Privacy Policy

What Pax Does

Pax is a browser extension that analyzes the content of web pages you visit to detect manipulation patterns, influence tactics, and persuasion techniques. It also analyzes privacy policies and app store pages to surface key data practices in plain language.

Pax is operated by the developer as a personal cognitive tool. It is not affiliated with any news organization, political group, or advertiser.

What Data Pax Collects

Pax does not collect, store, or transmit personal data to any server controlled by Pax or its developer. Specifically:

• No browsing history is stored or transmitted
• No personal identifiers (name, email address, IP address) are collected
• No page content is stored after analysis is complete
• Your API key is stored locally in your browser using Chrome's built-in storage API and is never transmitted to us
• No analytics or usage tracking is performed

How the Anthropic API Is Used

When you trigger a page scan, Pax sends the visible text content of the current page directly to the Anthropic Claude API using your personal API key. This communication is between your browser and Anthropic's servers only.

Pax does not intercept, log, or store this data. Anthropic's privacy policy governs that interaction and can be found at anthropic.com/privacy.

Because you use your own API key, you are a direct customer of Anthropic — not an intermediary. Pax never sees or stores your API key beyond saving it locally in your browser.

What Is Stored Locally

Pax stores the following data locally on your device only, using chrome.storage.local:

• Your Anthropic API key
• Your extension settings (auto-scan preference, orb visibility, snooze status)
• The most recent scan result for the current tab — cleared when you close the tab

This data never leaves your device and is not accessible to Pax or any third party.

Permissions Explained

Pax requests the following browser permissions:

• activeTab — Used to read the content of the current page for manipulation detection
• storage — Used to save your API key and settings locally on your device
• scripting — Used to highlight detected patterns on the page
• host_permissions (<all_urls>) — Required to analyze content on any website you visit. Pax only activates when you trigger a scan — it does not monitor background tabs.

Third-Party Services

Pax uses one third-party service: the Anthropic Claude API. No other third-party services receive data from Pax. Pax does not use advertising networks, analytics platforms, or data brokers.

Children's Privacy

Pax is not directed at children under the age of 13 and does not knowingly collect information from children. If you believe a child has used this extension in a way that raises privacy concerns, please contact us.

Changes to This Policy

We may update this privacy policy from time to time. Updates will be posted at this URL. Continued use of the extension after updates constitutes acceptance of the revised policy. The "last updated" date at the top of this page will always reflect the most recent revision.
