Contact Us
Questions, suggestions, corrections or problems — we answer everything.
The best way to reach us is by email: [email protected]. The site is maintained by one person, so a reply may take a few days — but every message is read.
Before writing: it may already be answered
Most of the messages we get are about the same four situations, and each has a detailed answer somewhere on the site:
- "My QR Code will not scan." It is almost always print size, contrast or an oversized logo. The section on scanning failures on the link QR Code page covers the most common causes.
- "How do I change the link afterwards?" You cannot edit a code once generated, but there is a simple workaround, explained on the link QR Code page.
- "The Wi-Fi QR Code connected with the wrong password." Usually a special character in the password. See the Wi-Fi QR Code page.
- "My name came out truncated in PIX." That is the 25-character limit in the Central Bank specification, explained on the PIX QR Code page.

Missing a QR Code type you need? A customization option that would make a difference in your work? Tell us your concrete use case — the more specific, the better the chance it becomes a priority.
Content corrections
If you found information that is wrong, outdated or badly explained in a guide, let us know. Point to the page and the passage. We fix it and the page shows the new update date.
Privacy and data
To exercise data protection rights or ask about data handling, use the same email. Worth remembering that we do not store the content of the codes you generate — see the privacy policy.
Press and partnerships
Same address. Identify the outlet or company in the email subject.
