+
+    Your uploaded data is not stored permanently, and it is not accessible to other users.
+
+    Each session is isolated, meaning your data is only available during your active session and is automatically cleared when the session ends (including temporal logs).
+
+    Vivid Volcano does not collect, store, or share any uploaded files or analysis results. It collects non-sensitive telemetry data - number of sessions, analyses performed, time of sessions etc....
+
+    For your safety, I recommend not uploading highly sensitive data (ex. not blinded patients data) , as the app is hosted on a public server without authentication. For sensitive data you can
+    use this installer to install the app localy or in your own cloud container.
