Privacy Policy

Our Privacy Commitment

PERSIST is built with privacy-first principles. We analyze your work patterns without storing your personal data. Your calendar information is processed in real-time and never saved to our servers.

1. Information We Access

When you use PERSIST, we access:

• Google Account Information: Your name, email address, and profile picture
• Calendar Data: Event titles, times, durations, and attendee counts from your Google Calendar
• OAuth Tokens: Temporary authentication tokens to access your Google services

2. How We Use Your Information

We use your information exclusively to:

• Calculate your Adaptive Performance Index
• Measure your Cognitive Resilience score
• Assess your Sustainability Index
• Generate personalized work health insights
• Display your profile information in the application

All analysis happens in real-time during your session. We do not store historical data.

3. Data Storage and Security

Our security measures include:

• OAuth 2.0 secure authentication
• Encrypted session management via NextAuth.js
• HTTPS encryption for all data transmission
• No permanent data storage or databases
• Automatic session clearing on logout

4. Data Sharing

We do not share your data. Period.

Specifically, we do not:

• Sell your data to third parties
• Share your calendar information with anyone
• Use your data for advertising or marketing
• Allow any external access to your information
• Store data for analysis beyond your current session

5. Cookies and Tracking

We use minimal cookies solely for:

• Session Management: Encrypted session cookies to maintain your login state
• Preferences: Local storage for UI preferences (like onboarding completion)

We do not use analytics, tracking, or advertising cookies. We do not track your behavior across other websites.

6. Your Rights and Controls

You have complete control over your data:

• Access Control: Revoke our access anytime through Google Account settings
• Data Deletion: Sign out to immediately clear all session data
• Permissions: We only request read-only calendar access
• Transparency: See exactly what we calculate in real-time

7. Data Retention

Our data retention policy is simple:

• During Session: Data exists only in encrypted memory
• After Logout: All data is immediately cleared
• No Historical Storage: We don't keep any user data between sessions
• Browser Storage: Only stores non-personal preferences (like "onboarding seen")

8. Children's Privacy

PERSIST is not intended for users under 18 years of age. We do not knowingly collect information from children. The service is designed for professional work analysis.

9. Third-Party Services

We integrate with minimal third-party services:

• Google OAuth: For authentication and calendar access
• Vercel: For application hosting (they do not have access to your data)

These services have their own privacy policies. We recommend reviewing Google's privacy policy for information about how they handle your data.

10. Changes to Privacy Policy

We may update this Privacy Policy to reflect changes in our practices or for legal reasons. We will notify users of material changes by updating the "Effective Date" and, when appropriate, through in-app notifications.
