It's one of the VPN products I saw on fdroid, but I couldn't find payment info and it says it's experimental. Has anyone tried it and have a baseline on how it is compared to other VPNs? Also do they have payment methods? I couldn't find them last time I looked and I'm worried it's a free VPN

I'm working on an old tablet and couldn't figure out how to switch to dns over https, so I got an app that assisted. I found one that only had 1000 downloads, no reviews, and just someone's name as the creator so I thought it was safe, but it's asking for my location to scan wifi signals. Is that phishy or standard issue?
