Privacy policy

What we collect, why, who helps us handle it, and the choices you have.

Last updated: October 22, 2026 · Version: 2026-10-22

1. Who we are and what this covers

MightyBuilder (we, us) operates this website, our documentation, and the service at app.mightybuilder.ai (together, the Service). This policy explains how we handle personal information about our customers and the people who visit our own websites.

Customers decide what their websites contain and what they collect from their visitors. For that information, the customer is responsible, and we handle it on the customer's behalf to host and deliver their site. If you visited a site built with MightyBuilder, that site's own privacy notice applies, and questions about it should go to its owner.

2. Information we collect

  • Account information, such as your name, email address, sign-in details and account settings. We never store a password in readable form.
  • Content you create, such as your sites, pages, files and images, settings, domains, revisions, and your conversations with the AI, including prompts and what it produced.
  • Payment information, such as your plan, purchases, billing details and transaction records. Card payments are handled by our payment processor, and we do not receive full card numbers.
  • Usage and device information, such as your IP address, approximate location, browser and device, the pages you visit, the actions you take, and diagnostic records.
  • Communications, such as support requests, the messages and files you send us, and our replies.
  • Information from others, such as sign-in providers you choose to use, our payment processor, and advertising platforms that tell us an ad led you to us.
  • Information about visitors to customer sites, such as request and usage information and anything a site's forms collect, which we handle for the customer as described in section 1.

3. How we use it

We use personal information to:

  • provide, operate and maintain the Service, including hosting and publishing sites;
  • carry out AI and image requests you make;
  • process payments, plans and credits;
  • communicate with you about your account, the Service and support requests;
  • send news about MightyBuilder, which you can stop at any time;
  • understand how the Service is used, and improve it;
  • measure the performance of our own marketing and advertising;
  • keep the Service and its users safe, detect and prevent fraud and abuse, and enforce our terms; and
  • meet legal, tax and accounting obligations, and establish or defend legal claims.

Where the law requires a legal basis, we rely on performing our contract with you, our legitimate interests in running, securing and improving the Service, compliance with law, and your consent where we ask for it.

4. AI processing

When you make an AI request, we send what is needed to carry it out, such as your prompt, the relevant conversation and site content, and any files or images involved, to third-party AI providers. We do not use your prompts or content to train AI models. Providers may keep limited records for safety, abuse prevention and legal compliance.

Do not put sensitive personal information into a prompt or a site unless you are entitled to and it is needed for what you are asking.

5. Who we share it with

We share personal information only as follows:

  • Service providers who work for us, such as hosting, storage and delivery, AI, payment processing, email delivery, analytics, advertising measurement and security services. They receive what they need to do that work.
  • Other people on a site: if you share a site with others, they can see the site's content and history.
  • For legal reasons, where we believe it is needed to comply with law or legal process, protect anyone's rights, safety or property, or investigate fraud, abuse or security issues.
  • In a business transfer, such as a merger, financing, reorganisation or sale of all or part of the Service.
  • With your consent or at your direction.

We do not sell personal information for money. When an ad brings you to us, we tell the advertising platform whether it led to a sign-up, to the first time you published your site, or to a purchase, using an identifier the platform supplied. Some privacy laws treat that as sharing for advertising, and you can opt out as described in section 6.

6. Cookies and similar technologies

We use cookies and similar technologies that are needed to sign you in and run the Service, and others that help us understand how our websites and the Service are used and measure our advertising, including tools provided by Google. Our sign-up and sign-in pages use Cloudflare Turnstile to tell people from automated abuse, which reads information about your browser and device for that purpose. You can block or delete cookies in your browser, though parts of the Service may not work without the necessary ones. We honour Global Privacy Control signals for advertising measurement.

Customer sites may use their own cookies, analytics and third-party services, which their owners choose and are responsible for.

7. Where it is processed

We and our providers process information in the United States, and may do so in other countries. It may be subject to the laws of those places, including lawful access by their authorities. Where the law requires, we use appropriate safeguards for these transfers.

8. How long we keep it

We keep personal information for as long as needed for the purposes in this policy, which for most account and site information is while your account or site is open. After that we delete or de-identify it, except where we need to keep it for legal, tax, security or dispute reasons. Copies may remain in backups for a limited period before they expire.

9. Security

We use administrative, technical and physical safeguards suited to the information we hold. No system is completely secure, and we cannot guarantee the security of information. If an incident affects your personal information, we will notify you and the authorities where the law requires.

10. Your choices and rights

Depending on where you live, you may have the right to access, correct or delete your personal information, to receive a copy, to object to or restrict some uses, to withdraw consent, and to complain to a privacy regulator. To make a request, including a request to close your account, email hello@mightybuilder.ai from your account's address. We may need to verify your identity, and we will respond within the time the law requires. Some information may be kept where the law allows, and deleting an account does not delete a site that other people also manage.

You can unsubscribe from news about MightyBuilder at any time with the link in each email. We will still send the messages your account needs, such as security, billing and service notices.

In Canada, you may contact the Office of the Privacy Commissioner of Canada. In the UK or the European Economic Area, you may contact your data-protection authority.

11. Children

The Service is for people 18 and older, and we do not knowingly collect information from children. If you believe a child has given us personal information, contact us and we will delete it.

12. Changes to this policy

We may update this policy. We will change the date and version above, and if a change materially affects how we use your information, we will tell you by email or through the Service before it takes effect.
