Introduction
MyCompoundInterest.co is a free, static web tool built to help people understand compound growth without creating an account or sharing personal information.
We are committed to protecting your privacy and keeping the experience simple and transparent.
This Privacy Policy explains what data we collect, if any, and how we use it.
Data We Collect
We do not collect personal data that directly identifies you as an individual.
We use Google Analytics 4 to collect anonymised usage data such as pages visited, session duration, and approximate location at country level.
No personally identifiable information is collected, and IP addresses are anonymised.
All calculations happen entirely in your browser, and no calculator data is sent to any server.
Third-Party Services
We use Google Analytics 4, a web analytics service provided by Google LLC, to understand anonymous traffic patterns and improve the site.
The data collected through Google Analytics 4 may be transferred to Google servers in the United States under Standard Contractual Clauses.
