Privacy Policy

Information We Collect

Blood Type Personality can be used without creating an account, and we do not collect personal identifiers such as your name, email, or birth date. The blood type you pick is processed in the browser only and is not sent to or stored on our servers. We aggregate only anonymous usage statistics such as visits and shares.

Browser Storage

The blood type you pick is stored only in your browser's localStorage so you do not have to choose it again. It remains on your device and is used only to show your blood type result.
