ZeroSynq

ZeroSynq is a private messenger for people who want their conversations to stay theirs. Everything you send is end-to-end encrypted on your phone before it leaves. Your private keys are created on your iPhone and never leave it. Our servers only pass along locked messages they cannot open. MESSAGES THAT DISAPPEAR Every message has a timer and is deleted automatically, from 5 minutes by default. Nothing piles up on a server. PROTECTED AGAINST TOMORROW'S COMPUTERS ZeroSynq combines classic encryption with post-quantum encryption (ML-KEM), so messages recorded today stay locked in the future too. NEW KEYS EVERY DAY Your chat keys change daily. Even if a key were ever stolen, it would only open a small piece of the past. HIDDEN SENDER Text messages between ZeroSynq apps are delivered without saying who sent them. Only the person you write to can see it is you. SAFETY NUMBER Compare a number with your contact to be sure nobody is in the middle. ZeroSynq warns you if it ever changes. ENCRYPTED CALLS Voice and video calls with end-to-end encryption. EXTRA PROTECTION, YOUR CHOICE App lock with PIN or Face ID, a second "duress" PIN, a panic button that wipes your messages in one tap, screen hiding while recording, a private keyboard, and more. GROUPS, PHOTOS, VIDEOS AND FILES All encrypted the same way. No ads. No tracking. No selling of data. ZeroSynq is invite-only at the moment. To request access, email [email protected].
