Article 3 – Applicability

These general terms and conditions apply to every offer from the entrepreneur and to every distance contract concluded between the entrepreneur and the consumer.
Before the distance contract is concluded, the text of these general terms and conditions will be made available to the consumer. If this is not reasonably possible, before the distance contract is concluded, it will be indicated that the general terms and conditions can be viewed by the entrepreneur and they will be sent free of charge at the request of the consumer.
If the distance contract is concluded electronically, notwithstanding the previous paragraph and before the distance contract is concluded, the text of these general terms and conditions can be made available to the consumer electronically in such a way that the consumer can easily store it on a durable medium. If this is not reasonably possible, before the distance contract is concluded, it will be indicated where the general terms and conditions can be consulted electronically and that they will be sent free of charge electronically or otherwise at the request of the consumer.
In the event that specific product or service conditions apply in addition to these general terms and conditions, the second and third paragraphs apply mutatis mutandis and the consumer can always invoke the applicable provision that is most favourable to him in the event of conflicting general terms and conditions.

Article 4 – The offer

If an offer has a limited period of validity or is made subject to conditions, this will be explicitly stated in the offer.
The offer contains a complete and accurate description of the products and / or services offered. The description is sufficiently detailed to allow a proper assessment of the offer by the consumer. If the entrepreneur uses images, they are a true representation of the products and / or services offered. Obvious mistakes or obvious errors in the offer do not bind the entrepreneur.
Each offer contains such information that it is clear to the consumer what rights and obligations are attached to the acceptance of the offer. This concerns in particular:

the price including taxes;
any delivery costs;
the way in which the agreement will be concluded and which actions are required for this;
whether or not the right of withdrawal applies;
the method of payment, delivery and implementation of the agreement;
the period for accepting the offer, or the period within which the entrepreneur guarantees the price;
the level of the rate for distance communication if the costs of using the technique for distance communication are calculated on a basis other than the regular basic rate for the means of communication used;
whether the contract is filed after conclusion, and if so, how it can be consulted by the consumer;
the way in which the consumer, before concluding the contract, can check the data provided by him under the contract and repair it if desired;
the languages in which the contract can be concluded, being English, German and Dutch;
the codes of conduct to which the entrepreneur is subject and the way in which the consumer can consult these codes of conduct electronically; and
the minimum duration of the distance contract in the event of an extended transaction.

Article 5 – The contract

The agreement is concluded, subject to the provisions of paragraph 4, when the consumer accepts the offer and meets the corresponding conditions.
If the consumer has accepted the offer electronically, the entrepreneur will immediately confirm receipt of acceptance of the offer electronically. As long as the receipt of this acceptance has not been confirmed by the entrepreneur, the consumer can dissolve the agreement.
If the agreement is concluded electronically, the entrepreneur will take appropriate technical and organizational measures to protect the electronic transfer of data and he will ensure a safe web environment. If the consumer can pay electronically, the entrepreneur will observe appropriate security measures.
The entrepreneur can – within legal frameworks – inform whether the consumer can meet his payment obligations, as well as all those facts and factors that are important for a responsible conclusion of the distance contract. If, on the basis of this investigation, the entrepreneur has good reasons not to enter into the agreement, he is entitled to refuse an order or request, stating reasons, or to attach special conditions to the execution.
The entrepreneur will send the following information with the product or service to the consumer, in writing or in such a way that it can be stored by the consumer in an accessible manner on a durable medium:

the visiting address of the establishment of the entrepreneur where the consumer can go with complaints;
the conditions under which and the manner in which the consumer can exercise the right of withdrawal, or a clear statement regarding the exclusion of the right of withdrawal;
information about guarantees and existing after-sales service;
the information included in article 4 paragraph 3 of these conditions, unless the entrepreneur has already provided this information to the consumer before the execution of the agreement;
the requirements for terminating the agreement if the agreement has a duration of more than one year or is indefinite.

In the event of an extended transaction, the provision in the previous paragraph only applies to the first delivery.

Article 6 – Right of withdrawal

When purchasing products, the consumer has the statutory right to dissolve the contract without giving any reason during 14 days. This reflection period commences on the day after receipt of the product by the consumer or a representative designated in advance by the consumer and announced to the entrepreneur.
In addition to that statutory period, the entrepreneur voluntarily grants the consumer a further 16 days, so that the consumer has 30 days in total in which to return a product. The conditions of this additional guarantee are set out in the entrepreneur's Refund policy. The additional period is a contractual promise of the entrepreneur and does not limit the statutory 14-day right in any way.
To exercise the right of withdrawal, the consumer informs the entrepreneur by an unequivocal statement, for example by email to hello@human-pro.com. The consumer may use the model withdrawal form set out in the Annex to these terms, but is not obliged to do so. To meet the deadline it is sufficient that the consumer sends the communication before the period has expired.
During the reflection period, the consumer will handle the product and packaging with care. He will only unpack or use the product to the extent necessary to assess whether he wishes to keep the product. If he makes use of his right of withdrawal, he will return the product with all accessories and – if reasonably possible – in the original condition and packaging to the entrepreneur, in accordance with the reasonable and clear instructions provided by the entrepreneur.
The consumer must return the product within 14 days of notifying the entrepreneur of the withdrawal.

Article 7 – Costs in case of withdrawal

If the consumer makes use of his right of withdrawal, at most the direct costs of returning the goods will be for his account. The entrepreneur refunds the cost of its standard delivery; where the consumer expressly chose a delivery method more expensive than the standard option, the surcharge is not refunded.
If the consumer has paid an amount, the entrepreneur will refund this amount as soon as possible and in any event no later than 14 days after the day on which the entrepreneur is informed of the consumer's decision to withdraw from the agreement. The entrepreneur may withhold reimbursement until the goods have been received back, or until the consumer has supplied evidence of having sent the goods back, whichever is the earlier.
Reimbursement is made using the same means of payment the consumer used for the original transaction, unless the consumer has expressly agreed otherwise. The consumer is not charged any fee for the reimbursement.

Article 8 – Exclusion of right of withdrawal

The entrepreneur can exclude the right of withdrawal of the consumer only in the cases provided for in paragraph 2, and only if the entrepreneur has clearly stated this in the offer, at least in time for the conclusion of the agreement.
Under Article 16 of Directive 2011/83/EU the right of withdrawal does not apply to:

goods made to the consumer's specifications or clearly personalised;
goods which are liable to deteriorate or expire rapidly;
sealed goods which are not suitable for return for reasons of health protection or hygiene, if they were unsealed after delivery;
goods which, after delivery, are inseparably mixed with other items according to their nature;
sealed audio or video recordings or sealed computer software, if unsealed after delivery;
individual newspapers, periodicals or magazines;
goods whose price is dependent on fluctuations in the financial market which the entrepreneur cannot control and which may occur within the withdrawal period.

The entrepreneur does not invoke the sealed-goods exclusion in the third indent above for its own products. Opened and used products may be returned in accordance with the entrepreneur's Refund policy, subject only to a possible reduction where an item is heavily used or damaged. This is a voluntary undertaking by the entrepreneur and goes beyond what the law requires.

Article 9 – The price

During the period of validity stated in the offer, the prices of the products and / or services offered will not be increased, except for price changes as a result of changes in VAT rates.
Contrary to the previous paragraph, the entrepreneur can offer products or services whose prices are subject to fluctuations in the financial market and over which the entrepreneur has no influence, with variable prices. This link to fluctuations and the fact that any stated prices are target prices are stated in the offer.
Price increases within 3 months after the conclusion of the agreement are only permitted if they are the result of statutory regulations or provisions.
Price increases from 3 months after the conclusion of the agreement are only permitted if the entrepreneur has stipulated this and:

these are the result of statutory regulations or provisions; or
the consumer is authorized to terminate the agreement with effect from the day on which the price increase takes effect.

The prices stated in the offer of products or services include VAT.
Discount codes are personal and cannot be transferred to other persons or user accounts unless otherwise stated.

Article 10 – Compliance and warranty

The entrepreneur guarantees that the products and / or services comply with the agreement, the specifications stated in the offer, the reasonable requirements of reliability and / or usability and the legal provisions existing on the date of the conclusion of the agreement and / or government regulations. If agreed, the entrepreneur also guarantees that the product is suitable for other than normal use.
A warranty provided by the entrepreneur, manufacturer or importer does not affect the legal rights and claims that the consumer can assert against the entrepreneur under the agreement.

Article 11 – Delivery and implementation

The entrepreneur will take the greatest possible care when receiving and implementing orders for products and when assessing applications for the provision of services.
The place of delivery is the address that the consumer has made known to the company.
With due observance of what is stated in article 4 of these general terms and conditions, the company will execute accepted orders expeditiously, but at the latest within 30 days, unless a longer delivery period has been agreed. If delivery is delayed, or if an order cannot or only partially be executed, the consumer will be notified of this no later than 30 days after placing the order. In that case, the consumer has the right to terminate the contract without costs and the right to any compensation.
In case of dissolution in accordance with the previous paragraph, the entrepreneur will refund the amount that the consumer has paid as soon as possible, but no later than 14 days after dissolution.
If delivery of an ordered product proves to be impossible (e.g. customs of a certain country block the delivery of the product or service), the entrepreneur will at most provide a replacement product to the consumer. If the entrepreneur decides to send a replacement item to the consumer, it will be stated in a clear and comprehensible manner that a replacement item is being delivered and when. For replacement items the right of withdrawal cannot be excluded. The costs of a possible return shipment are for the account of the consumer.
The risk of damage and / or loss of products rests with the entrepreneur until the moment of delivery to the consumer or a pre-designated and announced representative to the entrepreneur, unless expressly agreed otherwise.

Article 12 – Cancellation, extension and duration

Cancellation

The consumer can terminate an agreement that has been concluded for an indefinite period and which extends to the regular delivery of products or services, subject to the agreed cancellation rules and a notice period of no more than one month.
The consumer can terminate a contract that has been concluded for a definite period and that extends to the regular delivery of products or services, at any time towards the end of the fixed term, with due observance of the agreed cancellation rules and a notice period of at most one month.
The consumer can cancel the agreements mentioned in the previous paragraphs:

at any time and not be limited to cancellation at a specific time or in a specific period;
at least in the same way as they have been entered into by him;
always with the same notice period as the entrepreneur has stipulated for himself.

Extension

A contract that has been concluded for a definite period and that extends to the regular delivery of products or services may not be automatically extended or renewed for a fixed period.
A contract that has been concluded for a definite period and that extends to the regular delivery of products or services may only be extended tacitly for an indefinite period if the consumer can cancel at any time with a notice period of no more than one month.

Duration

If an agreement has a duration of more than one year, the consumer may cancel the agreement at any time with a notice period of up to one month, unless the reasonableness and fairness oppose cancellation before the end of the agreed duration.

Article 12A – Subscriptions

The entrepreneur offers subscriptions under which a product is delivered repeatedly at the interval chosen by the consumer at the time of purchase. The interval, the price per delivery and any subscription discount are stated on the product page before the order is placed and are confirmed in the order confirmation.
A subscription is entered into for an indefinite period and continues until it is cancelled. Each delivery is charged at the moment it is prepared, at the price then applicable to the subscription.
The consumer can cancel a subscription at any time, without giving a reason, from his account or by emailing hello@human-pro.com. Cancellation takes effect from the next scheduled delivery, provided it is received before that delivery is prepared. Cancellation does not affect a delivery that has already been dispatched; the right of withdrawal and the Refund policy apply to that delivery in the normal way.
The entrepreneur will notify the consumer of any change to the price or interval of a subscription in good time before it takes effect, and the consumer may cancel with effect from the date the change takes effect.
The right of withdrawal in Article 6 applies to each individual delivery under a subscription, counted from receipt of that delivery.

Article 13 – Payment

Unless otherwise agreed, the amounts owed by the consumer must be paid within 14 days after the start of the cooling-off period as referred to in Article 6, paragraph 1. In the event of an agreement to provide a service, this period will commence after the consumer has received the confirmation of the agreement.
When prepayment has been stipulated, the consumer cannot assert any rights regarding the execution of the order or service(s) concerned before the stipulated prepayment has taken place.
The consumer has the duty to immediately report inaccuracies in payment details provided or stated to the entrepreneur.
In case of default by the consumer, the entrepreneur has the right to charge the reasonable costs made known to the consumer, subject to legal restrictions.

Article 14 – Complaints policy

The entrepreneur has a well-publicised complaints procedure and handles the complaint in accordance with this complaints procedure. Complaints can be submitted by email to hello@human-pro.com.
Complaints about the implementation of the agreement must be submitted to the entrepreneur within a reasonable time, fully and clearly described, after the consumer has discovered the defects.
Complaints submitted to the entrepreneur will be answered within a period of 14 days from the date of receipt. If a complaint requires a foreseeable longer processing time, the entrepreneur will reply within the period of 14 days with a notice of receipt and an indication when the consumer can expect a more detailed answer.

Article 15 – Applicable law and disputes

Agreements between the entrepreneur and the consumer to which these general terms and conditions apply are governed by Dutch law.
The choice of law in the previous paragraph does not deprive a consumer who is habitually resident in another Member State of the European Union or of the European Economic Area of the protection afforded to him by the mandatory provisions of the law of his country of habitual residence.
A consumer may bring proceedings against the entrepreneur before the courts of the Netherlands or before the courts of the Member State in which the consumer is domiciled. The entrepreneur may bring proceedings against a consumer only before the courts of the Member State in which the consumer is domiciled.
The entrepreneur is not affiliated with a consumer dispute resolution body and is not obliged, and does not undertake, to participate in alternative dispute resolution proceedings. Consumers are always free to approach the competent court or a consumer authority in their own country. The European Commission's Online Dispute Resolution platform was discontinued on 20 July 2025 and is no longer available.

Article 16 – Additional or different terms

Additional or deviating provisions from these general terms and conditions may not be to the detriment of the consumer and must be recorded in writing or in such a way that they can be stored by the consumer in an accessible manner on a durable data carrier.
