SimpleX Chat

SimpleX·SimpleX.SimpleX-Chat

SimpleX - the first messaging network operating without user identifiers of any kind - 100% private by design! iOS, Android and desktop apps 📱!

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.
