Can I close the tab or stop a sync halfway?

Step by step

1. Start a sync on the Sync page and leave that tab open while it runs; the extension reads Steam, and the tab saves the events to your account in batches.
2. If you must stop, click “Stop & save” under the counter; the events pulled so far are kept.
3. The result screen reads “Stopped early” above the count of saved events; click “Back to sync options” to return.
4. A full sync reads from today backwards, so the newest events are saved and the oldest are the part that is missing.
5. Open the Coverage block on the Sync page, which shows the stretch that has not been checked, and click “Fill first gap” to fetch it.

Good to know

• The extension only reads Steam; the open Sync tab is what receives the events and saves them to your account.
• “Stop & save” is offered only while events are being pulled from Steam. Once the page is writing the last batch, it has nothing left to stop.
• “Catch up now” and “Check for new events” read only from today back to your latest saved event, so they do not fetch an older missing part.
• “Rebuild everything instead” reads the whole history again; events you already have are skipped, not added twice.
• A stopped sync appears in “Recent syncs” with the status text “saved · stopped early”.
• A counter that stands still is a different case, covered in the answer on slow syncs, and so is an error screen, covered in the answer on failed syncs.
