How do I enable the kill switch in Psiphon?

Psiphon automatically selects the best protocol for your connection. There is no manual option to change the protocol.

Yes, you can use Psiphon on multiple devices, such as Android, Windows, macOS, iOS. But, it doesn't work with linux.

Psiphon is generally free to use, but if you have a paid subscription, you can cancel it through the app store or payment provider you used.

Yes, Psiphon uses strong encryption to protect your data, but it does not have a no-logs policy. Be mindful of this when using the service.

Ensure the app is updated, check your internet connection, and try switching servers. If the issue persists, reinstall the app or contact support.
