Support and help

Need help with a video, subtitles, your account or Android TV? Contact the DualSub team.

Email support

Include your device model, app version, study and translation languages, and the steps that led to the problem. For a video issue, include its link or title and timestamp. Do not send passwords, verification codes or card details.

Videos and subtitles

Can I play any video?

DualSub works with compatible YouTube videos, local files and playback links shared by other apps. Playback, audio tracks and subtitles depend on the source. YouTube videos may restrict embedded playback. DualSub does not sell or supply third-party movies, series or streaming subscriptions.

Subtitles or translations are missing or out of sync

Check the selected subtitle and translation languages and the available tracks. Use the player's synchronization settings if timing needs adjustment. Automatic captions and machine translations can contain errors. If the issue continues, email us the video link and timestamp so we can investigate.

Android TV and Premium

What do I need on my TV?

The TV app includes a demonstration. Premium features on TV require linking it to an Android phone with an active DualSub Premium account. The exact offer and price appear in the Android app before purchase. DualSub Premium does not include subscriptions to other video services.

A local video sent from my phone will not resume on TV

The source file must still be available on the phone. Open DualSub on that phone and keep both devices connected to the same network while the TV requests the video.

I paid, but Premium is not active

Check that Google Play shows the purchase as completed, then use Restore purchases in DualSub with the same Google Play account. Do not pay again while a transaction is pending. If needed, email us your Google Play order ID and the app version. We cannot activate a purchase made through an unrelated third-party seller.

How do I manage or cancel a subscription?

Open Google Play, choose your profile, then Payments & subscriptions and Subscriptions. Review your renewal date and price there. Cancellation and refund requests are separate processes.
