Privacy policy

Effective date: November 8, 2026

This is our privacy policy and our notice to parents under the Children's Online Privacy Protection Act (COPPA).

The short version

Who we are

Zoorithmetic is operated by Hausbound, LLC, 1300 Rt 17 North Ste 1, Ramsey, NJ 07446. You can reach us by email at support@zoorithmetic.com or by phone at (201) 785-7309. In this policy, "we" and "us" mean Hausbound, LLC.

Zoorithmetic is made for children learning their math facts, so it is directed to children under 13. COPPA applies to it, and this policy is our notice to parents under that law.

This website

The free practice pages on this website need no sign-up, have no forms and do not set cookies, and the website has no analytics and no ads. They do not ask for any information about you or your child. A parent who creates an account or signs in, in the app or in the website's parent account area, gets one session cookie for that sign-in. It is strictly necessary to keep you signed in and is never used for tracking. Game progress is saved only in your browser, on your device, and is never sent to us. The site also keeps a copy of its pages on your device so practice works offline.

Like any website, our hosting provider receives the technical details your browser sends to load a page, such as your IP address. We do not use them to identify you. They are kept for up to 30 days.

If we start counting visits, we will count only totals per day, page and action (for example, a game started), with no IP address, cookie or identifier of any kind.

Later, this website will add a page where a parent can ask for an email when the app launches, and a page to buy the app as a gift. Both are for adults, and neither is on a page with a game or quiz.

Who will use the app

What we will collect about children

Only a parent can add a child to the family account, and we collect the minimum the app needs:

We will never ask for or store a child's real name, birth date, photo, voice, location or email address, and the app has no place to enter them.

What we will collect about adults

From parents:

The 4-digit parent PIN stays on your device. We do not keep your IP address or device details with your sign-in. To stop repeated requests, a scrambled form of the IP address is kept for up to 24 hours.

From a parent who asks to hear when the app launches: only an email address and when you signed up and confirmed.

From gift buyers: an email address, for the gift code and receipt, and the billing address our payment processor needs to calculate sales tax. A gift buyer is never asked about a child.

No information about a child reaches our server until a parent has read this notice in the app and given consent. We confirm consent this way: first you confirm your email address; then you give consent in the app; at least 24 hours later we email you to restate what we collect and how to withdraw consent and delete your child's information, with one link that does it.

A second parent confirms their own email address and gives their own consent before they can see any child's information.

If this notice changes, the app asks for your consent again before it backs up your child's practice.

You can withdraw consent at any time with the link in that email. If you are the only parent with a login, withdrawing consent deletes your family account right away, as described below. If another parent shares the account, it ends your own access, and the family and its children stay with the other parent, who gave their own consent.

Parental consent is the basis for everything we collect about a child. The only exception is the error report described below, which carries no identifier and is used only to keep Zoorithmetic working.

How we will use information

We will never sell your family's information, never show ads and never build advertising profiles.

Who sees your child's information

We never disclose a child's information to third parties. Inside the app, only the parents in your family can see it. An email that mentions a child goes only to a parent in that family who has confirmed their email address and given consent.

A parent can share a short progress summary (nickname, facts mastered, facts to work on and practice days) from their own device, for example with a teacher. It is made on your device, and we never receive the recipient's address. Copies you share are outside our control.

No ads and no tracking

There are no ads in Zoorithmetic. This website and the app contain no third-party advertising, analytics or tracking code.

This website will send us a short report when one of its pages hits an error, so we can fix it. The report carries no identifier of any kind: it has the error's name, a shortened message with anything that looks like an email address or a long number removed, the type of page, the site version and the day. It never includes cookies, your IP address, your browser or device type, or the address of the page you were on. We use these reports only to keep Zoorithmetic working, and we delete them after 90 days.

The app contains no crash-reporting code. We see only the crash reports that Apple and Google pass on to app developers.

Companies that help us run Zoorithmetic

We use a small number of service providers. Each receives only the information it needs to do its job for us.

We disclose information only when the law requires it. If Zoorithmetic is sold, we will tell parents first and give them the chance to delete their family's information, and any buyer must keep it under this policy. If Zoorithmetic closes, we delete all family information.

How long we keep information

Nothing about your child is kept forever.

Deleting your family's information

We confirm every deletion by email. Deleted information leaves our backup copies within 30 days. A purchase made in the App Store or Google Play can be restored to a new account; a purchase made on our website, or a redeemed gift, ends with the deleted account, and we tell you this before you confirm.

Your rights as a parent

You can also ask us to do any of these by email, mail or phone (see Contact us below). To protect your family, we confirm that a request comes from a parent: a parent can make it while signed in to the app, or reply from the email address on the family account. For a request by mail or phone, we confirm it by email to that address.

We will not ask a child for more information than practice needs, and a child never has to give information to practice.

How we will protect information

Only our own server can reach the database, and every request is checked to make sure it comes from a parent in that family. Our keys and passwords are kept apart from our code. Backups are encrypted and age out within 30 days. We will keep a written information security program and review it every year. You can read a summary of it on our security page.

United States only

Zoorithmetic is offered only in the United States, and purchases are available only to United States customers.

Changes to this policy

When we change this policy, we will post the new version here with a new effective date. In the app, each parent is asked to consent again before their child's practice is backed up again.
