Privacy Policy

Keystone Systems ("Keystone," "we," "us," or "our") operates builtbykeystone.net and related pages. This Privacy Policy explains how we collect, use, and share information when you visit our website or contact us.

This site is a marketing website for our business. We do not sell products or services directly through the site, and we do not operate user accounts on this website.

Information you provide voluntarily. If you use our contact form, you may choose to include your name, business name, email address, phone number, current website, and a message describing what you need. Submitting the form opens a prefilled email in your email app. Nothing is transmitted to us until you send that email.

Information collected automatically. Like most websites, our hosting infrastructure may log technical data when you visit, such as your IP address, browser type, device type, referring page, and the pages you request. We use this information to operate, secure, and troubleshoot the site.

We use contact information to respond to inquiries, evaluate potential projects, and communicate with you about our services.

We use automatically collected technical data to maintain site performance, diagnose problems, and protect against abuse or unauthorized access.

We do not use your information for targeted advertising on this website.

We do not sell your personal information.

We may share information with service providers that help us operate the website, such as hosting and infrastructure providers. Those providers process information on our behalf and only as needed to provide their services.

We may disclose information if required by law, regulation, legal process, or to protect the rights, property, or safety of Keystone Systems, our clients, or others.

This website does not use advertising or analytics cookies.

We store your light/dark theme preference in your browser's local storage so the site remembers your display choice on return visits. You can clear this preference by clearing site data in your browser settings.

If you contact us by email, we retain messages and related correspondence for as long as needed to respond, maintain business records, and comply with legal obligations.

Server logs are retained for a limited period consistent with our hosting provider's practices and operational needs.

You may choose not to submit information through our contact form or by email.

If you have previously contacted us, you may ask us to stop further marketing communication by replying to our message or emailing hello@builtbykeystone.net.

If you are a California resident, you may have additional rights under the California Consumer Privacy Act (CCPA), including the right to know what personal information we collect, request deletion of personal information we maintain about you, and not be discriminated against for exercising these rights. We do not sell personal information. To make a privacy request, contact us at hello@builtbykeystone.net.

Our website is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us personal information, contact us and we will take appropriate steps to delete it.

We may update this Privacy Policy from time to time. When we do, we will revise the content on this page. Continued use of the website after changes are posted constitutes acceptance of the updated policy.
