Support.

Contact support

Write to dinhquangvinh92@gmail.com. Support is available in English and Vietnamese. We aim to reply to Member support requests within three business days. Urgent policy requests from Chrome Web Store or a payment provider are handled sooner.

What to include

• The YTDub extension version, your Chrome version, and your operating system.
• What you expected, what happened, and the steps that reproduce the issue.
• Your selected language and whether the issue affects captions, translation, speech, synchronization, login, or Member status.
• For a public video issue, the public YouTube URL only if you are comfortable sharing it.
• For billing, the receipt or invoice reference and the email used at checkout.

What not to send

Do not send passwords, access or refresh tokens, cookies, card numbers, bank login details, full subtitle text, or links to private videos. A support report is for diagnosis, not for uploading private content.

Before you write

Confirm that the extension is enabled for YouTube, refresh the video once, and check whether the video has captions. If the problem is your account or expiry date, open Account on this website and sign in with the same Google account used for YTDub.

Billing and refund requests

We investigate errors, duplicate charges, and missing Member access. Review the Refund Policy before requesting a refund. Reporting a technical issue does not itself change the refund policy or extend a prepaid package.
