Privacy Policy

01What LocalMind is

LocalMind is a Chrome extension that provides an AI assistant powered by Gemini Nano, the AI model built into Google Chrome, which runs on your own device.

02Data the extension handles and why

• Conversations and drafts: the messages you write and the assistant's answers are stored in Chrome's local storage (chrome.storage.local) to show your history.
• Web page content: only when you ask for it (the "Use the current page" button, right-click menu, keyboard shortcut or floating widget), LocalMind reads the text of the page or your selection to pass it to the local model.
• Files you attach (PDF, Word, Excel, PowerPoint, text, images): they are read in your browser to answer your request. Images are not stored.
• User space passwords: used only momentarily to derive an encryption key (PBKDF2). The password is never stored.
• Preferences: language, theme, work mode and whether the widget is enabled.

All of this data is processed and stored exclusively on your device. LocalMind does not transmit any data to its developers or to third parties.

03AI processing

Requests are processed with Chrome's Prompt API on Gemini Nano, which runs locally. On first use, Chrome downloads the model from Google; that download is handled by the browser under Google's terms and does not include your conversations.

04Encryption and user spaces

If you create a protected space, your conversations, drafts and history are encrypted on the device with AES-256-GCM. The key is only unlocked with your password and stays in memory until you lock the space or close the browser. If you forget the password, the data cannot be recovered.

05Permissions

• storage and unlimitedStorage: store your history and settings locally.
• activeTab and scripting: read the text of the active page when you ask for it.
• contextMenus: right-click actions (summarize, translate, proofread…).
• sidePanel: open LocalMind in the side panel.
• Optional website access (<all_urls>): requested only if you enable the floating widget or use LocalMind from the side panel or a tab, to read the page you choose. You can revoke it at any time from chrome://extensions.

06Sharing and sale of data

We do not sell, rent or share user data. It is not used for advertising, to determine creditworthiness or for any purpose unrelated to the extension's function. The use of data complies with the Chrome Web Store User Data Policy, including the Limited Use requirements.

07Retention and deletion

Data stays on your device until you delete it. You can delete individual conversations, use Settings → Data deletion to delete all conversations in a space or the whole space, or uninstall the extension, which removes all of its local data.

08Children

LocalMind is not directed at children under 13 and does not collect data from any user.

09Changes

If this policy changes, we will update this page and its date.
