Homeboard Privacy Policy

Homeboard is a Chrome new tab extension that provides bookmark management, todos, quick links, a Prompt Library, Pan Search, and optional local MCP Companion features. This policy explains what data Homeboard handles, how that data is used, and what controls you have.

1. What Data We Handle

• Bookmark data: when you use the bookmark tree, drag and drop, rename, create, delete, or sync features, the extension reads and updates Chrome bookmarks.
• Local content data: todos, quick links, settings, Prompt Library items, and MCP server configurations are stored locally in the browser.
• Pan Search query data: when you actively use Pan Search, the search keyword is sent to the third-party service www.quarkpanso.com to return results.
• Local installation state: if you actively use the local MCP Companion installation flow, the extension stores a small amount of local state such as installation intent timestamps.
• Optional local bridge data: only if you actively grant the nativeMessaging permission and install the local Companion, prompt snapshots and server metadata are sent to software running on your own machine.

2. How Data Is Stored

• The extension primarily uses chrome.storage.local to store settings, todos, quick links, Prompt Library content, and MCP server configuration.
• In local preview mode where extension APIs are unavailable, the page may fall back to browser localStorage.
• Pan Search stores a locally generated random client fingerprint and a cached Quark signer module URL to support request signing and compatibility.
• Homeboard also creates an internal bookmark cache folder named .__HOMEBOARD_SYNC_CACHE__ DO NOT DELETE (bookmark cache) to keep bookmark-backed copies of todo and quick link data.

3. Where Data May Be Sent

• Homeboard does not operate a developer-hosted cloud backend and does not upload your data to developer-controlled servers.
• When you use Pan Search, the query and required request fields are sent to www.quarkpanso.com.
• When you open DeepSeek or OpenAI panels inside Homeboard, those pages load from chat.deepseek.com, chatgpt.com, chat.openai.com, or auth.openai.com. Login state, conversations, and further processing on those pages are governed by the privacy policies of those third-party services.
• UI font resources may load from Google Fonts related domains, so the browser may make standard resource requests to those domains.
• If you have Chrome bookmark sync enabled, internal bookmark cache entries created by Homeboard may also be synchronized by Chrome as part of Chrome's own sync behavior.
• If you actively install and enable the local MCP Companion, the extension sends prompt snapshots and server metadata to software running locally on your device, not to a developer server.

4. Why the Data Is Used

• To display, edit, and organize your bookmarks.
• To save your todos, quick links, prompts, and extension settings.
• To keep Homeboard data consistent between bookmarks and local state.
• To perform Pan Search queries that you explicitly initiate.
• To provide configuration and prompt snapshots to the local MCP Companion when you explicitly enable it.

5. What We Do Not Do

• We do not sell your personal data.
• We do not use your data for ad targeting.
• We do not upload your bookmarks, todos, quick links, or prompt content to a developer-hosted server without a user-initiated action that requires third-party communication.
• We do not collect separate analytics trackers, advertising identifiers, or data broker information.

6. Your Choices and Controls

• You can edit or delete todos, quick links, Prompt Library items, and bookmark changes created through the extension.
• You can delete the Homeboard bookmark cache folder and related entries in Chrome.
• You can remove the extension in Chrome, which also removes extension local storage.
• You can choose not to grant the optional nativeMessaging permission, or revoke it later.
• If you installed the local MCP Companion, you can uninstall that local program separately.

7. Third-Party Services

Homeboard may interact with third-party services such as Quark Pan Search, OpenAI, DeepSeek, Google Fonts, and any sites you explicitly open through quick links. Those services have their own terms and privacy policies and are outside Homeboard's control.

8. Policy Updates

If Homeboard's data handling changes, this page will be updated and the effective date will be revised. Please review this policy when using a new release.

9. Contact

To contact the developer, use the contact details shown on the Chrome Web Store listing or any public contact channel provided on the published project page.
