This page tells you what information Kmath collects, why we collect it, and what we do with it. We do not sell your data. We do not share it with advertisers.
When you use Kmath, we collect:
We use your information to:
We do not use your child's assessment data for advertising. We do not sell your data. We share data with third parties only when needed to run the service, such as payment processing and cloud storage.
Your child's assessment data, check-in results, and roadmap are stored in your portal. This data is used only for your child's program. It is never shared with other families.
If you cancel, your data is retained for 90 days. At the 60-day mark, we send a reminder email. After 90 days, personal identifiers are removed and assessment records are anonymized. If you return after cancelling, a new $69 DCAR is always required regardless of how long you were away. This is because the monthly subscription includes the DCAR recalibration. If you did not pay that month, you did not receive it. A new DCAR is how the program restarts accurately.
If you want your data deleted before 90 days, you can request it through the Support page.
We use cookies to remember your login and preferences. We do not use advertising trackers.
All data is stored on encrypted servers. The first time you log in, you use a magic link sent to your email. After that, you create a password and sign in with your email and password like any normal account. Passwords are stored as encrypted hashes. We never store or see your plain-text password. If you forget your password, you can reset it by requesting a new link to your email.
Kmath has four separate portal types.
Parent portal: The primary account. Created with email and password, activated through a magic link on first login. The primary parent sees all enrolled children, manages billing, and controls all permissions.
Student portal: Students do not need an email address. Every student receives a unique ID in the format BP-XXXXXXX. The BP prefix is pre-filled at login. The student enters their 7-digit number and a 4 or 6 digit PIN. This ID appears on every document Kmath sends. The PIN can be changed by the student or by the primary parent. Students log in independently to take check-ins, access lessons, and track their progress.
Co-parent or family member portal: The primary parent can create one additional adult account. Permissions are set by the primary parent. This account can view the child's progress and watch check-ins but cannot access billing information.
Teacher or IEP coordinator portal: Created by the primary parent with permission controls they set. Teachers can upload curriculum directly to Kmath and view the child's roadmap and progress. IEP coordinators can view adapted reports and track goal progress. Neither can see billing or personal family information.
Kmath is bought by a parent or guardian and used by that parent's child. Many of the children who use Kmath are under 13. Because of that, information we collect from a child is governed by the Children's Online Privacy Protection Act, a United States federal law.
A child does not create a Kmath account on their own. You create the account, and you give your child access to it. You give consent when you create the account and start the assessment; before that point we have collected nothing from your child. You can withdraw consent at any time by contacting us, and we will stop collecting and delete what we hold, except anything we must keep by law.
We do not ask a child for an address, a phone number, or any contact detail. We do not use your child's information to advertise to them, and we do not allow anyone else to. We will not require your child to give us more information than is reasonably necessary to use Kmath.
We do not sell it and we never use it for advertising. We share it only with providers who run the service for us, and each may use it only on our instructions:
We use no third-party analytics or error-monitoring service. We will also disclose information if the law requires it, or to protect the safety of a child or another person.
You may ask to see everything we hold about your child, ask us to delete it, or refuse to let us collect anything further. Contact us using the address at the end of this page. We will confirm you are the parent on the account before acting.
Kmath is sold to parents, not to schools. We do not contract with schools or districts, and we do not rely on a school to give consent on a parent's behalf. If a teacher is involved, it is because a parent invited them.
