Terms of Use

Last updated: 27 August 2026

1. Who we are

Win Within is operated by Lycaste Ltd, Business ID (Y-tunnus) 2638862-1, registered in Finland, address Rantapolku 15, 00330 Helsinki ("Win Within", "we", "us", "our").

Contact: hello@byakku.com

These Terms of Use ("Terms") govern your access to and use of the Win Within app, website, digital audio practices, live sessions, courses, downloadable materials and any related services (together, the "Service").

By purchasing, accessing or using the Service, you confirm that you have read, understood and accepted these Terms. If you do not accept them, please do not use the Service.

Where you purchase live mentoring, a squad or academy programme, or any bespoke service, a separate written agreement may apply. Where that agreement conflicts with these Terms, the separate agreement prevails for that service.

2. Who may use Win Within

You must be at least 18 years old to purchase the Service and to enter into an agreement with us.

Win Within content may be suitable for younger athletes, but a person under 18 may use the Service only where:

a) a parent or legal guardian has purchased the access and holds the account; b) that parent or guardian has read and accepted these Terms on the minor's behalf; and c) the parent or guardian has confirmed that the minor has no health condition that would make the practices unsuitable, consulting a doctor where appropriate.

The parent or guardian remains responsible for the minor's use of the Service and for supervising practice where supervision is appropriate.

Where the Service is purchased by an academy, club, federation or other organisation for its players, staff or members, separate written terms apply. The purchasing organisation is responsible for ensuring that each participant has been informed of the health and safety provisions in Section 4 and, where a participant is under 18, that written parental consent has been obtained and can be produced on request.

3. What Win Within is — and what it is not

Win Within provides educational and self-development content: guided breathing practices, relaxation and recovery practices, meditation, visualisation, gentle movement and yoga practice, reflection prompts and written material relating to attention, presence and performance.

Win Within is not, and does not present itself as:

  • medical care, diagnosis or treatment;

  • psychotherapy, psychiatric care or clinical psychological treatment;

  • physiotherapy, rehabilitation, or sports medicine;

  • nutritional, pharmaceutical or any other form of regulated healthcare advice;

  • a medical device, or health care within the meaning of any applicable regulation;

  • a substitute for care from a licensed healthcare professional.

No doctor–patient, therapist–client or other regulated professional relationship is created between you and Win Within, or between you and any instructor, through your use of the Service.

Our practitioners hold professional qualifications in their own fields, including yoga (E-RYT 500) and therapeutic modalities. Our practitioners are not licensed medical doctors, psychiatrists, clinical psychologists or physiotherapists, and nothing in the Service constitutes the diagnosis or treatment of any medical or psychological condition. Where a practice or conversation touches on emotional or psychological material, this is offered as education and reflection — not as clinical care.

4. Health, safety and your wellbeing

We take the safety of these practices seriously. This section is the most important part of these Terms — please read it in full.

4.1 Consult your doctor first

Speak with your doctor or another qualified healthcare professional before beginning any practice in the Service if any of the following apply to you:

  • you have a diagnosed illness or medical condition of any kind;

  • you are taking prescription medication;

  • you are pregnant, may be pregnant, or have recently given birth;

  • you are recovering from surgery, injury or illness;

  • you are under the care of a healthcare professional for any physical or psychological condition;

  • you are uncertain, for any reason, whether these practices are appropriate for you.

If your healthcare professional advises against these practices, or advises modification, follow their guidance rather than ours.

4.2 Conditions requiring particular caution

Breathing practices affect the nervous system and the body's physiology. Certain practices — in particular those that lengthen, deepen, retain or intensify the breath — may be unsuitable for people with the following, and must not be undertaken without medical clearance:

  • epilepsy or any seizure disorder;

  • cardiovascular conditions, including high or unstable blood pressure, heart disease, or a history of heart attack or stroke;

  • aneurysm, or a family history of aneurysm;

  • respiratory conditions including asthma or COPD;

  • glaucoma or retinal detachment;

  • pregnancy;

  • diabetes;

  • recent surgery, or any acute injury;

  • osteoporosis;

  • psychiatric conditions, including psychosis, bipolar disorder, schizophrenia, severe anxiety disorder, PTSD or dissociative disorders;

  • current or recent substance dependency.

This list is illustrative, not exhaustive. If your condition is not named here, that does not mean the practices are safe for you — please ask your doctor.

4.3 How to practise safely

You agree to follow these rules whenever you use the Service:

  • Never practise while driving, cycling, operating machinery, or doing anything else that requires your attention.

  • Never practise in or near water — including swimming pools, baths, lakes, the sea, ice baths or cold plunges. Breath practices can cause fainting; fainting in water can be fatal.

  • Practise seated or lying down, on a stable surface, where a loss of balance or consciousness would not cause injury.

  • Practise on an empty or light stomach.

  • Do not force, strain or push beyond comfort. These practices are not endurance tests.

  • Stop immediately if you experience dizziness, light-headedness, tingling, cramping, chest pain, shortness of breath, nausea, visual disturbance, or any pain or distress. Return to normal, natural breathing and rest.

  • Seek medical attention if symptoms persist.

4.4 Emotional and psychological responses

Practices involving breath, stillness, relaxation and visualisation can bring emotional material to the surface. This is a normal and generally healthy part of the work. However, if you find that a practice consistently increases distress, agitation, intrusive thoughts, flashbacks or dissociation, stop the practice and speak with a qualified mental health professional.

The Service is not designed for, and must not be used as, treatment for trauma, acute psychological distress or any psychiatric condition.

4.5 If you are already under professional care

If you are currently under the care of a doctor, psychiatrist, psychologist, sport psychologist, physiotherapist or any other healthcare professional, you agree to inform that professional that you are taking part in these practices, and to follow their guidance where it differs from ours.

This matters particularly for athletes working within a team or federation medical structure. We are one input among several. Your treating professionals hold the fuller picture, and their judgement takes precedence over anything in the Service.

4.6 In an emergency

The Service is not monitored and cannot respond to emergencies. If you are in crisis, or if you are having thoughts of harming yourself or another person, contact emergency services immediately (112 in Finland and across the EU, or your local emergency number) or go to your nearest emergency department.

4.7 Your ongoing responsibility

You are responsible for deciding whether any practice is appropriate for you on any given day, and for adjusting or stopping it. You know your body and your circumstances; we cannot see you, assess you or supervise you. By using the Service you confirm that you are voluntarily taking part, that you accept the risks inherent in physical and contemplative practice, and that you take responsibility for your own safety and wellbeing while practising.

4.8 Accuracy of what you tell us

Where you complete a health questionnaire, intake form or screening before working with us, you agree to answer accurately and completely, and to tell us promptly if your health circumstances change. Our ability to adapt a practice safely depends entirely on the accuracy of what you share. We are not responsible for consequences arising from information that was incomplete or inaccurate.

4.9 Movement and physical practice

Where the Service includes yoga, stretching, mobility or any other physical movement content, the following applies in addition to everything above.

Your physical readiness. By taking part in movement content, you confirm that you are in adequate physical health to do so, and that you have no injury, disability or condition that would make the movement unsafe for you.

Consult a professional first. You should consult a doctor, physiotherapist or other qualified professional before beginning or modifying any movement practice — particularly if you have a current or previous injury, a history of heart disease or high blood pressure, a chronic condition, joint instability or hypermobility, a spinal condition, osteoporosis, or if you are pregnant or recently postpartum. We are expressly advising you here of the necessity of doing so.

Athletes in rehabilitation. If you are currently rehabilitating an injury under the guidance of a physiotherapist, athletic trainer, doctor or team medical staff, do not add movement content from the Service without their approval. Their programme takes precedence over ours.

Young athletes. Growing bodies carry particular considerations, including in the spine and shoulders. Where a participant is under 18, a parent or guardian is responsible for ensuring the movement content is appropriate, and for consulting the young person's coach, physiotherapist or doctor where any doubt exists.

We cannot see you. This is the central limitation of any recorded or online movement practice. We cannot observe your alignment, correct your position, spot compensation patterns, or adapt a shape to your body in the moment. What is safe for one body may not be safe for yours. You are therefore responsible for working within your own range, and for treating every instruction as an invitation rather than an obligation.

4.10 How to practise movement safely

  • Practise on a stable, non-slip surface with clear space around you, free of furniture, walls and hazards.

  • Wear clothing that allows free movement, and use props (a mat, blanket, block, cushion, chair) where suggested.

  • Warm up as instructed and do not skip preparatory movements.

  • Move within a comfortable range at all times. Never force, bounce, or push into a position. Sensation is acceptable; pain is not.

  • Skip or modify any movement freely. Choosing not to do something is always a valid option and is never a failure of the practice.

  • Stop immediately and rest if you feel sharp pain, joint pain, dizziness, numbness, tingling, breathlessness or nausea. Seek medical attention if symptoms continue.

  • Do not attempt movement content while fatigued to the point of poor control, immediately after intense training or competition, or under the influence of alcohol or any substance affecting balance or judgement.

  • Keep water nearby and stop if you feel overheated.

5. No guarantee of results

Win Within offers practices and education. It does not offer outcomes.

Individual results depend on factors entirely outside our control — including your consistency, your circumstances, your physiology, your history, your coaching environment and your competitive context. Accordingly:

  • We make no guarantee, warranty or representation of any specific result, improvement, performance outcome, competitive result, ranking, health benefit, emotional state or commercial benefit.

  • Any examples, testimonials, case descriptions or results described anywhere in our materials are illustrative of what some individuals have experienced. They are not typical, average or promised results, and they are not a projection or guarantee of what you will experience.

  • Nothing in our marketing, sales pages, emails, social media or app content should be read as a promise of results.

6. Insurance and personal responsibility

We do not provide health, accident, travel or life insurance cover for participants in any part of the Service, whether online or in person.

You are solely responsible for holding appropriate insurance for yourself, and for the cost of any medical or hospital care, emergency transport, or treatment you may require in connection with your participation. Where you take part in an in-person event, retreat or onsite programme, you are responsible for your own travel and health insurance for the duration.

7. Live sessions, recordings and confidentiality

This section applies where you take part in live online or in-person sessions, whether one-to-one, in a squad, or in a group programme.

Recording by us. Live sessions may be recorded so that participants can revisit the material. Where a session is recorded, we will tell you before recording begins. By taking part in a recorded session, you consent to your voice, image, name and contributions being captured in that recording, and to the recording being made available to the participants of that programme for the duration of their access

We will not use recordings of you for marketing, promotion or public distribution without your separate, specific written permission. If you would prefer not to appear in a recording, tell us and we will arrange your participation accordingly — with your camera and microphone off, or by providing you the recording without your participation included.

Recording by you. You may not record, screen-capture, transcribe or otherwise reproduce any live session, in whole or in part, without our prior written consent. This protects both our material and the privacy of other participants.

Confidentiality between participants. In any group, squad or cohort setting, what other participants share is theirs. You agree to keep it confidential and not to repeat, publish or discuss it outside the group. This is a condition of participation. We may remove a participant who breaches it, without refund.

Testimonials. If you give us a testimonial, review or written feedback, you grant us permission to publish it, in whole or in edited form, using your first name, last initial and — where relevant to the context — your sport, role or country. You may withdraw that permission at any time by emailing us, and we will remove it from materials we control going forward.

8. Your account and access

You receive a personal, non-transferable right to access the Service using the credentials issued to you. You agree to:

  • provide accurate information at purchase and keep it current;

  • keep your login credentials confidential;

  • not share, resell, lend or transfer your access;

  • notify us promptly at hello@byakku.com if you believe your account has been accessed by someone else.

One purchase covers one individual user, unless you have bought a multi-user, squad, academy or organisational licence. Access shared beyond the scope of the licence purchased may be suspended without refund.

9. Prices, payment and taxe

Prices are shown at the point of purchase and are stated in euros (EUR) unless otherwise indicated. Prices include Finnish VAT where applicable; for customers outside Finland, the applicable VAT or sales tax is determined by your location and shown at checkout.

Payments are processed by our third-party payment providers. We do not receive or store your full payment card details.

We reserve the right to change prices at any time. Price changes do not affect purchases already completed.

10. Cancellation and refunds

10.1 Your 14-day cancellation right

Under EU and Finnish consumer law, you have the right to withdraw from a distance purchase within 14 days, without giving a reason.

We do not ask you to waive this right. It applies to your purchase of digital content from us in full.

To cancel, email hello@byakku.com within 14 days of purchase. We will refund the amount you paid within 14 days of receiving your notice, using the same payment method you used. You do not need to explain why.

10.2 Our guarantee

Put simply: if Win Within is not right for you, tell us within 14 days and we will refund you in full.

10.3 Live programmes and mentoring

Where you have booked a live programme, squad place or mentoring container, sessions missed or unused are not refundable, and the fee is payable in full once the programme has begun. Rescheduling is possible where we are given reasonable notice and where the schedule allows.

10.4 Statutory rights are unaffected

Nothing in this section limits your mandatory rights as a consumer under the law of your country of residence.

11. Intellectual property and trademarks

All content in the Service — audio recordings, video, text, frameworks, module structures, practice names, reflection prompts, images, design and method architecture — is owned by us or licensed to us, and is protected by copyright and other intellectual property law.

Win Within, The Inner Court, The Invisible Game, The Inner Warm Up, and the module framework Release · Recover · Refocus · Rise are our trademarks, whether registered or unregistered. Nothing in these Terms grants you any right to use them.

You receive a limited, personal, non-exclusive, non-transferable, revocable licence to access and use the content for your own personal, non-commercial development, for as long as your access is valid.

You may not:

  • copy, download (except where a download function is provided), record, screen-capture or reproduce the content;

  • share, distribute, publish, upload or make the content available to anyone else;

  • use the content to teach, coach, train or deliver services to third parties, whether paid or unpaid;

  • create derivative works from the content;

  • remove or obscure any ownership or copyright notice.

If you are a coach, teacher, therapist or practitioner and wish to use this material with your own clients, players or students, a separate licence is required. Contact us at hello@byakku.com.

Unauthorised use may result in immediate termination of access without refund, and we reserve all further legal remedies.

12. Acceptable use

You agree not to use the Service unlawfully, not to attempt to gain unauthorised access to any part of it, not to interfere with its operation or security, and not to use it in any way that harms, harasses or infringes the rights of others.

We may suspend or terminate access, without refund, where these Terms are materially breached.

13. Third-party platforms

The Service is delivered through third-party platforms including our app platform, media hosting, funnel and payment providers. Your use of those platforms is also subject to their own terms and privacy policies. We are not responsible for the acts, omissions, availability or security of third-party platforms, though we choose our providers with care.

14. Availability and changes to the Service

We aim to keep the Service available and working well, but we do not warrant uninterrupted or error-free access. Access may be temporarily unavailable due to maintenance, updates or technical issues.

We may add, modify, improve or remove content and features. Where we make a change that substantially reduces what you have paid for, we will notify you and, where appropriate, offer a proportionate refund or alternative.

We may discontinue the Service. If we do so while you hold a valid paid access period, we will refund the unused portion of what you have paid.

15. Limitation of liability

Nothing in these Terms excludes or limits our liability for:

  • death or personal injury caused by our negligence;

  • fraud or fraudulent misrepresentation;

  • gross negligence or intentional misconduct;

  • any liability that cannot lawfully be excluded or limited under Finnish or applicable mandatory consumer law.

Subject to the above, and to the fullest extent permitted by law:

a) We are not liable for indirect, consequential, special or incidental loss, including loss of profit, loss of opportunity, loss of competitive result, loss of contract or loss of data.

b) We are not liable for any loss or damage arising from your failure to follow the health and safety provisions in Section 4, from your failure to seek medical advice where Section 4 required it, from your use of the Service in a manner it was not designed for, or from inaccurate or incomplete information you provided to us.

c) Our total aggregate liability to you arising out of or in connection with the Service is limited to the amount you actually paid us in the twelve (12) months preceding the event giving rise to the claim.

This allocation of risk reflects the nature of the Service: educational self-practice, used independently, without supervision, at a price that reflects that.

16. Personal data

We process personal data in accordance with the EU General Data Protection Regulation (GDPR) and Finnish data protection law. How we collect, use, store and protect your data — and the rights you have over it — is set out in our Privacy Policy.

Where you voluntarily share health-related information with us, that information is treated as a special category of personal data under GDPR Article 9. We process it only with your explicit consent, only for the purpose of assessing suitability and adapting practice, and we do not share it with third parties except where you have asked us to or where the law requires it.

17. Changes to these Terms

We may update these Terms from time to time. The current version is always published on this page with the date of last update. Where a change materially affects your rights, we will notify you by email or in-app before it takes effect. Continued use of the Service after that point constitutes acceptance of the updated Terms.

18. Governing law and disputes

These Terms are governed by the law of Finland.

If you are a consumer resident in another EU/EEA country, you also retain the benefit of any mandatory consumer protection provisions of your country of residence, and you may bring proceedings in the courts of that country.

Before going to court, we would like the chance to put things right. Please contact us first at hello@byakku.com — most issues can be resolved directly and quickly.

Finnish consumers may also seek advice from the Consumer Advisory Service (Kuluttajaneuvonta, kkv.fi) or refer the dispute to the Consumer Disputes Board (Kuluttajariitalautakunta, kuluttajariita.fi). Consumers elsewhere in the EU may also use the European Commission's Online Dispute Resolution platform.

If you are a business customer, including an academy, club or federation, disputes are settled by the District Court of Helsinki, Finland.
