Everything you need to know about Dubmate.
Dubmate runs entirely in your browser. We don't collect your watch history, URLs, or any other browsing data — the only information we store is what's needed to manage your subscription. Full details in our Privacy Policy.
The one thing we count is how long you watch with two tabs linked. That's a single number per day — no titles, no links, no timestamps. We need it to honour our refund policy.
