Privacy Policy

1. Who We Are

ConstructionCalc ("we," "us," or "our") operates the website at yoursite.com (the "Site"). This Privacy Policy explains how we handle information in connection with your use of the Site.

If you have any questions or concerns about this policy, please contact us using the information at the bottom of this page.

2. Information We Do Not Collect

Our calculators run entirely in your web browser using JavaScript. We do not:

• Require you to create an account or log in
• Ask for your name, email address, phone number, or any personal identifiers
• Store, transmit, or retain any numbers you type into the calculator inputs
• Sell, rent, or share personal data with third parties for their marketing purposes
• Use tracking pixels tied to your personal identity

When you use the calculator, all computations happen locally on your device. No calculation inputs or results are ever sent to or stored on any server we control.

3. Information Automatically Collected

Like virtually all websites, our hosting provider's servers automatically log certain technical information when you visit the Site. This may include:

• Your IP address (used to route the page to your browser)
• Browser type and version
• Operating system
• Referring URL (the page you came from)
• Pages viewed and time spent on those pages
• Date and time of your visit

This information is collected automatically by our hosting provider (e.g., Netlify, Vercel, or GitHub Pages) for operational purposes. We do not use this data to identify you personally. Server logs are typically retained for a short period (usually 30–90 days) by the hosting provider.

4. Google AdSense and Advertising

This Site uses Google AdSense, a third-party advertising service operated by Google LLC. Google AdSense uses cookies, web beacons, and similar tracking technologies to serve advertisements based on your prior browsing activity on this and other websites across the internet.

What Google may collect through AdSense:

• Cookies identifying your browser across websites
• Your approximate location (based on IP address)
• Pages you visit and content you interact with
• Device type, browser, and operating system
• Demographics and interest inferences based on browsing history

Google's use of data collected through AdSense is governed by Google's Privacy Policy. We do not have access to or control over Google's data collection practices.

How to Opt Out of Personalized Ads

You have several options to limit interest-based advertising:

• Visit Google Ad Settings to opt out of personalized ads from Google
• Visit optout.aboutads.info to opt out of participating ad networks
• Visit optout.networkadvertising.org for the NAI opt-out tool
• Enable "Do Not Track" in your browser settings (note: not all advertisers honor this signal)
• Use your browser's private/incognito mode to prevent cookie storage

Note that opting out of personalized ads does not mean you will stop seeing ads — it means the ads you see will be less tailored to your interests.

5. Google Analytics

We may use Google Analytics to understand general traffic patterns on the Site — such as how many visitors we receive, which pages are most popular, and what devices visitors use. Google Analytics uses cookies to collect this aggregated, anonymized data.

We do not use Google Analytics to identify individual users. Data collected through Google Analytics is processed by Google according to their Privacy Policy.

You can opt out of Google Analytics tracking by installing the Google Analytics Opt-out Browser Add-on.

6. Cookies

Cookies are small text files stored on your device by websites you visit. Our Site itself does not set any first-party cookies for functional purposes (we have no login system, shopping cart, or preferences to save).

Third-party cookies may be set on your device by:

• Google AdSense — for advertising personalization
• Google Analytics — for anonymous traffic measurement

You can control cookie settings through your browser. Most browsers allow you to block or delete cookies. Note that blocking third-party cookies may affect the ads you see but will not affect the functionality of our calculators, which do not use cookies.

7. Children's Privacy

This Site is not directed to children under the age of 13. We do not knowingly collect or solicit personal information from anyone under 13. If you are under 13, please do not use this Site or provide any information on it.

If we learn that we have inadvertently collected personal information from a child under 13, we will take steps to delete that information as quickly as possible. If you believe a child under 13 has provided us with personal information, please contact us using the details below.

8. Your Privacy Rights

California Residents (CCPA)

Under the California Consumer Privacy Act (CCPA), California residents have the right to know what personal data is collected, the right to request deletion, and the right to opt out of the sale of personal data. We do not sell personal data. Since we collect no personal identifiers from calculator users, most CCPA rights are satisfied by design. For any requests related to data our hosting provider or advertising partners may hold, please contact us and we will direct your request appropriately.

European Union / EEA Residents (GDPR)

If you are located in the European Union or European Economic Area, you have rights under the General Data Protection Regulation (GDPR), including the right to access, rectify, erase, restrict processing of, and object to processing of your personal data. Since our calculators collect no personal data, there is generally no personal data for us to provide or delete. For data held by third parties (Google), please use Google's tools linked above or contact those parties directly.

For third-party cookie consent, we recommend EU/EEA users use a browser-level cookie control tool or privacy extension to manage consent for advertising cookies.

9. Third-Party Links

The Site may contain links to external websites (such as OSHA.gov or Google's opt-out pages). We are not responsible for the privacy practices or content of those sites. We encourage you to read the privacy policy of every website you visit.

10. Security

Since we do not collect or store personal data on our own servers, there is no personal data of yours at risk in the event of a breach of our systems. Our calculators operate entirely on the client side (your browser) and transmit no calculation data to any server.

We use HTTPS to ensure your connection to the Site is encrypted in transit. However, no method of transmission over the internet is 100% secure.

11. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or other factors. We will update the "Last Updated" date at the top of this page whenever we make changes. We encourage you to review this page periodically.

Continued use of the Site after any changes to this Privacy Policy constitutes your acceptance of the updated policy.

12. Contact Us

If you have any questions, concerns, or requests related to this Privacy Policy or how we handle data, please contact us:

We will respond to privacy-related inquiries within a reasonable time frame. For requests related to data held by Google or other third parties, we will direct you to the appropriate opt-out tools and contact channels.
