Period app privacy: which cycle data should be protected first?
Cycle data is intimate. A serious app should limit collection, protect sharing, and explain its practices clearly.
Cycle data is sensitive
Period dates, symptoms, mood, pain, and fertility estimates say a lot about daily life. They should be treated with more care than ordinary app preferences.
Before using an app, check what it collects, why it collects it, and whether it shares data with third parties.
Sharing must be voluntary
In Luteal, partner sharing is optional. You choose to invite someone, and access can be removed. No one should get a view into your cycle without your consent.
Less unnecessary data
A cycle tracking app does not need your contacts, precise location, or photos to work. Data minimization is a real quality signal.
