Coffer

Coffer とは？

Coffer is a private space for families to share photos and memories — with no accounts for recipients, and no access for anyone else. Not even Coffer. Every photo is encrypted on your device before it leaves. The server stores only ciphertext. No algorithm, no feed, no engagement loop. To share: send a link and a 6-digit code. They open it, enter the code, and see your photos. No sign-up. No app to install.
