Data loss is rare, and we are actively working to improve system stability. In most cases, your data can be recovered. This guide covers common scenarios and recovery steps.
Even if you successfully recover your data, please report the issue through our in-app support by selecting "Report a bug" → "❗ Data loss". This helps us fix problems faster.
If these steps don't help, contact our support team—we'll respond quickly to assist you.
Before restoring a version, save the content you want to keep outside Heptabase, including important images and attachments. If devices show different content or changes have not synced, pause editing the same card across devices. Do not reinstall the app, reload data from the cloud, or overwrite data until you have preserved the content you need. If you cannot preserve it or are unsure which version to restore, contact support first. Restoring a version does not establish that a sync issue has been fixed.
Lost Card Data
Card or journal reverted to an older version
Try these steps:
Click the menu in the top-right corner of the card.
Select Version history and check for the correct version.
If you find the right version, click Restore.
If the version isn't listed, your recent edits might not have synced. Check the version history on the device where you originally made those edits.
If the card appears blank with no history:
Use the shortcut Ctrl/Cmd + O to search for your content—it might be in another card.
If these steps don't resolve your issue, please contact support.
Edits differ between synced devices
If edits made on one device do not appear on another even though both show as synced, one device may have encountered a sync issue and mistakenly reported that the data was synced.
Try this:
Check the web app: Log in to the web app to see if your data matches.
Compare across devices: If the web version matches Device B but not Device A, then Device A likely has a sync problem.
If inconsistency persists, or the web version is incorrect, please contact support with your details.
Lost Whiteboard Data
Whiteboard appears empty
If you encounter this issue, please refer to the guide: "I can enter my whiteboard, but I can't find anything!"
Whiteboard content or layout reverted
If your whiteboard content, layout, or connections reverted to an older version, try these steps:
Click the menu in the top-right corner of the whiteboard.
Select Version history and look for the correct version.
If found, click Restore.
If you can't find the correct version, please contact support, and we'll help you quickly.
