Sync when you need it
Try as a guest; sign in with TutuID only when you want favorites or saves.
Isolated by design
Applets run in a restricted environment and sensitive capabilities require clear permission.
You may be wondering
Do I need to install anything?
No. Choose an app or game and it opens immediately in your browser.
Do I have to sign in?
Browsing and opening do not require sign-in. TutuID is needed only for favorites, cross-device sync, or some save features.
What data can an app access?
The detail page shows requested capabilities. Sensitive capabilities cannot be used without permission, and you can revoke access or clear data at any time.
What happens if the network or app fails?
The page keeps the latest usable public catalog and offers retry. Failed writes are never shown as successful or queued forever in the background.
