Guide updated
The game owns its saves on its own origin. This guide cannot read, restore or change cross-origin account progress; local planning tools keep separate browser data.
What to do
- Confirm save mode before closing or switching devices.
- Preserve original-site storage when diagnosing lost progress.
Numbers & conditions
Guest: memory only. Local: current browser account storage. Cloud: authenticated save plus local cache and merge. Collection union is separate from latest-save currency selection.
Common mistakes
Guest progress disappears when its game document closes. Exporting the atlas tracker does not back up the game save; do not delete the original site’s local data while finding the last good copy.
