Privacy Policy — CycleMe

1.1 Health & Cycle Data (Provided by You)

• Menstrual cycle dates, period length, and flow intensity
• Symptoms (cramps, headache, bloating, fatigue, mood changes, breast tenderness, acne, back pain, nausea, and others) with severity ratings
• Contraception method and daily tracking (e.g., pill taken/skipped)
• Pregnancy status, start/end dates, pregnancy outcome, and postpartum tracking
• Cycle regularity and default cycle/period length preferences
• Notes attached to symptoms or cycle entries

All health and cycle data is stored locally on your device using an on-device database. It is never sent to our servers — we do not operate any servers that receive your health data.

1.2 Apple HealthKit Data

With your explicit permission, the App can:

• Read menstrual flow, cervical mucus quality, ovulation test results, intermenstrual bleeding, sexual activity, contraceptive use, and symptoms (headache, abdominal cramps, bloating, mood changes, fatigue, breast pain, acne, lower back pain, nausea) from Apple Health.
• Write period flow, symptoms, and contraception data back to Apple Health.

HealthKit data is governed by Apple's HealthKit policies and is never shared with third parties, used for advertising, or transferred off your device by us.

1.3 iCloud Backup Data (Pro Feature, Optional)

If you are a CycleMe Pro subscriber and choose to enable iCloud backup, your cycle data (cycle records, symptoms, contraception entries, and user profile) is backed up to your personal iCloud account via Apple CloudKit. This data is stored in your private CloudKit database — only you can access it. We cannot read, access, or retrieve your iCloud backup data.

1.4 Partner Sharing Data (Optional)

If you use the Partner Sharing feature, limited cycle information is shared with your connected partner(s) via Apple CloudKit. You control what is shared through configurable share levels:

• Phases — current cycle phase only
• Predictions — adds estimated next period date
• Fertility Data — adds fertile window dates
• Contraception — adds contraception method and status
• All — all available cycle snapshot data

Shared data includes: current cycle day, cycle phase, predicted next period, fertile window dates, pregnancy status (if applicable), and contraception status (if selected). Shared data does not include raw symptom logs, severity ratings, or personal notes.

You can pause sharing, change share levels, or revoke partner access at any time. Partners connect via a temporary 6-character invite code that expires after 24 hours.

1.5 Analytics Data

We use Mixpanel to collect anonymous usage analytics to help us improve the App. Analytics events include:

• App opens and onboarding steps
• Feature usage (e.g., “symptom logged”, “pill taken”) — event names and counts only, not the actual health data content
• Subscription events (paywall viewed, purchase completed/failed)
• Settings changes (e.g., notifications toggled, discreet mode toggled)

We also store basic user properties: user mode (cycle owner or partner), app version, subscription plan, and premium status.

Analytics data does not include your name, email address, specific health data values, symptom details, cycle dates, or any personally identifiable information.

For more information, see Mixpanel's Privacy Policy.

1.6 Subscription Data

We use RevenueCat to manage in-app subscriptions and purchases. RevenueCat processes your subscription status, entitlements, and purchase transactions. RevenueCat does not receive your health data.

For more information, see RevenueCat's Privacy Policy.

1.7 Device-Level Data

The App stores the following locally on your device:

• App preferences (onboarding status, discreet mode, notification settings)
• Subscription status cache (stored in the iOS Keychain)
• App lock passcode (stored securely in the iOS Keychain)
• An encryption key for data protection (stored in the iOS Keychain)

This data never leaves your device.
