As the app mentioned is free, I would deduce that they try to turn the data about their users cycle into a monetary value. Is there research how certain periods of the cycle would affect women shopping behaviour (or behaviour in general)? I am asking this to understand how much value is in such information. Perhaps there are other aspects I am overlooking?

If someone stops having periods, that might be a sign they're pregnant. That's valuable to retailers (famously, some can spot when you're pregnant before even you know, by tracking purchases). Also, mood swings and specific cravings…
