Introduction
ApApps ("we," "our," or "us") operates the Cephra mobile application (the "Service"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application for migraine tracking and management.
Please read this Privacy Policy carefully. By using the Cephra application, you consent to the practices described in this policy.
Privacy First Approach: Cephra is designed with privacy as our top priority. All your health data stays on your device and is never transmitted to external servers. You maintain complete control over your sensitive health information.
Information We Collect
Health and Medical Information
Cephra is designed to help you track and manage your migraine episodes. The health information you may provide includes:
- Migraine Entry Data: Date, time, severity level, duration, notes about episodes
- Medication Information: Names, dosages, and types of rescue and preventive medications
- Symptom Data: Headache status, pain levels, and related symptoms
- Menstrual Cycle Data: Menstruation status (if enabled in settings)
- Work-Related Data: Information about work-induced migraines
- Triggers and Patterns: Data used for analysis and insights
Device and Usage Information
We may automatically collect certain information about your device and how you use the app:
- Device type, operating system, and version
- App version and usage statistics
- Crash reports and error logs (anonymized)
Information You Provide
- Settings and preferences within the app
- Export/import data when using CSV functionality
- Any feedback or support communications
Cloud Mode Information (Optional)
Email Address (Temporary Use Only) - Cloud Mode Only
- Collected when you log in to the app to receive a 6-digit verification code
- Sent securely to our backend via encrypted HTTPS
- Never stored in plain text in any database
- Used only to send a one-time code through Amazon Simple Email Service (SES)
- Automatically deleted within minutes after verification or expiration
Hashed User ID – Cloud Mode Only
- A hashed version of your email (using a private salt) is used to identify your account data in our database
- This value is anonymized, non-reversible, and used to associate your migraine data, medications, and preferences with you
- The hashing ensures your actual email is never stored alongside your health data
Cloud Storage Data
- AWS DynamoDB: Your migraine data, medications, tags, and user preferences are stored in Amazon Web Services DynamoDB
- Authentication: User authentication and session management through AWS services

- Anonymized analytics data (if you consent)
Cloud Mode
Since your health data can now be stored in the cloud:
- Your data may be processed and stored in countries other than your own
- We ensure appropriate safeguards are in place to protect your data in accordance with this Privacy Policy and applicable laws
- All data transfers use industry-standard encryption and security measures
Changes to This Privacy Policy
We may update this Privacy Policy from time to time. When we do:
- We will notify you through the app or other means
- The "Last Updated" date will be revised
- Continued use of the app constitutes acceptance of the updated policy

Data Security
Security Measures
We implement comprehensive security measures to protect your health data:
- Encryption: All data is encrypted in transit and at rest
- Authentication: Secure user authentication and session management
- Access Controls: Strict access controls for cloud data
- Regular Updates: Regular security updates and vulnerability assessments
- Privacy Protection: We do not store personally identifiable information on our servers. Only a hash of your email address is stored for authentication purposes, which cannot be used to identify you personally
Data Breach Notification
Due to our privacy-first approach, we do not store any personally identifiable information on our servers. The only data stored is a hash of your email address for authentication, which cannot be reversed to reveal your actual email. Therefore, in the unlikely event of a data breach, there would be no personally identifiable information at risk that would require notification under typical breach notification laws.
Your Responsibilities
- Device Security: Keep your device secure and use strong authentication
- Account Protection: Protect your account credentials and log out when not in use
- App Updates: Keep the app updated to benefit from security improvements
