FAQ
How many devices can one account use?
One account signs in on multiple devices with settings synced. Hit the limit? Sign an old device out right from the client.
Will overseas video buffer?
Smart traffic shaping puts audio/video on the lowest-latency route and switches paths automatically at peak times — HD playback rarely buffers.
Do you log my browsing?
No. We don’t record browsing activity; authentication is per-device, and you can revoke any session from any signed-in device.

From the network layer to the client experience, every choice is grounded in real day-to-day use.
