This policy explains what information is processed when you visit Calcula tu Proyecto (calculateproyecto.com), how we use cookies and third-party advertising, and what options you have to control your data.

Site owner

Calcula tu Proyecto is a site of free calculators for estimating construction and gardening materials. For any privacy-related inquiry you can write to us at hello@dxperiments.com.

Data we process

We do not ask you to register nor do we directly collect identifiable personal data such as your name, address, or phone number. Calculations are performed locally in your browser: the measurements you enter in the calculators are not sent to our servers nor stored permanently.

However, as on most websites, when you browse certain technical data (such as your IP address, browser and device type, and pages visited) is automatically processed through our hosting provider and the third-party services described below.

Advertising: Google AdSense

This site displays ads through Google AdSense, a Google advertising service. To show ads, Google and its partners may use cookies and similar identifiers.

• Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this and other websites.
• Google's advertising cookies (such as the DoubleClick cookie) enable Google and its partners to show more relevant ads based on your interests.
• Google may process data such as your IP address and browsing activity to personalize and measure ads.

You can learn more about how Google uses data when you use its partners' sites or apps at policies.google.com/technologies/partner-sites.

How to control personalized ads

You can opt out of Google personalizing the ads you see by adjusting your Google Ads Settings. You can also disable the use of third-party advertising cookies by visiting www.aboutads.info or youronlinechoices.eu (Europe). In addition, you can control or delete cookies from your browser settings.

Cookies

We use technical cookies necessary for the basic operation of the site and third-party cookies related to the advertising described above. You will find the details in our cookie policy.

Our pages may include links to external sites (for example, manufacturers or material suppliers). We are not responsible for the privacy practices of those sites; we recommend that you review their policies.

Depending on your country of residence, you may have the right to access, rectify, or delete your data, as well as to object to certain processing. To exercise these rights or resolve any questions, write to us at hello@dxperiments.com.
