Privacy Policy

This page explains what happens to data when you use ImageDup. It describes the site as it is actually built. It is not legal advice.

Your CSV file

When you choose or drop a CSV file, it is read by JavaScript running in your browser and analyzed on your device. The file is not sent to an ImageDup application server, because there is no ImageDup application server — the site is static and has no backend that could receive it.

Nothing from your file is transmitted, stored, or logged by ImageDup. The results table and the downloadable results CSV are generated in your browser. When you close or reload the page, that data is gone; the tool does not use cookies, localStorage, or any other persistent browser storage.

The "Use sample data" button fetches a small example file (/sample-products.csv) that is bundled with the site. That is a normal request for a static file on this domain and does not involve any file of yours.

Hosting and server logs

The site is served as static files by a third-party hosting/CDN provider. Like almost any website, the provider's infrastructure may automatically record standard request metadata — for example your IP address, user-agent string, the URL requested, and a timestamp — in access logs used for security and to operate the service. These logs are handled by the hosting provider under its own terms; ImageDup does not add its own server-side logging on top of them and does not combine these logs with anything from your CSV file.

Analytics

This site uses one analytics tool, Google Analytics (GA4). Google's tag (gtag.js) loads on every page and is not gated behind any cookie-consent step. Beyond Google Analytics, this site does not run tracking pixels, session recording, fingerprinting, advertising scripts, or any other embedded third-party widget.

Google Analytics sets first-party cookies in your browser to distinguish visitors between visits, and it collects standard usage data such as which pages you view. On the page-not-found page specifically, the path you requested (not the full URL, and not any query string) is also sent to Google Analytics as an event, so broken links can be found and fixed. Google processes this data under its own privacy policy at policies.google.com/privacy.

This section describes what the site's code actually does. It is not a claim that this use of Google Analytics complies with the GDPR, CCPA, or any other law.

Cookies

Google Analytics sets first-party cookies, as described above. Outside of Google Analytics, ImageDup does not set its own cookies, and the CSV tool itself still uses no cookies or localStorage (see "Your CSV file" above).

What this means in short

  • Your CSV data stays on your device and is never sent to ImageDup or to Google Analytics.
  • Google Analytics is used site-wide and sets cookies; see "Analytics" above for what it collects.
  • Beyond Google Analytics, ImageDup itself collects and stores nothing about you.
  • Your hosting provider's normal access logs are a separate exception, outside ImageDup's control.

Children

ImageDup is a tool for people who maintain product catalogs and is not directed at children.

Changes

If the site changes in a way that affects this policy, this page will be updated before that change goes live.
