About Amethyst
Amethyst brings the best social network to your Android phone. Just insert your Nostr private key and start posting. Nostr is an open protocol that is able to create a censorship-resistant global "social" network, transferring notes and other stuff using relays. It doesn't rely on any trusted central server, hence it is resilient; it is based on cryptographic keys and signatures, so it is tamperproof; it does not rely on P2P techniques, therefore it works.
Privacy and F-Droid
F-Droid builds Amethyst from its published source code and flags anti-features such as ads, tracking or reliance on non-free services.
- Relies on a non-free network service
