This Privacy Policy applies to 9line.com, the equipment listing marketplace operated by 9LINE. It covers visitors, buyers, and sellers in the United States. Read it with our Terms of service.

This policy explains what information we collect, how we use it, who we share it with, how long we keep it, and how to reach us. If you have trouble reading this page, email support@9line.com. We post material changes here.

What information do we collect?

Depending on how you use the site, we may collect:

  1. Listing information, such as the title, description, photos, videos, manufacturer, location, and contact details you submit when listing equipment.
  2. Inquiries, such as your name, email, phone, and message when you contact a seller through a listing form.
  3. Account information, if you sign up: your email, name, profile fields you choose to add, and preferences such as notification settings.
  4. Activity, such as listings you manage while signed in, watchlist saves, and basic view counts for listings.
  5. Sign-in data, such as identifiers and session cookies used to keep you logged in.
  6. Technical data, such as your IP address and similar request data used for security, rate limiting, and operating the service.
  7. Support messages, including the content of emails or other messages you send to us.

How do we use your information?

We use this information to:

  1. Publish and display listings on the marketplace.
  2. Deliver seller inquiries, including by email.
  3. Operate accounts, watchlists, and other signed-in features.
  4. Keep the site secure and enforce our terms.
  5. Respond to support requests.
  6. Send service-related notices. We do not charge for listings today.

Do we use cookies?

We use cookies and similar technologies to keep you signed in, protect against abuse, and support basic site features such as counting listing views. You can control cookies in your browser, but some features may not work if you disable them.

With whom do we share your information?

  1. Sellers. When you submit an inquiry, we share what you entered so the seller can respond.
  2. Other visitors. Listing content and contact details you place on a listing are visible on the site.
  3. Service providers. Companies that help us host, authenticate users, send email, and run the platform, under obligations to protect your data.
  4. Legal requirements. When required by law, or to protect users and the platform.

We do not sell your personal information.

How long do we keep information, and how do we protect it?

We keep information while needed to operate the service and meet legal obligations, then delete or de-identify it when no longer needed. We use reasonable measures to protect data, but no online service is completely secure.

What are your choices?

You can update profile information in your account settings. To ask about access, correction, or deletion of your data, contact us. The site is not intended for children under 16.
