Quote requests
If you use a "Get quotes" form, we collect what you enter: the service you need, your ZIP code, name, email, and optionally your phone number and a short note. We use it only to pass your request to up to 3 septic companies that serve your ZIP code, so they can contact you about a quote. You agree to this with the checkbox on the form. We never ask for ID numbers, permit numbers or payment details.
To have your request deleted, email hello@septicnumbers.com.
Analytics, advertising and affiliate links
We may use analytics to count page views, and our hosting provider keeps standard server logs. If we add ads or affiliate links, those partners may use cookies; we will name them here before they go live.
