4. Authentication

5. Third-party services
We use the following third-party services:
- Clerk — authentication and session management

Each provider has their own privacy policy. We share only the minimum data necessary for each service to function.
6. Data retention & deletion
We retain your account and practice data for as long as your account is active. You may request deletion of your account and all associated data at any time. See our Data Deletion Policy for full instructions, or email us at privacy@kartacoach.com.

Depending on your location, you may have the right to:

- Data portability
To exercise any of these rights, email us at privacy@kartacoach.com.
8. Cookies
We use essential cookies required for authentication and session management. Analytics cookies (PostHog) are used to understand how the platform is used — these are anonymised and do not identify you personally.
