Necessary storage

The site may use browser storage for basic site behavior. This includes remembering that the cookie notice was acknowledged and keeping the contact thank-you page from behaving like a normal public landing page.

This storage helps the site work normally and keeps repeat visitors from seeing the same notice every time they open the site.

Google measurement

The site uses Google Ads and Google Analytics. These tools help Elwin understand page performance, phone and email clicks, contact form activity, and advertising conversion measurement.

This measurement is important for understanding which ads and pages produce qualified requests, so Elwin can improve its Google Ads account and avoid wasting budget on low-quality traffic.

Marketing attribution

The site may store campaign details from the current visit, including Google click IDs, GBRAID, WBRAID, and UTM parameters. These details help connect a contact request to the page or campaign that brought the visitor to the site.

If a visitor submits the contact form, saved attribution may be included with the request so Elwin can understand how the inquiry reached the site.

Browser and account controls

Visitors can use browser settings, browser extensions, device settings, or Google account controls to block or delete cookies, local storage, and advertising identifiers.

More information about personal information handling is available in the Privacy Policy.

Plan the system around the property.

Security systems integration and installation should start with the building conditions, not a disconnected product list.
