Zero Server Logging

Privacy Policy

Your privacy is fundamental to 600IQ. Learn how our client-side architecture protects your personal information and calculation data.

Last updated: July 30, 2026 • Version 1.1

1. Introduction

Welcome to 600IQ ("we", "our", or "us"). We are committed to maintaining the privacy, security, and confidentiality of our users. This Privacy Policy explains our data collection practices when you visit our platform at 600iq.com and utilize our web calculators, converters, and engineering tools.

Summary: 600IQ does not transmit, store, or monitor your tool inputs or calculation results on any remote server. Everything happens on your own computer or mobile browser.

2. No Server-Side Calculation Logging

Unlike conventional web apps that send user inputs back to central servers for processing, 600IQ tools are engineered as pure client-side applications using JavaScript and WebAssembly.

  • Input Data: All measurements, dimensions, numbers, currency values, and custom configurations entered into 600IQ tools remain exclusively inside your browser memory.
  • Output Data: Results, generated blueprints, summaries, and downloadable reports are generated locally on your device.
  • No Database Storage: We do not operate databases to store user calculations or session histories.

3. Cookies and Local Storage

600IQ uses browser localStorage and standard cookies to ensure optimal functionality:

  • Theme Preference: We save your selected visual theme (Light Mode or Dark Mode) in your browser's localStorage key 'site-theme' so your setting persists across page reloads.
  • Calculation Persistence: Where supported, tools may save your non-sensitive session progress in local storage on your device so you do not lose your work upon refreshing.

4. Google AdSense and Third-Party Advertising

We may partner with third-party advertising networks, including Google AdSense, to serve advertisements when you visit 600IQ. These advertising partners help support our free tools and servers.

  • Advertising Cookies: Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites on the Internet.
  • Google Advertising Cookies: Google's use of advertising cookies enables it and its partners to serve ads to our users based on their visits to 600IQ and/or other sites across the web.
  • Personalized Advertising Opt-Out: Users may opt out of personalized advertising by visiting Google Ads Settings. Alternatively, you can opt out of third-party vendor cookies for personalized advertising by visiting www.aboutads.info or the Network Advertising Initiative Opt-Out Page.

5. Web Analytics & Infrastructure

We use privacy-centric web analytics tools (such as Google Analytics 4 via Google tag) and CDN hosting providers (such as Vercel and Cloudflare) to understand aggregated traffic patterns, popular calculators, and site performance. Standard, aggregated server logs (e.g., anonymized IP addresses, browser types, and requested URLs) are processed strictly for technical telemetry, security, and load balancing.

6. Third-Party Links & External Resources

Our web pages or tools may occasionally contain links to third-party websites or external documentation (e.g., standard specification bodies, GitHub, or font delivery networks like Google Fonts). We do not control or endorse the privacy practices of external sites. We encourage you to review the privacy policies of any site you visit.

7. Data Security

Because we do not store personal calculation records on backend databases, the risk of centralized data breaches is mitigated at the architectural level. All connections to 600IQ are secured using modern Transport Layer Security (TLS / HTTPS) encryption.

8. Children's Privacy

Our tools and calculators are intended for general audiences, professionals, students, and engineers. We do not knowingly collect personal information from children under the age of 13.

9. California (CCPA) and European (GDPR) Privacy Rights

Depending on your jurisdiction, you may have rights under the California Consumer Privacy Act (CCPA) or General Data Protection Regulation (GDPR) regarding the collection of your personal data and opt-outs for personalized advertising. You may exercise these rights at any time via the opt-out links above or by contacting us directly.

10. Updates to This Policy

We may update our Privacy Policy periodically to reflect enhancements to our platform. Any revisions will be published directly on this page with an updated revision date.
