4. Data Retention

Your data is retained as long as your account is active. You can export all your data via CSV at any time from Settings. Upon account deletion, all data is permanently removed within 30 days. Aggregated, anonymized usage statistics may be retained indefinitely for product improvement purposes.

5. Cookies and Tracking Technologies

We use the following cookies and tracking technologies:

  • Essential cookies: Required for authentication, session management, and security. These cannot be disabled.
  • Analytics cookies: Used by Google Analytics 4 (GA4), PostHog, and Microsoft Clarity to understand how visitors interact with Summitward. These collect anonymized usage data such as pages visited, features used, session duration, and interaction patterns (clicks, scrolls, and mouse movements).
  • Local storage: Used to store user preferences (e.g., dark mode, onboarding state) in your browser. This data never leaves your device.

You can opt out of analytics tracking by enabling “Do Not Track” in your browser settings or by using a browser extension that blocks analytics scripts. Disabling essential cookies may prevent you from using Summitward.

The Service is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that we have collected personal information from a child under 13 without parental consent, we will take steps to delete that information promptly. If you believe a child under 13 has provided us with personal information, please contact us at support@summitward.com.
