Privacy Policy

Effective Date: February 23, 2026

LLMural is a Chrome extension that customizes the visual appearance of Claude (claude.ai), ChatGPT (chatgpt.com), and Google Gemini (gemini.google.com). This policy explains what information LLMural does and does not collect.

1. What We Do Not Collect

LLMural is designed with privacy as a core principle. The extension does not, under any circumstances:

  • Read, access, store, or transmit any content from your AI conversations — including prompts, responses, or any other messages displayed on the page.
  • Collect any personally identifiable information such as your name, email address, or IP address.
  • Track your browsing history or activity on any website.
  • Send any data to external servers or third parties.
  • Use analytics, tracking pixels, or any other monitoring tools.

2. What We Do Store

LLMural stores only the visual customization settings you configure — such as your chosen background color, font family, and font size. These settings are stored exclusively using Chrome's built-in storage API (chrome.storage.sync), which syncs your preferences across your own Chrome browsers if you are signed into Chrome. This data:

  • Consists only of your chosen display preferences (colors, fonts, sizes).
  • Never leaves your browser except through Chrome's own sync mechanism, which is controlled entirely by Google.
  • Is never accessed by LLMural's developer or any third party.
  • Can be deleted at any time by uninstalling the extension or clearing Chrome extension storage.

3. Permissions

LLMural requests the following Chrome permissions, which are the minimum required to function:

  • activeTab / tabs: Required to detect which AI site you are visiting so the correct default settings can be applied. LLMural reads only the URL of the active tab — nothing else.
  • storage: Required to save and sync your visual preferences across browser sessions.
  • Host permissions (claude.ai, chatgpt.com, gemini.google.com): Required to inject the CSS that applies your visual customizations. LLMural does not read page content — it only writes visual styles.

4. Third-Party Services

LLMural Pro (paid tier) uses LemonSqueezy to process payments. LemonSqueezy's privacy policy governs any data collected during the purchase process. LLMural does not receive or store your payment information. License key validation involves a minimal server call that checks whether a provided key is valid — no personal data is transmitted in this call.

5. Children's Privacy

LLMural does not knowingly collect any information from children under the age of 13. The extension collects no personal data from any user regardless of age.

6. Changes to This Policy

If this Privacy Policy changes materially, the updated version will be posted at llmural.com/privacy with an updated effective date. Continued use of LLMural after such changes constitutes acceptance of the updated policy.
