Privacy Policy

1. Overview & Core Philosophy

At VividCalculator (accessible from https://vividcalculator.com), the privacy of our visitors is one of our highest priorities. This Privacy Policy document outlines the types of information collected and recorded by VividCalculator and how we protect your personal data.

Client-Side Processing Guarantee: All inputs typed into our calculator widgets (such as your weight, height, financial numbers, income, or dates) are processed locally within your browser environment using JavaScript. Your calculations are never submitted to or stored on our servers.

2. Log Files & Standard Web Technical Data

VividCalculator follows standard procedure for using log files. These files log visitors when they visit websites. The information collected by log files includes internet protocol (IP) addresses, browser type, Internet Service Provider (ISP), date and time stamp, referring/exit pages, and possibly the number of clicks. These are not linked to any information that is personally identifiable.

3. Cookies & Local Storage

Like any modern web application, VividCalculator uses essential first-party storage technologies:

• Theme Preference: We store your selected light or dark mode preference in browser localStorage so your visual settings persist across visits.
• Recent Tool History: To help you quickly access your favorite calculators, a brief list of recently opened tool slugs is stored locally in your browser.

4. Google DoubleClick DART Cookie & Third-Party Advertising

Google is a third-party vendor on our site. It also uses cookies, known as DART cookies, to serve ads to our site visitors based upon their visit to https://vividcalculator.com and other sites on the internet.

Visitors may choose to decline the use of DART cookies by visiting the Google Ad and Content Network Privacy Policy at the following URL: https://policies.google.com/technologies/ads.

5. Third-Party Analytics (Google Analytics)

We use Google Analytics (gtag.js) to understand aggregate traffic trends and overall site performance. Google Analytics collects non-personally identifiable metrics such as pageviews, average session duration, and device category (desktop vs. mobile). You can opt out of analytics tracking via standard browser extensions or privacy settings.

6. Children’s Online Privacy Protection Act (COPPA)

Another part of our priority is adding protection for children while using the internet. We encourage parents and guardians to observe, participate in, and/or monitor and guide their online activity. VividCalculator does not knowingly collect any Personal Identifiable Information from children under the age of 13.
