    Privacy Policy

    Last updated: June 2025

    Overview

    CompoundCalc (https://growmymoney.app) is a free online calculator. We are committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights.

    Calculations and Your Financial Data

    All calculations are performed entirely in your web browser using JavaScript. No financial inputs, results, or personal data are sent to our servers. We have no access to the numbers you enter into the calculator.

    Local Storage

    If you use the "Save" feature, your calculator inputs are stored in your browser's localStorage. This data never leaves your device and is not accessible to us. You can clear this data at any time by clearing your browser's site data or using the calculator's reset function.

    Analytics

    We use Google Analytics 4 to understand how visitors use our website. This service collects anonymised data such as pages visited, time on site, and device type. Analytics data is processed by Google in accordance with their privacy policy. Analytics tracking is subject to your consent preferences.

    Advertising

    We display advertisements through Google AdSense to support the free operation of this website. Google may use cookies and similar technologies to serve ads based on your interests, subject to your consent preferences. If you decline personalised advertising, Google will serve non-personalised (limited) ads instead.

    Contact Form

    Our contact form uses EmailJS to send messages directly to our email address. The information you provide (name, email, message) is transmitted via EmailJS's servers and delivered to us by email. We do not store contact form submissions in a database. We will only use your email to respond to your enquiry.

    Cookies and Consent

    We use Google's Consent Management Platform (CMP) to manage your privacy preferences. On your first visit, you'll be asked to consent to cookies for analytics and advertising. You can change your preferences at any time by clicking "Manage privacy" in the footer.

    Third-Party Services

    • Google Analytics 4 — website usage analytics
    • Google AdSense — display advertising
    • EmailJS — contact form delivery

    Each service has its own privacy policy. We encourage you to review them.

    Your Rights

    Under UK GDPR and the Data Protection Act 2018, you have the right to access, correct, or delete any personal data we hold. Since we don't store personal data from calculator usage, this primarily applies to any contact form correspondence. To exercise your rights, email us at [email protected].

    Changes to This Policy

    We may update this policy from time to time. Changes will be posted on this page with an updated "Last updated" date.
