I came across CalyxVPN while browsing through F-droid, it seems to be offered by the same people who make CalyxOS. I couldn’t find much discourse about it online, is it reputable enough to use?

My use case would be to hide whatever I do online from my ISP (I’m not torrenting, just browsing).

And yes, I know free VPNs are untrustworthy in most cases but this seems to come from a somewhat privacy respecting background so I was curious.
