SimpleX Chat advantages:
- Privacy of your identity, profile, contacts, and metadata provided by avoiding phone numbers or any other user identifiers—protecting communication privacy from SimpleX servers and external observers alike.
- Complete protection against spam and abuse due to the absence of identifiers on the SimpleX platform; contact requires sharing a one-time invitation link or an optional temporary user address.
- Full ownership, control, and security of your data with all user data stored on client devices; messages are only temporarily held on SimpleX relay servers until received.
- A decentralized proxied peer-to-peer network enables using SimpleX Chat via personal relay servers while communicating with users on pre-configured or other SimpleX relay servers.
- Fully open-source code implementation ensuring transparency throughout the platform.
You can connect with anyone by sharing a link or scanning a QR code—eliminating the need for emails, phone numbers, or passwords during initial setup.
Your profile and contacts remain exclusively stored in the app on your device; relay servers remain devoid of this information.
All messages are end-to-end encrypted using the open-source double-ratchet protocol, delivering content through open-source SimpleX Messaging Protocol.
