What makes LOOKLOCK different
No app is perfect and they all evolve. LOOKLOCK's core difference is twofold: it doesn't tie you to a phone number, and it doesn't force your messages (or their metadata) through a central server, because the mailbox can live on a node you run yourself. And, being an invite-only club, it isn't a mass service open to anyone.
Where we're behind (and we say it plainly)
We'd rather you hear it from us than from someone else: today Signal is cryptographically more robust. We lack ratchet-style forward secrecy (a key leak could expose history) and we don't yet have an external audit or an iOS/desktop version. On the other hand, in-app key verification (an anti-impersonation safety number) is already available, and we've published the protocol specification. None of this is hidden: we detail it, with its real status, on the security page.
About "metadata": we mean CONVERSATION metadata (who talks to whom, when). To provide the service we ALWAYS need an email address, but that email does NOT have to reveal your identity: it can be an anonymous address. So, even on the free plan, you can use LOOKLOCK hiding who you are entirely: no phone number and an identity-free email.
