H33 Custody › Communication Custody › Secure Messaging
Communication Custody · Solution
Messaging today is either private or preserved. Not both.
Signal protects privacy and leaves no preservable record. Email preserves the record and reads like a postcard. H33 Secure Messaging lets you have both — private while conversations are live, verifiable when they need to be preserved.
Why the privacy/preservation tradeoff is artificial
Most messaging products assume you want one or the other. End-to-end encryption with no provider key access — and no preservation. Or full-text indexable archives — and an obvious target for subpoena, breach, or insider abuse. But for the conversations that actually matter — legal communications, executive decisions, family medical discussions, evidentiary records — you want both privacy while live and verifiable preservation when the time comes.
End-to-end encrypted by default
Conversations stay end-to-end encrypted while they're happening. Only the participants can read them. The platform never holds the keys. Standard secure-messaging guarantees, post-quantum where it matters.
Verifiable preservation on participant consent
When a conversation needs to be preserved — legal hold, evidentiary need, inheritance event — participants can release a verifiable record without exposing the keys that secured the conversation in the first place. The preservation is opt-in, participant-controlled, and verifiable to outside parties.
Designed for the conversations that matter
