Privacy Policy
Last Updated: December 12, 2025
Introduction
Prompt Critic ("we," "our," or "the app") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our macOS application.
Information We Collect
Prompt Content
When you use Prompt Critic to analyze your prompts, the content you write is sent to Claude AI (Anthropic) for analysis. This is necessary to provide real-time feedback and suggestions.
Local Files
All .prompt files you create or edit are stored locally on your Mac. We do not have access to these files unless you explicitly send their content for analysis.
API Keys
Your Claude AI API key is stored securely in your macOS Keychain and is never transmitted to us. It is only used to communicate directly with Anthropic's API.
How We Use Information
The prompt content you send for analysis is used solely to:
- Generate real-time feedback and suggestions
- Identify areas for improvement in your prompts
- Provide priority-based recommendations
We do not store, log, or retain your prompt content on our servers. All processing is done through direct communication with Anthropic's API.
