded files are stored privately and delivered through same-origin proxied links that never expose storage object paths while a code is live; content and file size limits are enforced as documented, and the same prohibited-use rules apply to hosted pages as to linked destinations.

The Dynamic QR feature is in early access, free, and subject to change. Codes go live when they are created: the encoded short link issues a temporary (302) redirect to your current destination and does not itself contain your content. Features, schemas, safety checks, limits, and stored records may change or be discontinued as the service develops. We may apply rate limits, storage limits, or other controls, and may restrict or suspend access to codes or accounts when reasonably necessary to protect the service, address abuse, or enforce these Terms.

Destination URLs must pass strict deterministic structural validation: only public HTTP and HTTPS URLs are accepted, and local names, IP addresses, embedded credentials, fragments, and non-default ports are rejected. This validation is structural only — LumenQR does not check destinations against third-party malware or reputation databases and does not guarantee that any destination is safe.

You can pause a live code at any time, which stops its redirect until you resume it. Archiving a code is permanent: the redirect stops immediately, archived records cannot be restored through the service, and the record and short code remain reserved so a code that may already have been printed or distributed is never reassigned to an unrelated destination.

You are responsible for verifying every destination and generated image before use or distribution. A printed dynamic QR code permanently encodes its short link; only the destination behind that link can change.

The service, including early-access features, is provided "as is" and "as available." To the extent permitted by applicable law, LumenQR disclaims warranties of uninterrupted availability, fitness for a particular purpose, accuracy, non-infringement, and error-free operation.

QR codes, barcodes, scanners, destinations, printers, cameras, and third-party readers can behave differently. You must test outputs in the environment where they will be used and maintain an appropriate backup of important data.

For questions about these Terms, use the feedback page (/feedback). Sending feedback requires a signed-in account and is protected by abuse-prevention checks and rate limits. We never store your raw IP address, user agent, or device data — only a pseudonymous anti-abuse HMAC derived from your IP address, kept for up to 180 days. Do not submit passwords, authentication links, access tokens, or other secrets.

Feedback you send is private by default. Only if you explicitly allow anonymous publication may an approved message be shown publicly, always under Anonymous; your email address and account details are never published. LumenQR may decline or withdraw publication at its discretion, and you may ask us to withdraw a published message through the same page.
