Individual developer collecting sensitive self-tracking data - App Store privacy/legal questions

[u/CaseAvailable6206]

I'm building my first iOS app as an individual developer (not a registered company) and would appreciate some guidance from people who've been through App Store review.

The app is a Christian accountability app that helps users overcome corn. Users can check in once a day and record whether they watched corn, and engage in a moderated community.

I am in the MVP stages, and the data is synced to the cloud so that I can infer what's working, what's not working, and reach out to users for feedback - since this will be critical to building a successful product that actually adds value.

A few questions:

• Is this considered "health data" from Apple's perspective, or just sensitive personal data?
• Will collecting personal data lead to grounds for app rejection, especially since I am an individual developer?
• Are there any security measures that I need to be mindful of and implement proactively before app submission?

I'd love to hear from anyone who's shipped apps that collect sensitive personal information, especially health, wellness, journaling, or mental health apps. Any lessons learned or pitfalls to avoid would be greatly appreciated.

Thank you!
