If you're asking about nostr:nprofile1qqsdhc93hklp988r3km4844fjln298nf8t7s92sar7dsqha88ph9cfspz4mhxue69uhhyetvv9ujuerpd46hxtnfduhsz8thwden5te0dehhxarj9e3xjarrda5kuetj9eek7cmfv9kz7qg4waehxw309aex2mrp0yhxummnw3ezucn89uv7r8lk, it's very private and secure. Besides the blog nostr:nprofile1qqsqqqqqqqr99ezjae52qyv8lvyv3x2fdj6xedgar2sgq0gx8t8dhfcpyfmhxw309ahx7um5wf4xztttv9exjttgw368qtngv4nh2un09e3k7mf0qy88wumn8ghj7mn0wvhxcmmv9uq3gamnwvaz7tmwdaehgu3wxymrvvfwd9hj7jegwrl shared with you, you can also read this explanation:
