Every feature in Phantom Chat was engineered with a single question: what would a privacy absolutist demand?
Among the few messengers that combine the Signal Protocol with NIST's post-quantum algorithm (ML-KEM-768, the FIPS 203 standard). Every conversation is encrypted with both classical and post-quantum keys at once — if either holds in 20 years, your messages stay safe. WhatsApp doesn't have post-quantum encryption; Signal added it in 2024 and Apple added PQ3 to iMessage the same year.
Every message is encrypted on your device before transmission using the Signal Protocol's Double Ratchet — the same forward-secrecy standard used by Signal, WhatsApp, and Google Messages. Only the recipient's device holds the keys to decrypt. We can't see your messages. Our servers can't see your messages. No one in transit can see your messages.
Your long-term identity key is generated inside the iPhone's Secure Enclave — a tamper-resistant chip isolated from iOS itself. The private key cannot be extracted, even by malware or jailbreaks.
If you still have your phone and it's at risk of being seized or compromised, you can instantly delete your account and all data. The Lock Screen widget trigger is free for everyone; two more triggers — a shake gesture and a separate reset PIN — are part of the Personal plan. All resets use a secure multi-pass overwrite so deleted data cannot be recovered. Note: these triggers require physical access to your device — there is no remote wipe from a different phone, by design.
No phone number, no email, no real name. Sign up with just a username (plus acceptance of the Terms and Privacy Policy). There's no public directory and no username search — the only way to connect is an invite code or QR. The account isn't tied to your SIM, your carrier, or any leaked identity database.
Choose from 76+ custom app icons, set themes, and make Phantom Chat feel like yours. Contacts are added through expiring invitation codes (single-use up to 500 joins; duration from 1 day to never — your choice).
