Terms

Halgo is operated by its founder as a sole trader. Contact for anything in this document, including notice under it: hello@halgo.app.

You must be old enough to enter a contract where you live, and you must be using Halgo for your own tutoring work or your school’s. Halgo has no accounts for students that a student creates for themselves; see the privacy notice for how a student or parent gets access.

You get a non-exclusive, non-transferable right to use Halgo for as long as your account is active. You may not resell it, rent access to it, or share your sign-in with someone who does not work for you.

You may not use Halgo to break the law, to process data you have no right to process, or to attack it — automated scraping, deliberately overwhelming it, or trying to reach another tutor’s data.

The records you put into Halgo about your students belong to you. Halgo processes them on your instructions and does not sell them, rent them, or use them to advertise anything.

Under data protection law you are the controller of your students’ personal data and Halgo is your processor. That means you decide what to collect and why, and you are the one a parent or a regulator asks. What Halgo does and does not do in that role is set out in the data processing terms, which form part of this agreement.

Two consequences worth stating plainly, because they are the ones tutors get wrong. First: it is your responsibility to have a lawful basis for the records you keep about a child, including a parent’s permission where your local law requires one — Halgo does not check this and cannot. Second: Halgo never contacts your students on its own initiative, so anything a student or parent receives from Halgo is something you switched on.

You keep ownership of the textbooks, worksheets, notes and files you upload. You give Halgo permission to store them, process them, and send the parts needed to the AI providers listed in the privacy notice, for the sole purpose of producing your material.

You confirm you are allowed to upload what you upload. Most textbooks are copyrighted; using a copy you own for your own teaching is normally fine, and redistributing extracted exercises to the world is normally not. Halgo does not check, and cannot advise you on it.

Content that Halgo generates from your material — exercises, homework sheets, cards, summaries — is yours to use. It is generated by language models and may be wrong; the section below says what that means.

Halgo uses language models to read textbooks, write exercises, grade answers and summarise lessons. Model output is not checked by a person before you see it. It can misread a page, invent an exercise that does not appear in your book, mark a correct answer wrong, or produce text in the wrong register for a child.

You are the teacher. Review what Halgo produces before you put it in front of a student. Halgo is a drafting tool, not a colleague who takes responsibility for the lesson.

The free plan allows up to 3 students and 1 textbook. Solo allows up to 15 students and 5 textbooks. Pro has no cap on either. These are enforced by the product and the numbers on the site come from the same table the server checks against.

During the closed beta nobody is charged and there is no way to pay from inside the product. If that changes, you will be told before it applies to you, and no payment is ever taken without you entering card details yourself.

Halgo also meters how much AI work an account may do in a month. If you reach that limit, generation stops and says so; nothing is deleted and nothing is billed.

Access to Halgo is granted deliberately, one account at a time, while the beta lasts. Signing in is not the same as being admitted: an account that has not been granted access can sign in and will be told it has none.

Halgo may suspend or end your access if you break these terms, if you use the product in a way that endangers other tutors’ data or the service itself, or if the beta ends. Where the reason is not urgent you will get reasonable notice by email.

You may stop at any time. Before you go, export what you want to keep — every student’s data can be exported from their page in the product. Ask at hello@halgo.app and your account and its data will be removed; there is no self-service “delete my whole account” button yet, and pretending otherwise would be the sort of promise this document is trying to avoid.

Halgo is early software running for a handful of tutors. Concretely:

• There is no uptime commitment and no support-response time.
• Features can change or be withdrawn, sometimes without notice.
• Data loss is unlikely but possible. Backups are taken by the hosting provider on its own schedule; Halgo does not operate a restore process with a stated recovery time.
• Some things the interface offers are still being built, and are labelled where they are.

If your teaching cannot survive Halgo being unavailable for a day, keep your own copy of what matters.

Halgo is provided as it is. To the extent the law allows, Halgo is not liable for lost teaching time, lost income, lost data, or anything a model got wrong that you passed on to a student without checking.

Nothing here limits liability that cannot be limited — including for death or personal injury caused by negligence, for fraud, or for anything else your local consumer or data protection law reserves. Where you are a consumer, your statutory rights are unaffected.

Where liability can be limited and Halgo is liable anyway, that liability is capped at what you paid Halgo in the twelve months before the claim — which, during the beta, is nothing.

When these terms change, the date at the top of this page changes with them. For a change that materially affects you, you will be emailed at the address on your account before it takes effect. Continuing to use Halgo after that is acceptance; if you do not accept, stop using it and ask for your data back.

These terms are governed by the law of Slovenia, and the courts of Slovenia have jurisdiction. If you are a consumer, this does not take away the protection of the mandatory law of the country you live in, nor your right to bring a claim there.
