<prompt> Human: So after I graduated high school I got a job and opened my first bank account. Its in my name only, my parents have no connection to it whatsoever. At my first job I wasnt making much nor getting many hours so I switched jobs and started working 40 hours a week, making a bit more. I still live at home so most of my earnings have went into my investment portfolio which has accrued around 10-2037; on top of my savings.The problem currently is that supposedly my parents know someone who works at the bank who is telling them how much Im makingtransferring. Whenever I move money from my brokerage to my bank account I can be sure my parents will ask, how did you get x,xxx? Honestly this isnt too concerning. Im not doing anything illegal, and I like to keep them guessing. The only part that angers me is that I did not give anyone permission to see this information. Am I wrong to assume that this somehow goes against the banks customer privacy policy?Edit: As people have noted there are many ways they could be seeing my transactions. A popular answer is paper statements, but I have them completely off. Though there are still a plethora of ways which are entirely possible.As for why I dont ask them how they know what Im doing on my bank account. They flat out told me they are getting their information from a bank teller. They said they are notified of large transaction amounts. I am the one suspicious of this, because as many people have stated this is highly illegal. However, even if this is the case I dont want to jeopardize anything over this. Im honestly not the type to go to the bank and make a big fuss, even though it does anger me. Im sure everyone involved just wants to do whats best. Ill just switch banks and forget about it. Thanks all! Assistant: If theyre not authorized on the account then it definitely sounds like an illegal privacy violation, whether theyre your parents or not. You could take it up with the bank and escalate some kind of claim or you could just change banks. You may want to verify 100 that your parents dont somehow have permissions on the account or that they arent snooping on your computerbank statements I dont know what your parents are likeHuman: Im wondering if they guessed my bank login info. I use Chase, and theres no real way to monitor what devicesIPs access your account.Edit: Since this post continues to grow, Ill edit this and clarify that you can in fact view the devices which access your account.  <response>: Actually you can, in the app go to my settings then at the bottom you can see my devices. It will show you any devices that logged into your account in the past 90 days.
