+ * PRIVACY NOTICE:
+ * - Telemetry is enabled by default to help us improve the product
+ * - You can disable telemetry via:
+ *   1. Settings UI > Privacy tab > Toggle off "Allow anonymous telemetry"
+ *   2. Setting NEXT_TELEMETRY_DISABLED=1 environment variable
+ *
+ * This file allows you to configure OpenTelemetry collection for your
+ * Sim instance. If you've forked the repository, you can modify
+ * this file to send telemetry to your own collector.
+ *
+ * We only collect anonymous usage data to improve the product:
+ * - Feature usage statistics
+ * - Error rates (always captured)
+ * - Performance metrics (sampled at 10%)
+ * - AI/LLM operation traces (always captured for workflows)
+ *
+ * We NEVER collect:
+ * - Personal information
+ * - Workflow content or outputs
+ * - API keys or tokens
+ * - IP addresses or geolocation data
