Privacy Policy

1. Client-Side Computational Privacy

At Combined Gas Law Calculator (https://combinedgaslawcalculator.net), privacy is engineered into our architecture. All thermodynamic mathematical evaluations—including initial pressure (P₁), initial volume (V₁), initial temperature (T₁), final pressure (P₂), final volume (V₂), and final temperature (T₂)—are executed exclusively within your client web browser through local JavaScript execution.

We do not transmit, log, inspect, analyze, or archive your scientific variables, lab measurements, or calculated solutions on our web servers or external cloud databases. Your computational workflows remain 100% private to your device.

2. Information We Collect and Receive

Because our tools operate without registration or subscriptions, the types of data we handle are strictly limited:

• Voluntary Correspondence: When you voluntarily submit an inquiry via our Contact Us form or direct email (semanticsearch.ai@gmail.com), we collect your name, email address, message subject, and inquiry details. This information is utilized solely to provide technical support, respond to bug reports, or answer scientific inquiries. We never sell, rent, or trade correspondence lists to third parties.
• Technical Server Logs: Like virtually all websites, our edge hosting infrastructure (Vercel) automatically records transient server-level operational metrics. These logs may include your device's truncated IP address, browser user-agent, operating system, requested URL path, referring URL, and access timestamp. These logs serve exclusively for network defense, DDoS mitigation, detecting server errors, and maintaining platform uptime.

3. Cookies and Client-Side Storage

We do not use invasive third-party tracking cookies or marketing pixels.

Our platform may utilize standard browser localStorage or session storage solely to preserve your non-personal computational preferences—such as your preferred default pressure/volume units or user-selected dark mode theme. This data remains entirely within your local device browser and can be cleared at any time through your browser settings.

4. Third-Party Service Providers

We partner with select industry-standard infrastructure providers to deliver a fast, secure website experience:

• Hosting & Content Delivery Network: Our website is hosted on globally distributed edge networks provided by Vercel Inc. Content delivery networks ensure minimal latency and high availability worldwide.
• Copyright & Verification Badges: Our website displays copyright protection status verified through DMCA.com. Interacting with third-party verification seals is subject to the respective provider's terms and privacy policies.

5. Data Retention & Security Protocols

We employ state-of-the-art security measures to safeguard communication integrity:

• Encryption in Transit: All HTTP network traffic between your browser and our edge servers is strictly encrypted using Transport Layer Security (TLS 1.3 / HTTPS).
• Contact Data Retention: Support emails and contact inquiries are retained only for as long as necessary to address your feedback or resolve reported issues, after which records are routinely purged.

6. Children's Online Privacy (COPPA Compliance)

Our site is an open educational and scientific utility designed for students, educators, and engineers. We do not intentionally target or collect personal identifying information from children under the age of 13. If you believe a minor has submitted personal contact details without parental consent, please contact us immediately for prompt deletion.

7. Your Privacy Rights (GDPR & CCPA/CPRA)

Depending on your geographic location (including the European Economic Area, United Kingdom, and State of California), you may hold statutory rights regarding any personal correspondence data we hold:

• Right of Access: You may request confirmation of whether we hold any contact emails or correspondence from you.
• Right to Rectification & Erasure: You may request correction of inaccurate contact records or immediate deletion of past inquiry messages.
• Right to Opt-Out of Sale: We do not sell or share personal data with data brokers or advertisers under any circumstances.

8. Policy Updates

We may update this Privacy Policy periodically to reflect technological adjustments, architectural enhancements, or metrological updates. Any modifications will be posted directly to this page with an updated effective date.
