Can my parents legally control my phone usage and lock it?

Question

I am 21 years old and live with my parents, who pay for my phone. They use the app Quistodio to monitor my phone usage and can lock my phone completely or restrict it to select apps. I believe I am listed as a user on their phone plan. I have offered to contribute financially, but my mother doesn't seem to consider my input. Attempts to discuss this result in emotional responses, and they justify locking my phone to help regulate my sleep schedule, which negatively impacts my progress. I also pay for certain apps on my phone. Can my parents legally lock down my phone and control app usage in this manner?

From a legal perspective, your situation involves property rights since your parents own and pay for the phone service. When someone owns a device and pays for the service, they typically have the legal right to control how that property is used, even if the user is an adult. This applies to the physical device and the service plan regardless of your age. 
 
However, you might have some rights regarding the apps you've personally purchased. Those digital purchases could be considered your property, though accessing them still requires using the device your parents control. Your best approach would be to work toward financial independence by getting your own phone plan, which would give you complete control over your device usage. 
 
In the meantime, try having a calm, practical conversation with your parents about reasonable boundaries. Focus on how phone restrictions affect your progress and development as a young adult rather than making it about control. Consider writing down your thoughts beforehand to keep the discussion from becoming emotional, and propose a gradual transition plan toward digital independence that acknowledges their concerns while respecting your adult status.
