Terms of Service
Version 2 · Gældende fra 21. september 2026
På denne side
These terms are the agreement between you and CS Konstruktions-Planung OÜ, Viru väljak 2, Kesklinna linnaosa, 10111 Tallinn, Estonia, registered under 17452901, VAT EE102970135. You can reach us at legal@ollinter.com.
They cover using Ollinter: finding a professional, booking a session, paying for it, and what happens when something goes wrong. Professionals have their own agreement with us on top of these terms, in the professional agreement, and the day-to-day money rules are in the booking and money rules.
By creating an account or using the platform you accept these terms.
What Ollinter is
Ollinter is a marketplace. Independent professionals offer their time here, and you book it. We run the place: the listings, the scheduling, the room the session happens in, the messages, the payments and the records.
We do not give the lesson. The professional does, and the contract for it is between you and them. We do not promise that you will pass an exam, learn a language, win a client or reach any other result, because that is not ours to promise.
What we do promise is the part we run: the professional was who they said they were when we checked, the money is held until the session has happened, and there is somewhere to go when it does not.
Who can use it
You must be 18 or older. We ask your date of birth once and we hold the account if the answer says otherwise.
Your details must be true and kept up to date. Your account is yours alone: do not share it, sell it or let somebody else use it.
We can refuse, limit or close an account for a good reason, such as false details, fraud, misuse of the booking or payment system, repeated breaches of these terms, or behaviour that harms other people here. When we do, we tell you why and you can appeal, unless the law stops us from saying.
Booking and paying
The price you see is the price you pay. The professional sets what they want to receive and our share is added on top, so nothing appears at checkout that was not on the page before it.
A booking is made when your payment succeeds. Until then the time is held for you, not booked, and the hold runs out if the payment does not complete. You can hold a few bookings at once; if you keep leaving holds to expire, we make you wait a little before the next one.
You cannot book your own listing.
A one-to-one lesson is 50 minutes and a trial is 25. Group classes and lectures say their own length on the page.
Your money is held until the session has happened, and released to the professional after the dispute window has passed. The window is shown on the booking. Until then it is neither theirs nor ours.
Trial sessions
Many professionals offer a cheaper first session. A trial is for your first booking with that professional, and there is a limit on how many trials one person can take across the platform. Where several accounts start trials from one device or one network in a short time, we stop taking more from there.
Cancelling and rescheduling
Cancel early and you get your money back in full. The deadline is shown before you book and on the booking itself.
Cancel after the deadline and the session is charged in full, because the professional held that time for you and turned other work away.
You can move a booking to another time with the same professional, twice. Moving it is not a way around the deadline: once the deadline has passed, the booking can no longer be moved, only cancelled under the rule above.
Free cancellation is not unlimited. Cancel three paid bookings within 30 days and your free window closes for the next 30 days. During that time every cancellation is charged in full, however early you make it. No extra fee is ever charged. We tell you before you use the last free one, when the window closes, and when it opens again.
When a session does not happen
- The professional does not turn up. Your money comes back automatically. You do not have to ask.
- You do not turn up. The professional is paid. They held the time.
- Neither of you could join because something on our side failed. Your money comes back.
Sometimes an automatic refund waits up to three days so a person can look at it first. It is not a refusal, and unless we tell you otherwise the refund is paid.
If something went wrong
If the rules above do not settle it, open a dispute from the booking. You have 72 hours after the session was due to end.
A person reads it. We look at what both sides say and at what the platform recorded, and we answer within a few working days. Our decision is an internal one. It does not take away any right you have in law, and it does not make us a party to the contract between you and the professional.
Where somebody disputes far more often than is usual, we stop paying their automatic refunds straight away and have a person look at each one first.
Recordings
A session is not recorded unless everyone in the room agrees first. You are asked before you join, separately for recording, for a written transcript, for translated captions and for AI help with them. One refusal is enough to keep a feature off for that room, except in a lecture, where the audience is not on stage and the rule covers the people speaking.
You can withdraw your answer at any point up to the end of the session. Withdrawing the transcript deletes it at once. Withdrawing the recording stops it there; what was already recorded is deleted on the ordinary schedule.
What we keep and for how long is in the privacy policy.
What you must not do
- Give false, misleading or fraudulent information.
- Misuse the booking, payment or dispute system.
- Arrange or pay for sessions outside the platform to avoid our fees.
- Pretend to be somebody else.
- Offer or ask for anything unlawful.
- Harass, threaten or discriminate against anyone.
- Break into, overload or interfere with the platform.
What happens if you break the rules
Depending on what happened, we may cancel bookings and refund them, limit what your account can do, suspend it, or close it. While an account is suspended we do not send payouts from it: the earnings stay the professional's and go out on the first run after the suspension is lifted.
We tell you what we decided and why, and you can appeal, unless naming the reason would break the law. A listing paused for missed sessions is a separate and smaller thing: it hides the listing for a while and touches no money.
Your words and ours
What you write stays yours. By putting it here you let us store it, translate it, show it where it belongs on the platform and keep it in the records, for as long as we run the service.
The platform itself, its software, its design and its name are ours. Do not copy or sell them.
If you upload something, it must be yours to upload.
Availability
We keep the platform running as well as we can, and we cannot promise it never breaks. Maintenance, failures, attacks and the failures of companies we depend on all happen. If a technical failure ruins a session you paid for, the refund rules above apply.
Our responsibility
We are responsible for the part we run, and for what the law makes us responsible for whatever we write here.
We are not responsible for the lesson itself: what was taught, how well, whether it was worth it, or what the professional said or did. That sits with them. Nor are we responsible for what one user says about another, or for a loss that follows from information somebody else gave you.
Nothing here limits our responsibility for death or personal injury caused by our own negligence, for fraud, or for anything else the law says cannot be limited. If you are a consumer, the protections your own country gives you apply whatever these terms say.
Your right to change your mind
If you are a consumer in the EU, the law gives you 14 days to withdraw from a contract made at a distance. For the platform itself there is nothing to withdraw from: your account is free.
For a session, the cancellation rules above are what you use, and up to the deadline they give you your money back in full. Where a session is booked to happen inside those 14 days, the professional starts performing at your request, and once the session has been given there is nothing left to withdraw from.
Closing your account
You can close your account from your settings, at any time, without asking us. What happens to your data is in the privacy policy.
Closing an account does not undo what already happened: bookings that were paid for, money that moved, and records the law makes us keep.
Changes to these terms
We can change these terms when there is a good reason, such as a change in the law, a change to the platform, a new feature, or a measure against fraud.
The current version is always on the platform. When a change matters to you we tell you before it takes effect, and where the law requires it you can accept it, refuse it, or stop using the affected service. Changes do not apply backwards to bookings already made.
Law, and where to complain
These terms are governed by Estonian law. If you are a consumer, this does not take away the protections of the law where you live.
Complain to us first, at legal@ollinter.com: it is the fastest way to fix something. If we cannot agree, you keep every right you have to go to the courts or to the authorities of your own country.
