A small icon appears when you're watching a video that has been verified on CaptainFact.io. It tells you, based on votes, if the statement you're hearing (or what is shown) is believed to be true or false.
When clicked, the CaptainFact icon displays facts and comments about current statement and their respective scores.

- Why do you need storage permissions?
We store a local cache of videos IDs that exist on CaptainFact. This cache gets updated when you visit YouTube if it's older than 15 minutes. This is a privacy improvement that guarantees we don't track the videos you're watching and don't send unnecessary requests.
- Why do you need tab permissions?
Because the script is injected programmatically in the background (only if video is known from cache) and to be able to turn off CaptainFact on all tabs when you unselect it from the extension popup.
You can check by yourself in chrome/extension/background.js (look for chrome.tabs.)
- Why do you need Youtube permissions?
To be able to inject the facts overlay on YouTube videos.
- Why do you only inject on youtube.com and not in embedded players everywhere else?
We may want to implement this in a separate release in the future. We don't want to implement this feature in main extension cause it means asking for permissions to access all your sites.
- Can I add sources on videos directly from the extension?
Not at the moment.
