Gnosis Privacy Policy

Gnosis does not collect any personal data. Specifically:

• No personal identification information (name, email, etc.)
• No browsing history
• No click behavior or usage habits
• No cookies or any tracking technologies
• No data sharing with any third parties

The extension uses Chrome's chrome.storage.local API to store the following data locally in your browser:

• User settings: API URL, model name, API Key, theme preference, language preference
• Explanation cache: Previously queried terms and AI responses, to avoid redundant API calls (LRU, 7-day TTL, max 500 entries)
• Usage statistics: Lookup counts, cache hits, etc., displayed locally only
• Force-select site list: User-enabled domain whitelist for text selection

All the above data is stored only in your browser and is never uploaded to any server. Uninstalling the extension will remove all stored data.

When you select text and trigger a lookup, the extension sends the following to the AI API service you configured yourself:

• The selected term text
• The surrounding context paragraph (to provide contextual definition)

Gnosis does not operate any AI service. Your chosen API provider (e.g. OpenAI, Anthropic, DeepSeek, OpenRouter, or a local model via Ollama) is governed by its own privacy policy. Please review that provider's policy to understand how they handle data.

The extension requests the following browser permissions, each with a specific purpose:

Permission	Purpose
storage	Store user settings and explanation cache locally
activeTab	Read the selected text and surrounding context on the current page when the user triggers a lookup
scripting	Inject CSS to lift text-selection restrictions on sites that block selection, when the user explicitly enables it
contextMenus	Add a "Define with Gnosis" right-click menu entry on selected text
host_permissions: <all_urls>	Detect text selection and show explanation tooltip on any webpage

Gnosis is not directed at children under 13 and does not knowingly collect personal information from children.

We may update this privacy policy from time to time. Significant changes will be communicated through Chrome Web Store extension update notes. Continued use of the extension constitutes acceptance of the revised policy.
