Great to hear you're having a good time with the game. Unfortunately I don't think there's an easy way to do that. You may be able to right click, inspect element and copy the save data from your browser into your local deep space mining company 2 save game folder.
In the latest version there is an export option in the pause menu when in game and an import in the options menu from the title screen. The game will be stored in your clipboard on export and read from it on import on both platforms.
