Privacy and local board storage
Your board, pieces and move search stay in your browser. This site does not send board inputs to a solver server, call an AI service or accept screenshot uploads.
Saved progress and sharing
The planner saves your latest board and pieces in localStorage on this device so you can return or switch languages. “Clear board” clears the saved occupied cells; it keeps your three chosen shapes. Browser site-data controls can remove all saved state.
“Copy board link” puts the board and three pieces in the link fragment after #. Anyone you share that link with can reconstruct the puzzle. The fragment is not included in normal HTTP requests. Copying requires a button press and may depend on browser clipboard permissions.
