Where Are Keeper Save Files Located?
Keeper stores Microsoft Store saves in its Xbox package folder and config under AppData Local Keeper. The Steam local path is undocumented.

Keeper is an Unreal Engine 5 game, but only the Microsoft Store layout is documented well enough to quote. Config goes to %LOCALAPPDATA%\Keeper\Saved\Config\WinGDK and Xbox saves go to the package wgs folder. Both paths below are verified for that build.
The Steam and GOG local save folders have no reliable public documentation, so this post does not invent one. Steam Cloud is enabled for App ID 3043580, which covers most Steam players. If you run the Steam build, let Cloud do the work and use the Proton prefix path on Linux to reach the same tree.
Where Keeper stores this, by platform
%LOCALAPPDATA%\Keeper\Saved\Config\WinGDK
Verified config root for the Microsoft Store build. WinGDK is correct here, while Steam would use a Windows folder instead. The local Steam equivalent is not publicly documented, so it is left out rather than guessed.
%LOCALAPPDATA%\Packages\Microsoft.PaganIdol_8wekyb3d8bbwe\SystemAppData\wgs
Verified Xbox save container for the Store build. Files inside wgs have opaque names, so back up the whole folder with the game closed. Do not mix these with Steam .sav files.
<SteamLibrary>/steamapps/compatdata/3043580/pfx/
Steam Play prefix for App ID 3043580. The Windows save tree is mirrored inside the prefix drive, and Cloud data also appears under ~/.steam/steam/userdata/<steamid>/3043580/. The native Steam Windows folder name itself is undocumented.
Frequently asked questions
Where is the Keeper save for the Xbox app on PC?
Look under %LOCALAPPDATA%\Packages\Microsoft.PaganIdol_8wekyb3d8bbwe\SystemAppData\wgs. The files there are opaque Xbox containers without readable names, so copy the whole wgs folder with the game closed instead of picking single files.
Can I copy a Keeper save from Game Pass to Steam?
They are not interchangeable by hand. Steam uses plain .sav files while the Xbox container format is different, and the profile files conflict. Stick to cloud sync per store rather than converting folders between them.
Does Keeper support cloud saves?
Yes for the store you bought it on. Steam Cloud, Xbox Cloud and GOG Galaxy each cover their own build. Cross-save between Steam and Xbox is not supported, so each store keeps its own progress.
