Privacy Policy

Z Test Calculator (https://ztestcalculator.com) respects your privacy. This Privacy Policy explains what information may be collected when you visit our website, how that information may be used, and the choices available to you.

This policy applies to our online calculators, statistical tools, educational articles, blog posts, and other services available through our website.

1. Information We Collect

The information we collect depends on how you use our website.

2. Calculator Inputs and Results

Z Test Calculator provides tools for statistical and mathematical calculations. The information you enter into a calculator may be processed to generate a result.

Where a calculator performs calculations directly in your browser, the entered values may be processed locally without being sent to our servers. However, this depends on how the specific calculator is implemented.

Please avoid entering personal, confidential, or sensitive information into our calculators unless it is necessary and you understand how that information is handled.

3. How We Use Information

We may use collected information for the following purposes:

• To operate and maintain our website.
• To provide calculators and display calculation results.
• To respond to messages and enquiries.
• To understand how visitors use our website.
• To improve website performance, usability, and content.
• To identify technical errors and help prevent abuse.
• To monitor website security and protect our services.
• To display and measure advertisements where advertising services are enabled.
• To comply with applicable legal requirements.

We aim to use information only for appropriate purposes related to operating, improving, and protecting our website.

4. Cookies and Similar Technologies

Our website and certain third-party services may use cookies, pixels, local storage, or similar technologies.

These technologies may help websites remember preferences, maintain functionality, understand visitor activity, measure advertising performance, and deliver relevant advertisements.

The cookies and technologies used depend on the features and services enabled on our website.

You can manage or block cookies through your browser settings. However, disabling certain cookies may affect some website features.

Where required by applicable law, we will seek consent before using technologies that require it.

5. Google AdSense and Advertising Partners

We may use Google AdSense or other third-party advertising services to display advertisements on our website.

These providers may use cookies or similar technologies to collect information about visits to this and other websites. This information may be used to display personalised or non-personalised advertisements, measure advertising performance, prevent fraud, and support advertising services.

The information processed may include IP addresses, browser details, device information, advertising identifiers, and interactions with advertisements, depending on the provider and applicable settings.

Google's use of advertising data is subject to its own policies and applicable privacy requirements.

Where applicable, you can manage advertising personalisation through your Google account settings. Advertising choices may also be available through our consent management tools, depending on your location and the services enabled.

6. Analytics and Website Performance

We may use analytics or website performance services to understand how visitors interact with our website.

These services may collect information such as pages viewed, visit duration, device type, browser information, approximate location, and interactions with website features.

We use this information to identify popular content, understand visitor needs, find technical problems, and improve the website.

The exact information collected depends on the analytics services installed on our website. We will update this policy if our data practices change materially.

7. How We Share Information

We do not sell personal information to third parties in exchange for money.

We may share information in limited circumstances, including:

• Service providers: With hosting providers, analytics services, advertising partners, and technical service providers that help us operate the website.

Third-party providers may process information according to their own privacy policies and contractual obligations.

8. Data Retention

We retain personal information only for as long as reasonably necessary for the purposes described in this policy, unless a longer period is required or permitted by law.

For example, we may retain messages for an appropriate period to respond to enquiries, maintain records, resolve disputes, or meet legal obligations.

Technical logs and analytics information may be retained according to the settings and policies of our hosting provider or relevant service providers.

Retention periods depend on the type of information and the reason it is collected.

9. Data Security

We take reasonable steps to protect information handled through our website against unauthorised access, loss, misuse, alteration, or disclosure.

However, no website, online service, or method of electronic storage can be guaranteed to be completely secure. We therefore cannot promise absolute security.
