Cloud Sync, Export, and Migration

Sliprail provides separate tools for keeping supported data available across devices and for taking copies elsewhere:

• Cloud Sync keeps supported settings and extension data consistent across signed-in devices
• Data export creates a selective JSON copy of cloud-backed extension data for review, backup, or migration
• Bookmark import and export uses standard HTML when you need to move bookmarks between Sliprail, browsers, or another compatible tool

These tools are not interchangeable. A cloud data export is not a full backup of a device, and Sliprail does not currently provide a general way to import that JSON file back into the app.

Cloud Sync

Cloud Sync requires a signed-in account and a plan that includes synchronization. In the desktop app, open Settings > Cloud Sync.

For a new account with no cloud settings, Sliprail may enable synchronization automatically after sign-in. When you enable or re-enable Cloud Sync and existing data is present, Sliprail asks which source should take priority:

• Use Local Data uploads this device's supported data. Conflicting cloud values are replaced
• Use Cloud Data downloads supported cloud data. Conflicting local values are replaced on this device

Data without a conflict is preserved when possible. Choose the source that contains the version you want to keep before continuing.

Choose what is synchronized

Select the settings icon beside Cloud Sync to open its controls:

• Sync extension list keeps eligible installed extensions consistent across desktop devices
• Sync theme keeps the selected theme and eligible installed themes consistent
• Per-extension sync controls supported data and settings for each eligible bundled extension
• Delete synced data removes an extension's stored cloud data after its sync switch is turned off

The current desktop panel can expose Bookmarks, Snippets, Quick Web Search, Clipboard History, and MCP. Clipboard History and MCP cloud sync are off by default. Only extensions shown in the panel support this per-extension control.

Cloud Sync covers supported settings rather than every local preference. Device-specific values such as startup behavior, administrator launch, language, HTTP proxy, local app search paths, hidden items, and the usage statistics preference remain local. Unpacked local extensions and themes are not installed on another device through Cloud Sync.

Bookmarks and Snippets also have signed-in Sliprail Web tools backed by their cloud data. Data appears there only after it has reached the cloud.

Status, storage, and deletion

The Cloud Sync control can show Syncing, Synced, or Error. Select the retry icon after an error. When the control is idle, select the sync icon to push pending local changes and then pull cloud changes.

The Cloud Sync settings panel shows current storage use and the account limit. Synced content and cloud files both count toward that usage.

Turning Cloud Sync off does not delete existing cloud data. To remove an extension's cloud data, turn off that extension's sync switch and use Delete synced data. Re-enabling global or per-extension sync asks you to choose local or cloud precedence again.

Export cloud-backed extension data

You can open the same selective export dialog from either platform:

• Desktop app: open Settings > Cloud Sync, select the settings icon, then choose Export Data
• Sliprail Web: open Settings > Data export, then choose Export data

You must be signed in. In the export dialog:

1. Select one or more available cloud data sources
2. Select Send verification code
3. Enter the six-digit code sent to the email address associated with your account
4. Select Export data and save or download the file

The code is valid for 30 minutes and can be used once. The exported filename follows sliprail-data-YYYY-MM-DD.json.

The JSON file contains one group for each selected cloud-backed extension list. Each item includes its ID, created and updated timestamps, and the fields defined by that extension. Internal sort keys are omitted.

Export boundaries

• The export reads cloud-backed extension lists. It does not include local-only records, general app settings, extension installation lists, or theme selection
• Exporting does not change or delete the cloud data
• Sliprail does not currently import this JSON format, so keep it as a point-in-time copy or use your own migration process
• The file can contain the content you selected. Store and share it according to the sensitivity of that data

If the data you need has never reached Sliprail's cloud, it will not appear in this export.

Import or export bookmarks with HTML

For a portable bookmark file that Sliprail can import again, use the desktop Bookmarks manager instead of the JSON export.

1. Run ManageBookmarks
2. Open the More menu
3. Choose Import Bookmarks or Export Bookmarks

Import can read a standard .html bookmark file. On Windows and macOS, it can also read bookmarks directly from an installed Chrome, Edge, or Firefox profile. Imported bookmarks are appended to the current collection. Existing entries are not replaced or deduplicated.

HTML export preserves bookmark and folder names, URLs, folder nesting, and an available creation or update timestamp. It does not preserve Sliprail shortcut flags, internal IDs, or separate update timestamps.

Use Cloud Sync when you want to continue using supported Sliprail data across devices. Use bookmark HTML when moving bookmarks to or from a browser or another compatible tool. See Bookmarks for the complete bookmark workflow.
