Stegstr is open source (MIT) and came out of a 2026 contest. The only thing an invitation changes is one small tag on the profile and notes you publish through the Stegstr relay for 30 days, so the person who invited you gets credit. You can remove it any time in Settings, and it is never sent anywhere else. Privacy. How the publicity contest works.
