ARCA
Messages for the people who matter — delivered at the right moment. For loved ones, for your kids’ future, for your older self.
(01) Problem
We postpone the most important things we want to say. And when we do write them, they sit in a notes app nobody will ever open. A will handles property, not words.
(02) Solution
An encrypted digital vault for messages, voice, video and documents. Delivered on a date, or when you stop checking in — and only once your guardians confirm.
ARCA is a time capsule with a safety net. Write or record a message, pick a trigger — a specific date or a long absence — and name up to three guardians. Before anything is sent, they confirm your status. Content is encrypted on your device, so nobody can read it. Not even the operator.
