FAQ
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 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.
