Local-first
Privacy
Game and BIOS files selected in the file picker are passed directly to the emulator in your browser. This application has no upload endpoint and does not send their contents to our server.
Browser storage
Emulator settings, save files, and save states may be stored in local browser storage or IndexedDB on your device. They remain available to other people using the same browser profile. Clear this site's storage in your browser to remove them.
Emulator runtime
EmulatorJS code and emulator cores are loaded from the official cdn.emulatorjs.org content-delivery network. That provider receives normal request information such as your IP address, browser user agent, time, and requested files. Your selected game and BIOS file contents are not sent to that CDN by this interface.
Server logs
Like most websites, the web server may retain short-term security and operational logs containing IP address, time, requested path, response status, referrer, and browser user agent. These logs are used to diagnose faults and prevent abuse.
Accounts, analytics and advertising
This version has no accounts, analytics tracker, advertising SDK, public upload, or payment system. If those features are added later, this notice will be updated before they are enabled.
