Privacy Policy

Last Updated: August 24, 2026

Our privacy policy can be summarized in one sentence:
Your files never leave your device.

1. Local Processing (No File Uploads)

Unlike traditional cloud-based tools, Cluster Tools processes all files entirely within your web browser using client-side technologies (such as WebAssembly and Web Workers). When you use our tools to convert, compress, resize, or edit a file, that file is never uploaded to our servers. It is read locally by your browser, processed locally, and saved locally. We have no technical capability to view, store, or share the files you process.

2. Analytics and Tracking

To understand how our tools are used and to improve the service, we use privacy-friendly, anonymized analytics (such as Vercel Web Analytics). This collects basic, non-personally identifiable information such as:

• Page views and navigation paths
• General geographic region (country level)
• Browser and device type

This analytics data contains no information about the files you process or your specific identity.

3. Cookies

Cluster Tools does not use tracking cookies or advertising cookies. Any local storage used by the site is strictly functional (for example, temporarily holding a file in memory while it is being processed by a tool in your active session).

4. Third-Party Links

Our website may contain links to external sites that are not operated by us. Please be aware that we have no control over the content and policies of those sites, and cannot accept responsibility or liability for their respective privacy practices.
