What data ASP.NET collects
Your privacy policy must disclose each of the following data types when you use ASP.NET.
When does ASP.NET trigger privacy obligations?
When ASP.NET Triggers Obligations
Adding ASP.NET to your application automatically sets the `ASP.NET_SessionId` cookie on user browsers. This single act triggers privacy obligations in nearly all jurisdictions:
GDPR (EEA users): The moment ASP.NET sets a session cookie, you are processing personal data (the session identifier and any user activity bound to it). GDPR Article 6 requires a lawful basis—typically "consent" or "legitimate interest." The ePrivacy Directive Article 5(3) is stricter: non-essential cookies require *prior* explicit consent before the cookie is set. The `ASP.NET_SessionId` is necessary for session management, but many frameworks set additional tracking cookies alongside it; you must distinguish necessary from unnecessary.
CCPA (California users): Session data collection triggers disclosure obligations under CCPA Section 1798.100 if you store identifiable session information. You must disclose what session data you collect, categories of sources, and purposes in your privacy notice.
First concrete step: Audit whether your ASP.NET application sets *only* the session cookie or additional cookies (analytics, advertising pixels). Document the purpose of each. If you serve EEA users, implement a consent management system that blocks non-essential cookies until consent is given. If you serve California users, update your privacy policy to disclose session data collection before launch.
