What we collect

The sizing calculator runs in your browser. We do not collect your contact information unless you choose to submit the optional installer quote form.

The installer quote form collects only the contact and project details you submit, such as name, email, phone, ZIP code, homeowner status, project scope, current heating, and project timeline. It also attaches the calculator result so installers can understand the size range you saw.

Qualified quote requests may be stored in Airtable and emailed to Splitsizer for manual review. When an installer marketplace is active in your area, we may share your submitted details with up to 3 local installers so they can contact you about the project.

Analytics

We use Vercel Web Analytics and Vercel Speed Insights to measure aggregate page performance and traffic patterns. No personally identifying information is collected by these tools.

Cookies

Splitsizer itself does not set tracking cookies. Outbound links to Amazon may include affiliate tags, and Amazon will set its own cookies if you click through.

Your data, your rights

To request deletion of any contact-form or quote-request data you have submitted, email hello@splitsizer.com from the address you submitted. We'll remove your record within 7 days.
