Restore uses the file contents only: the format and version inside the JSON, not the filename, decide compatibility.
With cloud backup on multiple devices, the last successful upload wins until a merge feature exists.
Use Backup Data in the sidebar (Operations) to save an encrypted copy locally or to the cloud, depending on backup mode.
Use Connect your cloud to pick a single provider (Google Drive or OneDrive for now). When connected, an automatic upload runs after you leave Entries or hide this tab (debounced).
Files are encrypted with your master password; the provider sees ciphertext, but anyone with full access to the cloud account could still remove files.
Very large backups may hit upload size or quota limits—if sync fails, use Backup Data (local mode) in the sidebar or keep a copy manually.
On mobile, opening the app or pulling downat the top pulls a newer cloud backup automatically (won't overwrite cloud with stale data from this device).
Restore from cloud and Restore from device both replace all local data—use them for recovery.
For the optional local MCP server (Cursor, etc.), use the same encrypted file from Backup Data and configure path + master password as described in the repo under docs/mcp.md.
