How can I bypass Deco?

So basically my mum and dad have this app called Deco which allows them to stop any device registered from recieving WiFi. I listen to Spotify at night and therefore have to use my mobile data, like I am now. I am concerned about going over my data plan (2 gigs) too. I should also mention that they only started recently (a couple nights ago).Is there a way I can bypass Deco?
PS: Preferably no answers containing “well if you live under their roof then it’s their rules yadda yadda yadda” I just want to know if I can bypass it or not
