Privacy Policy
Effective date: May 21, 2026
This policy applies to the Ovuly mobile application. It explains what app data Ovuly handles, where it is stored, and your rights. In short: your health data is stored securely in your iCloud account — never on Ovuly servers. We collect anonymized app usage statistics to improve the product, but we never sell data or access your personal health information.
1. What We Collect and What We Don't
There is no account system and no advertising tracker in the App. We never sell your data. We have zero access to your personal health information — your health and cycle data is stored securely in your iCloud account using end-to-end encryption, never on Ovuly servers.
We do collect anonymized app usage statistics through PostHog EU to understand how the App is used and to improve the product. All analytics data is processed and stored within the European Union. These statistics contain no personal identifiers, no health data, and no cycle information. Examples include which screens are visited and which features are used. See section 6 for details.
2. Data Stored on Your Device
The following data is stored on your device and synced securely via your iCloud account using end-to-end encryption. This data is not accessible to Ovuly or any third party.
| Data type | Purpose |
|---|---|
| Period & spotting logs | Cycle tracking and predictions |
| Symptoms & mood | Pattern recognition and daily logging |
| Journal notes | Personal notes you choose to record |
| Cycle settings (cycle length, period length) | Prediction accuracy |
| Notification preferences | Scheduling local reminders |
3. Apple Health (HealthKit)
With your explicit permission, the App may read data from Apple Health to enhance cycle insights, and write data to Apple Health so you can export your information for portability or use with other apps.
| Data type | Read | Write | Purpose |
|---|---|---|---|
| Menstrual flow | Yes | Yes | Read for cycle insights; write during export |
| Spotting | Yes | Yes | Read for cycle insights; write during export |
| Cervical mucus quality | Yes | Yes | Read for cycle insights; write during export |
| Wrist temperature | Yes | No | Phase predictions |
| Heart rate variability (HRV) | Yes | No | Cycle insights |
| Resting heart rate | Yes | No | Cycle insights |
| Sleep analysis | Yes | No | Wellness correlations |
All HealthKit data stays on your device and is governed by Apple's HealthKit privacy protections. You can grant or revoke access at any time in Settings > Health > Data Access & Devices.
We never access HealthKit data in the background, and we never transfer HealthKit data off your device or to any third party.
4. Subscriptions
Subscriptions are processed entirely by Apple through the App Store. We do not receive or store your payment information, Apple ID, or billing details. Apple's privacy policy governs the transaction data they handle.
5. Notifications
The App may send local notifications (period reminders, daily log reminders, fertile window alerts) if you enable them. These notifications are scheduled on-device and do not involve any external push notification service or server.
6. Third-Party Services
The App uses PostHog EUto collect anonymized app usage statistics. All analytics data is processed and stored on PostHog's EU servers (Frankfurt, Germany). This data includes general usage patterns such as screen views and feature interactions. It does not include any personal identifiers, health data, cycle information, or symptom logs. We use this data solely to improve the App.
The App does not integrate any advertising or ad-tracking services. The only other external communication is with Apple's StoreKit framework for subscription management.
7. Data Retention & Deletion
Since all data is stored locally on your device, you have full control:
- Delete individual entries within the App at any time.
- Delete all App data by uninstalling the App from your device.
- Revoke HealthKit accessin your device's Health settings.
We cannot delete your data for you because we do not have access to it.
8. Children's Privacy
The App is not directed at children under 13 (or the applicable minimum age in your jurisdiction). We do not knowingly collect data from children. If you believe a child is using the App inappropriately, please contact us.
9. Security
Your health data benefits from the security features built into iOS, including device encryption and biometric lock. Health and cycle data is stored only on your device and in your iCloud account — it is never transmitted to Ovuly servers. Anonymized usage statistics sent to PostHog EU contain no personal or health information.
10. Changes to This Policy
We may update this Privacy Policy from time to time. The updated version will be posted at this URL with a revised effective date. We encourage you to review it periodically.
11. Your Rights
Because we do not collect or store your personal data, traditional data-subject rights (access, portability, erasure) are already satisfied. Your data is entirely in your possession on your device. If you have questions about exercising your rights, contact us.
