Privacy policy

Information you provide

Calculator inputs may be recorded in aggregate to improve estimates. If you choose to save an estimate, we collect the email address, postal code, name, notes, calculator inputs, and marketing preference you submit. Do not include sensitive personal information in the notes field.

Advertising and cookies

Third-party vendors, including Google, may use cookies, web beacons, IP addresses, or similar identifiers to serve, measure, and personalize advertising based on visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visits.

You can manage personalized Google advertising in Google Ads Settings. Where required, a consent message lets you choose how advertising data is used before eligible ad technology loads.

Analytics

We may use Google Analytics to understand page visits, calculator completion, result types, and outbound link use. Analytics is used to improve the site and does not receive the email, name, postal code, or notes entered in the save-estimate form.

How information is used

• Provide calculator results and saved estimates.
• Improve cost ranges, site performance, and usability.
• Measure advertising and partner-link performance.
• Send promotional offers only when you explicitly opt in.
• Detect abuse and meet legal or regulatory obligations.

Retention and requests

Information is retained only as long as reasonably needed for these purposes. To ask about, correct, or delete information you submitted, email [email protected]. We may need enough information to identify the relevant record.
