Use cases

Real situations, real privacy

Most private-photo problems aren't about hackers — they're about everyday moments. Here's how Arca handles the ones people run into most.

Handing over your phone

Showing one photo shouldn't expose your whole library — or your vault.

Don't let private photos ship out with your old device.

Private photos on a device other people unlock every day.

Some photos shouldn't sync anywhere. Keep them fully local.

Download Arca and lock your first photos away in under a minute. No account, no cloud, no one but you.
