THE FILE IS LIGHT.
THE WEIGHT STAYS HOME.
Your phone keeps the atom. Home keeps the rest. Every open beams it back, checked byte for byte.
WHAT STAYS
ON YOUR PHONE.
Once a photo or video is proven safe at home, your phone lets go of the heavy copy. What stays is the atom: a tiny sealed file that knows exactly what it points to, with its origin, the day it was sealed, and its fingerprint. And its tile, so your library still looks like your library.

A real two-minute video lives at home. The phone carries only its atom.
NOTHING CHANGES
ON THE WAY BACK.
Tap it and it beams back from home. Before it plays, every byte is checked against its own seal. If a piece arrives wounded, its shield rebuilds it. If it still can't be proven, it's refused, never shown wrong.
- Sealed on iPhone
- Proven home first
- Fingerprint checked
- Shield repair
- Nothing kept twice

It travels as an ordinary file.
Share a photo or video and the person on the other end gets a normal file that opens anywhere. Onyx carries a small pad inside it, the key it uses to find the rest. Songs stay with you.
