Terms of service

Who you are agreeing with

Memoza is operated from the Netherlands. The identifying details of the operator belong on the imprint, and they are not on record here yet.

What Memoza is

Memoza serves practice questions for specific university courses, grades your answers, and keeps a per-concept mastery estimate that decides what you are asked next. Questions come from course packages that are validated before they are published — nothing is invented while you answer.

Calculations and algebraic answers are checked deterministically by a computer-algebra system. An AI model is used in two places only: written proofs in mathematics and written clinical reasoning in medicine, where it judges which steps of the marking rubric your work evidences. Every grade records which grader produced it. The privacy notice describes this in full, including exactly where that is shown to you on which screen.

Memoza is in beta, and nothing is for sale

Everything in the product today is free. There is no checkout anywhere on this site, no payment is taken, and nothing you do here creates a payment obligation.

No prices are published on this site. There is no price list, and the subscription section below is a draft describing how a paid plan is intended to work; it is not a term you are agreeing to, and nothing in it is an offer, because the terms that would carry one are the ones missing below.

The subscription (draft, not yet in force)

What is sold. One subscription that unlocks every premium feature at once, billed monthly or yearly as you choose: scanning handwritten work, the study planner and readiness view, mock exams, premium explanations, advanced analytics and practising in more than one course. There are no separate passes per course. Grading itself, the review of your own mistakes, objecting to a grade, the privacy and erasure paths and deterministic feedback stay free for everyone, subscriber or not.

Price and payment. The price is shown on the checkout page before you confirm; it includes Dutch VAT. Payment is taken in advance for one whole period at a time — a month on the monthly plan, a year on the yearly one — through Stripe, our payment processor, by iDEAL | Wero or card; Memoza never sees or stores your bank or card details. Paying by iDEAL | Wero also authorises a SEPA Direct Debit mandate, because iDEAL | Wero is a single payment rather than a standing one: each renewal is then collected from the same bank account by direct debit. Your subscription becomes active when the first payment has succeeded, not when the checkout page has been shown.

Renewal and cancellation. The subscription renews automatically at the end of each period — every month on the monthly plan, every year on the yearly one — and is charged in advance. You can cancel at any time from your account; cancelling stops the next charge, and access runs to the end of the period already paid for. Nothing is refunded for the remainder of a period you have paid for, except where the law gives you a refund right. You can move from the monthly plan to the yearly one from your account: the month you have paid for runs out first, the year begins the day it ends, and that is the day you are charged for it — nothing is charged in advance of that day and nothing is prorated. A booked change can be cancelled at any time before it starts. Moving from the yearly plan to the monthly one is done by cancelling: your access runs to the end of the year you paid for, and you can subscribe monthly after that.

Your right of withdrawal. As a consumer in the EU you may withdraw from the subscription within fourteen days of the first payment without giving a reason, by writing to [email protected]. Because the service starts immediately, you will be asked at checkout to expressly request that start and to acknowledge that, once you have used the service, a withdrawal refunds the part of the first period you have not used rather than the whole of it.

Failed payments. If a renewal payment fails, Stripe retries it; while it is unpaid the premium features are paused, and the subscription ends if payment has not succeeded within the retry period. Nothing you created is deleted because a payment failed.

Price changes. A change in the price of your plan is announced by email to the address on your account at least thirty days before it applies to you, and you can cancel before then at no cost.

Trial. A free trial period may be offered before the first payment. Whether one applies, and how long it lasts, is stated on the checkout page; a trial ends without charge unless you have confirmed a paid subscription.

Accounts

You can practise without an account; doing so creates a guest record with no name and no email. If you do create an account you give an email address and a password, and keeping that password to yourself is your responsibility. On a shared computer, sign out rather than closing the tab — signing out is what ends the session.

There is no self-service password reset. If you lose your password, write to [email protected] and a person verifies you and resets it by hand.

What your mastery score is, and is not

Your mastery score is an adaptive learning estimate. Its only job is to decide what you practise next. It is never an official academic judgement and it is not evidence of competence.

Formal academic use of Memoza results — for grades, credit, admission, or progression — is not permitted until that use has been separately assessed. This is the clause the privacy notice refers to.

Course content and the work you submit

Course packages are written or generated by Memoza and its contributors and are published under a version, so the questions you see can be traced to the package they came from.

The answers you submit are stored as an append-only record: your mastery estimate is rebuilt by replaying your whole attempt history, so an attempt is never silently edited. Deleting your data removes the record rather than rewriting it.

Availability, liability and the law that applies

Memoza is a beta. Features can change or be withdrawn while it runs, and this section is where a document would normally say what that means for you. It does not say it yet.

Changes

This page is dated. When written terms replace this shell that will be a visible change here, not a silent edit.
