What is Cloud Sync?

Cloud Sync keeps your records the same on all your devices, including between an iPhone and an Android phone. Each device that uses it keeps an end-to-end encrypted copy of its data on WitnessWork's server, and your other devices on Cloud Sync combine those copies, usually within seconds while the app is open. It's the default for devices that haven't chosen a sync option. Open Settings → Device Sync to see which option this device uses, turn sync off, or switch to iCloud (Google Drive on Android). A device syncs one way at a time, and only with your devices that use the same option. Photos don't sync with Cloud Sync yet; they stay on the device that added them. When Cloud Sync needs Supporter access, or WitnessWork has paused it for a while, Settings → Device Sync says so; your changes stay on this device and sync once it's back, and Sync now checks again. A new phone you set up from your account's QR code or recovery key gets your records through Cloud Sync without a restore step. If your newest backup is newer than every Cloud Sync copy, for example from a phone that stayed on iCloud, the new phone offers to restore it too.
