Privacy Policy

Overview

NerdCalc is built to be useful without asking for unnecessary personal information. Most calculator use does not require an account, and we try to keep collection limited to the data needed to run the site, understand usage, and support advertising where it appears.

This policy covers the website, calculator tools, support pages, and related content published under the NerdCalc name.

Information We Collect

We may collect basic usage information such as pages visited, browser type, device type, approximate location derived from IP address, and referral data. Where you enter calculator inputs, the values may be processed in your browser or on our server to return a result, depending on the tool.

We do not build calculator features that require you to submit sensitive personal data. If you choose to enter sensitive information into a calculator, do so only if you are comfortable with that input being processed to generate the result.

How We Use Information

We use information to operate the site, improve performance, fix bugs, understand which tools are useful, and deliver ads or analytics where enabled. We also use it to protect the site from abuse, debug errors, and improve content relevance.

Cookies And Similar Technologies

We use cookies and similar technologies for essential site features, remembering preferences, analytics, and advertising. The site includes a cookie banner so users can acknowledge the use of cookies in a lightweight way without blocking normal access.

You can control cookies through your browser settings, but disabling them may affect saved preferences or some ad-related behavior.

Google AdSense And Advertising

NerdCalc may show ads through Google AdSense and other ad technologies. Google and its partners may use cookies, mobile identifiers, or similar technologies to serve and measure ads, limit frequency, and personalize advertising where permitted.

Google may receive or infer information about visits to this site and other websites. If you want to manage ad personalization, review Google Ads Settings and the ad controls available in your browser or device.

Analytics And Measurement

We may use analytics tools to understand aggregate traffic patterns, page performance, and feature usage. That information helps us improve layout, reduce friction, and prioritize calculators that people actually use.

Browser Storage

Some features use local storage or similar browser storage to keep preferences such as recent activity, dismissed banners, or interface state. This data stays on your device unless your browser clears it.

Sharing And Third Parties

We may share limited data with service providers that help us run the site, provide ads, or measure performance. Those providers process data under their own terms and privacy policies. We do not sell calculator input data as a product.

Data Retention

We keep basic usage and diagnostic information only as long as needed for operations, security, legal obligations, and reporting. Retention periods may differ depending on the type of data and the provider involved.

Your Choices

You can manage cookies, reset browser storage, and limit ad personalization through your browser or device settings. You can also review Google’s ad settings where applicable. If you want to request help with data-related questions, use the Support page.

Security

We use reasonable technical and organizational measures to protect the site and the information it processes. No internet service is perfectly secure, so we cannot guarantee absolute security.

Children

NerdCalc is not directed at children under the age where parental consent is required by local law for online data collection. If you believe a child has provided personal information through the site, contact us and we will review the request.

Changes To This Policy

We may update this policy when our tools, advertising stack, analytics setup, or legal obligations change. If we do, we may revise the effective date and keep the current version on this page.

This policy is a practical site template and should be reviewed by qualified legal counsel before relying on it as a final compliance document.
