Let the day unfold
Turn on Travel Mode. BlackBox keeps your route and stops as the day goes on.
BlackBox locks thoughts, memories, journals, and journeys to the time and place they happened. End-to-end encrypted. Private by default. Shared when you want.
Travel Mode traces your route. Add a voice note when a moment matters. Find both on the day they happened.
App screens with private details removed


Most of your days vanish the moment they end. BlackBox keeps them (where you were, who you were with, what it felt like) and hands the keys to no one but you.
Flip it on before you head out. BlackBox silently traces your path and splits your day into stops automatically. The longer you linger, the more it knows a place mattered. No check-ins, no taps.
Every note, voice memo, and photo snaps to the exact place it happened, dropped in automatically from its metadata. Revisit your life geospatially: a map of moments, not just destinations.
Add context in the moment or long after. Voice, text, and photos weave into threads, little time capsules you can reopen anytime.
Scroll back to any date and find it whole: the route you took, the stops you made, the words you left behind.
Share a memory, a day, or a whole journey with the people who were there. Opt in to connect. Never broadcast by default.
We cannot see your memories. No one can. That is not a promise. It is the architecture.
BlackBox is built on end-to-end encryption and biometric locks. Your memories are sealed on your device before they ever leave it, and you hold the only keys. Privacy is not a setting here. It is the foundation.
Content is encrypted on your device before it is ever uploaded, with keys only you hold. Not us, not anyone. Your memories are unreadable to the outside world.
Your BlackBox opens to your face or fingerprint alone. Even the app on your phone stays shut without you.
No ads, no profiling, no training on your life. We built BlackBox so that we could not exploit it even if we wanted to.
BlackBox is built to deepen the bonds you already have, not to perform for strangers. Every connection is chosen, every share is deliberate. It is a private world you invite people into.
Turn on Travel Mode today and start building a private, encrypted map of your life, sealed to you and shared only by your hand.
