Free games and verified Plus access work offline on this device. Claiming, buying or restoring requires a connection; trials still expire on their original date. Games and undo history are saved locally so you can continue when you reopen the app.
The app requires no account and has no ads, cross-app tracking, third-party analytics SDKs or developer-operated data servers.
