sCycle Privacy Policy

1. Introduction

Welcome to the Privacy Policy for the sCycle app ("we", "us", or "our"). sCycle is a private period tracking app designed to help you understand your menstrual cycle while keeping your personal health data completely secure and private.

This Privacy Policy explains how we handle your data when you use our app. Please read this policy carefully to understand how we treat your sensitive health information.

2. Data Collection

Local Storage Only: sCycle is a privacy-first period tracking app. All your health data is stored exclusively on your device using encrypted local storage and is never transmitted to external servers or cloud services.

Health Data We Store Locally

The app collects and stores the following health information that you actively enter:

• Menstrual cycle dates (period start/end dates)
• Daily period logs (flow intensity, symptoms, pain levels)
• Personal notes and cycle observations
• App settings and preferences (notifications, themes, language)
• Biometric authentication settings (if enabled)

We use the following secure local storage technologies:

• SQLCipher: Military-grade AES-256 encryption for your health data
• Flutter Secure Storage: For storing encryption keys and sensitive settings
• Shared Preferences: For non-sensitive app preferences

What We DO NOT Do

• We DO NOT collect any personal identifying information
• We DO NOT transmit your health data to our servers or any third party
• We DO NOT sell, share, or analyze your personal health data
• We DO NOT display advertisements or use tracking technologies
• We DO NOT use analytics tools or external monitoring services

3. App Permissions

The sCycle app requires only necessary permissions to function properly:

• Secure Storage Access: To store your encrypted health data locally on your device
• Biometric Authentication: To protect your data with Face ID, Touch ID, or fingerprint (optional)
• Notifications: To send you optional period predictions and cycle reminders (only if enabled)
• File Access (iOS/Android): To enable data export/import for backup purposes (user-initiated only)
• Camera/Photo Library (iOS): For potential future features like photo documentation (not currently used)

4. Data Sharing

sCycle is designed with privacy as the core principle - we do not automatically share any data.

Manual Data Export

The app provides you with complete control over your data through manual export features:

• Export your cycle data for backup or transfer to another device
• Share individual cycle insights or summaries (your choice)
• Generate reports for healthcare providers (if you choose)

All sharing is explicit, user-initiated, and you maintain full control over what information is shared and with whom.

5. Data Security

Your menstrual health data is highly sensitive, and we implement multiple layers of security to protect it:
