Zas moves things — files, photos, text — between your devices and the people you choose, then gets out of the way.
Send something from one device, use it on another, done. No cables, no emailing yourself, no chat with yourself growing forever. Whatever you don't pin leaves on its own, so there is nothing to tidy up later.
Messengers are built for conversations: what you send yourself piles up in an endless chat, photos get compressed, and your files live on their servers. Zas sends the original — any size, uncompressed — encrypted so only your devices can open it, and it disappears when its time runs out.
Those are warehouses: you store, sort folders, manage quotas and pay to keep everything forever. Zas is a corridor: things pass through, get used, and leave. Nothing to organize, nothing piling up — and the server never sees what is inside, because everything is sealed on your device before it travels.
Everything is encrypted on your device before it leaves. The server stores sealed boxes it cannot open: no filenames, no content, no previews. Even public share links carry the key in the link itself — it never reaches the server.
Yes. Share one item with a public link that dies when the item does, or share a whole channel with someone — everything in it stays end-to-end encrypted.
