IronCircles vs PMCT

IronCircles lets you run your own private social network. You build it, you invite the people, you set the rules, and nobody else owns it: not an advertiser, not an algorithm, not us. Inside your network, circles hold the private group chat, photos, events and lists for each group of people, from your family to your friends to a small team. Your network, your rules • Start a network for your family, your friends, a club or a team • Create circles inside it, one for each group of people • You decide who joins: invite links, admin approval and up to three membership questions • Let members vote new people in, so the group grows with everyone's say-so • Admins decide how each circle is run, and can remove anyone who should not be there • Keep your network invite-only, or let it be discovered by people looking for it No phone number, no email Signup is a username and a password. There is no phone number to give, no email address, no real name and no contact list upload. Nobody can find you by your number, because IronCircles never asks for it. Private group chat for the people who matter • Group chat and one-to-one messages, with photos, video and files • Events, lists and polls inside the same private group chat • Games to play together, with no ads between turns • Disappearing messages for anything that should not stick around Hidden chats Some conversations should not be one tap away on an unlocked phone. Hide a chat behind its own lock and it disappears from your list until you unlock it. Hidden chats stay invisible to anyone who picks up your phone, and they are encrypted like everything else. Share photos privately • Share photos and video with your family without posting them to a public feed • Keep a private photo album inside each circle, seen only by its members • Photo vaults lock a private photo album behind its own key, invisible on an unlocked phone An encrypted messenger with post-quantum encryption Every message, photo, video and file is end-to-end encrypted on your device before it is sent. IronCircles uses post-quantum encryption: ML-KEM-1024 key exchange (the NIST standard, formerly CRYSTALS-Kyber) in a double ratchet, and XChaCha20-Poly1305 for each message. Attackers can record encrypted traffic today and try to decrypt it once quantum computers are good enough; post-quantum encryption is built to close that gap now. • End-to-end encrypted group chat and direct messages • Post-quantum encryption with forward secrecy • Two-factor authentication with any authenticator app Made for family Give your family a network of its own: the group chat, the shared photo album, the calendar and the grocery list in one private place. Children can share with the family without public profiles, followers or strangers, and nobody needs a phone number or an email to join. No ads IronCircles has no ads and no advertising business. Your network is not a product we sell to anyone: your messages and photos are not used to target you, and nothing in your private photo album is training data. Why people choose IronCircles • Your own private social network, run by you • A private group chat with no phone number required • An encrypted messenger with post-quantum encryption • Hidden chats and photo vaults for what stays private on your phone • A place to share photos privately with family and friends • No ads, no public feed, no strangers Start your network, invite your family, and keep your private group chat, your photos and your plans in one encrypted place that answers to you.
