+## Telemetry
+
+Basic Memory collects anonymous usage statistics to help improve the software. This follows the [Homebrew model](https://docs.brew.sh/Analytics) - telemetry is on by default with easy opt-out.
+
+**What we collect:**
+- App version, Python version, OS, architecture
+- Feature usage (which MCP tools and CLI commands are used)
+- Error types (sanitized - no file paths or personal data)
+
+**What we NEVER collect:**
+- Note content, file names, or paths
+- Personal information
+- IP addresses
+
+**Opting out:**
+```bash
+# Disable telemetry
+basic-memory telemetry disable
+
+# Check status
+basic-memory telemetry status
+
+# Re-enable
+basic-memory telemetry enable
+```
+
+Or set the environment variable:
+```bash
+export BASIC_MEMORY_TELEMETRY_ENABLED=false
+```
+
+For more details, see the [Telemetry documentation](https://basicmemory.com/telemetry).
