This policy explains how GrowCompass ("we", "us", "this site") collects, uses, and protects information when you visit. By using the site you agree to the practices described here.
The compound interest calculator runs entirely in your web browser with JavaScript. The starting balance, contributions, rates, and goals you type are never transmitted to our servers, never stored, and never linked to you. You can use the tool without entering any personal information at all.
Like most websites, we may receive standard technical data through cookies and analytics, such as:
We use Google Analytics to understand aggregate traffic and how the site is used. It collects standard log and behaviour data and reports it in aggregate. We do not tie this data to your identity, and the calculator itself sends no personal data to analytics.
To learn more about how Google uses data, visit Google's Privacy & Terms page.
You can control or delete cookies through your browser settings. Disabling cookies will not stop you from using the calculator, though it may limit ad personalisation and some analytics.
If this site later serves ads through Google AdSense, third-party vendors including Google may use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalised advertising via Google Ads Settings. Ads never affect the calculator's maths, and your inputs are never shared with advertisers.
This site may link to external resources. We don't control those sites and aren't responsible for their privacy practices. Review each site's policy before providing information.
This site is intended for a general audience. We do not knowingly collect personal information from children under 13. If you believe a child has provided us personal information, contact us and we'll delete it promptly.
We may update this policy as features or services change, and will revise the "Last updated" date above. We encourage you to review this page periodically.
