UVE detects compatible video and audio elements on the current page and applies your selected playback settings directly in the browser.

Core playback controls and preferences are handled locally. Your saved settings remain in the extension storage on your device.

Some websites use custom players, embedded frames, DRM, or other restrictions. Because of this, individual features may not work on every website or video player.

UVE is free to install and use within the Free plan limits.

UVE Pro is an optional paid upgrade that unlocks higher limits and additional features. Payments are securely processed through Stripe on the official UVE website.

An account is not required for the core Free features. License activation is only required when using UVE Pro.


We do not sell user data or browsing history.

Optional features may send limited network requests for:

• UVE Pro license validation
• OpenSubtitles search
• YouTube dislike counts
