Cloud Saves
Sync player progress across every device so players never lose their game
Flexible Data Format
Save data is a plain string, so you can serialize any structure — JSON, MessagePack, or custom format — without schema constraints.
Instant Cross-Device Sync
The latest save is always available from any device as soon as the player authenticates with their horizOn account.
Player Retention
Players who know their progress is safe are far more likely to return after switching devices or reinstalling.
