Terms and Conditions

TWINDO Sports Nutrition Advice Terms and Conditions

Last updated: 16 August 2026

Article 1. To whom do these terms and conditions apply?

1.1 These terms and conditions apply to all agreements between TWINDO Sports Nutrition Advice (Rietveen 2, 2912 SK Nieuwerkerk aan den IJssel, Chamber of Commerce registration no. 95241647) and the client, including agreements concluded via the TWINDO One app.

1.2 We shall only deviate from these terms and conditions if this has been agreed in writing.

1.3 The client’s own terms and conditions shall not apply.

1.4 Under a consumer this refers to a natural person who is not acting in the course of a profession or business.

1.5 Under a corporate client This refers to a company, sports club, sports association, foundation or sole trader who enters into the agreement in the course of their professional or business activities. In other words, not as a private individual. We always enter into agreements for presentations, workshops and web design with a business client (see Article 11.5).

Article 2. What we offer

2.1 We offer the following services:

• TWINDO One: an app with three subscription tiers (Today, Check, Progress) that provides personalised daily nutritional advice. Check and Progress also include a food diary with regular reports and feedback from a coach. Progress is the most comprehensive tier: it includes a permanent dashboard, a daily counter, a detailed PDF report sent by email, personalised coaching sessions and WhatsApp contact with the coach.
• Sports Nutrition Advice Centre: a free point of contact for quick enquiries or to get to know us, open to everyone.
• Lectures, presentations and workshops on sports nutrition.
• Web design for sports clubs and sports businesses.

2.2 We provide evidence-based nutritional advice: based on the information provided by the client and on generally recognised, scientifically underpinned dietary guidelines.

2.3 We may refuse an order without having to give a reason.

Article 3. When is the contract concluded?

3.1 For presentations, workshops and web design: as soon as the client accepts our quotation by email.

3.2 For TWINDO One: as soon as the client signs up for the free 10-day trial period. This constitutes the conclusion of the contract, even if the client has not yet made any payment at that point.

3.3 We always send a confirmation following registration or approval. With TWINDO One, the automatic confirmation email is sufficient.

3.4 Verbal agreements are only valid once they have been confirmed in writing by email.

3.5 The client is obliged to provide us with complete and accurate information.

3.6 In the case of presentations, workshops and web design, the obligation to pay arises at the time the contract is concluded (Clause 3.1). With TWINDO One, there is no obligation to pay during the free trial period; this only arises when the client switches to a paid subscription (Article 4.6). If the client is a consumer (Article 1.4), the right of withdrawal set out in Article 11 applies; this does not apply to business clients (Article 1.5).

Article 4. Prices and payment

4.1 All our prices are exempt from VAT (Small Business Scheme).

Presentations, workshops and web design

4.2 You can pay via a secure payment link on the invoice, or by bank transfer. The payment link accepts iDEAL, Wero, Bancontact, credit cards, Apple Pay and Google Pay, processed by Mollie B.V. We do not have access to your payment details ourselves.

4.3 We issue an invoice immediately upon acceptance of the quotation. The payment term is 14 days.

4.4 If you do not pay on time, we will first send you a reminder. If you do not respond within 7 days, we will send a formal demand for payment, including statutory interest and collection costs, and you will be given a further 7 days to pay before we refer the matter to a debt collection agency or bailiff.

TWINDO One subscription

4.5 The first 10 days are always free, with no need to enter any payment details.

4.6 If, following the trial period, you decide to continue with a paid subscription (Today, Check or Progress), we will process the first payment via Mollie (iDEAL, credit card or Bancontact). From that point onwards, we will set up a standing authorisation so that the subscription is automatically renewed, unless you cancel in good time (clause 10.5).

4.7 The current prices for each level are listed on the website and in the app.

4.8 If an automatic payment fails, we will let you know and you will be given the opportunity to make the payment. If payment is not received, we may suspend or terminate your access.

4.9 Switching between levels. If you upgrade to a higher tier (for example, from ‘Today’ to ‘Check’), this will take effect immediately and we will charge you the subscription fee for the new tier straight away. Any amount you have already paid for your previous tier will remain as it is; it will not be refunded or offset against future charges. If you switch to a lower tier, this will only take effect on your next renewal date; until then, you will retain your current tier.

Article 5. How we provide our services

5.1 We carry out our services to the best of our ability, in accordance with the agreed schedule.

5.2 If you fail to keep to your own appointments (for example, a coaching session), this may delay the process.

5.3 We may suspend our services in the event of outstanding invoices, and suspend access to TWINDO One if a subscription payment fails.

Article 6. TWINDO One

6.1 TWINDO One has three levels:

• Today: daily automatic nutritional advice (portions and timing), based on the profile and training plan provided by the client.
• Check: everything from ‘Today’, plus a food diary and a report every four weeks with personalised feedback from the coach.
• Progress: the full package: everything included in Check, plus a permanent dashboard, a daily counter, a comprehensive PDF report sent by email, a personal coaching session every four weeks and ongoing contact via WhatsApp.

6.2 TWINDO One automatically calculates the daily nutritional recommendations using complex calculation algorithms, based on evidence-based nutritional principles and the data entered by the client. The medical disclaimer in Article 13 applies to all levels.

6.3 The client is responsible for keeping their profile, training plan and (for Check/Progress) food diary up to date. We accept no liability if the advice is not appropriate because this information is incorrect or out of date.

6.4 TWINDO One is available in Dutch and English.

6.5 Access is via a personal, unique link that you will receive by email. No password is required.

Article 7. Coaching at Check and Progressie

7.1 With Check and Progress, the sports nutrition coach reviews your food diary every 4 weeks and provides personalised, written feedback via the app.

7.2 With Progressie, you’ll also receive a comprehensive PDF report by email, a personal coaching session (by telephone or online, every 4 weeks) during which the coach will discuss the report and answer your questions, and ongoing contact via WhatsApp.

7.3 We recommend that you play an active part: keeping your food diary honestly and up to date, and attending your scheduled consultation, will give the best results.

7.4 If you wish to cancel a coaching session, please do so at least 12 hours in advance (see Articles 10.3 and 11.2).

Article 8. Sports Nutrition Advice Centre

8.1 The Sports Nutrition Advice Centre is a free service for quick enquiries about sports nutrition and to find out more. It is open to everyone, even if you do not have a TWINDO One subscription.

8.2 You can contact us by email (info@twindo-sportvoedingsadvies.nl), WhatsApp and the online form.

8.3 As this is free of charge, there is no cancellation or refund policy.

8.4 No rights may be derived from answers provided via the Sports Nutrition Advice Centre. For comprehensive, personalised advice, please refer to TWINDO One.

Article 9. Presentations and workshops

9.1 We organise lectures, presentations and workshops on sports nutrition, either online or on-site.

9.2 We tailor the content to your requirements.

9.3 For on-site activities, the client shall provide a suitable venue and the necessary technical equipment.

9.4 Presentation materials remain our property.

9.5 Workshops. A minimum of 6 participants is required. If there are fewer than 6 registrations 7 days in advance, we can reschedule the workshop by mutual agreement. Maximum of 10 participants; anyone registering later will be placed on a waiting list or referred to a later date. The client is responsible for organising participant registrations.

9.6 Travel expenses. €0.25 per kilometre (return) from Nieuwerkerk aan den IJssel, based on the shortest route in Google Maps. Journey times of up to 45 minutes one way are free of charge; for any time exceeding this, we charge €12.50 per additional quarter of an hour, both ways. These costs are specified in advance in the quotation and are invoiced separately.

Article 10. Arrangements, cancellation and termination

10.1 Commitments are fulfilled on time.

10.2 If you wish to cancel, please do so by email. This takes effect from the moment we receive it. We will always arrange a new appointment in consultation with you.

10.3 You must cancel a coaching session (Progressie) at least 12 hours in advance. There is no cancellation policy for the Sports Nutrition Advice Centre.

10.4 For the cancellation of presentations and workshops: see clause 11.3. For the cancellation of web design: see clause 11.4.

10.5 Cancel TWINDO One. You can cancel your subscription at any time via the app, provided you do so before your next renewal date. That renewal date will then become the actual end date of your subscription: you will retain access until that point, and the subscription will not be renewed thereafter. Subscription fees already paid will not be refunded or offset. If, however, you wish to switch to a different tier (upgrade or downgrade), Article 4.9 applies.

Article 11. Cancellation, refunds and the right of withdrawal

11.1 Right of withdrawal – applies only to TWINDO One. The statutory right of withdrawal applies exclusively to consumers. Of our services, TWINDO One is the only one provided to consumers (see 11.5 for our business services).

During the 10-day free trial period, we do not ask for any payment details and your account will not automatically be converted into a paid subscription. Only when the client themselves, through a separate, deliberate action, starts a paid subscription (Article 4.6) – whether immediately after the trial period or at a later date – does a payment obligation arise. At that point, a 14-day withdrawal period begins, regardless of how much time has elapsed since the trial period ended.

The client may withdraw from the contract within those 14 days without giving any reason. The easiest way is to send a clear statement by email to helpdesk@twindo-sportvoedingsadvies.nl that you are cancelling the contract (a standard form is not required). If you would still like to use a form, you can use the model form provided by the Netherlands Authority for Consumers and Markets: https://www.acm.nl/nl/publicaties/publicatie/12754/Modelformulier-ontbinding-of-herroeping. We will then refund the amount for the remaining subscription period within 14 days of receiving notice of cancellation.

11.2 Cancelling a Progress coaching session. If you cancel more than 12 hours in advance, your appointment will be rescheduled to the next available slot. If you cancel within 12 hours, or fail to attend, your appointment for that session will be forfeited.

11.3 Cancellation of presentations and workshops. If you cancel more than 14 days in advance, there is no charge and we will refund the full amount. If you cancel between 7 and 14 days in advance, you will be liable for 50% of the price. If you cancel less than 7 days in advance, the full price is due.

11.4 Cancelling a web design project. You may terminate a web design project at any time before completion. We quote for web design projects at a fixed price, so in the event of cancellation, we charge the portion of that price corresponding to the percentage of the project we have already completed at that point. We do not charge for the part of the work that has not yet been carried out.

11.5 Business customers. We always conclude presentations, workshops and web design projects with business clients (see Article 1.5 for the definition). Consequently, no right of withdrawal applies to these services; the cancellation rules set out in 11.3 and 11.4 apply immediately and in full.

Article 12. What we expect from the client

12.1 The client:

• follows the automated advice from TWINDO One as intended;
• keeps their profile, training plan and (for Check/Progress) food diary accurate and up to date;
• reports any changes in his health straight away;
• if in doubt about medical matters, consult a doctor;
• provides Progressie, during coaching sessions, with open and comprehensive information about their health, medication use, allergies and any medical conditions.

12.2 The client remains responsible at all times for their own health and for following advice, including the automated advice provided by TWINDO One.

Article 13. Limits of our advice

13.1 TWINDO Sports Nutrition Advice provides sports nutrition advice and coaching, including via TWINDO One. This does not constitute medical treatment. We focus on healthy athletes. If a client has a medical condition that affects our sports nutrition advice, we will not provide nutritional advice on that specific aspect: as sports nutrition coaches, we are not registered dietitians and are not permitted to do so. In such cases, we refer the client to a registered dietitian. Our other, general sports nutrition advice via TWINDO One remains available as usual (see 13.2).

13.2 With Vandaag and Check, we have no direct contact with the client and do not actively ask about medical complaints, conditions, medication use or medical indications; the automated advice therefore does not take these into account. It is the client’s own responsibility to check this for themselves and, if necessary, to consult a doctor. Should the client nevertheless wish to report a medical condition to us, they may do so via helpdesk@twindo-sportvoedingsadvies.nl. Only in the case of Progressie, during a face-to-face coaching session, can we identify a reported medical condition; in such cases, Article 13.1 also applies. If the client continues to use TWINDO One or any of our other services after we have drawn their attention to this, they do so at their own expense and risk insofar as the relevant medical condition is concerned; we shall not be liable for any consequences arising therefrom.

13.3 In the event of an acute, life-threatening situation, we strongly advise the client to seek professional help immediately (for example, by dialling 112). At Progressie, we may, in such a situation, suspend the personal coaching session until the situation is under control. The subscription and the other components of TWINDO One will continue as normal; this does not constitute a termination or suspension of the agreement as a whole. As soon as the situation allows, we will resume the coaching session as normal.

13.4 We cannot guarantee that you will achieve your goal: results vary from person to person and depend, amongst other things, on your commitment, discipline, personal circumstances and other factors beyond our control.

Article 14. Who is permitted to use what

14.1 The regular reports, coach feedback and daily nutritional advice provided by TWINDO One are for your personal use.

14.2 Our methodologies, materials, working methods and TWINDO One itself (including the algorithm, source code and design) remain our property.

14.3 You may use the reports and advice for your own purposes, but you must not use them for commercial purposes or distribute them.

14.4 You must not transfer our methodologies, working methods or TWINDO One to others, use them for your own commercial activities, or attempt to reverse-engineer the underlying algorithms.

Article 15. Confidentiality and privacy

15.1 We treat all client data as confidential, in accordance with the GDPR.

15.2 We only use data for the purpose for which you provided it.

15.3 You can find our full privacy policy at: https://twindo-sportvoedingsadvies.nl/privacy-policy

Article 16. Liability

16.1 We shall not be liable for any loss arising from the implementation of our advice or coaching, including the automated advice provided by TWINDO One.

16.2 Our liability is limited to the amount paid out under our liability insurance.

16.3 In all cases, our liability shall be limited to the invoice amount for the relevant order. Or, in the case of TWINDO One, to a maximum of the subscription fees you have paid over the past 12 months.

16.4 We shall not be liable for any damage arising from you providing incorrect or out-of-date information, for example in your profile, training plan or food diary.

16.5 We do our best to ensure that TWINDO One remains readily available, but we do not guarantee uninterrupted availability and accept no liability for any loss or damage resulting from temporary disruptions, maintenance or the app being unavailable.

16.6 The exclusions and limitations of liability set out in this clause shall not apply in the event of wilful misconduct or gross negligence on the part of TWINDO Sportvoedingsadvies.

Article 17. Termination of the contract

17.1 We may terminate the contract with immediate effect in the event of:

• non-payment following a reminder;
• providing incorrect information;
• inappropriate behaviour;
• misuse of TWINDO One, such as reverse engineering or sharing your access code with others.

17.2 If we terminate the contract, the payment obligation shall remain in force and we shall not refund any services paid for in advance. Except where the statutory right of withdrawal set out in Article 11 applies.

Article 18. Complaints

18.1 You must report any complaints in writing within 14 days of them arising.

18.2 We deal with complaints as quickly as possible and respond within 30 days.

Article 19. Force Majeure

19.1 Force majeure refers to circumstances beyond our control that prevent performance in whole or in part: illness, accident, death in the immediate family, strikes, fire, power cuts, internet or telecoms disruptions, disruptions affecting third parties we engage (such as our hosting provider or payment service provider), government measures and other causes beyond our control.

19.2 In the event of force majeure, we may suspend or terminate the contract (in whole or in part) without being liable to pay compensation.

19.3 If we are temporarily unable to deliver, we will let you know as soon as possible and, in consultation with you, arrange a new date for coaching sessions, presentations or workshops.

19.4 If the force majeure lasts for more than 30 days and it becomes definitively impossible to fulfil the agreement, both we and the client may terminate the agreement. We will then refund any sums already paid on a pro rata basis for the part that has not yet been delivered.

Article 20. Governing law

20.1 This agreement shall be governed by and construed in accordance with Dutch law.

20.2 We shall refer any disputes to the competent court in the judicial district where we are based.

20.3 If you are a consumer within the EU and we are unable to reach a mutual agreement, you can also submit your complaint via the European Commission’s Online Dispute Resolution platform: https://ec.europa.eu/consumers/odr. We are not required to be members of a disputes committee, but we treat every complaint received via this platform just as seriously as a complaint made directly to us (see Article 18).

Article 21. Final provisions

21.1 Should any provision of these terms and conditions be found to be invalid, the remaining provisions shall continue to apply.

21.2 We may amend these terms and conditions. Any amendments will be made public by publishing the amended terms and conditions on our website; we will not inform clients of this separately or proactively. Amendments come into effect immediately upon publication. If a client does not agree with an amendment, they may terminate the agreement at any time free of charge pursuant to clause 10.5.
