forced to buy an echo for new house. any suggestions?

my family is moving into a much bigger house than we used to have. we use amazon echos as an intercom system through the announcement feature. because our house is bigger, i’m being forced to get one myself for my room. i haven’t needed one for years because i use their app on my phone and i can see their announcements as a notification and i can also kill off most of its tracking by DNS. unfortunately my parents don’t understand this and are forcing me to get one. what can i do to limit its tracking?
