1. Introduction
Welcome to Online Concrete Calculators (“we”, “us”, “our”), available at onlineconcretecalculators.com (the “Website”). We provide free online concrete and cement calculators and educational articles about concrete, cement and related construction topics.
This Privacy Policy explains what information we collect, how we use and share it, how we use cookies and advertising technologies, and what choices and rights you have. By using the Website, you acknowledge that you have read this policy. Where the law requires your consent (for example, for non-essential cookies in the European Economic Area, the United Kingdom and Switzerland), we will ask for it separately and you can change your choice at any time.

We do not knowingly collect sensitive personal information such as financial account details, government ID numbers, precise location or health information.
3. How We Use Your Information
We use information to:
- Operate, maintain, secure and improve the Website, our calculators and our content
- Understand how visitors use the Website through analytics
- Show advertising, including personalized advertising where permitted by law and your choices
- Respond to your messages, comments and requests
- Detect and prevent spam, fraud and abuse
- Comply with legal obligations and enforce our terms
4. Legal Bases for Processing (EEA, UK and Switzerland)
If you are in the EEA, UK or Switzerland, we process personal data on these legal bases:
- Consent: for non-essential cookies, personalized advertising and analytics cookies where required (you may withdraw consent at any time)
- Legitimate interests: to operate and secure the Website, prevent spam and understand site performance, where these interests are not overridden by your rights
- Contract or pre-contract steps / legal obligation: where we respond to your requests or must comply with the law
5. Cookies and Similar Technologies
Cookies are small text files stored on your device. We also use similar technologies such as web beacons, pixels and local storage. We use:
- Essential cookies: needed for the Website to function and remember your cookie choices.
- Analytics cookies: help us understand how the Website is used (for example, Google Analytics).
- Advertising cookies: used by Google and other partners to show and measure ads and, where permitted, to personalize them.
You can control cookies through your browser settings (blocking or deleting them may affect parts of the Website) and, where we display a cookie banner, through our cookie preferences tool. Visitors from the EEA, UK and Switzerland will see a consent banner before non-essential cookies are set. You can change or withdraw your cookie choices at any time using the “Cookie Settings” link in the footer of the Website.
6. Google AdSense and Advertising Partners
We use Google AdSense to display ads. Google and other third-party vendors use cookies and similar technologies to serve ads based on your prior visits to this Website and other websites on the internet. Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visit to our Website and/or other sites.
Third-party vendors, including Google, may collect and use data such as your IP address, cookie and device identifiers, and information about your browsing activity for ad delivery, measurement, fraud prevention and personalization. We do not control these third parties or the content of their ads.
Your choices:
- Turn off personalized ads in Google’s Ads Settings: https://adssettings.google.com
- Learn how Google uses information from sites that use its services: https://policies.google.com/technologies/partner-sites
- Opt out of third-party vendors’ personalized advertising: https://www.aboutads.info/choices and https://optout.networkadvertising.org (users in Europe may also use https://www.youronlinechoices.eu)
- Use your device settings to limit ad tracking on mobile devices
Opting out does not stop ads from appearing; it means the ads you see will be less relevant to your interests.
For users in the EEA, UK and Switzerland, ads personalization and the use of cookies for advertising happen only in line with the choices you make in our consent banner. You can read more in Google’s Privacy Policy: https://policies.google.com/privacy
7. Google Analytics
We use Google Analytics to measure traffic and improve our content. Google Analytics uses cookies and similar identifiers to collect information such as pages visited, approximate location, browser, device type and how you arrived at the Website. This data is used in aggregated reports and does not directly identify you to us, but it is collected using pseudonymous identifiers and is processed by Google.
You can opt out by installing the Google Analytics Opt-out Browser Add-on: https://tools.google.com/dlpage/gaoptout. Learn more about how Google uses this data at https://policies.google.com/technologies/partner-sites.
8. How We Share Information
We do not sell your personal information for money. We share information only with:
- Service providers: hosting, security, analytics, email, comment and spam-filtering providers, who process data on our behalf
- Advertising and analytics partners: such as Google, as described above
- Legal and safety: where required by law, court order or to protect rights, safety and security
- Business transfers: in the event of a merger, sale or transfer of the Website, subject to this policy
Because advertising partners may collect identifiers for ad targeting, certain US state laws may treat this as “sharing” or “selling” of personal information for targeted advertising. See Section 12 for your choices.
9. International Data Transfers
We and our service providers (including Google) may process data in countries other than your own, including the United States. Where required, we rely on appropriate safeguards such as Standard Contractual Clauses or other lawful transfer mechanisms.
10. Affiliate Links and Sponsored Content
Some articles may contain affiliate links. If you click a link and make a purchase, we may earn a commission at no extra cost to you. Affiliate and sponsored content is clearly disclosed within the relevant content. Affiliate networks may place cookies on your device to track referrals.
11. Third-Party Links
The Website may link to external websites. We are not responsible for their content or privacy practices, and we encourage you to read their privacy policies.
12. Your Rights and Choices
All visitors: you may ask us to access, correct or delete personal information we hold about you, and you may opt out of personalized advertising as described in Section 6.
EEA, UK and Switzerland (GDPR): you have the right to access, rectify, erase, restrict or object to processing of your personal data, to data portability, and to withdraw consent at any time (without affecting earlier processing). You also have the right to lodge a complaint with your local data protection authority.
California and other US states (CCPA/CPRA and similar laws): depending on where you live, you may have the right to know what personal information we collect, use and disclose; to request deletion or correction; to opt out of the “sale” or “sharing” of personal information for targeted advertising; and to not be discriminated against for exercising these rights. We honor opt-out preference signals such as Global Privacy Control where required. To opt out of personalized advertising, use the cookie preferences link on our Website or the Google and industry opt-out tools listed in Section 6.
To exercise any right, email support@onlineconcretecalculators.com. We may need to verify your identity before acting on your request and will respond within the time required by applicable law (generally 30 to 45 days).
13. Data Retention
We keep personal information only as long as needed for the purposes in this policy or as required by law. As a general guide: contact emails are kept for up to 24 months after our last correspondence; comments remain until you ask us to remove them or we delete them; Google Analytics data is retained for 14 months (the retention period configured in our account); cookies expire according to their type, usually between a session and 24 months.
14. Security
We use reasonable technical and organizational measures, including HTTPS encryption, to protect your information from unauthorized access, loss or misuse. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.
15. Children’s Privacy
The Website is not directed to children under 13 (or under 16 where local law sets a higher age), and we do not knowingly collect their personal information or show them personalized ads. If you believe a child has provided us with personal information, please contact us and we will delete it promptly.
16. Changes to This Privacy Policy
We may update this policy from time to time to reflect changes in our practices, technology or legal requirements. When we do, we will change the “Last Updated” date at the top of this page. Where required by law, we will seek your consent again or give additional notice. Please review this page periodically.
