The big idea
Period tracking apps use AI to predict your cycle, suggest health insights, even predict ovulation. Useful for many. But the data is private health data — and some apps have shared it without users knowing.
Some examples
Useful: predicting next period, tracking PMS symptoms, learning your cycle.
Risky: apps that share data with advertisers (some have, some have stopped).
Risky: in some US states, period data has been used in legal cases.
Better: pick apps that explicitly say they do not share data and have clear privacy policies.
Try it!
If you use a period tracker, look at its privacy policy. Does it share data with third parties? Decide if you are comfortable.
