Optional screenshot with private details removed:Find your app version in Duvrin’s About information, and your macOS and chip details under Apple menu → About This Mac. A short description of the destination, such as an external drive, is usually enough; you do not need to share your full folder path.
Keep these details private
Never send activation codes, email verification codes, browser cookies, connection tokens, authorization headers, full payment-card details, or signed and private download addresses. Check any screenshot for purchase emails, codes, and sensitive file names before attaching it.
For a download problem, an ordinary public page address is much more useful than a direct media link containing temporary access parameters. If the source is private, describe it first and support will explain what else is genuinely needed.
Missing activation email
Search the purchase inbox, Spam, and Junk for Duvrin activation code. The payment receipt is a separate message. If the code is still missing, contact us with the purchase email and order reference. You do not need to purchase again.
Refund requests
Send the purchase email, order reference, and a brief description of the request. Duvrin’s published policy provides a voluntary 14-day refund window in addition to applicable mandatory consumer rights. Acknowledging a request is not the same as issuing a refund. See the terms of use for the full policy.
Privacy and security questions
Use the same private support address and begin the subject with Privacy request or Security report. Describe the issue without sending secrets or accessing another person’s data. For a privacy request, support may need to verify that you control the relevant purchase email before acting. The privacy notice covers the full scope.
Before you write
Most reports are answered faster after a quick look at troubleshooting. If you have already tried a check there, say which one and what it showed; it is usually the fastest route to an answer. Please do not send repeated duplicate requests while waiting for a reply.
