Privacy Policy

This Privacy Policy describes how GrowIndex ("we," "our," or "us") collects, uses, and protects information when you use our website and tools. By using GrowIndex, you agree to the practices described in this policy.

1. Information We Collect

GrowIndex is a static website. Our tools perform all calculations locally in your browser; we do not transmit your calculator inputs to any server.

We may collect limited anonymous usage data through analytics services, including:

• Pages visited and time spent on each page
• Browser type, operating system, and screen resolution
• Referring website or search query
• General geographic region (country-level)

We do not collect names, email addresses, or any personally identifiable information unless you voluntarily provide it through a contact form.

2. Cookies and Local Storage

GrowIndex uses a single cookie consent mechanism stored in your browser's local storage under the key "ck." This is used solely to remember your cookie consent preference and expires with your browser session or when you clear local storage.

We may use analytics cookies from third-party providers (such as Google Analytics) to understand aggregate usage patterns. These cookies do not identify you personally. You can opt out of analytics cookies by declining the cookie consent banner or using browser privacy settings.

3. How We Use Data

Anonymous usage data is used exclusively to:

• Understand which tools and articles are most useful
• Identify and fix technical issues
• Improve navigation and content organisation
• Monitor site performance and uptime

We do not sell, rent, or share any data with third parties for marketing purposes.

4. Third-Party Services

GrowIndex uses the following third-party services that may set cookies or collect data according to their own privacy policies:

• Google Fonts: Delivers typeface files. Google may log requests. See Google's Privacy Policy for details.
