Privacy notice

When you submit a Sleep Detective email form, the name and email address you enter are sent directly to Kit, our email service provider, so we can deliver the requested material and related Sleep Detective emails. Kit also handles unsubscribe requests and email-delivery records.

The Sleep Sound Matcher stores your selected sound categories in your browser so it can order your recommendations and recover from accidental back navigation. It does not put your name or email address in the results URL, local browser selection record, or analytics event.

Basic campaign and page-interaction data may be measured through analytics already enabled on the site. Sleep Sound Matcher analytics events use category names only and must not contain an email address.

You may unsubscribe from marketing emails at any time using the link in an email. Clear this site’s browser storage to remove saved matcher selections from your device.

This concise notice describes the current Sleep Sound Matcher implementation. The site owner should have final privacy language reviewed for the business’s complete data practices and applicable law before paid traffic begins.
