How Much Data Have You Shared with Your Period Tracker?

A self-audit to estimate how much personal and reproductive health data your period tracking app has collected and potentially shared with third parties.

Every time you open your period tracker, you're generating data. Some of that data is what you deliberately enter. Some of it is collected automatically. And some of it has been shared with companies you've never heard of. This audit walks you through the categories of data your app may have collected, so you can estimate your total exposure. Question 1: How Long Have You Been Using Your App? Time equals data volume. Option A: Less than three months. Limited history. Your exposure is relatively small, but the data collection infrastructure has been active since day one. Option B: Three months to one year.

Multi year data reveals fertility patterns, health changes, and long term trends. Duration matters because even if the app collects limited data per session, accumulation over months builds a detailed picture. Question 2: What Have You Manually Entered? Check your app for which data fields you've used. Common categories include: Option A: Period dates only. Minimum manual input. Still reveals cycle length,
