Save for Offline & Syncing

Save for offline downloads a world to your device so you can keep working without a connection. This page covers what gets saved, the Offline Library, and how your offline edits reach the server again.

What gets saved

Saving a world downloads the whole package:

Wiki — every page, your folder structure, and images
Maps — your world maps with their pins, regions, paths, and labels
Timeline — events, layers, and your world’s calendars
Entities & links — your cast and the relationship graph
Boards — the world’s boards (viewable offline; editing needs a connection)

You can also save an individual board — including boards that don’t belong to a world — from its Details panel on the boards page.

Your card library is separate (cards aren’t tied to a world): flip on Keep my card library offline in Settings → Offline and your cards — with their artwork and frames — stay viewable and editable on that device without a connection.

The Offline Library

Settings → Offline lists everything saved to this device: each world’s page count, size on disk, and when you saved it, plus your total storage use. From here you can:

Browse — open a saved world in the familiar hub layout
Sync now — push pending changes without waiting for a reconnect (the button shows how many edits are waiting)
Remove a world from offline storage (the trash icon)
Resolve conflicts — appears when something needs your attention (see Resolving sync conflicts)

While you’re offline

A banner appears when your connection drops — everything saved for offline stays editable underneath it. Your edits are kept on the device, in order, ready to send. New wiki pages and images you add offline work too; creating folders, maps, or boards needs a connection.

If you edit a page that wasn’t saved for offline, the edit isn’t lost: it’s kept as a local draft, and the next time you open that page you’ll be offered Restore or Discard.

Syncing back

When you reconnect, PostRoll sends your queued edits automatically and shows a summary (“3 offline changes synced”). Anything that couldn’t send yet is retried, waiting a little longer between attempts — Sync now always retries immediately. If an item you edited was also changed elsewhere, you’ll be asked to choose which version to keep — nothing is discarded until you decide.

Rarely, a change can’t be applied no matter how often it’s retried — for example if your access to that world was removed while you were offline. Those changes appear in a Needs attention list in the Offline Library, each with Retry and Discard. Either way your words are safe: a local draft copy is kept before anything is discarded.

If you were signed out in the meantime, your edits wait safely until you sign in again.

Good to know

Saved worlds follow your account — save a world on your laptop and it downloads on your phone too.
You need a connection to download a world (or board) in the first place.
Signing out removes offline data from the device; you’ll be warned first if unsynced edits would be lost.
