Privacy Policy

Last updated: 2026-03-30

rubber-duck is a Claude Code plugin. This policy explains what data is collected, where it stays, and what we do with it.

What we collect

rubber-duck collects the following data locally on your machine:

• A one-way hash of your project path (8 characters, used for streak tracking — not reversible to the original path)
• Whether you used /duck:reveal in a session
• Session duration in minutes
• A timestamp for each session

Where data is stored

All data is stored exclusively on your local machine at:

• ~/.rubber-duck/sessions/ — per-session log files
• ~/.rubber-duck/stats.json — running streak and totals

No data is transmitted to any server, third party, or external service. Ever.

What we do not collect

• Your code, file contents, or project structure
• Your conversation content with Claude
• Your name, email, or any identifying information
• Your actual project path (only an 8-character hash)
• IP addresses or usage analytics

Third-party services

rubber-duck has no backend, no analytics, and no third-party integrations. It runs entirely within Claude Code on your machine.

Deleting your data

To delete all locally stored data, remove the directory:

rm -rf ~/.rubber-duck

Changes to this policy

If this policy changes in a meaningful way, the updated version will be committed to the GitHub repository with a clear commit message.
