This is the privacy policy for **ThumbSnap** — Download YouTube thumbnails in one click. The extension page is at https://www.extensionshop.store/extension/thumbsnap.

## Data collected

| Data | Optional | Purpose |
| --- | --- | --- |
| Active tab URL (YouTube only) | No | The URL of the currently active YouTube tab is read locally to extract the video ID. It is never stored, transmitted, or logged — used only in-memory to construct the thumbnail download URL. |
| Active tab title (YouTube only) | No | The page title of the current YouTube tab is read locally to generate a human-readable filename for the downloaded image. It is never stored or transmitted. |

## Never collected

- Browsing history or activity outside the active YouTube tab
- Personal information, accounts, emails, or identifiers
- Analytics, telemetry, or usage tracking of any kind
- Cookies, localStorage, or any persistent storage
- Page content, DOM elements, or video data
- Data sent to any first-party or third-party server

## Third-party sharing

ThumbSnap does not send any data to any server. The only network requests are to YouTube's public thumbnail CDN (i.ytimg.com) to check image availability and download images. No personal data, browsing data, or usage data is ever transmitted anywhere.

## Encryption

No data is transmitted.

## Data retention

ThumbSnap does not store any data. No cookies, no localStorage, no chrome.storage. The tab URL and title are read into memory, used to download the thumbnail, and immediately discarded. Downloaded images are saved to your device via Chrome's downloads API and managed entirely by your browser.

## Permissions

| Permission | Why it is needed |
| --- | --- |
| Active Tab | Reads the current tab's URL to extract the YouTube video ID, and the tab title to generate a descriptive filename for the downloaded thumbnail. |
| Context Menus | Adds a "Download Thumbnail" right-click option when you right-click on YouTube thumbnail images. |
| Downloads | Saves thumbnail images to your device using Chrome's built-in downloads API. |
| Host Access (youtube.com) | Allows the extension to detect YouTube video pages and inject download overlay buttons on the page. |
| Host Access (i.ytimg.com) | Fetches thumbnail images from YouTube's public image CDN. HEAD requests check availability; GET requests download the image. |
