Saves are kept in %APPDATA%\BrokenSeal on Windows and ~/.local/share/brokenseal/ on Linux. They are left alone when you upgrade or uninstall.
.bseal.Saves are kept in the browser's own storage on your computer, about 5 MB, which is room for about 100 saves. They are not on the server, so they stay on that computer and that browser. Clearing the browser's site data deletes them.
.bseal file. Keep copies of campaigns you care about this way..bseal file, from the browser or the desktop edition.Multi-player games are kept on the server, not in your browser: see Multi-player games.
The save format is the same in both editions, so a campaign can move either way: Export it from the browser and open it in the desktop edition, or Import a desktop save into the browser.
Saves from earlier versions open in the current one; the game updates them when it next saves.
Before 0.6.0, several people could take turns at one computer (hotseat). A campaign saved like that still opens: you keep the house that was playing when it was saved, the computer leads the others, and the game tells you so. The file itself changes only when you save.
