SimpleX Chat Advantages

• Privacy of your identity, profile, contacts, and metadata: SimpleX Chat stands out by not utilizing any phone numbers or identifiers commonly used by other messaging platforms. This ensures that your communication remains confidential, hidden from both SimpleX platform servers and potential eavesdroppers.
• Complete protection against spam and abuse: As SimpleX does not employ any identifiers, you can only be contacted if you voluntarily share a one-time invitation link or a temporary user address, effectively shielding you from unwanted contact.
• Full ownership, control, and security of your data: SimpleX exclusively stores user data on client devices, with messages only temporarily held on SimpleX relay servers until they are received. This guarantees that your data remains secure and under your control at all times.
• Decentralized proxied peer-to-peer network: SimpleX Chat provides the unique advantage of allowing users to communicate via their own relay servers or pre-configured SimpleX relay servers. This decentralized approach offers flexibility while maintaining the highest level of security.
• Fully open-source code: SimpleX Chat is developed using open-source technology, reinforcing its commitment to transparency and enabling users to verify its security implementation.

Start using SimpleX by connecting with others through quick and convenient methods such as sharing a link or scanning a QR code. No emails, phone numbers, or passwords are required, simplifying the onboarding process.

All profile and contact information is securely stored within the SimpleX app on your device, ensuring that relay servers have no access to this sensitive data.

SimpleX Chat guarantees end-to-end encryption through its usage of the open-source double-ratchet protocol. Additionally, messages are delivered via open-source SimpleX Messaging Protocol utilizing relay servers.
