If you want to improve your privacy, consider utilizing a service that masks your IP address (e.g. a VPN or Tor) from trackers online. The relay also learns which public keys you are requesting, meaning your public key will be tied to your IP address. Information shared on Nostr can be re-broadcasted to other servers and should be assumed permanent for privacy purposes. There is no way to guarantee the deletion of any content once posted. Development Overview This repository is split between Amethyst, Quartz, Commons, and DesktopApp: • **Amethyst** - Native Android app with Kotlin and Jetpack Compose • **Quartz** - Nostr-commons KMP library for protocol classes shared across platforms • **Commons** - Kotlin Multiplatform module with shared UI components (icons, robohash, blurhash, composables) • **DesktopApp** - Compose Multiplatform Desktop application reusing commons and quartz The app architecture consists of the UI, which uses the usual State/ViewModel/Composition, the service layer that connects with Nostr relays, and the model/repository layer, which keeps all Nostr objects in memory, in a full OO graph. The repository layer stores Nostr Events as Notes and Users separately. Those classes use LiveData and Flow objects to allow the UI and other parts of the app to subscribe to each Note/User and receive updates when they happen. They are also responsible for updating viewModels when needed. As the…
