Privacy Policy for DeceptionProbe

Last updated: October 2026

Privacy-First Commitment: DeceptionProbe does NOT collect, transmit, sell, or store any personal user data, prompts, or chat histories on external servers. All linguistic and mechanistic honesty auditing occurs 100% locally on your device within your browser session.

1. Data Collection & Processing

DeceptionProbe operates strictly as an in-browser client tool. When active on supported AI interfaces (ChatGPT, Claude, Gemini, Perplexity), the extension inspects DOM text elements locally to calculate sycophancy and honesty scores. No prompt text or AI responses are ever logged or sent to any remote server.

2. Permissions Justification

storage: Used exclusively to save your local UI preferences (e.g. enabling/disabling in-line highlighting and strict mode) on your local device.
activeTab / Host Permissions: Required to allow the content script to display the honesty HUD overlay on supported conversational AI domains (chatgpt.com, claude.ai, gemini.google.com, perplexity.ai).

3. Third-Party Sharing

We do not share, sell, or transfer any data to third parties. We do not use third-party tracking scripts, analytics, or advertising libraries.

4. Open Source Transparency

The complete source code for DeceptionProbe is publicly available and open-source under the MIT license at:
