Your games stay with you.

Game files and saves
Imported ROMs, game titles, local play history, screenshots and save states are stored in your browser. They are not uploaded to our server. Save backup imports are processed locally; exports are downloaded to your device. We do not provide account registration, cloud saves or a cloud game library in this version.
Ordinary web requests
Your browser downloads the app, fonts and emulator files from this site, hosted by Cloudflare. These requests expose ordinary connection information such as an IP address to the hosting service. This version includes no advertising, analytics scripts or third-party cover lookups. It does not send imported game filenames or ROM contents in those requests.
Browser storage
IndexedDB holds your local games and saves. A service worker may cache the app and engine for offline use. Storage is limited by your browser and may be removed. You can remove individual games, clear site data, or export save backups. Persistent-storage permission helps against automatic eviction but does not prevent deliberate clearing.
Read Cloudflare’s privacy policy for its handling of hosting traffic.
