Introduction

This Privacy Policy explains how RS-485.COM ("we", "us", or "the site") collects, uses, stores, and protects information provided by contributors, registered users, and visitors. By accessing or using this site, you agree to the practices described below.

RS-485.COM is committed to transparency and data minimization. This wiki is a technical resource, not a commercial service. We do not sell, rent, or trade personal data.

Definitions

• Visitor: Anyone who reads wiki pages without logging in.
• Contributor: Any user (registered or unregistered) who creates or modifies content. Unregistered contributors are identified by IP address.
• Registered User: Anyone with an active account (username + email).
• Administrator: Trusted user with access to certain site tools and logs.

Account Information

When you register, we collect:

• Username (publicly visible)
• Email address (private — used only for password reset, notifications, and administrative contact)

Cookies

RS-485.COM uses essential cookies for:

• Login sessions (keeping you logged in)
• Preferences (editor settings, diff view mode)
• CSRF protection (security)

No tracking, advertising, or third-party cookies are used. You can disable cookies in your browser, but login and editing will become difficult or impossible.
