This Privacy Policy explains how CalcBoy collects, uses, protects, and processes information while providing free engineering calculators and technical resources worldwide.
Transparency, user privacy, and computational security guidelines across all CalcBoy tools and resources.
1. Overview & General Scope
At CalcBoy.com (accessible via https://calcboy.com), protecting your privacy is one of our priorities. This Privacy Policy document outlines the types of non-personal and personal information that is collected, processed, and recorded by CalcBoy and explains how we protect that information.
This policy applies solely to online activities on CalcBoy.com and is valid for visitors to our website with regards to the information that they share or collect in connection with our engineering tools, calculators, technical references, and blog articles.
2. Client-Side Calculation Privacy
CalcBoy is designed with a privacy-first engineering architecture. Most calculations across our platform—including component sizing, trace impedance parameters, and filter design values—execute locally inside your web browser via client-side JavaScript.
🔒 Privacy Protection: Your mathematical inputs, custom design variables, resistance values, and operational metrics are processed locally in your browser session. CalcBoy does not store, harvest, or transmit your proprietary circuit parameters to external servers.
3. Information We Collect
Because CalcBoy is an open technical reference platform, you can utilize our full suite of calculators without registering for a user account, providing credit card details, or revealing your identity.
Creating an account is not required to use the vast majority of calculators and tools available on CalcBoy.
We only receive personally identifiable information (PII) when you voluntarily choose to contact us directly:
- Direct Communications: If you send us an email or submit a contact inquiry via our Contact Page, we may receive your name, email address, message contents, and any attachments or technical screenshots you provide.
- Voluntary Feedback: Bug reports, calculator requests, or technical suggestions submitted voluntarily by users.
4. Log Files & Server Diagnostics
CalcBoy follows standard web server logging procedures. These log files record non-personal technical data when visitors access web pages. The information collected includes:
- Internet Protocol (IP) addresses (anonymized where required by law)
- Browser application type and version
- Internet Service Provider (ISP)
- Date and timestamp of page visit
- Referring and exit URL pages
- Aggregate click counts and device category (desktop, tablet, or mobile)
This technical log data is strictly used for analyzing server performance, preventing malicious bot activity, optimizing layout speed, and administering website security. Log data is not linked to any personally identifiable information.
5. Website Analytics
CalcBoy may use website analytics services, such as Google Analytics or similar technologies, if enabled, to understand website usage, improve performance, and enhance the overall user experience. These services collect aggregated, non-personally identifiable information and do not directly identify individual users.
