TheSiteMath publishes construction calculators, guides, and planning content for U.S. contractors and homeowners. Most calculator use happens in your browser. We collect personal information only when you choose to send it to us.
What You Choose to Submit
We collect information only when you send it.
- Messages submitted through the contact page
- Project submissions from calculator pages
- Any notes, timeline, budget, ZIP code, or estimate details you include
This may include your name, email address, phone number, and project details.
What Stays on Your Device
Many calculator actions happen entirely in your browser. We may store the following locally on your device:
- Saved calculations and recent calculator inputs
- Cookie consent preferences
- Theme or unit preferences where supported
Calculator data stays on your device unless you choose to submit it.
Cookies, Analytics, and Advertising
We always use essential storage so the site can remember settings such as saved calculations and cookie choices.
If you grant consent through our cookie controls, we may enable analytics and advertising storage for services such as Google Analytics and Google AdSense.
- Essential storage: keeps site features working
- Analytics storage: helps us understand site use
- Advertising storage: supports ad delivery and measurement
You can change your choice later through the Cookie Settings link in the footer.
How We Use Information
We use submitted or stored information to:
- Run and improve calculators, guides, and site features
- Reply to messages or review project submissions
- Understand which planning problems users need help with
- Measure site performance, subject to your consent choice
- Protect the site against abuse, errors, and unauthorized access
- Comply with legal obligations
How We Share Information
We may share limited information with:
- Infrastructure providers: hosting, database, and delivery services
- Analytics or ad partners: such as Google services when you allow them
- Legal authorities: when required by law or needed to protect our rights
We do not sell your personal information. We do not run a contractor marketplace, and we do not share project submissions with contractors by default.
Retention and Security
We keep submitted information only as long as it is reasonably needed for support, operations, review, or legal reasons. We use reasonable safeguards, but no online system is 100 percent secure.
