InfoBlend is a browser extension that helps users understand web content via definitions, translations, summaries, and a Saved Vault.
Nothing. InfoBlend has no servers we operate, no analytics, no telemetry, and no user accounts. We never see your browsing history, the text you select, or the words you save.
- Definitions: the word or phrase you look up is sent to one or more of these public APIs: Dictionary API, Datamuse, Wiktionary, Wikipedia, and Urban Dictionary. These services log API requests per their own privacy policies; InfoBlend does not add identifiers.
- Translation: when no AI key is configured, selections are sent to MyMemory for translation, subject to their privacy policy.
- AI features (optional): if you configure an AI key in the popup, your selections and questions are sent directly from your browser to the endpoint you specified — Google's Generative Language API, OpenAI's Chat Completions API, or a custom endpoint of your choosing. InfoBlend is not a relay or middleman.
- No third-party advertising, fingerprinting, or analytics SDKs.
- Your settings (theme, accent color, target language, etc.) in
chrome.storage.sync, which Chrome replicates across your signed-in browsers. - Your Saved Vault, definition cache, and AI key in
chrome.storage.local, which stays on the device. Your AI key is encrypted at rest with AES-GCM (PBKDF2-derived key, 600k iterations).
You can list hostnames in the popup to silence InfoBlend on those sites entirely — no scripts run, no requests are made.
The Saved Vault includes a one-click CSV and Markdown export. Removing the extension deletes everything stored locally.
