Privacy Policy

Last updated: October 28, 2026

The short version

Whatever you type, paste or open in a ZTool tool is processed by JavaScript inside your own browser. It is never sent to our servers, and we have no way to see it.

Information we do not collect

• The contents of any text, file, image or number you use with our tools.
• Account details. There are no accounts.
• Tracking cookies for advertising profiles.

Information our host may log

Like any website, our hosting provider may keep standard server logs, such as IP address, browser type and the page requested. These logs are used only for security and to keep the service running, and they are deleted on a rolling basis.

Local storage

Some tools may save small preferences, such as your last selected unit, in your browser's local storage. That data never leaves your device, and you can clear it at any time in your browser settings.
