1. Zero-Log Computation Architecture
When you perform conversions on ToolBox24 (such as converting pressure, thermal energy, currencies, or developer hashes), the mathematical evaluation occurs strictly on your local device CPU/GPU using modern client-side JavaScript and WebAssembly. We do not log, inspect, monetize, or transmit your calculation inputs or output data.
2. Information We Collect
ToolBox24 collects only minimal operational telemetry required to deliver fast, secure edge delivery:
- Server Log Telemetry: Anonymized HTTP request headers (IP address, user agent, requested URL) collected by edge reverse proxies for DDoS mitigation, rate limiting, and infrastructure diagnostics.
- Client Preferences: Lightweight local storage keys and first-party cookies used exclusively to remember your chosen UI theme (dark/light mode, color palette) and display density preferences.
3. Cookies and Local Storage
We do not use intrusive third-party cross-site tracking cookies. ToolBox24 utilizes essential, strictly necessary local storage items and cookies to maintain accessibility configurations and session states across page navigations. You can clear or disable cookies via your browser settings at any time without impacting conversion features.
4. Data Security & Encryption
All traffic to ToolBox24 is encrypted in transit using industry-standard TLS 1.3 cryptographic protocols with modern cipher suites and Strict-Transport-Security (HSTS) headers, preventing eavesdropping and man-in-the-middle attacks.
5. Your Rights Under GDPR and CCPA
Under the EU General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA), you retain the right to access, rectify, or request deletion of any personal account data if you register for an optional account. Because guest users have zero stored calculation data, no engineering or conversion data exists to be shared or sold.
