Privacy Policy

This Privacy Policy explains what information Backyard Calculators collects, how we use it, who can see it and the choices you have. By using this website you agree to the practices described here.

Information we collect

Information you give us. When you use the contact form or join our email list, we receive your name, email address and message.

Feedback. If you tell us that a calculator was or was not helpful, we may record that choice together with the calculator name and your approximate country. We do not store your IP address with it.

Usage data collected automatically. Our servers and analytics tools may record pages visited, time on page, device type, browser, operating system, referring website and approximate location based on your IP address.

Calculator inputs. The numbers you type into a calculator are used in your browser to show your result. We do not ask for your name or address to use a calculator.

How we use information

• To reply to your messages and support requests.
• To send new calculators, guides and project tips, only if you joined our email list.
• To understand which calculators and pages are useful, fix problems and improve the site.
• To measure traffic and, where used, to show relevant advertising.
• To protect the site against spam, abuse and security threats.
• To meet legal obligations.

Legal bases for using your information

Where laws such as the GDPR apply, we rely on your consent (for example, email sign ups and non essential cookies), our legitimate interest in running and improving a safe website, and legal obligations. You can withdraw consent at any time.

Cookies and similar technologies

Cookies are small files stored on your device. We use them to remember your settings, such as light or dark mode, to measure traffic and, where enabled, to support advertising.

Third party vendors, including Google, may use cookies to show ads based on your visits to this and other websites. You can learn how Google uses data at policies.google.com/technologies/partner-sites and manage ad personalization at adssettings.google.com.

You can block or delete cookies in your browser settings. If you do, some features may not work as expected.

Analytics and advertising partners

We may use services such as Google Analytics and Google AdSense. These providers process data under their own privacy policies. We do not control their cookies, and we do not give them your name or email address.

Email list

If you join our email list, we use your address to send updates about new calculators, guides and project tips. Every email has an unsubscribe link, and you can also ask us to remove you at backyardcalculators@gmail.com. We do not sell or rent your email address.

Sharing of information

We do not sell your personal information. We share it only with trusted service providers that help us run the site, such as hosting, email delivery and analytics, with authorities when the law requires it, or with a buyer if the website is ever sold. These providers may use your data only to perform their services for us.

Data retention

We keep messages and email list details for as long as needed to reply and to send what you asked for, and delete them when you ask or when they are no longer needed. Analytics data is kept for the period set in our analytics tools.

Data security

We take reasonable technical and organisational steps to protect the information we hold, including secure connections and limited access. No online service is completely secure, so we cannot guarantee absolute security.

International visitors

Our website may be hosted and processed in countries other than yours. By using the site you understand that your information may be transferred to and handled in those countries.

Your rights and choices

Depending on where you live, you may have the right to access, correct, delete or export your personal information, to object to or restrict certain use, and to withdraw consent. Residents of California and some other regions may also have the right to know what is collected and to opt out of the sale or sharing of personal information. We do not sell personal information.

To make a request, write to backyardcalculators@gmail.com. We may ask you to confirm your identity first.

Children

This website is not directed to children under 13, and we do not knowingly collect their personal information. If you believe a child has sent us information, contact us and we will delete it.

Third party links

Our pages may link to other sites. Their privacy practices are their own, so please read their policies before you share information.

Changes to this policy

We may update this policy from time to time. The date at the top shows when it last changed, and we encourage you to review it now and then.
