PRIVACY & SECURITY
Your screen is yours alone.
Castla was built knowing it carries something as personal as your phone screen. The picture takes the shortest path, encrypted, and never stops anywhere along the way.
Direct connectionWhenever possible, the picture flows straight between phone and car, never touching a server.
Encrypted transferIf a direct path can’t be made, the stream is relayed encrypted. The server can’t see it.
No recordingPicture and audio are never recorded or stored.
