+
+Pangolin collects anonymous usage telemetry to help us understand how the software is used and guide future improvements
+and feature development.
+
+## What We Collect
+
+The telemetry system collects **anonymous, aggregated data** about your Pangolin deployment. For example:
+
+* **System metrics**: Number of sites, users, resources, and clients
+* **Usage patterns**: Resource types, protocols, and SSO configurations
+* **Performance data**: Site traffic volumes and online status
+* **Deployment info**: App version and installation timestamp
+
+## Privacy & Anonymity
+
+**No personal information is ever collected or transmitted.** All data is:
+
+* **Anonymized**: Identifying info is hashed using SHA-256
+* **Non-identifying**: Cannot be used to identify specific users or organizations
+
+## Configuration
+
+You can control telemetry collection in your `config.yml`:
+
+```yaml  theme={null}
+app:
+  telemetry:
+    anonymous_usage: true  # Set to false to disable
+```
+
+## What This Helps
+
+Anonymous usage data helps us:
+
+* Identify popular features and usage patterns
+* Prioritize development efforts
+* Improve performance and reliability
+* Make Pangolin better for everyone
+
+If you have concerns about telemetry collection, you can disable it entirely by setting `anonymous_usage: false` in your
+configuration.
