Maybe it's naïve. But I don't think it's really aimed at people who have already declined to participate in social media on privacy grounds. Rather, I suspect the idea is to provide an easier way of managing available controls for people who don't want to give up social media but who are somewhat concerned to reduce their privacy exposure to the world. That has to be a good thing - assuming it works and they're not doing anything nefarious in the background.

All that said, since the app is free and since they claim they're not slurping personal data, I do wonder how they plan to monetise this.

Managing social media permissions is the point of the app.

Is there any benefits of auto insurance for people that don't have cars?

Being dubbed a "Privacy Assistant", it could be construed as having implications beyond just social media.

Jumbo helps in deleting old Google Search, and Alexa voice recordings. So it's beyond social media in that sense. Tomorrow we will support Tinder, and more.
