Privacy Policy

Last updated: October 15, 2026

What the app works with

• Your profile. Birth year, date of your last period, how regular your cycles were, what bothers you most. Stored only in the app's local storage on your device, used solely to estimate your stage and explain your days.
• Check-ins. Symptom scores, triggers, period flow, notes, medication and HRT entries. Local only.
• Apple Health (iOS) and Health Connect (Android). With your permission the app reads sleep, heart rate variability, resting heart rate, wrist or skin temperature and menstrual flow for the last few weeks, to compare each night with your own baseline. This data is read on your device, summarised per day, kept in the app's local storage and never transmitted anywhere. It is not used for advertising, marketing, or any purpose other than showing you your own explanations. It is never sold or shared with third parties. You can revoke access at any time in the Health app (iOS) or Health Connect settings (Android); the app keeps working without it.
• Notifications. The optional evening reminder is scheduled locally on your device. No push servers.
• Share card and PDF report. Rendered on your device and handed to the system share sheet. Nothing leaves the phone unless you choose a destination. The share card contains no name, dates or notes.
• Backups. If you export a backup, the file is yours — MenoShift never uploads it.
• Purchases. Handled by Apple or Google. Subscription status is verified through RevenueCat using an anonymous, randomly generated identifier; no personal or health data is part of it. We never see payment details.
• Anonymous usage counters. To see where the app is confusing, it counts how often screens are opened, how many days it was used, how far onboarding got, and how often the paywall, articles, share card and PDF report were opened. These numbers are attached to the same anonymous RevenueCat identifier. They contain no symptoms, cycle dates, health readings, notes, names or contact details, are not used for advertising or tracking, and are not shared with anyone.

What the app does not do

• No accounts, no sign-in
• No analytics, no tracking, no advertising SDKs
• No third-party data sharing (there is nothing to share)
• No network transmission of your personal or health data

Data deletion

Deleting the app deletes everything you entered and everything it derived from Apple Health or Health Connect — it all lives only on your phone. The one record that exists outside your phone is the anonymous purchase record held by RevenueCat; you can have it deleted by emailing us. Step-by-step instructions, what is deleted and how long each item is kept: Delete your data.
