FAQ
What does YumSub do?
It shows two or three subtitle lines at once on Netflix, Disney+ and YouTube — the language you are learning and one you know — and turns every word of the learning line into a dictionary lookup: meaning, part of speech, gender, plural and verb forms, with one click to save it.
What do I get with a subscription?
Context-aware translation of whole subtitle lines by a large language model, instead of the free machine-translation path. Translations are cached and shared, so popular shows load instantly.
Does it work without paying?
Yes. Dual subtitles, the dictionary and saved words are free. Without a licence the second line uses the free translation path.
How many devices?
One licence is for one Chrome profile at a time. You can move it to a new computer yourself from your account page, once a week.
How does the trial work?
Create an account and confirm your email: you get 7 days of the full version, no payment needed. Afterwards you can buy a month or a year, or keep using the free version.
How do I pay?
bKash, Nagad, Rocket, Visa, Mastercard, Amex or internet banking, through SSLCommerz. Nothing renews automatically — you buy a month or a year, and we email you before it runs out.
Can I cancel?
There is nothing to cancel: a licence simply runs until its end date unless you buy more time. See the refund policy for refunds.
What data do you collect?
Subtitle lines are sent to our server to be translated, and nothing else from the page. No browsing history, no tracking. See the privacy policy.
