Is Open Subtitles safe?

Clean risk

Adds downloadable or custom subtitles to HTML5 videos on streaming sites.

This extension detects the first video on a page, searches OpenSubtitles.com for matching subtitles, and displays them over the video. It also lets you drag and drop subtitle files in SRT, VTT, ASS, or SSA formats, adjust subtitle timing and appearance, view subtitle text, and jump to timestamps.

Shared hosts - 2 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Where it sends data

Destinations our analysis observed Open Subtitles contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.

  • OpenSubtitles.com

    Open Subtitles sends data to OpenSubtitles.com. No other extension we have analysed sends data here.
