Privacy Policy

Effective Date: January 1, 2026
Last Updated: August 28, 2026

EstiMate Civil ("we," "our," or "us") respects your privacy and is committed to explaining clearly how information may be collected, used, stored, and shared when you use our website and online civil engineering and construction estimation tools.

This Privacy Policy applies to information processed through the EstiMate Civil website, including our calculators, informational pages, contact functionality, analytics services, advertising services, cookies, and browser-based storage technologies.

Information We Collect

Depending on how you use the website, different types of information may be processed.

• Calculator Inputs: Numerical values and project parameters entered into our calculators are generally processed within your browser to produce the requested calculation. We do not intentionally collect or store your private engineering project inputs on our servers unless a particular feature specifically states otherwise.
• Technical and Usage Information: Like most websites, our website and third-party services may process technical information such as IP address, browser type, device type, operating system, approximate location derived from IP address, referring pages, pages viewed, and date or time of access.
• Cookies and Similar Technologies: We and our third-party service providers may use cookies, pixels, web beacons, local storage, and similar technologies to provide website functionality, remember preferences, understand website usage, and support advertising.
• Contact Information: If you voluntarily contact us, we may receive information that you provide, such as your name, email address, and the contents of your message. This information is used to respond to your enquiry and communicate with you.

Browser Storage and localStorage

Some EstiMate Civil features may use browser localStorage or similar browser storage mechanisms to remember non-sensitive preferences. Examples may include selected measurement units, currency preferences, interface settings, calculator preferences, or cookie-consent choices.

These preferences are stored locally in your browser and can generally be removed by clearing your browser's stored site data. We do not use localStorage to intentionally store passwords, payment information, or other sensitive personal information.

Google Analytics

We may use Google Analytics, including Google Analytics 4 (GA4), to understand how visitors use the website and to improve the performance, content, navigation, and usability of our calculators and informational pages.

Google Analytics may process information such as pages visited, approximate geographic information, browser and device information, interaction events, traffic sources, and other usage information. Depending on the configuration of the service and applicable consent requirements, cookies or similar technologies may be used.

Analytics information is processed by Google according to Google's applicable privacy policies and terms. We use analytics information primarily in aggregated or statistical form to understand website performance and user engagement.

Google AdSense and Advertising

EstiMate Civil may display advertisements through Google AdSense and other advertising partners. Advertising services may use cookies, web beacons, device identifiers, IP addresses, or similar technologies to deliver, measure, limit, and improve advertisements.

Google and its advertising partners may use information about a user's visits to this website and other websites to provide advertising that may be relevant to the user's interests, subject to applicable settings, consent requirements, and regional regulations.

• Personalized Advertising: Where permitted and where the required user consent has been obtained, advertisements may be personalized based on information associated with a user's browsing activity.
• Non-Personalized Advertising: Depending on user preferences, consent status, location, and advertising configuration, non-personalized advertisements may be displayed instead.
• Advertising Cookies: Google and its advertising partners may use cookies or similar technologies to serve, measure, and report on advertisements.
• Third-Party Vendors: Third-party advertising providers and ad networks may participate in serving advertisements on this website and may process information according to their own privacy policies.

Users can review or manage certain Google advertising preferences through Google My Ad Center.

Additional information about how Google uses information from websites and applications that use its services is available in Google's published privacy documentation.

How We Use Information

Information processed through the website may be used for purposes such as:

• Providing and operating our calculators and website features.
• Remembering user preferences and settings.
• Understanding website traffic and calculator usage.
• Improving website content, performance, usability, and navigation.
• Detecting security issues, abuse, spam, or fraudulent activity.
• Responding to messages and support requests.
• Displaying, measuring, and improving advertising where applicable.

Data Sharing and Third-Party Services

We do not sell your personal information as a standalone commercial database.

However, information may be processed by third-party service providers that help operate, analyze, secure, or monetize the website. These services may include analytics providers, advertising providers, hosting infrastructure, security services, and other technical service providers.

Third-party providers may process information according to their own privacy policies and applicable legal requirements.

Data Retention

We retain information only for as long as reasonably necessary for the purpose for which it was collected, including providing services, responding to enquiries, maintaining security, complying with legal obligations, and maintaining appropriate business records.

Information processed by third-party services such as Google Analytics or advertising platforms may be retained according to the respective service's settings, policies, and applicable retention controls.

Browser-based preferences stored through localStorage generally remain on the user's device until they are removed by the user, the website changes the relevant storage, or the browser's site data is cleared.

Cookies and Consent

Cookies and similar technologies may be used for essential website functionality, preferences, analytics, security, and advertising.

Where applicable, we provide users with choices regarding non-essential cookies and advertising technologies. The availability and operation of consent controls may vary depending on the user's location and applicable privacy regulations.

Users can also manage cookies through their browser settings. Disabling certain cookies may affect some website functionality.

International Users and Regional Privacy Requirements

EstiMate Civil may be accessed by users from different countries. Privacy and consent requirements vary between jurisdictions.

Where applicable, we aim to configure analytics, advertising, and consent mechanisms in accordance with relevant privacy and data-protection requirements.

For users in regions where consent is required before certain advertising or analytics technologies are used, the applicable consent mechanism may determine which technologies and processing activities are enabled.

Your Privacy Choices and Rights

Depending on your location and applicable law, you may have rights relating to your personal information. These may include the right to request access to, correction of, deletion of, or information about the processing of your personal information.

You may also have choices regarding cookies, analytics, and personalized advertising.

To exercise a privacy-related request, please contact us through our Contact Us page. We may need sufficient information to verify and respond to your request.

Data Security

We use reasonable technical and organizational measures intended to protect information processed through the website. However, no internet transmission or electronic storage system can be guaranteed to be completely secure.

Children's Privacy

EstiMate Civil is an educational and professional civil engineering resource and is not intentionally designed to collect personal information from children. We do not knowingly request or collect personal information from children for unnecessary purposes.
