On your Mac, not their servers. Connect an account once — Cold Storage keeps an encrypted, searchable copy on a schedule. Forever.
Everything happens on your Mac, from your own session. Nothing is ever uploaded.
Media is encrypted at rest with AES-256, under a key wrapped by your passphrase — never the passphrase itself.
Every download is queued to disk before the backup starts, so a crash or power cut just finishes on the next launch.
Starts at login, and schedules are wall-clock based — a laptop asleep for a week is due the moment it wakes.
Seven run completely hands-off. The rest you drop in yourself — anything matching an export that lands in your Downloads is picked up automatically.
Free and open source. Open the DMG, drag to Applications, done.
