Gender Options and Data Collection for Vaccine Tracker App

Hello everyone,

I'm currently working on implementing a vaccine tracker and reminder feature for an application. As part of this feature, I plan to collect basic information about babies from their parents, such as name, gender, and date of birth, in order to create personalized profile cards and assist in tracking vaccinations.

My question is regarding the gender field: Is it acceptable to ask for only 'male' or 'female' as options, or should I include other gender options as well to ensure inclusivity? Additionally, considering that I'll be asking for gender and date of birth, I'm concerned about potential rejection of the app build by Apple. Can anyone provide insight into whether this could be an issue?

Thank you for your help and guidance!
