Privacy Policy

1. Overview & Commitment to Privacy

Core Concept Learning ("we", "us", "our") operates coreconceptlearning.com (the "Site"). We provide free engineering tutorials, courses, and system architecture guides. We believe education should be accessible, and we design our site to collect minimal personal data.

This Privacy Policy explains what information is collected when you visit our website, how that information is processed, how third-party advertising partners (including Google AdSense) use cookies, and how you can exercise your privacy rights under global data protection regulations (including GDPR, UK GDPR, and CCPA/CPRA).

2. Information We Collect & How We Collect It

We do not require user account registration, credit cards, or passwords to access our articles and courses. Information collected falls into the following categories:

• Usage & Diagnostic Analytics: When analytics is active, we collect anonymous, aggregate telemetry such as pages viewed, time spent per page, referring URLs, browser type, operating system, and approximate country/region (derived from anonymized IP addresses). This helps us identify popular topics and fix broken navigation.
• Browser Local Storage: User preferences (such as light/dark mode theme selection and course lesson completion status) are stored entirely in your local browser storage (`localStorage`). This data remains on your physical device and is never transmitted to or stored on our servers.
• Voluntary Communications: When you send us an email or submit a correction through our contact channels, we receive your email address, name (if provided), and message contents solely for the purpose of responding to your inquiry. We never sell, rent, or trade email addresses.

3. Cookies & Advertising Technologies (Google AdSense Disclosure)

Cookies are small text files stored on your browser by websites you visit. We and our third-party service providers use cookies to analyze site traffic and serve relevant advertisements that fund our free learning resources.
