Terms of Service

Last updated: July 2026

Use of Dubstack

Dubstack is a browser extension for language-learning subtitles and lookup. You are responsible for using it with services and content you are allowed to access.

Premium subscriptions

Premium adds short explanations and translation fallback. Subscriptions are billed by Stripe at the price shown during checkout. You can cancel through Stripe's customer portal.

Availability

Dubstack depends on browser APIs and subtitle data exposed by supported video sites. Netflix, YouTube, Chrome, or model providers can change their systems, so features may occasionally need updates or become temporarily unavailable.

Acceptable use

Do not abuse Premium endpoints, attempt to bypass quotas, reverse engineer server controls, or use the service for non-subtitle bulk processing.

No affiliation

Dubstack is independent and is not affiliated with Netflix, YouTube, Google, Stripe, Anthropic, or Cloudflare.
