Your data never leaves your computer.

Anti Hallucinations is a fully local fact-checking tool. It sends your text only to Ollama running on your own machine at localhost:11434. There are no external servers, no analytics, no accounts, and no internet requests of any kind beyond that local connection.

1. Overview

This Privacy Policy describes how the Anti Hallucinations Chrome extension handles information. The extension's sole purpose is to verify factual statements using AI models that run entirely on your local machine through Ollama.

By using the extension, you acknowledge this policy.

2. Data We Collect

We do not collect any data. Specifically:

We do NOT collect: the text you enter for verification, your browsing history, your IP address, device identifiers, usage statistics, crash reports, or any personally identifiable information of any kind.

The only information stored is your UI preferences (selected model and color theme), saved locally in your browser via chrome.storage.local. This data never leaves your device.

3. How the Extension Works

When you click Verify Fact, the extension:

1. Takes the text you typed
2. Sends it to http://localhost:11434 — your local Ollama instance
3. Receives a JSON response from Ollama
4. Displays the verdict (TRUE / FALSE / UNCERTAIN) in the popup

All of this happens entirely within your computer. The statement you enter never travels over the internet.

4. Permissions Used

The extension requests only the minimum permissions necessary to function:

Permission Purpose Sends data externally?
storage Saves your preferred model and UI theme locally in the browser No
host_permissions:
localhost:11434
Connects to Ollama running on your own machine to run the AI model No — localhost only
host_permissions:
127.0.0.1:11434
Alternative loopback address for the same local Ollama connection No — localhost only

No other permissions are requested now or in the future without an update to this policy.

5. Third-Party Services

This extension does not integrate with, communicate with, or share data with any third-party service, analytics platform, advertising network, or cloud AI provider.

The AI models you use are provided by Ollama, which you install and run locally. Ollama's own privacy practices apply to that software; this extension has no control over or relationship with Ollama's terms.

6. Children's Privacy

This extension does not target or knowingly collect any information from children under 13. Because we collect no personal data from anyone, this policy applies equally regardless of age.

7. Changes to This Policy

If this policy changes, the updated version will be published with a new effective date. Continued use of the extension after changes constitutes acceptance of the updated policy. Because we collect no data, changes will only ever relate to clarifications or new features that maintain the same privacy-first approach.

8. Contact

For questions about this policy or the extension, open an issue in the project's repository or reach out through the Chrome Web Store listing page.
