5. The Application may store and process Personal Data. Please refer to Our Privacy Policy for details. It is Your responsibility to maintain the security of your phone and access to the Application. The Company strongly advises against jailbreaking or rooting your phone, which involves removing software restrictions and limitations imposed by the official operating system of your Device.
