Who we are

Builder AI Tools (builder-ai-tools.com) is operated by FOM – Fidex Orbis Mercatus, the data controller for this website. Contact us about privacy at hello@builder-ai-tools.com.

What we collect

No accounts. You do not need to sign up or give any personal details to use the calculators.
Your calculations stay on your device. The calculators run in your browser; the numbers you type are not sent to us.
Technical data. Our hosting provider, Cloudflare, processes data such as IP addresses and browser type to deliver pages and protect the site from abuse.
Email. If you email us, we use your message and address only to reply, and delete correspondence when it is no longer needed.

Advertising

We show ads from Google AdSense. Google and its partners may use cookies and similar technologies to show ads and measure them, including ads based on your previous visits to this and other websites, where you have agreed to that. Visitors in the UK, EEA and Switzerland are asked for their choice through a consent message before personalised ads are shown. You can change your choice at any time through the "Privacy and cookie settings" link that the consent tool shows, manage ad personalisation at adssettings.google.com, and read how Google uses data from partner sites.

Legal basis

We rely on your consent for advertising cookies, and on our legitimate interest in running a secure, working website for the technical data our host processes.

Your rights

Under UK GDPR you can ask for access to, correction of or deletion of your personal data, object to processing, and withdraw consent at any time. Email hello@builder-ai-tools.com. You can also complain to the Information Commissioner's Office at ico.org.uk.
