Haven

Haven is a private and censorship-resistant location sharing app for Android and iOS, running on Nostr using the Marmot protocol.

Private and censorship-resistant location sharing.

Haven is an end-to-end encrypted location sharing app that requires no personal information at sign-up and uses no central server. Your location is encrypted on your device before it is sent to decentralized Nostr relays. It can only be decrypted by members of your location sharing circle after they fetch your latest location information from the relays. You can select the relays you want to send location updates through, and/or run and use your own relays. Haven requires no phone numbers, emails, or any personally identifiable information before you can start using it. It is open-source, so all of its privacy guarantees are verifiable.
