Terms of service

Who we are

Kratos Natural is a trading name of Liam "Kratos" Krassenburg, a sole trader at Clausstraat 6, 2661 BZ Bergschenhoek, Netherlands. KVK 92192475, VAT NL004942521B32, info@kratosnatural.com.

These terms cover the use of kratosnatural.com and kratosnatural.nl, and everything you buy or download there. Using the site means you accept them.

Which language version applies

These terms exist in English and in Dutch. Each one is written in its own language rather than translated out of the other, so that both say the same thing to the person reading it.

If the two versions are ever found to differ on something that matters, we apply whichever reading is better for you as a consumer. Holding somebody to a version they cannot read is not what a second version is for.

What we offer

Coaching. The Kratos Protocol: twelve weeks, one to one, by video call and messaging. A baseline measurement and a full lifestyle analysis, a personal plan, weekly conversations and daily contact by message.

Physical products, shipped within the Netherlands.

Research articles. Our own analyses of published research, with the sources named, including the studies that found nothing. Free, and no account needed.

Guides and e-books. The applied protocols built on that research. Free, permanently, no account, no email address, no sample chapter.

A newsletter you sign up for yourself, and can leave from every email we send.

Free means free

Our guides, e-books and research articles cost nothing and that stays true. There is no paywall behind them, no email address needed, no account. That is a promise rather than an offer, and we cannot withdraw it retroactively for anything you have already downloaded.

You may read them, keep them, print them and pass them to anyone you like. You may not sell them, present them as your own work, or build them into something you charge for.

Ordering and paying

An agreement exists once we have confirmed your order.

Prices on the site are in euros and include VAT. The price you see at checkout is the price you pay, and shipping costs are listed separately there before you confirm.

Payments run through Stripe. We see whether a payment succeeded and which email address is attached to it. Your full card details never reach us and we do not store them.

We may refuse an order, for instance on an obvious pricing error or when we cannot deliver. If that happens after payment, you get the full amount back.

Buying coaching

The agreement exists once we confirm your purchase. The price is shown at checkout, and so is whether VAT is included.

Places are limited. We may refuse a purchase, including when we think the protocol does not suit you. If that happens after payment, you get everything back.

At the intake we write down three goals together: one you feel, one you measure, one you see. The guarantee is measured against those. What is not written down does not count, in either direction.

Your fourteen days

As a consumer you have fourteen days to withdraw, on physical products and on coaching.

For products that period starts on the day you receive the product. For coaching it starts on the day the agreement is concluded.

Twelve weeks does not fit inside fourteen days. So at checkout we ask you to tick that the protocol may start straight away, and the button does not work without it. Ticking it does not take your fourteen days away. It changes only what withdrawing costs, from everything back to a proportionate amount for what has already been delivered. See our refund policy.

Free downloads carry no withdrawal period, because there is no paid agreement underneath them.

The results guarantee

If at week twelve you have reached fewer than two of the three goals, having done what you agreed to do, we keep working with you at no cost for up to twelve more weeks. If the goals are still not reached after that, you get the full amount back.

What "done what you agreed to do" means is set out in the coaching agreement you sign at the intake. It comes down to this: turn up to every conversation, follow the plan, and say so at the check in when a week did not work. Those conditions exist to tell a plan that did not work apart from a plan that was not followed. It is not a list of ways to lose the guarantee.

This guarantee sits on top of your rights under the law and does not limit them.

Coaching is not healthcare

We are not a doctor, dietitian, psychologist or physiotherapist, and we are not BIG registered. Nothing in the protocol is diagnosed, treated, cured or prevented.

If you have a diagnosed condition, pain, are pregnant, take medication, or things are not going well mentally, see a qualified professional first. Coaching runs alongside good healthcare, never instead of it.

Blood values are drawn on your instruction and read by your own doctor. We use the difference between the start and the end as a measurement and diagnose nothing with it. Anything outside the reference range goes to that doctor.

If something you raise belongs with a doctor or a therapist, we say so and refer you on. Either of us may end the agreement at that point, and we refund what has not been delivered.

Delivery

See our shipping policy. We deliver within thirty days in any case, and if we cannot, you may cancel at no cost.

Not medical advice

This is the most important clause on this page.

Everything we publish and sell is meant to optimise a healthy body. It is not medical advice. We diagnose nothing and treat nobody. We are not a doctor, dietitian or physiotherapist.

Talk to your doctor or another qualified professional first, and certainly if you have a diagnosed condition, are in pain, are pregnant or take medication. Where a guide reaches the edge of what it can responsibly say, it says so and points you on.

Our products are not intended to diagnose, treat, cure or prevent any disease.

What we promise and what we do not

We stand behind what we write and trace every claim back to a published source. What we do not promise is a result. What works for one person does not work for the next, and most studies measure averages across groups rather than individuals.

We are not liable for damage arising from following information on this site, except where we acted deliberately or with gross negligence, and except where the law does not allow liability to be limited. For consumers we expressly leave untouched the statutory liability for death, injury and product liability.

Your account

You sign in with a link we send to your email address. A password is allowed but never required, because that link keeps working. We keep no customer database: your orders are fetched from Stripe live, at the moment you open the page.

Keep access to your mailbox to yourself. Whoever reaches your email reaches your order history.

You sign up yourself. The unsubscribe link sits at the foot of every email and works immediately.

Changes

We may change these terms. The version that applies to an order is the one that stood on the site when the order was placed. The date below says when we last changed anything.

Governing law

Dutch law. If you are a consumer, you keep the protection of the mandatory law of the country you live in. Disputes go to the competent Dutch court, after we have first tried to settle them by email.
