Privacy Policy

Last updated: July 2026

This Privacy Policy explains how Keystone Building Supply LLC ("we", "us", or "our") handles the information you choose to provide through this website. Our website is a catalogue and enquiry service. It does not sell products online, does not process payments, and does not require you to create an account.

Who we are

Keystone Building Supply LLC is a building-materials supplier located at 4834 W Division St, Chicago, IL 60651. You can reach us by phone at 779-245-8764 or by email at support@keystonebuildingsupply.com.

Information we collect

We only collect the information you enter into our enquiry forms. Depending on the form, this may include:

• Your name and, if you provide it, your company name.
• Your contact details, such as email address and phone number, and your preferred contact method.
• Project information, such as customer type, project type, and a project address or ZIP code.
• The materials, estimated quantities, preferred date, and any additional details you describe.
• Whether you are enquiring about pickup or delivery.

We do not ask for sensitive personal information or payment details through this website, and you should not submit them.

Technical information

Like most websites, our hosting server may automatically record basic technical information in its logs, such as your IP address, browser type, and the pages requested. This is used to operate the site, keep it secure, and diagnose problems. To protect your privacy, our own security features (such as rate limiting) reference IP addresses only in a hashed form and do not retain them unnecessarily.

Why we use your information

We use the information you provide for a limited set of purposes:

• To review and respond to your enquiry or quote request.
• To send you a confirmation that we received your enquiry, when email is configured.
• To follow up on your enquiry and communicate about your project.
• To detect, prevent, and investigate fraud, spam, and threats to website security.

We do not use your information for unrelated marketing without your consent.

Cookies and session storage

This website uses a small number of strictly necessary cookies — principally a session cookie used for security features such as protecting our forms against cross-site request forgery. It does not track you across other websites. See our Cookie Policy for details.

Service providers and third parties

We do not sell your information. We rely on standard service providers to operate this website and to deliver enquiry messages — for example, our website host and our email/SMTP provider. These providers process information only as needed to provide their service to us. Our Contact page also embeds a Google Maps frame; when it loads, Google may receive technical information from your browser under Google's own privacy terms.

Data retention

We aim to keep enquiry information only for as long as we need it to respond to and follow up on your enquiry, and we try not to retain unnecessary personal information beyond that.

Data security

We use reasonable technical and organisational safeguards to protect the information submitted through this website, including HTTPS, protected forms, and rate limiting. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

Children's privacy

This website is intended for a general business audience and is not directed to children. We do not knowingly collect personal information from children.

External links

Our website may link to third-party websites and services that we do not control. This policy does not apply to those sites, and we encourage you to review their privacy practices.

Your choices

You can choose not to submit an enquiry form and instead contact us by phone or email. If you have submitted an enquiry and would like us to update or remove the details you provided, please contact us.

Changes to this policy

We may update this policy from time to time. The "last updated" date above shows when it was last revised.

Contact us

If you have any questions about this Privacy Policy or the information you have submitted, please email support@keystonebuildingsupply.com or call 779-245-8764.

This policy is provided for general information about how this website handles enquiry information. It is not legal advice and does not assert compliance with any specific law or regulation.
