4. How We Share Your Information

We do not sell, rent, or trade your personal information to third parties. We may share your information in the following limited circumstances:

These providers are contractually obligated to use your information only to provide services to us.
  • Analytics: We may use analytics services (such as PostHog or similar) to understand usage patterns. These services may collect anonymized or aggregated data.
  • Legal requirements: We may disclose your information if required by law, regulation, legal process, or governmental request, or if we believe disclosure is necessary to protect our rights, your safety, or the safety of others.
  • Business transfers: If GammaLens LLC is involved in a merger, acquisition, or sale of assets, your information may be transferred as part of that transaction. We will notify you via email or prominent notice on the Service before your information is transferred and becomes subject to a different privacy policy.

5. Data Retention

We retain your personal information for as long as your account is active or as needed to provide you with the Service. If you delete your account, we will delete or anonymize your personal information within 30 days, except where we are required to retain it for legal, accounting, or compliance purposes.

Usage data and analytics may be retained in anonymized or aggregated form indefinitely for product improvement purposes.

6. Data Security

We implement reasonable technical and organizational measures to protect your personal information against unauthorized access, alteration, disclosure, or destruction. These measures include encryption of data in transit (TLS/SSL), hashed password storage, access controls, and regular security reviews.

However, no method of transmission over the internet or electronic storage is 100% secure. We cannot guarantee absolute security of your information.

7. Cookies and Tracking Technologies

We use the following types of cookies:

  • Essential cookies: Required for the Service to function (authentication, session management). These cannot be disabled.
  • Preference cookies: Remember your settings and preferences (theme, layout, selected tickers).
  • Analytics cookies: Help us understand how users interact with the Service. These collect anonymized data about page visits and feature usage.

We do not use advertising cookies or allow third-party ad networks to place cookies on the Service. You can control cookie settings through your browser preferences. Disabling essential cookies may affect the functionality of the Service.
