How do I send feedback or report a security issue?
Share an idea, report a bug or contact our security team privately.
Choose Send feedback in the footer, search for Send feedback with ⌘K (Ctrl K on Windows), or use the Help sidebar on a support page. The feedback window is available on the public and merchant sites after rollout.
Sign in to your Kardy account, choose Idea, Bug or Other, and describe what happened or what would help. Messages can contain up to 2,000 characters. Your account email is included so our team can follow up. Do not include passwords, access tokens, private QR codes or customer details.
Select Security to email security@kardy.com instead. Security reports cannot be submitted through the feedback form, and you do not need to sign in to see the security contact.
Wait for the delivery confirmation before closing the window. If delivery fails, your message stays in the form so you can try again. To prevent spam, allow at least 15 seconds between attempts and no more than five attempts in ten minutes across both sites.
