Keylane vs ANCROM

Keylane is a privacy-first messenger for the people who matter most. Every message, voice memo, photo, file, and call is protected with end-to-end encryption — and Keylane goes further than most, using post-quantum cryptography designed to stay secure even against future quantum computers. Built for genuine one-to-one conversations. No groups, no feeds, no algorithms — just private, direct communication. WHY KEYLANE • End-to-end encrypted by default. Messages and calls are encrypted on your device and can only be read by you and the person you're talking to. Not by us, not by anyone. • Post-quantum protection. Keylane uses a quantum-resistant key exchange (ML-KEM-768) and a quantum-resistant double-ratchet protocol, giving you forward secrecy and protection against "harvest now, decrypt later" attacks. • Your keys never leave your device. Your private keys are generated on-device and encrypted at rest with a key derived from your PIN. We never receive them. • Metadata privacy. A sealed-sender design means our servers can't see who is messaging whom — only that a message needs delivering. • Unlock with Face ID or Touch ID. Convenient biometric unlock, backed by the same PIN-derived encryption — no security shortcuts. • Secure calling. Encrypted one-to-one voice and video calls, integrated with the native iOS call experience. • Rich, private media. Share photos, videos, files, and voice memos — all encrypted, with per-file quality options and in-app image annotation before you send. • No phone number required. Add a contact by scanning their QR code. No address-book upload, no discovery by phone number. • No ads. No tracking. No profiling. Keylane's business is privacy, not your data. HOW IT WORKS When you create an account, Keylane generates your cryptographic identity locally. Only your public keys are registered with the server. Everything sensitive — your profile, your private keys, your local files — is encrypted on your device. To connect with someone, you exchange an invite (for example, by scanning a QR code). From that point on, every exchange runs over a quantum-resistant double-ratchet session that provides forward secrecy: even if a key were ever compromised, past messages stay protected. DESIGNED FOR CONTROL • Block a contact and their ability to reach you is revoked immediately, at the server. • You choose who can contact you — there's no open directory. Keylane is for anyone who believes private conversations should stay private: journalists, professionals handling sensitive information, and anyone who simply prefers that their messages remain their own. Private by design. Quantum-safe by default. See https://keylane.app for more information.

ANCROM - Private Messaging ANCROM is a messenger for people who want their conversations to stay between them and the person they are talking to. No phone number, no email address, no address book upload. SECURITY BUILT ON STANDARDS End-to-end encryption with post-quantum protection Messages are encrypted on your device and can only be read by your contact. Keys are agreed using a hybrid method that combines ML-KEM-1024 and elliptic-curve cryptography (P-384), so conversations stay protected even against future quantum computers. Messages are encrypted with AES-256-GCM. A fresh key for every message Keys change with every message (forward secrecy). Even if a key were ever exposed, earlier messages stay protected, and the conversation recovers on its own. Sealed Sender Each message is encrypted as a whole before it leaves your device. Our relay servers only learn where to deliver it - not who sent it. Verified contacts Add contacts by scanning their QR code in person. Far apart? One of you creates a one-time code and reads it out, for example on a phone call; the other types it in. Both phones then show the same six-digit number - compare it before you confirm. You can also compare a safety number in the chat at any time. If a contact's security key ever changes, ANCROM warns you and pauses the conversation until you verify again. NOTHING STORED THAT ISN'T NEEDED Short-lived relay storage Our servers only pass messages on. A message is held until your contact's device confirms it, for at most 24 hours, and then deleted. Your data stays on your device Chats are stored only on your phone, in an encrypted database protected by your password. No cloud sync, no server-side history. Protected sign-up No phone number, no email address, no personal information required. Clean photos Location, camera details and other metadata are removed from images before sending. PROTECTION ON YOUR DEVICE - Screenshot protection - Auto-delete for messages - Duress PIN and panic button to wipe your data instantly - Detection of jailbroken or manipulated devices Only people you add can reach you. Messages from strangers are not shown until you add them yourself. GOOD TO KNOW Your privacy comes with responsibility: because nothing is stored in the cloud, your chats are gone if you delete the app or lose your device. There is no recovery, by design.
