Data Retention for Cookie Data
Session data associated with cookies is retained only for the duration specified in the tables above. Authentication sessions expire after 30 minutes of inactivity. Refresh tokens expire after 7 days. Upon expiration or logout, session data is invalidated and removed from our servers. Our data retention practices are governed by our internal Data Retention Policy.
Security of Cookie Data
All authentication cookies are configured with security best practices:
- HttpOnly: Prevents JavaScript access (mitigates XSS attacks)
- Secure: Only transmitted over HTTPS connections
- SameSite=Strict: Prevents cross-site request forgery
In the event of a security incident affecting session data, our Incident Response Plan governs notification, containment, and remediation procedures. See our GDPR Compliance page for details on our incident response commitments.
