1. No Financial Data Collection
All calculations on InterestCompound.com are performed entirely within your browser. We do not transmit, store, or process any financial inputs you enter — such as principal amounts, interest rates, or contribution values — on our servers.
2. Analytics
We use Google Analytics 4 (GA4, property ID G-L8ZEZLEVKH) to understand aggregate traffic patterns such as page views, referral sources, and device types. GA4 collects anonymized interaction data using cookies. No personally identifiable financial information is transmitted to Google. You may opt out by using browser extensions such as the Google Analytics Opt-out Add-on.
3. Cookies and Local Storage
We use your browser's localStorage solely to remember your calculator preferences (e.g., dark/light mode, last-used inputs) between sessions. This data never leaves your device.
4. Third-Party Services
We use Google Analytics 4 for site analytics. Google may collect limited data per their own privacy policy. Fonts are self-hosted (we do not load them from any third-party CDN). We do not integrate any advertising networks or data brokers.
5. Children's Privacy
Our service is not directed at children under 13. We do not knowingly collect any information from children.
6. Changes to This Policy
We may update this privacy policy from time to time. Changes will be reflected by the "Last updated" date above. Continued use of the site after changes constitutes acceptance.
