Hola is free for private (non-commercial) use on PCs and Macs, and requires a subscription on i OS and Android.
Commercial use of Hola for business class VPN is available through our Luminati service.
When your device is not in use, other packets of information from other people may be routed through your device.
Hola does this securely, not allowing any access to any of your information. As with any new technology, in addition to the benefits it brings there can be workarounds (such as in Wi Fi where malicious people can try to hijack your Wi Fi hotspot).
Yes, consumers can pay a fee to only use the Hola VPN, but not contribute their unused resources to the network.
