Safety & Privacy

Three kinds of thing:

• Account details — name, email, date of birth (used to decide which consent rules apply), grade level, and the link to your parent account or their teacher’s class.
• What happens during tutoring — the messages between your child and the tutor, the problems they work, which skills they have mastered and which are shaky, and any photos of homework they upload.
• Learning profile — interests they tell the tutor about (so word problems can use them), reading level, and any IEP accommodations a teacher has set.

We do not collect a home address. Payment details go directly to Stripe and are never stored on our servers.

No. We do not train any model on student data, and the AI providers we send text to — OpenAI, Anthropic and Mathpix — are used under their business API terms, under which customer data is not used to train their models.

We also strip identifying details before the request leaves us where we can: the tutoring pipeline replaces your child’s name with a placeholder on the way out and puts it back in the reply, so the provider sees the math, not the child.

No. We do not sell or rent personal data, and we do not use student data for advertising or build advertising profiles. Mathmatix is paid for by subscriptions and school licenses — that is the whole business model.

• Your child.
• You, once your parent account is linked to theirs.
• Their teacher, if the account is part of a school class.

Nobody else, and not other students. Our own staff do not browse student conversations as a matter of course; when a staff account does need to view an account to resolve a problem, that access is read-only, expires automatically after 20 minutes, and is written to an audit log.

Parents can request the log of who accessed their child’s record from the parent dashboard.

When a school licenses Mathmatix, it is the school that decides which students have accounts, and rosters are usually synced from the school’s own system (such as Clever). Teachers see their own students; they do not see students in other classes.

For school-provided accounts, requests to see, correct or delete a student’s record normally go through the school, because the school is the one holding the education record. Contact us and we will work with them.

Not indefinitely. An automated sweep runs daily and deletes anything past its period. The two parents ask about most:

What	Deleted after
Uploaded photos and documents	30 days
Tutoring conversations (once the account has gone inactive)	1 year

Assessment results and graded work are kept for 3 years, the standard period for an educational record, so growth can be measured against a baseline. The full table, with every category and the reason we keep it, is in the Privacy Policy.

From your parent dashboard you can:

• Export everything we hold on your child, as a file.
• Delete your child’s account and its data.
• Correct something that is wrong, by filing an amendment request.

You can also withdraw consent for AI features at any time without deleting the account. If your child’s account came from their school, see the school question above. If you would rather not use a dashboard, contact us and we will handle it.

• Everything travels over HTTPS, and the site refuses plain HTTP.
• The most sensitive parts of a tutoring session — the summary of what a student struggled with — are encrypted at the field level in the database, so they are not readable from a database dump alone.
• Passwords are hashed, never stored in a form we could read.
• Uploaded photos are stripped of embedded location and camera metadata before anything else touches them.
• Sign-in is rate-limited against guessing, and every state-changing request carries an anti-forgery token.
• Logs redact secrets, and errors are monitored so problems surface quickly.

Yes. Mathmatix is built on large language models, and any product that tells you otherwise is overselling. It can misread a photo of handwriting, mis-state a rule, or follow a wrong turn confidently.

What we do about it:

• Where the math can be solved exactly, we solve it exactly rather than asking a model — a computed answer is not an opinion.
• Where it cannot, a second model from a different provider checks the answer. A model marking its own homework is not a check, which is why the checker is never the one that wrote the reply.
• When the two cannot agree, the answer is treated as unverified rather than stamped correct.

None of that makes it infallible. Encourage your child to say “I don’t think that’s right” — arguing with the tutor is good mathematics, and the tutor is built to take it well. For work that is being graded, their teacher is the authority, not us.

It is built not to. The tutor guides rather than answering: it asks what the first step should be, responds to what your child actually tried, and the verified answer to a problem is deliberately withheld from the tutor’s context unless your child has already attempted it.

A determined student can get an answer out of any AI tool, this one included. What we can promise is that the default behaviour teaches, and that you can see what happened in the session.

Contact us with the date and roughly what happened, and we will look at that session. If your child said something in a session that suggests they are struggling in a way that goes beyond math, tell us — and tell their teacher or school counselor, who can actually help.
