Nostr Vault

about

description

Nostr Vault is a self-custodial Android Nostr client with your own relay and media server running directly on your device. Most Nostr clients are a window onto someone else's relay. Nostr Vault is the relay. A full Haven relay runs on your phone, so every note you write and every note you receive is written to storage you own before it goes anywhere else. If every relay you use disappeared tomorrow, your copy would still be on your device. HOW IT WORKS The app runs a personal relay on-device with five separate stores: an inbox for what people send you, an outbox for what you publish, a chat relay for private messages, a private relay only you can read, and a local feed cache. Your posts are written locally first, then broadcast outward to public relays on your terms. Incoming events are pulled in and kept. Because the relay is yours, notifications are generated entirely on-device from your own event stream. There is no push server — not Google's, not ours. Nothing about who contacts you, or when, is visible to a third party. A Blossom media server runs alongside it, so images and video you post are hosted from your own device and mirrored to external Blossom servers you choose, instead of being uploaded to someone else's host by default. A Web of Trust filter, built from your follow graph, decides what the relay accepts, which keeps spam out of your own storage rather than filtering it after the fact.
