Overview

ZeroData Tools (zerodatatools.com) is a collection of browser-based developer utilities. The core tools process your input locally in the browser, while the website itself uses third-party analytics, advertising, and infrastructure services described below.

Local Processing Guarantee

We do not collect, store, transmit, or process any user input on our servers. All formatting, validation, encoding, decoding, and conversion operations happen entirely within your web browser using client-side JavaScript. When you paste JSON, text, or tokens into ZeroData Tools, your payload never leaves your local machine. This zero-data-transmission architecture inherently protects you from server-side data breaches and unauthorized logging. You can verify this by inspecting your browser's network activity during tool usage.

Cookies & Tracking Policy

While our core developer utilities execute entirely locally and require no cookies to function, the ZeroData Tools website utilizes cookies and local storage mechanisms to support site infrastructure, performance analytics, and advertising.

Third-party vendors, including Google, use cookies to serve advertisements based on your prior visits to this website or other websites across the internet. These cookies allow advertising partners to recognize your browser and deliver relevant content. We do not use cookies to track the data you input into any developer tool.

Analytics & Diagnostics

To understand traffic patterns and improve the user experience, we use Google Analytics and Microsoft Clarity. These services may collect technical and interaction data such as page views, approximate geography, device or browser details, and on-page interaction signals in accordance with their own policies.

GDPR, CCPA & Global Privacy Compliance

ZeroData Tools is designed with privacy-by-default principles that align with the General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), and other global privacy frameworks.

  • Right to Access & Deletion: Because we do not store user accounts or save tool inputs to a database, there is no user data to export or delete. Your data remains in your control at all times.
  • Opt-Out of Sale of Personal Information (CCPA): We do not sell your personal information. Advertising networks may collect pseudonymous diagnostic and tracking data via cookies. You can manage or opt-out of personalized advertising through your browser settings or via Google's Ad Settings.
  • Data Portability: All outputs generated by our tools can be copied directly to your clipboard or downloaded locally, ensuring you always have immediate access to your processed data.

Third-Party Services & Advertising

The site displays advertisements via Google AdSense to support ongoing development. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and/or other sites on the Internet.

Users may opt out of personalized advertising by visiting Google's Ads Settings. For more information on how these services operate, please review their respective privacy policies:
