Privacy Policy

1. No Personal Data Collection

ASINSnap does not collect, store, or transmit any personal data. There is no account system, no login, and no registration of any kind. You install the extension and use it immediately. The only data that leaves your browser is the anonymous usage statistics described in Section 5 — these contain no personal information and cannot be linked to you.

2. How the Extension Works (Local Processing)

All processing happens entirely within your browser:

• Product images are fetched directly from Amazon's servers to your browser, then packaged into a ZIP file using JavaScript running locally.
• Product videos (HLS streams) are detected and converted to MP4 using FFmpeg.wasm — a WebAssembly build of FFmpeg that runs entirely in your browser. No video data passes through any third-party server.
• We cannot see which products you browse or which files you download.

3. Local Browser Storage

The extension uses Chrome's session storage (chrome.storage.session) to temporarily cache the list of detected video URLs for the current browser session. This data:

• Never leaves your device.
• Contains only media URLs from the Amazon page you are viewing, not any personal information.
• Is automatically cleared when you close the browser.

4. Permissions Explained

ASINSnap requests only the minimum permissions necessary:

• Host permissions (amazon.* domains): To read product image and video data from the Amazon product page you are currently viewing. The extension only activates on pages with /dp/ in the URL.
• Storage: To cache detected video URLs temporarily within your current browser session (see Section 3).
• Downloads: To save ZIP files and MP4 videos to your computer.
• webRequest: To detect HLS video stream URLs as they are loaded by the Amazon page, so they can be listed in the extension panel.
• offscreen: Required by Chrome to run FFmpeg.wasm for video conversion in a background context.
• sidePanel: To display the extension interface as a side panel instead of a popup.

We do not request access to <all_urls>, browsing history, cookies, or any data outside of Amazon product pages.

5. Anonymous Usage Statistics

To understand which features are used and catch failures (for example, how often a download fails), the extension reports a small set of anonymous usage events. Each event contains only:

• The event name (e.g., download_success, preview_error) and basic counts (number of images, number of variants).
• The Amazon marketplace domain (e.g., amazon.com vs amazon.de) — never the product, URL, or page content.
• Your browser's interface language and the extension version.
• A randomly generated identifier stored locally in your browser. It is created by a random-number generator, is not derived from your device or identity, and is used only to count unique installs.

We never collect your name, email, IP-based location profiles, browsing history, search queries, or the products you view. These statistics are transmitted using the Google Analytics Measurement Protocol (a plain network request — the extension contains no third-party analytics scripts, SDKs, or tracking pixels) and are used solely to improve the extension. They are never sold or shared for advertising.

6. This Website (asinsnap.com)

This website is separate from the browser extension. If you sign up for early access notifications on this website, your email address is stored by our email service provider solely to send you a one-time notification. You can unsubscribe at any time by clicking the link in the email.

This website may use standard server logs (IP address, browser type, page visited) for security and performance monitoring. These logs are not shared with third parties and are not used for advertising.

We use Microsoft Clarity on this website to understand how visitors interact with our pages through behavioral metrics, heatmaps, and session replay. Clarity masks sensitive content (such as text you type) by default. The data collected is used to improve this website and is processed by Microsoft as described in the Microsoft Privacy Statement. Clarity runs only on this website — it is never included in the browser extension.

We also use Google Analytics 4 on this website to measure anonymous, aggregate traffic such as page views, traffic sources, and clicks that lead to the Chrome Web Store. This helps us understand which pages are useful and improve the website. Google Analytics runs only on this website and is never included in the browser extension. Learn more in the Google Privacy Policy.

7. Children's Privacy

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

8. Changes to This Policy

If we make material changes to this policy — for example, when we add features that involve data processing — we will update the date at the top of this page and, where appropriate, notify users through the extension.
