History and recovery

Choose the right recovery tool

Situation	Start with
You just made an unwanted edit	Edit → Undo
You need an earlier checkpoint	The History panel, when available
You deleted a project in account mode	Trash on the dashboard
Browser-local data was removed	An exported backup

Use history checkpoints

In a server-backed project, open the History panel to create and inspect checkpoints. Give a checkpoint a useful description before a substantial rewrite, import, or other major change.

Open a history entry to compare changes. Restoring an entry records a new history event rather than erasing the later timeline. You still need permission to modify the project.

Checkpoint history is not a record of every keystroke. Use it deliberately at milestones, and use Undo for immediate editing mistakes.

Use a submission snapshot when you need the exact PDF and source sent to reviewers. A checkpoint is useful for editing history; a frozen snapshot identifies an external handoff.

Recover a deleted project

In account mode, inspect Trash and restore the item if it is still available. Permanent deletion removes that recovery path. Do not treat local-mode deletion as recoverable through the server’s Trash.

Preserve a separate backup

Download the editable project ZIP as well as important PDFs. Keep required packages and fonts with your backup plan. For larger server-backed captures, inspect the submission snapshot and folder backup options.

If a sync failure is involved, preserve the current device’s work before clearing data or re-importing. See saving and offline use.
