PRIVACY_POLICY

Last updated: January 2026

SUMMARY

Your Claude Code session data stays on your machine
We collect anonymous usage telemetry (command names + timing only)
No file paths, session content, or personal data is collected
You can opt out of telemetry at any time

1. DATA_THAT_STAYS_LOCAL

Tastematter processes your Claude Code session files to build a local database. This data never leaves your computer:

Session JSONL files from Claude Code
Parsed conversation content
File paths you worked on
Tool usage details
Your local SQLite database

2. TELEMETRY_WE_COLLECT

To improve Tastematter, we collect anonymous usage data. Here's exactly what we collect:

# Example telemetry event
{
  "event": "query_executed",
  "anonymous_id": "uuid-generated-on-first-run",
  "properties": {
    "command": "query flex",
    "time_range": "7d",
    "result_count": 42,
    "duration_ms": 156
  }
}

What we collect:

Command names (e.g., "query flex", "daemon start")
Timing information (duration, time ranges)
Aggregate counts (number of results, sessions parsed)
Platform (Windows, macOS, Linux)
Anonymous installation ID (random UUID)

What we NEVER collect:

File paths or directory names
Session content or conversations
Your name, email, or any personal information
Query results or actual data
IP addresses (anonymized by our analytics provider)

3. HOW_TO_OPT_OUT

You can disable telemetry at any time using either method:

# Option 1: Environment variable
export TASTEMATTER_NO_TELEMETRY=1

# Option 2: Config file (~/.context-os/telemetry.yaml)
telemetry:
  enabled: false

4. ANALYTICS_PROVIDER

We use PostHog for analytics. PostHog is privacy-focused and compliant with GDPR and CCPA. See their privacy policy.

5. DATA_RETENTION

Anonymous telemetry data is retained for 12 months to analyze usage trends, then automatically deleted.

6. CHANGES

We'll update this policy if our data practices change. Check back periodically.
