Is this legal?
Yes! Channels is not a service provider, it utilizes your existing TV sources to provide an amazing TV watching experience.
Channels lets you cut the cord and stream live TV using existing sources available to you like an HDTV antenna. Local news, sports, award shows, and primetime television are all available for free via over-the-air broadcasts using TV towers in your area. Channels also supports cable channels, but you must have a subscription with your local cable company.
You have the rights to all of the TV that Channels is able to use.
