got some time to fix the private backup feature on Flycat.
even if you don't have a umbrel device, you can still back up your own nostr data by running your own relay on your Macbook and adding ws://localhost:8080 to your relay on flycat website, It just works. Full tutorial in the link, hope you like it~ https://flycat-web.vercel.app/article/45c41f21e1cf715fa6d9ca20b8e002a574db7bb49e96ee89834c66dac5446b7a/47858
