The agreement between you and AG Performance for coaching, blocks, camps and retreats.
Version 2.0 · In force from 6 October 2026 · Swiss law, Zurich jurisdiction
These terms govern every coaching service provided by Alexander Grabher Performance (trading as AG Performance), a sole proprietorship registered in Switzerland (UID CHE-352.501.392), Buchholzstrasse 13, 8053 Zurich (“we”, “us”). They apply to private lessons, group training, season blocks, camps and retreats, whether booked through this website, the coaching app, by email or in person.
If the business changes form. We intend to transfer the business to a Swiss limited company (GmbH). If that happens, your agreement transfers with it on unchanged terms, and we will tell you before it takes effect. Nothing you have already paid for is affected.
Groups are formed by us according to level and age. We may move a player between groups where that serves the training, after speaking to the player or their parent.
Sending a form or an enquiry is not yet a contract. The contract comes into existence when we confirm your place in writing — by email or in the app. For camps and retreats, the place is secured only once payment has been received.
Published prices are in Swiss francs and are the amounts you pay. We are not currently registered for Swiss VAT (MWST), so no VAT is charged or shown. Should we become liable to register, we will tell you before any VAT is added to future invoices; it will not be charged retrospectively.
Blocks, camps and retreats are payable in advance. Single hours are invoiced monthly in arrears unless agreed otherwise. Invoices are due within ten days of the invoice date.
You may pay by bank transfer to the account on the invoice, or by card or TWINT through Stripe. Card details are handled by Stripe and never reach us.
If an invoice is not paid when due, we may suspend further sessions until it is settled. Default interest of 5% per annum applies from the due date (Art. 104 Swiss Code of Obligations).
Move or cancel a session free of charge up to 24 hours before it starts. Inside 24 hours the session is charged in full, because the court and the coaching hour are already committed and cannot be resold at that notice.
If we cancel — illness, injury, or anything else on our side — you are not charged, and we offer you a replacement slot or credit the hour back to your block.
Full refund up to seven days before the camp starts. Within seven days the fee is not refundable, but the place may be transferred to another player of a suitable level.
Retreats carry their own cancellation schedule, set out in the booking confirmation for that retreat, because we commit to hotels and courts long in advance. Those terms prevail over this section.
If illness or injury stops you training for four consecutive weeks or more, send us a medical certificate and we will credit the unused hours to the following season at no charge.
Outdoor sessions cancelled for weather are moved, not charged. Where a camp specifies an indoor fallback venue, the week runs in that venue and no refund arises for weather.
You confirm that you are fit to take part in physical training, and that you have told us about any injury, illness, medication or condition that could affect you on court. If something changes, tell us before the next session.
Coaching is not medical treatment and we are not doctors. Nothing we provide — training plans, screening results, recovery advice — is a diagnosis or a substitute for medical advice. If you have any doubt about your health, see a doctor before you start.
You take part at your own risk. Sport carries a risk of injury that no amount of good coaching removes.
You are responsible for your own insurance. Accident and health insurance is compulsory in Switzerland and we do not provide it. We strongly recommend personal liability insurance as well. We do not insure players against injury, illness or loss of personal property.
A player under 18 is booked by a parent or legal guardian, who agrees to these terms on their behalf and is liable for payment. Parents are responsible for bringing and collecting children, and for telling us about any medical condition, allergy or medication.
We may end a child’s participation, without refund for the remainder, if their behaviour endangers themselves or others after we have raised it with the parent.
We sometimes take photographs or video at camps and retreats, and use video in coaching to analyse technique. We will not publish any image of you without your separate written consent, and for a child, the consent of a parent. You may refuse, or withdraw consent later, and we will stop using the image going forward — neither affects your training in any way.
We are liable for damage we cause intentionally or through gross negligence, and for injury to life, body or health, without limit. For everything else, our liability is limited to the amount you paid us for the service concerned. We are not liable for indirect or consequential loss, nor for loss of property left at a venue.
Nothing in these terms limits any liability that Swiss law does not allow to be limited.
If a service cannot be delivered because of something neither side controls — a venue closing, official restrictions, extreme weather, illness in the coaching team — we will offer a replacement date or credit. Where a retreat or camp cannot run at all, we refund what we have not irrecoverably committed to third parties, and we will show you what that was.
We may change these terms for future bookings. The version in force when you book is the one that applies to that booking. Material changes affecting an ongoing block or season will be sent to you by email at least 30 days before they take effect, and you may cancel the remainder of that block for a pro-rata refund if you do not accept them.
These terms are governed by Swiss law, excluding its conflict-of-law rules and the United Nations Convention on Contracts for the International Sale of Goods. The place of jurisdiction is Zurich, Switzerland. Where you deal with us as a consumer, this does not remove any protection given to you by the mandatory law of your country of residence.
If any provision is found invalid, the rest remains in force.
