+## SigNoz telemetry
+
+After the user opts in, Gitty sends privacy-filtered product events and technical errors as OTLP/HTTP JSON logs. Every Git/Tauri command is also captured as a trace span with its command name, duration and success state, but without command arguments or results. CPU utilization and resident memory usage of the Gitty process are sampled every 30 seconds and exported as OpenTelemetry gauges. The default endpoints are `https://telemetry.cbsk-tech.de/v1/logs`, `https://telemetry.cbsk-tech.de/v1/traces`, and `https://telemetry.cbsk-tech.de/v1/metrics`.
+
+The SigNoz reverse proxy must forward all three paths to the Collector's OTLP/HTTP receiver (normally port `4318`). For development or a separate collector hostname, set `GITTY_OTLP_LOGS_ENDPOINT`, `GITTY_OTLP_TRACES_ENDPOINT`, and `GITTY_OTLP_METRICS_ENDPOINT` to the full signal URLs before starting Gitty.
+
+Telemetry is non-blocking, bounded, disabled until consent is stored, and never includes repository paths, remote URLs, branch names, commit messages, diffs, file names, credentials, source code, URLs, or email addresses.
