I came across [CalyxVPN](https://calyxos.org/docs/guide/apps/calyx-vpn/) while browsing through [F-droid](https://f-droid.org/en/packages/org.calyxinstitute.vpn/), 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.
