Tool Input Data Policy

Crucial Privacy Guarantee: We want to be entirely transparent about the information you enter into our calculators and converters. Because our platform is built on client-side technology, ToolMatrix does not collect, store, or transmit any sensitive data you enter into our tools—including the Mortgage Calculator, FI/RE Planner, BMI Calculator, CGPA Converter, or Engineering Converter. All calculation processes occur solely within your web browser and are never sent to our servers.

This Usage Data may include information such as your computer's Internet Protocol address (e.g. IP address), browser type, browser version, the pages of our Service that you visit, the time and date of your visit, the time spent on those pages, unique device identifiers and other diagnostic data. This data is typically anonymous and aggregated.

Cookies are files with a small amount of data which may include an anonymous unique identifier. Cookies are sent to your browser from a website and stored on your device. Other tracking technologies are also used such as beacons, tags, and scripts to collect and track information and to improve and analyze our Service.

Sharing of Aggregated and Anonymized Information

We may share aggregated, non-personally identifiable data publicly and with our partners (such as business analysts or publishers). This information is solely used to show trends about the general use of our services—for instance, tracking the most popular unit conversions or average ROI metrics used in our tools—and cannot be used to identify any individual user.

Third-Party Advertising (e.g., Google AdSense)

We use third-party Service Providers like Google AdSense to show advertisements on our Service to help support and maintain our Service.

Google, as a third-party vendor, uses cookies (such as the DART cookie or other advertising cookies) to serve ads on our Service. Google's use of advertising cookies enables it and its partners to serve ads to our users based on their visit to our Service and/or other sites on the Internet.

Users may opt out of personalized advertising by visiting the Google Ad Settings page: https://adssettings.google.com/authenticated.

Affirmative Consent: Before collecting, processing, or disclosing personal data for personalized advertising or analytics purposes, we will provide you with clear notice and obtain your prior, affirmative (opt-in) consent. We ensure that any data shared with partners, including Google, is done in strict compliance with these regulations.
