Mensy Privacy Policy

Effective and last updated: June 6, 2026 App: Mensy (App Store ID: 6769362459, Bundle ID: com.pleyra.mensy) Data controller / Developer: Pleyra Contact: privacy@pleyra.com (privacy and data requests) · support@pleyra.com (technical support) · hello@pleyra.com (general)


At a glance


1. Scope of this policy

This Privacy Policy applies to all Mensy components, including the Mensy iOS app, the Apple Watch companion, and the Home Screen widget. By using Mensy you accept the data practices described here. The data controller is Pleyra; our postal address is available on request from privacy@pleyra.com.

2. Data we process

All personal data Mensy processes is either entered by you or, with your permission, read from Apple systems. Pleyra cannot access this data.

2.1. Data stored on your device

2.2. Sign in with Apple data

You can use Mensy as a Guest (providing no identity at all). Optionally, you may use Sign in with Apple. In that case the user identifier provided by Apple and (only on first sign-in, and only if you allow it) your name and email address are stored only in local storage on your device. This information is never sent to any Pleyra server and is not included in iCloud sync. You can remove it from the device at any time using "Sign Out".

2.3. Apple Health (HealthKit) data

If you explicitly grant permission, Mensy reads the following from Apple Health:

And writes only the following to Apple Health:

Apple Health data is processed only on your device, remains in the Apple Health store, and is never sent to any server. Mensy does not use Apple Health data for advertising, marketing, or user profiling, and does not share or sell it. HealthKit permission is entirely optional; if you decline, the app continues to work with all of its core features.

2.4. Device permissions

Mensy requests the following permissions only when you use the related feature:

3. Where your data is stored

3.1. Your device

Data is stored primarily on your device (iOS UserDefaults and the app group group.com.pleyra.mensy); the profile photo and journal images are kept in the app's own file area. Device encryption (your passcode / Face ID / Touch ID) protects this data.

3.2. Your own iCloud account (optional sync)

If you use more than one device with the same Apple ID, your cycle, symptom, profile, pregnancy, and PMOS data are synced between your devices through your own iCloud account (Apple iCloud Key-Value store, NSUbiquitousKeyValueStore). This sync:

If you are not signed in to iCloud or iCloud Drive/sync is off, all data stays only on your device. Premium trial status is stored in the iCloud Keychain to prevent repeated free trials.

3.3. Pleyra servers

There are none. Pleyra operates no backend server and does not transfer your personal data to its own systems.

4. Third parties and network connections

Mensy uses no third-party advertising, analytics, crash-reporting, or marketing services. Only the following connections apply:

Tracking: Mensy does not track you. The app's privacy manifest declares NSPrivacyTracking = false; therefore no App Tracking Transparency (ATT) prompt is shown.

5. Purposes and legal basis

Your data is processed solely to provide the app's functionality: personalized cycle analysis and phase predictions, PMOS type determination and guidance, reminders, daily recommendations, and (only when you request it, generated only on your device) a doctor PDF report.

Under GDPR and Türkiye's KVKK, menstrual/reproductive-health data is considered special category (sensitive) personal data. Mensy processes this data only with your explicit consent and on your device (GDPR Art. 6(1)(a) and 9(2)(a); KVKK Art. 6). You may withdraw your consent and delete your data at any time.

6. Data sharing and selling

Pleyra does not share, sell, or rent your personal data to any third party. Because Pleyra has no access to your data, there is no transfer for advertising or data-brokerage purposes. The limited processing involving Apple is only what is required for the platform services described above (iCloud sync, purchases, HealthKit) to function.

7. Retention

Your data stays on your device (and in your iCloud account, if applicable) until you delete it. Removing the app deletes the local data on the device. For data synced in iCloud, we recommend using the in-app "Delete All My Data" function (Section 8).

8. Your rights

Under GDPR and KVKK Art. 11 you have the rights of access, rectification, erasure, restriction of processing, objection, data portability, and withdrawal of consent. Because your data lives on your device, you can exercise most of these directly within the app:

You may also exercise your rights by writing to privacy@pleyra.com, and you have the right to lodge a complaint with your local data protection authority (in Türkiye, the Personal Data Protection Authority / KVKK).

9. Security

Data is encrypted at the device level (iOS device encryption and, where appropriate, the Keychain). iCloud sync is provided by Apple, encrypted in transit and at rest. Because we operate no accounts or server infrastructure, there is no central database to breach. No system is 100% secure, but Mensy is designed around data minimization.

10. Children's privacy

In line with its App Store age rating, Mensy is intended for users aged 16 and older. It is not directed to children under 13, and we do not knowingly collect data from children under 13. If you are under 18, you should use Mensy with the consent and involvement of a parent or guardian. If you believe a child under 13 has provided us with data, contact privacy@pleyra.com.

11. International data transfers

Pleyra does not transfer your data to its own servers. When you use iCloud sync, your data is processed in Apple's data centers under Apple's privacy and transfer policies, which may occur in different regions depending on your country.

12. Purchases

Mensy Premium is a one-time purchase (details in the Terms of Use). All payments are processed through the Apple App Store. Pleyra never sees or stores any payment information (card number, billing address, etc.). Apple links the purchase to your Apple ID, subject to Apple's privacy policy.

13. Medical disclaimer

Mensy is not a medical device. The content, calculations, and analyses it provides (including the PMOS quiz, HOMA-IR, Ferriman-Gallwey, and anomaly detection) are for informational and educational purposes only and are not a substitute for medical diagnosis or treatment. Mensy does not recommend prescriptions. Always consult a qualified healthcare professional for health decisions. In an emergency, call your local emergency number.

14. Changes

We may update this policy from time to time. Material changes are shared via in-app notification, and the current version is always published on this page with the date above.
