+# Tracking    
+
+:::tip
+ToolJet does not store any data fetched from the datasources. ToolJet acts as a proxy and the data from datasources is sent to the client application without storing.
+:::
+
+## Server
+
+:::tip
+Self-hosted version of ToolJet pings our server to fetch latest product updates every 24 hours. You can disable this by setting the value of `CHECK_FOR_UPDATES` environment variable to `0`. This feature is enabled by default.
+:::
+
+## Client 
+
+ToolJet tracks anonymous usage data such as page loads and clicks. ToolJet tracks only the events and doesn't capture data from datasources.
+
+Tracking can be disabled by setting the value environment variable `ENABLE_TRACKING` to `0`.
