App analytics vs sensitive health data

A practical guide to the difference between app analytics and sensitive health data, and why that distinction matters in cycle tracking apps.

Written by Luna Team. Luna offers educational guidance, not diagnosis or contraception.

Not all app data is the same.

There is a difference between basic analytics and sensitive health data. This difference matters.

Pattern Snapshot

The line to look for

Add short labeled pattern notes in MDX to populate this summary.

A strong privacy model makes this boundary clear in both product design and policy language.

What app analytics usually means

Analytics can include:

  • app usage
  • clicks and navigation
  • performance data

This is often used to improve the product.

What sensitive health data includes

In a cycle tracking app, this can include:

  • cycle dates
  • symptoms
  • mood
  • personal notes

This is deeply personal.

Why the distinction matters

Some apps treat all data the same. Others separate them.

If sensitive data is handled like analytics, it can be:

  • shared
  • used for targeting
  • exposed in ways you don't expect

What to look for

  • clear separation between analytics and health data
  • no data selling
  • simple control over your data

If this isn't clear, it's a risk.

How this fits into privacy

This connects to how apps make money.

Final thought

Privacy is not just about storage. It's about how data is treated.
