About

Onyx Box changes what a file weighs. Every photo and video you drop in is reduced to its essence and sealed on your iPhone. It's kept safe at home, and your phone holds only the atom — an itty-bitty piece that barely weighs anything until you look at it. Tap it and it beams back, checked against its own seal. A two-minute video is about 73 MB. On your phone, Onyx keeps it as a 33 KB atom — about two thousand times lighter. Do that for every moment and a phone with a few gigabytes free can carry terabytes of your life. YOUR HOME PAGE My Library is your page: your picture, OWNER, and your Signal ID. Tap the QBIT strip to see your seal — the fingerprint that says it's yours. STAMPED AS YOURS Every photo is stamped as yours the moment it lands. The stamp travels with it, wherever it goes. Your Signal ID rides your Apple account, so it follows you to every phone. SEALED ON YOUR PHONE Every photo and video is sealed on your iPhone, and it will not open unless it still matches its seal. PHOTOS AND MUSIC, ONE PLACE Slide between your photos and your music. Songs play right on your home page. Albums for photos and videos, playlists for music. TRANSPORT Pick what goes out and send it through Apple's own share sheet — to a friend, or to your socials. Bring files in from the Files app. IT WORKS LIKE THE APPS YOU KNOW Your photos and videos show up just like they always have. The difference is underneath: what you keep is yours, and it doesn't fill your phone. Your memories belong to you. No one should have to choose between keeping the moment and affording the space to hold it.
