About SimpleX Chat

Unlike any other existing messaging platform, SimpleX has no identifiers assigned to the users - it does not use phone
numbers (like Signal or WhatsApp), domain-based addresses (like email, XMPP or Matrix), usernames (like Telegram),
public keys or even random numbers (like all other messengers) to identify its users - we do not even know how many
people use SimpleX.
