Privacy Policy

Last updated: March 2026

Overview

Skills Trace is designed with privacy as a core principle. Our detection engine operates in read-only mode and never logs prompt content. We collect only skill identity metadata — the minimum information needed to provide runtime observability for AI capabilities.

Data Collection

When Skills Trace detects a skill in an LLM request payload, it emits a telemetry event containing:

  • Skill identifier (e.g., skill://namespace/name@version)
  • Detection method and confidence score
  • Timestamp
  • Tenant identifier
  • Model identifier and token usage counts

Skills Trace does not collect:

  • Prompt content or user messages
  • LLM responses or completions
  • Personal identifying information
  • API keys or credentials

Data Usage

Telemetry data is used exclusively to provide the Skills Trace service: usage analytics, cost attribution, drift detection, and risk monitoring. We do not sell, share, or use your telemetry data for advertising, model training, or any purpose unrelated to delivering the Skills Trace service.

Data Retention

Telemetry events are retained for one year by default. Pre-aggregated metrics (hourly and daily rollups) may be retained longer for trend analysis. Enterprise customers can configure custom retention policies.

Data Storage and Security

All telemetry data is stored in ClickHouse Cloud with encryption at rest. Data in transit is encrypted using TLS. Access to telemetry data is scoped by tenant identifier — each organization can only query its own data.

Self-Hosted Deployments

When using Skills Trace core library with self-hosted emitters (SQLite, PostgreSQL, JSONL), all data remains within your infrastructure. No telemetry is sent to Skills Trace servers unless you explicitly configure the HTTP emitter to do so.

Third-Party Services

The Skills Trace managed service uses ClickHouse Cloud for data storage and Vercel for application hosting. We do not share telemetry data with any other third parties.
