The data saved on this web service is volatile. This means that the data is not persisted on the server-side (e.g., a database server across the network); rather, the actual data resides in the browser of your smartphone or computer. Consequently, there is no functionality to synchronize data between devices.
Data such as games and settings will not disappear when you close your browser. However, it may be lost due to the following events:
- Deleting browser history or site data through user action.
- Deleting or reinstalling your browser.
- Exceeding storage limits.
- Browser updates or malfunctions.
- Changes in data storage methods by the service provider.
When using this website, please keep the above in mind and use it as an impromptu practice environment for blindfold chess.
