  • Sessions are managed with secure, time-limited JWT tokens
  • Multi-factor authentication (MFA) is available for all accounts

6. Data Retention

We retain your data for as long as your account is active. When you delete your account, we remove your personal data within 30 days, except where we are required to retain it for legal or legitimate business purposes.

Booking records may be retained for up to 12 months after account deletion for audit and compliance purposes, after which they are permanently deleted.

We use essential cookies to maintain your session and preferences. We do not use third-party tracking cookies. Analytics data is collected server-side without cookies where possible.

9. Third-Party Integrations

When you connect third-party services (Google, Microsoft, Zoom, Stripe, CRM systems), those services have their own privacy policies. We recommend reviewing their policies. We only request the minimum permissions necessary for our service to function.

Karlendar is not intended for use by children under 16 years of age. We do not knowingly collect personal data from children.

11. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the new policy on this page and updating the "Last updated" date. Continued use of our service after changes constitutes acceptance of the updated policy.
