Privacy Policy

1. Data Minimization & Pure Client-Side Computation

Biggan.me does not require user accounts, registration, login credentials, or the submission of personally identifiable information (PII) such as real names, phone numbers, or residential addresses.

All scientific equations, matrix operations, quadratic formulas, chemical reaction inputs, and code simulator inputs are computed strictly client-side within your browser's JavaScript sandbox. Your numerical inputs and equations are never transmitted to, inspected by, or stored on our servers.

2. Browser LocalStorage Practices

To enhance usability across study sessions without requiring account synchronization, we store minimal non-personally identifiable keys in your browser's localStorage:

• theme: Retains your selected color mode (Dark vs. Light).
• biggan_consent: Stores your cookie preference selection ('all' vs. 'essential').
• ssc_progress_*: Stores offline study checklist milestones on the Revision Progress dashboard.

These items reside exclusively on your physical device. You can erase them at any time by clearing your browser's site data or cookies.

3. Google AdSense & Third-Party Advertising Cookies

To sustain server operating expenditures and ensure our computational tools remain freely accessible worldwide, we partner with third-party advertising vendors, including Google LLC (Google AdSense).

Google and certified third-party ad networks utilize HTTP cookies (such as the __gads, __gpi, and DoubleClick cookies) to serve programmatic advertisements based on prior visits to this website and other domains across the web.

Your Privacy Choices & Opt-Out Controls:

• You may opt out of personalized ad targeting by visiting Google's official Google Ads Settings.
• You can opt out of third-party behavioral tracking cookies via the Digital Advertising Alliance at aboutads.info or the European Interactive Digital Advertising Alliance at youronlinechoices.eu.
• You can reconfigure your preferences at any time by clicking the "Cookie Settings" trigger located in our website footer.

4. Performance Analytics & Diagnostic Telemetry (GA4)

We utilize Google Analytics 4 to collect aggregated, anonymized telemetry metrics (such as device viewport categories, browser rendering engines, and page load latency). This telemetry enables us to diagnose Core Web Vitals bottlenecks on cellular data networks. We do not transmit PII or mathematical calculation variables to analytics platforms.

5. Children’s Privacy Safeguards (COPPA & GDPR-K)

Biggan.me is a general educational resource. We do not intentionally solicit, harvest, or retain personal data from children under 13 years of age (or under 16 in applicable European jurisdictions). If a parent or guardian discovers that a child has provided personal contact details inadvertently, please alert us immediately for prompt deletion.

6. Contact Information & Data Inquiries
