This Privacy Policy explains how ZY App Studio ("we," "us," or "our") handles your information when you use the Period Tracker mobile application (the "App"). We believe that intimate personal health data belongs exclusively to you. We are committed to protecting your privacy in accordance with applicable data protection laws, including the Malaysian Personal Data Protection Act (PDPA) 2010 and international privacy standards.
1. Information We Collect & On-Device Storage
The App is built with a Privacy-First Architecture. We do not operate external user accounts, cloud databases, or remote tracking servers for your personal health records.
Personal Health Data (Local Storage Only): All information you log within the App—including period dates, cycle predictions, fertile windows, symptoms (e.g., cramps, headaches, fatigue), flow intensity, mood notes, and intimacy logs—is stored exclusively on your local device using encrypted local storage (
SharedPreferences/SQLite). This data is never transmitted to, stored on, or backed up to our servers.Passcode & Biometric Authentication: If you enable app lock, your passcode or biometric credentials (fingerprint/Face ID) are managed entirely by your device’s native operating system security framework. We never see, collect, or store your security credentials.
App Settings & Preferences: Your local app settings—such as notifications, reminder times, preferred calendar start days, language selection, and screen-lock timers—are saved locally on your device.
Diagnostic & Technical Data: We may automatically process non-personally identifiable technical information (e.g., app crash logs, device model, and operating system version) strictly to identify bugs, optimize performance, and improve app stability. This data contains no health or personal tracking information.
2. How We Use Your Information
Because your health data remains on your device, it is processed locally to strictly deliver core app functionality:
Deliver Core Features: Calculate period forecasts, predict fertile windows, generate cycle statistics, render calendar views, and display relevant health tips or insights.
Maintain App Security: Enforce app lock timers, biometric authentication, and optional screenshot/screen recording blocking to safeguard your screen from unauthorized local viewing.
App Maintenance: Analyze anonymized crash logs to fix technical glitches and optimize battery efficiency across different mobile devices.
3. Disclosure & Sharing of Your Information
We do not sell, rent, trade, lease, or broadcast your personal health data, cycle logs, or daily symptoms.
Your health data stays entirely on your device. Non-sensitive technical diagnostics may only be processed in the following restricted scenarios:
Third-Party Infrastructure Providers: We may use trusted, privacy-compliant diagnostic services (such as Google Play Crashlytics) solely to receive anonymized crash reports and technical performance metrics.
Legal Requirements: If required by applicable laws, valid legal processes, or enforceable governmental requests, though we note that because we do not store your health logs on remote servers, we possess no user health data to provide.
Business Transfers: In the event of a merger, acquisition, or sale of assets, anonymized app stability metrics may be transferred as part of standard business operations.
4. Third-Party Links & Content
The App may feature educational health articles and audio guides ("Insights"). Viewing this content is processed locally or via secure content delivery networks (CDNs). These informational materials do not track, profile, or link your reading history to your real-world identity.
5. Your Privacy Rights & Full Control
Under applicable privacy laws, including the Malaysian PDPA, you retain total ownership and control over your health information:
Data Deletion & Reset: You have complete control over your logged data. You can edit, clear, or reset your period history and logs at any time directly within the App settings, or by clearing the App's storage via your device settings (Settings > Apps > Period Tracker > Storage > Clear Storage).
Uninstalling the App: Deleting or uninstalling the App from your device permanently and irreversibly erases all locally saved period logs, symptom history, and app preferences.
Permission Management: You can grant, modify, or revoke permissions—such as Notifications for period reminders—at any time via your device settings (Settings > Apps > Period Tracker > Permissions).
6. Security Measures
We implement industry-standard technical security practices to safeguard your privacy:
On-Device Isolation: Your health records never leave your physical device.
Screen Protection: Optional settings allow you to block screenshots and screen recordings to prevent unauthorized screen captures.
Local Authentication: Optional biometric and passcode security layers keep your logs safe from anyone physically accessing your phone.
