Data Collection
This extension does not collect, store, or transmit any personal data, browsing history, or page content to any server operated by the extension developer.
Local Storage
All data is stored locally on your device using `chrome.storage.local`:
- Extension settings (API endpoint, model, theme preferences, etc.) — stored as plaintext
- API key — encrypted via AES-GCM (Web Crypto API) before being stored locally
- Extracted page content & mindmap diagrams — stored only in memory during the current session; saved diagrams can be written as local JSON files you choose where to save, or saved as named records in browser storage (`chrome.storage.local`)
- Usage & lifecycle logs — stored locally for debugging
No data is ever sent to a server owned or operated by this extension's developer.
Third-Party LLM API
The extension sends extracted web page content to the AI API endpoint you configure (e.g., OpenAI, Anthropic, or any compatible provider) to generate mindmaps. You provide and control your own API key.
- The extension sends: the text content of the page you choose to summarize
- The extension does not send: your identity, browsing history, or any data from other sites
- The content shown in the "Source" tab is what gets sent — review it before generating to ensure no unintended information is included
Please review the privacy policy of your chosen LLM provider to understand how they handle data you submit through their API.
Data Sharing
We do not sell, rent, or share any user data with third parties.
