no? I am using it on Jio Fiber and Jio Mobile data, works fine either ways but its not suited for you if you are constrained to mobile data
basically, its an aggregator, bypasses all paywalls from filehosters like Mega, torrents etc, and then just serves it to you from their servers, then you can just use something like Stremio and have a bunch of add-ons from real debrid to scrape content and play them at will.
