The numbers you enter into the calculators (square footage, project type, material grade, location) are computed entirely in your browser and are never transmitted or stored. We do collect anonymous, aggregate usage data through privacy-respecting analytics, described in Section 3. We do not collect names, addresses, or any personally identifiable information.
2. Calculations & Data
All renovation cost estimates are calculated locally in your browser using JavaScript. No renovation area, project type, or budget data is sent to any server. Your inputs stay on your device.
