Privacy Policy – YouTube Summarizer (Gemini)

Last updated: February 25, 2026

Overview

YouTube Summarizer (Gemini) is a Chrome extension that generates AI-powered summaries of YouTube videos using the Google Gemini API. This policy explains how the extension handles your data.

Data We Do Not Collect

This extension does not collect, store, or transmit any personally identifiable information. No analytics, tracking, or telemetry of any kind is used.

API Key Storage

Your Google Gemini API key is stored locally in your browser using Chrome's built-in chrome.storage API. It is never sent to the extension developer or any third party. It is used solely to make requests directly from your browser to Google's Gemini API.

Third-Party Services

The extension communicates only with:

• Google Gemini API (generativelanguage.googleapis.com) — to generate video summaries
• YouTube — to retrieve video transcript/metadata based on the URL you provide

These services are governed by their own privacy policies. The extension developer has no access to data exchanged between your browser and these services.
