About
One box holds your whole library, with room to spare. That's the point.
Onyx seals each photo and video on your iPhone to its essence — a two-minute video that weighed 73 MB becomes a 33 KB atom. Same video, still yours. Tap it and it beams back, checked against its own seal.
Nothing moved. Nothing deleted. No account or sign-in needed. No ads. Nothing used for training.

Onyx Box keeps every photo and video you love without filling up your phone. Your storage doesn't matter anymore.
Drop one in and Onyx seals it on your iPhone and reduces it to its essence. A two-minute video weighs 73 MB; Onyx keeps it as a 33 KB atom. Same video. Still yours. Tap it and it beams back, checked against its own seal.
Do that for all of them and one phone has room for over a million photos. Stop deleting the good ones to make room for the next ones.
NOTHING MOVED. NOTHING DELETED.
Your originals stay right where they are. Onyx only reads the photos you choose, and it asks first — on Apple's own permission sheet. Want everything backed up? Turn on Onyx Subspace and your saves go home on their own. Nothing leaves your phone unless you choose it.
SIMPLE TO START. NO CATCH.
Open it, name your box, drop a photo in. That's the whole setup. Your first 50 saves are free, and they stay free.
STAMPED AS YOURS
Every photo is stamped with your Signal ID the moment it lands, and the stamp travels with it. It's yours wherever it goes, and it won't open unless it still matches its seal.
ONE BOX FOR A LIFETIME
A box is built to hold your whole library. A lifetime. Your kids' lifetimes.
MADE FOR THE WAY YOU ALREADY LIVE
Your photos and videos show up just like they always have — a grid, an album, a tap to view, a swipe to browse. Send anything through Apple's own share sheet to a friend or your socials. Bring files in from the Files app. Play your music right on your home page.
WHO IT'S FOR
Anyone who has ever seen "Storage Almost Full" and had to pick which memory to lose. Parents. Travelers. Anyone with a phone full of life.
Your memories belong to you. No one should have to choose between keeping the moment and affording the space to hold it.
