Privacy Policy

Last updated: May 2026

Overview

ListDiff does not collect, transmit, or store any personal data or the text you enter into its tools. All processing happens entirely within your browser. Nothing you type is ever sent to a server.

Data We Collect

We do not collect names, email addresses, IP addresses, or any other personal information directly. We have no user accounts, no login, and no analytics that identify individual users.

Browser Storage

Your tool settings (such as selected delimiter, sort order, and other options) are saved in your browser's localStorage. This data stays on your device and is never transmitted anywhere. You can clear it at any time by clearing your browser's site data.

Advertising

ListDiff displays ads served by Ezoic, an ad network and technology platform. Ezoic and its advertising partners may use cookies and similar technologies to:

  • Display personalised or contextual ads
  • Measure ad performance
  • Prevent ad fraud

Ezoic's use of advertising cookies is governed by their own privacy policy. You can manage your ad preferences via the consent banner shown on your first visit, or by visiting Ezoic's privacy portal for this site.

Third-Party Services

ListDiff is hosted on Cloudflare Pages. Cloudflare may log basic request metadata (IP address, user-agent, URL) for security, abuse prevention, and performance purposes. This is governed by Cloudflare's privacy policy.

Your Rights

Since we don't collect personal data, there is nothing for us to provide, correct, or delete on your behalf. If you have questions about data collected by Ezoic or Cloudflare, please contact those services directly.
