Privacy Policy

Last updated November 10, 2026

Human Atlas is a site for taking personality tests and seeing how you and the people close to you compare. It is run by Z21 Partners in Ontario, Canada (“we”). This policy explains what we collect, why, who sees it, and the choices you have.

Human Atlas is only offered to people in Canada and the United States. It isn’t offered in the European Union, the United Kingdom or anywhere else, so please don’t use it from there.

What we collect

• Your Google account details. When you sign in with Google we receive your name, email address and profile picture. We don’t get your password, and we don’t ask for your contacts, files or anything else in your Google account.
• Your answers and results. What you enter in a test, the results it gives you, and when you took it. Personality answers can be sensitive, so please only enter what you’re comfortable sharing.
• People and groups. The groups you make, and the names, relationships and age bands (child, teen or adult) of the people you add. Someone you add gets a guest profile with a personal link, and doesn’t need an account.
• What people say about each other. Some tests let you answer about someone else, or answer about yourself with a particular person in mind. Those answers are about that person as well as you.
• Your date of birth, only to check your age at sign-in. We don’t store it.
• Technical information. A cookie that keeps you signed in, a cookie that records for a day if a date of birth was under 13, and the basic server logs (such as IP address and pages requested) that our host keeps. We don’t use advertising or analytics cookies.

How we use it

• To run the site: to sign you in, save your answers, show your results, and share them in the ways you choose.
• To improve the tests and the product. Our administrators can see individual answers, including who gave them, and use them for this. This may change in future, and we’ll update this policy if it does.
• For research into personality and relationships, and to develop new tests.
• For marketing: to understand who uses Human Atlas and to promote it. Anything we publish uses combined or de-identified findings. We won’t publish your name or your individual answers without your permission.

We don’t sell your personal information. We don’t use information from your Google account for advertising.

Who can see it

• Other people on the site see what you choose to share with them, such as your result on a test you take together or compare. A group sees the result, not your individual answers, unless a test says otherwise when you choose.
• Our administrators, as described above.
• Service providers who work for us:
  • Render, which hosts the site and its database.
  • Google, for sign-in. Pages also load fonts from Google, which sends Google your IP address.
  • Anthropic, whose AI assistant Claude our team uses to build tests and analyse results. Results, including who gave them, can be sent to Claude when we do this.
• Authorities, if the law requires it.

These providers may process and store information in Canada, the United States or elsewhere, where local law applies to it.

Children

You must be 13 or older to sign in yourself. We ask for your date of birth at sign-in to check this, and we don’t keep it. A child under 13 can only take part through a parent or guardian: the adult adds them, and enters their answers or sits with them on the adult’s own sign-in. Children under 13 don’t get a personal link. The adult must have the authority to do so and is responsible for what’s entered. By adding a child, the adult consents to us collecting and using their information as this policy describes.

We don’t knowingly let anyone under 13 sign in or give us information themselves. People marked as a child or teen are not used for marketing, and are used for research only in combined or de-identified form. They are not shown views of themselves written by others.

A parent or guardian can delete a child’s data at any time: open the child on Your people and choose Delete their data. You can also email info@z21partners.com. If you think a child has given us information without an adult’s involvement, please tell us and we’ll delete it.

How long we keep it

We keep your information until you delete it or ask us to. Deleted data can stay in our database backups for a limited time until those backups expire.

Your choices and rights

You can download a copy of your answers, or delete your account and data, yourself at any time under Your data. You can also ask us for a copy of your other information, ask us to correct it, or withdraw a consent you gave, by emailing info@z21partners.com. We reply within 30 days.

In Canada you can complain to the Office of the Privacy Commissioner of Canada. In the United States, your state’s privacy law may give you further rights, and you can use the same address to exercise them.

Changes and contact

We’ll post changes here and update the date above, and tell you on the site if a change is significant. Questions: info@z21partners.com.
