Your Brain, Your Bones, and Your Period Tracker Just Sold Your Data

Key Takeaways

• ✦A new study found that women who used hormone therapy had roughly 35% lower Alzheimer's risk — but this is observational research, not a clinical trial, and the result does not mean HRT prevents Alzheimer's.
• ✦A systematic review of multiple studies found that high-intensity and strength training does increase bone density in postmenopausal women, though the effect sizes were described as small — real, but not dramatic.
• ✦The type of exercise matters: impact training (like jumping) and strength training both showed benefits for bone density, and the research supports combining them rather than choosing one.
• ✦Multiple menopause apps have sold users' intimate health data — including symptom logs, cycle history, and other private details — often without clear disclosure, and the practice is reportedly ongoing.
• ✦If you use a menopause or period tracking app, it is worth checking its privacy policy specifically for language about data sharing with third parties or "partners."
