How sync and backup work

With Dion Pro, your devices share one encrypted backup: start a movie on your iPhone and resume it on your Apple TV, with your favorites, sources, and player settings following along.

What syncs

• Watch progress for movies and episodes, and where you left off.
• Bookmarks — saved movies, shows, and favorite channels — and your recently watched channels.
• Audio and subtitle preferences, both your global defaults and the per-title choices the player remembers.
• Player settings — skip intervals, subtitle appearance, and similar preferences.
• Your sources — supported sources you've added reappear on new devices. With Sync Layout on, your Home, Navigation, and Library organization stays the same across devices too.
• Guide and Live TV configuration — EPG sources, category order, custom categories, hidden channels, and channel customizations.

Sign-ins and source restoration

Configurations for supported sources can be restored from the encrypted backup. Some services may still ask you to sign in again. Plex sources are not included in backup, so sign in to Plex on each device.

How it's protected

Backup data is end-to-end encrypted: your devices encrypt every record before upload, and the encryption key is shared only between your devices — via your iCloud Keychain, or directly when you link a device with a QR code or PIN. Dion's servers store only encrypted data and cannot read its contents.

Status and manual sync

Settings → Backup shows whether backup is active, when the last backup ran, which sources are included, and every connected device. Sync Now forces an immediate sync; otherwise changes sync automatically in the background.
