Privacy Policy | QRCodeAB

Last updated: September 8, 2026

This Privacy Policy explains how QRCodeAB handles information when you use this website, including how the browser-based QR generator and scanner work.

1. QR Generation and Scanning

QRCodeAB creates and decodes QR codes on your device in your web browser using JavaScript. QR content, uploaded images, camera frames, and decoded results are not sent to, stored on, or accessible by our servers.

2. Anonymous Usage Telemetry (Optional)

To understand which features are popular, QRCodeAB can record privacy-first counts such as page views, QR codes created per content type, download formats, and scan modes. These events contain no QR payloads, no images, and no raw IP addresses. Visitors are anonymized with daily rotating salted hashes. You can disable this in the admin analytics settings.

3. Contact Form Information

If you contact us, we collect the information you choose to provide, such as your name, email address, subject, and message. We use it to respond to your request and help operate and secure the website. Do not submit Wi-Fi passwords or other sensitive credentials through the contact form.

4. Server Log Files

Like most websites, QRCodeAB and its hosting providers may maintain standard server logs (IP address, browser type, timestamps, referring pages) to operate and secure the site. These logs are not used to reconstruct QR content.

5. Cookies and Advertising Technologies

QRCodeAB may use cookies or similar technologies to remember preferences, understand site use, and support advertising. Third-party advertising providers may also use cookies, JavaScript, or web beacons to measure performance or personalize ads.

6. Your Choices

You can block cookies in your browser, use tracker-blocking extensions, or simply disconnect from the internet after the page loads. QR creation and image-based scanning keep working offline once assets are cached.

7. Data Security and Retention

Because all QR generation occurs in your local browser environment, we do not store or transmit your raw QR data. For our optional, anonymous usage telemetry, we employ industry-standard security measures to protect the integrity of our systems. Since we do not collect personal information through the core tool, there is no personal data to retain, modify, or delete.

8. Third-Party Services

We may link to or rely on third-party services, such as analytics providers or hosting platforms, to operate the website. These services have their own privacy policies. We do not sell, rent, or trade any user information to third parties.

9. Children's Privacy

QRCodeAB is designed for general audiences and is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe we have inadvertently collected such information, please contact us so we can promptly delete it.

10. Changes to This Privacy Policy

We reserve the right to update this Privacy Policy at any time to reflect changes in our practices or for other operational, legal, or regulatory reasons. We will notify you of any material changes by updating the "Last updated" date at the top of this page. We encourage you to review this policy periodically.
