Privacy Policy

1. Introduction & Scope

Welcome to CompoundInterestCalculator.cc (referred to as "the Website," "we," "us," or "our"). We are committed to protecting the privacy and personal safety of our visitors. This Privacy Policy is designed to inform you about the types of information we collect when you visit and use our online tools, how we handle that data, and the strict technical safeguards we maintain to keep your personal browsing experience anonymous and secure.

This policy applies solely to information collected by this Website. It does not apply to third-party portals, services, or plug-ins that you may access through hyperlinks found on our pages. By continuing to use and access CompoundInterestCalculator.cc, you explicitly accept the terms, guidelines, and disclosures described in this comprehensive policy document.

2. The Calculations run Local (No Data Transmitted)

First and foremost: We do NOT collect, store, or transmit the financial numbers you enter into our calculator.

Unlike many other modern web applications that send user inputs to a remote server for processing, the CompoundInterestCalculator.cc engine runs **100% client-side in your own web browser**. Every value you type—including your starting principal, recurring contributions, estimated interest rates, and regular withdrawals—is processed locally on your own machine using standard Vanilla JavaScript.

Because we do not have a backend database to store these entries, it is physically impossible for us or any malicious actor to access your calculated financial pathways, net worth projections, or target retirement goals. Your session is completely safe, insulated, and private from third-party observation.

3. Automatically Collected Network Data

When you navigate our website, our server infrastructure and analytics tools automatically record standard server log information. This data is non-personally identifiable and is collected to evaluate overall site performance, diagnose server issues, and defend against malicious cyber attacks.

Through Google Analytics, we collect aggregate, anonymous statistics about our overall traffic flow. This recorded data includes:

• Technical Environment details: browser type, operating system, device screen resolution, and device type (desktop, tablet, or smartphone).
• Traffic Referral details: the referring website URL from which you arrived at our site (such as organic search results or external links).
• Engagement metrics: the specific sub-pages you visited, the duration of your session, the approximate date and time of access, and general page loading speeds.
• Approximate Location: IP-derived country-level or region-level coordinates. We do not track precise GPS or street-level locations.

4. Cookies & Tracking Technologies

Our Website uses cookies to deliver standard features and optimize performance. Cookies are small, lightweight text files that are stored directly in your browser's local cache. They allow us to recall specific client settings (such as keeping a chosen chart view active) and help us understand general navigation paths.

In addition to performance cookies, we integrate third-party services that utilize cookies for tracking and advertising purposes:

• Google Analytics Cookies: Google Analytics places persistent cookies in your browser to monitor visitor trends, calculate returning users, and generate aggregate usage graphs. No personal information is associated with these analytics profiles.
• Google AdSense & Advertising Cookies: Google AdSense and its network of third-party vendors use "DoubleClick DART" cookies to serve targeted ads on our pages. These cookies are served based on your previous visits to this site and other websites across the internet, enabling personalized ad targeting.

How to opt-out: You have the complete right to control cookies. You can configure your browser to decline all cookies, block third-party trackers, or alert you when a cookie is being transmitted. Additionally, you can opt-out of personalized advertising by visiting the official Google Ads Settings portal or using consumer block tools like the Network Advertising Initiative (NAI) opt-out page.

5. Third-Party Services in Use

To keep our platform fast, accessible, and sustainable, we leverage trusted industry-standard service providers. These platforms maintain their own distinct privacy policies:

• Google Analytics: We use Google Analytics to monitor traffic behavior. For more information on how Google manages and processes this data, you can consult Google's official document: How Google uses data when you use our partners' sites or apps.
• Google AdSense: We display display ads through Google AdSense to offset operational costs. Google and its certified partners may use cookie technologies to deliver and personalize ads. You can audit Google's comprehensive privacy standards here: Google Privacy Policy.

6. How We Use the Collected Data

The anonymous aggregate information we gather is utilized solely for technical optimization and educational content expansion. Specifically, we use this data to:

• Evaluate site engagement and optimize user interfaces for mobile devices and tablets.
• Debug performance bottlenecks, such as slow chart rendering or layout shifts on certain browsers.
• Track which content topics and articles (such as 401k or CD guides) receive the most attention, helping us guide future educational updates.
• Personalize display advertisements served through Google AdSense, once advertising modules are activated on the domain.

We will never sell, lease, rent, or trade your anonymous browsing patterns or server log profiles with third-party data brokers or marketing firms.

7. Data Retention Disclosures

Standard network server log entries are retained in our hosting provider's secure partitions for a period of up to 90 days to diagnose infrastructure issues and defend against security breaches. After this time window, standard log tables are systematically purged.

Google Analytics aggregate traffic histories are retained on Google's secure storage systems under standard retention intervals. Because no personal data is saved, these trends do not pose a threat to user anonymity.

8. GDPR & CCPA Disclosures (EU & California Visitors)

For visitors accessing our platform from the European Union (subject to the General Data Protection Regulation - GDPR) or California (subject to the California Consumer Privacy Act - CCPA), we act as a "Data Controller" regarding standard analytics traffic.

Because we do not store, request, or handle personal names, email addresses, phone contacts, or physical locations, we are unique in maintaining an inherently "privacy-by-default" footprint. You have the right to opt-out of cookie tracking, purge existing cookies from your local cache, and request an audit of our anonymous database structures.

To exercise your GDPR or CCPA rights, you can configure your browser to reject all cookie transmission and contact our team to audit any aggregate statistics linked to your network IP.

9. Children's Privacy Safeguards (COPPA Note)

Our Website is designed strictly as a general-audience educational financial utility. We do not knowingly collect, request, or maintain information from children under the age of 13, in strict compliance with the Children's Online Privacy Protection Act (COPPA). If a parent or guardian believes that a child has transmitted network analytics information to our database, they can contact us to systematically purge that information from our system immediately.
