This will help us provide you with improved service and a better user experience. - We collect your date of birth (year, month, and day) to verify if you are a minor. Our platform enforces segregated interaction environments between minor and adult accounts. This ensures legal privacy protection while delivering age-appropriate learning content and carefully moderated social features. - We collect your gender information to help users filter suitable language exchange partners based on personal preferences. Some users prefer to communicate with language partners of the same gender, which is a core feature of our app. - We will collect your mobile phone number to verify your user information. Mobile phone numbers are sensitive information, and the purpose of collecting your mobile phone number is to meet the online real-name system requirements of relevant laws and regulations.
