Privacy Policy for ARSIM Copilot

ARSIM Copilot ("we", "our", or "the Extension") is an open-source educational companion built for aviation students practicing radio communications on the ARSim platform (arsim.ai). We are committed to absolute user privacy and zero data collection.

1. Information We Do Not Collect

ARSIM Copilot does not collect, record, log, sell, or transmit any category of user data, including but not limited to:

• Personally Identifiable Information (PII): No names, email addresses, phone numbers, physical locations, or device identifiers.
• Authentication & Credentials: No ARSim passwords, session cookies, auth tokens, or payment details.
• Microphone & Audio Data: All speech synthesis and audio generation are computed locally via WebAssembly within your browser. Audio streams are played into the browser session and are never recorded to external servers.
• Browsing History & User Activity: We do not track websites visited, keystrokes, mouse position, or analytics. The extension only executes on explicit user request on arsim.ai.

2. Chrome Permissions & Technical Justification

To adhere to the principle of least privilege, ARSIM Copilot requests only the minimum necessary permissions in its Manifest:

• offscreen: Required by Google Chrome Manifest V3 to execute the in-browser WebAudio WebAssembly speech synthesis engine (sanoTTS) in an isolated offscreen document without blocking the user interface.
• content_scripts (https://arsim.ai/*): Scoped strictly to the ARSim training domain to render the floating frosted glass training overlay and deliver simulated push-to-talk readbacks during practice exercises.

The extension contains zero remote code (no external scripts, no eval, no external CDN dependencies).

3. Third-Party Services & Disclosures

ARSIM Copilot does not integrate with any third-party advertising, analytics, or tracking platforms. No data is shared with or sold to third parties under any circumstances.

4. Chrome Web Store Compliance

In accordance with Google Chrome Web Store Developer Program Policies:

• ARSIM Copilot has a single, narrow, easy-to-understand purpose: assisting pilots with aviation radio telephony practice on ARSim.
• The extension does not use user data for lending, creditworthiness, advertising, or unrelated purposes.
• Source code is fully auditable and open-source.
