# Disclaimer > Disclaimer: what QR Code Builder guarantees and what it does not — scanning reliability, print outcomes, general guidance, links and trademarks. Source: https://qr-code-build.com/disclaimer/ Last reviewed: 2026-08-24 Publisher: QR Code Builder ## Summary QR Code Builder provides its generator and guides without warranty. Codes are produced by a standards-compliant encoder, but we cannot guarantee any particular code will scan on a given device, printer or material — that depends on size, contrast, substrate and lighting, which is why every page tells you to test before printing. ## We cannot guarantee a code will scan The generator implements ISO/IEC 18004 and produces structurally valid codes. Whether a specific printed code scans in the real world depends on factors entirely outside this website: - The physical size it is printed at, and the resulting module size. - Contrast between the modules and the background once converted to CMYK and put on press. - The substrate — coated card, uncoated kraft, film, fabric and metal all behave differently. - Ink spread, print registration and finishing. Gloss lamination in particular causes reflection failures. - The scanning device, its camera quality, and the ambient lighting. - Damage, wear, curvature and viewing angle after the code is deployed. This is why every relevant page on this site says the same thing: print a proof at final size, on the final material, and scan it with at least two different phones before committing to a run. That check is your responsibility, and it is the single most effective way to avoid an expensive reprint. The [failure diagnosis guide](/learn/why-qr-codes-fail-to-scan/) covers what to look at when something does not work. ## What you encode is yours, and yours to verify We never see the contents of the codes you generate — encoding happens in your browser. That also means we cannot check them for you. You are responsible for verifying that: 1. The encoded destination is correct, character for character. Decode your own exported file and read it back. 2. Payment details, account numbers and reference codes are exactly right. Some transactions cannot be reversed once made. 3. The destination remains live for as long as the printed material is in circulation. 4. The content and destination comply with the law and with any platform rules that apply where the code is used. The [reader](/qr-code-scanner/) exists partly for this: it decodes your own exports so you can confirm the payload before printing. ## General information, not professional advice The guides on this site describe general practice in print production and QR code deployment. They are written from experience and checked against the specification, but they are not advice for your specific job, jurisdiction or circumstances. - **Print specifications** vary by press, substrate and finisher. Confirm sizes and tolerances with your printer. - **Legal and regulatory points** — including data protection, consumer disclosure requirements and sector rules such as GS1 or pharmaceutical labelling — are summarised only. Take proper advice before relying on them. - **Platform behaviour** changes. How a given phone, app or store handles a payload can change with any update, and our descriptions may lag behind. - **Nothing here is legal, financial, medical or regulatory advice.** ## Links, services and names This site links to and describes external services — Google Business Profile, WhatsApp, the App Store, Google Play, cloud storage providers, open-source libraries and others. We do not control them, are not responsible for their content, availability, pricing or policies, and describing them is not an endorsement.

Despite that, information may become out of date or contain errors. We make no representation that the site is complete, current or error-free, and we may change or remove content at any time. If you find something wrong, tell us — corrections are made and credited, and the page's review date is updated. Liability is addressed in the [terms of use](/terms/), which apply alongside this page. ## Frequently asked questions ### Do you guarantee that my QR code will scan? No. The encoder produces valid, standards-compliant codes, but real-world scanning depends on print size, contrast, material, finish and the reading device. Always proof at final size before a print run. ### Who is responsible if a print run fails to scan? You are. We cannot inspect your artwork, your press or your material. Proofing at final size on the final substrate is the check that catches this, and it takes minutes. ### Is the guidance on this site professional advice? No. It is general information based on print production experience. For your specific job, jurisdiction or regulatory situation, take proper professional advice. ### Are you affiliated with Denso Wave? No. QR Code is a registered trademark of DENSO WAVE Incorporated, used here descriptively to refer to the published standard. --- Licence: this page may be quoted with attribution to QR Code Builder (https://qr-code-build.com/disclaimer/).
