Overview

ZeroData Tools (zerodatatools.com) is a collection of browser-based developer utilities. This privacy policy explains how the site handles your data — which is, in short: it does not collect any.

Data Collection

We do not collect, store, transmit, or process any user input. All formatting, validation, encoding, decoding, and conversion operations happen entirely within your web browser using client-side JavaScript. No data you type or paste into any tool is sent to any server.

Cookies

ZeroData Tools does not use cookies for tracking purposes. The site may store a theme preference (light/dark mode) in your browser's local storage. This data stays on your device and is never transmitted.

Analytics

The site may use privacy-respecting analytics services to understand aggregate traffic patterns (e.g., page views, country-level geography). No personally identifiable information is collected.

Third-Party Services

The site loads fonts from Google Fonts and may display ads via Google AdSense. These services operate under their own privacy policies:

Children's Privacy

ZeroData Tools does not knowingly collect any information from children under the age of 13.

Changes to This Policy

This policy may be updated periodically. The "last updated" date at the top of this page reflects the most recent revision.
