Where Are Save Files Stored? Backup & Cloud Sync Guide

Knowing where SiNiSistar 2 stores its save data matters when you install the R18 patch, try mods, or move to a new PC. On Steam, first open your library, right-click SiNiSistar 2, and use Manage > Browse local files to open the installation folder. Check it for a 'save' or similarly named folder. If it is not there, the save data is in your user profile's local app-data directory instead: press Win+R, type %APPDATA% and %LOCALAPPDATA%, and look for the developer or game name. On macOS, check ~/Library/Application Support. To back up, copy the entire save folder somewhere safe before patching or modding, and restore it the same way after a reinstall. Always use the 'Return to Menu' option before closing the game so the save icon disappears - quitting mid-write is the most common cause of save corruption.
