# How does syncing work across my devices?

You add each device once, and from then on a single block locks all of them at the same time. Start protection on one device and your distractions go quiet everywhere you have synced. There is no need to set it up separately on each, and no way to escape by switching devices.

## Specifics

- Syncing is what makes a hard lock meaningful: an unsynced device is an unlocked device.
- Add every device you own before your first Nuclear session.
