FAQ

Masterboard stores all game data in a local SQLite database. No data is sent to any server.

PlatformLocation
Windows%APPDATA%\Masterboard\
macOS~/Library/Application Support/Masterboard/
Linux~/.config/Masterboard/

The database file is masterboard.db in that folder.

All your games, repertoires, and training history live in a single SQLite database (masterboard.db) in the data folder above. To back up everything, copy that file to a cloud drive, external disk, or other safe location while the app is closed. Restore by copying it back.

To share or archive a single repertoire or an opponent report, use the PGN export actions in the Openings side-nav and on the Reports page.

Yes. Go to Settings → Engine Configuration, click + Add local engine…, and select your Stockfish binary. Any UCI-compatible engine works. See Engine Setup for details.

ChessBase can export to PGN: File → Export → PGN. Import the resulting file with Masterboard’s PGN import. All variations and annotations are preserved.

Can I open a .pgn file by double-clicking it?

Section titled “Can I open a .pgn file by double-clicking it?”

Yes. Masterboard registers as a handler for .pgn files on Windows, macOS, and Linux, so double-clicking a PGN file (or choosing Open with → Masterboard) opens it in the app. You can also import PGN files from inside the app — see Importing Games.

Only when you explicitly trigger a chess.com or Lichess game import. Masterboard does not send telemetry, crash reports, or any other data online.

The current version is free. A Pro tier with additional features (cloud sync, team features) is planned but not yet available.

The engine panel shows nothing — what’s wrong?

Section titled “The engine panel shows nothing — what’s wrong?”

Masterboard looks for a Stockfish binary in two places at startup:

  1. An engines/ folder in the same directory as the Masterboard binary.
  2. Your system PATH.

If neither is found, the engine panel stays blank. Fix:

  • On Windows: place stockfish.exe in an engines/ folder next to Masterboard.exe.
  • On macOS/Linux: install Stockfish system-wide (brew install stockfish, apt install stockfish) or add it with + Add local engine… in Settings → Engine Configuration.

See Engine Setup for more detail.

Analysis is very slow — how do I speed it up?

Section titled “Analysis is very slow — how do I speed it up?”

Increase the thread count in Settings → Engine Configuration to use more CPU cores. A good setting is (number of logical CPU cores − 1).

Also check that no other CPU-intensive applications are running while analysis is in progress. Batch analysis of many games is best run in the background while you step away.

Not currently. Masterboard is local-first. Cloud sync is planned for a future Pro tier.

Why does the app show a security warning on first launch?

Section titled “Why does the app show a security warning on first launch?”

Masterboard is not yet code-signed with a commercial certificate. Windows and macOS may flag the app as from an “unidentified developer.” See Installation for instructions on bypassing the warning safely.
