What EmuSync is

EmuSync is a free app that syncs game save files between devices by linking save locations to shared storage. It is aimed at people playing emulator or non-Steam games on multiple devices, as well as anyone wanting an additional save backup. Storage can be provided by Google Drive, Dropbox, OneDrive, or a local or shared folder. Users can set save locations, have the app detect saves, and choose automatic or manual syncing. A local backup and restore feature is included. Steam Deck users can check sync status through a Decky plugin without switching to desktop mode. Advanced users, scripts, and third-party automation tools can use its local HTTP API; the API requires no authentication and is documented as device-only, not network-accessible. The privacy policy says personal information is not collected, stored, or transmitted, and app data stays locally or in the selected cloud provider. Windows 10 and 11 x64 are confirmed working; Linux instructions cover Steam Deck, and modern Linux devices are expected to work. There are no planned Android or iOS versions. The Windows installer is unsigned and may trigger SmartScreen warnings.
