Privacy Policy

Last updated: February 2026

1. Introduction

Gantt Zero ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how our web application collects, uses, and safeguards your information when you connect and use the Gantt Zero service. Our core philosophy is that your data belongs to you. We do not store your plans, tasks, or Google Drive files on our servers.

Google API Services Usage Disclosure

Gantt Zero's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

2. Information We Access via Google Drive

Gantt Zero integrates with Google Drive to allow you to save your project plans seamlessly. To do this, we request the https://www.googleapis.com/auth/drive.file scope.

  • We ONLY read and modify files created specifically by the Gantt Zero application.
  • We cannot and do not access, read, or modify any other personal files, folders, or documents stored on your Google Drive.
  • Your authentication token is stored locally in your browser to maintain your active session and is never transmitted to any central database owned by us.

3. Data Storage & Sharing

Because Gantt Zero operates entirely within your web browser (client-side), your project data goes strictly between your local computer and your Google Drive account. We do not possess a central database that stores your personal information, tasks, project names, or team member assignments.

We do not sell, rent, or share your Data with any third parties, advertisers, or affiliated organizations.

4. Revoking Access

You have total control over your data. You may revoke Gantt Zero's access to your Google Drive at any time. Simply visit your Google Account settings (myaccount.google.com/permissions), locate Gantt Zero in the list of third-party apps, and click "Remove Access".
