Privacy Policy

Welcome to Master Calculate. Your privacy is very important to us. This Privacy Policy explains what information Master Calculate does and does not collect, how we use it, and what rights you have regarding your data.

Master Calculate was built with privacy in mind. We do not store any personal data on our servers. When you use our calculators — such as the BMI calculator or the Currency Converter — all computations happen directly in your web browser.

We do not collect or ask for:

• Names or email addresses
• IP addresses for tracking purposes
• Financial records or sensitive health data

To provide a better experience, Master Calculate saves some non-personal preferences on your device. These include:

• Theme Preferences: We remember whether you prefer Light or Dark mode.
• UI State: We remember whether you expanded or collapsed content panels or FAQs.

This data is stored only in your browser's Local Storage or via simple cookies — our servers cannot read it.

Master Calculate uses third-party advertising network Adsterra to display advertisements across our website. These ads enable us to keep all calculators and financial tools completely free for all users without any subscription fees.

• Adsterra serves standard contextual advertisements based on general region (GEO) and device type without tracking your cross-site personal identity.
• No personal account information, names, or email addresses are stored or collected by Adsterra through Master Calculate.
• You can manage non-essential analytics tracking anytime using our built-in Cookie Consent Manager.

Master Calculate may update this Privacy Policy from time to time. We encourage you to review this page periodically for any changes. Updates will be posted on this page and become effective immediately upon publication.
