4. How we share information
We do not sell your personal information for money. We may share information with:
- Service providers who help us operate the Site and business (for example, email delivery, hosting, analytics, and advertising partners), under obligations to protect the information
- Advertising and analytics partners such as Google, which may receive online identifiers and event data when their tags run on the Site

Quote and contact submissions are typically routed to our sales team (for example, via our email delivery provider) so we can respond to your request.
5. Cookies, analytics, and advertising
This Site uses Google advertising and related technologies, including the Google tag (gtag.js) associated with our Google Ads account. We may also use Google Analytics or similar tools when configured.
These technologies may set or read cookies and collect information about your visits to this Site and other sites in order to:
- Measure conversions and campaign performance for Google Ads
- Understand how visitors use the Site
- Build audiences and show relevant ads on Google services and partner sites
- Limit how often you see our ads
Google and other third parties may use cookies, web beacons, and similar technologies to collect or receive information from this Site and elsewhere on the internet and use that information to provide measurement services and target ads. You can learn more about how Google uses data at https://policies.google.com/technologies/partner-sites and manage ad personalization at https://adssettings.google.com. You may also visit the Network Advertising Initiative opt-out page at https://optout.networkadvertising.org and the Digital Advertising Alliance page at https://optout.aboutads.info. Browser settings can block or delete cookies; doing so may affect Site functionality.
6. Do Not Track and browser signals
Some browsers offer a “Do Not Track” setting. There is no consistent industry standard for responding to these signals. Aside from tools and settings described in this Policy (such as cookie controls and ad personalization settings), we do not currently respond to Do Not Track browser signals in a differentiated way.
7. Data retention
We retain personal information for as long as needed to fulfill the purposes described in this Policy, including responding to inquiries, maintaining business records, meeting legal or accounting requirements, and resolving disputes. Advertising and analytics data may be retained by our providers according to their own retention schedules and settings we configure.
8. Security
We use reasonable administrative, technical, and organizational measures designed to protect personal information. No method of transmission over the internet or electronic storage is completely secure, and we cannot guarantee absolute security.
9. Children’s privacy
The Site is intended for business and professional users. We do not knowingly collect personal information from children under 16. If you believe a child has provided us personal information, contact us and we will take appropriate steps to delete it.
10. International visitors
We are based in the United States. If you access the Site from outside the United States, you understand that your information may be processed in the United States and other countries where our service providers operate, which may have different data protection laws than your jurisdiction.
11. Your choices and rights
Depending on where you live, you may have rights to access, correct, delete, or obtain a copy of certain personal information, or to opt out of certain processing (including targeted advertising) where applicable law provides those rights.
California residents may have additional rights under the California Consumer Privacy Act (CCPA/CPRA), including the right to know categories of personal information collected, request deletion, and opt out of “sale” or “sharing” of personal information for cross-context behavioral advertising, subject to exceptions. You may exercise applicable rights by emailing us at the address below. We will not discriminate against you for exercising privacy rights.
