Privacy Policy

1. Overview

Mat Grades is an open engineering reference portal. We respect your privacy and believe in transparency. This policy explains what information is processed when you visit and interact with matgrades.com.

2. Information We Do Not Collect

We do not require user accounts, passwords, payment details, or phone numbers to access material specifications, comparisons, tools, or downloads. Furthermore, because the contact form operates strictly as a local demonstration interface without a backend service, we do not collect, transmit, or store names, email addresses, or message contents submitted through the site.

3. Server Logs

Like standard web servers, our hosting infrastructure may temporarily log routine technical connection requests. These logs may include IP addresses, browser user agent strings, requesting URLs, and request timestamps. These logs are used strictly for technical performance monitoring, infrastructure stability, and defending against malicious traffic or denial-of-service attempts.

4. Cookies & Local Storage

Mat Grades does not use third-party advertising or commercial tracking cookies. We may use browser session storage or local storage exclusively to remember user interface preferences, such as selected unit systems (SI vs. Imperial) or comparison selections.

5. Contact Form Submissions (Demonstration Mode)

The contact form and data-issue reporting interface on matgrades.com currently operate as a demonstration and local UI component only. Messages and form inputs are not transmitted across the network, emailed to staff, persisted, or stored in any database or backend service.

Mat Grades does not collect, receive, store, or process personal data or inquiries submitted via this form until a dedicated, secure backend submission service is deployed. When backend processing is introduced, this policy will be updated prior to deployment to describe the exact transmission, storage, and retention mechanisms.

6. Analytics

If privacy-preserving, aggregated usage metrics are implemented in the future, they will focus strictly on technical performance and catalog utility without cross-site tracking or profiling.

7. External Links

Our catalog references external standards bodies (such as ASTM, CDA, SAE, and ISO) and publisher literature. When clicking external reference links, you are subject to the respective external website policies.

8. Questions & Policy Status

For questions regarding this privacy policy or site practices, refer to our contact page and engineering disclaimer.
