In order to make purchases in our Shop, or when requesting Services, you may be invited to share personal information such as name, place of residence, email, telephone, health information, date of birth, etc (“Service Information”).

For more details on how we protect your personal data please see our Privacy Policy.

When purchasing in our online Shop, a contract of sale is concluded when we take Your order. Prices marked on the online shop do not constitute an offer in the legal sense. The customer will receive confirmation of the receipt and the taking of the order by email.

Product delivery

The Product will be delivered to the addressee submitted by You. We reserve the right to make a partial delivery, provided that this appears advantageous for efficiently processing the order and the partial delivery is not exceptionally unreasonable for the customer. The customer will not be charged for additional expenses incurred by part deliveries.

-- Right of Withdrawal, Cancellation and Return Policy --

You have the right to cancel this contract within fourteen (14) days without giving any reason. The cancellation period is fourteen days from the day on which you or a third party named by You, who is not the carrier, took possession of the goods.

In order to exercise your right of cancellation of the order or return, you must contact us at: info@colorimetrix.com with a clear explanation informing Us of your decision to cancel the Order contract, the Order reference number, your name and address used to contract the Service or receive the Product. To meet the cancellation deadline, it is sufficient for you to send your communication regarding your exercise of the right of cancellation before the cancellation period expires.

Our return policy for non-digital Products that are purchased through the Shop lasts for 14 days. If more than 14 days have gone by since you have received your purchased product, unfortunately we can’t offer you a refund or exchange.

Consequences of cancellation

If You withdraw from this contract, We will return all payments to You that We have received from You, including the delivery costs (with the exception of the additional costs that result from the fact that You chose a different type of delivery than the cheapest standard delivery We offer), immediately and at the latest within fourteen days from the day on which we received notification of your cancellation of this contract. For this repayment, We use the same means of payment that You used in the original transaction, unless expressly agreed otherwise with You; under no circumstances You will be charged any fees for this repayment.

We can refuse repayment until We have received the goods back or until You have provided proof that You have returned the goods, whichever is the earlier. You must return or hand over the goods to Us immediately and in any event no later than fourteen days from the date on which You inform us of the cancellation of this contract. The deadline is met if You send off the goods before the period of fourteen days has expired. You bear the cost of returning the goods.

You only have to pay for any loss in value of the goods if this loss in value is due to handling that is not necessary for checking the nature, properties and functionality of the goods; except in the cases described in the Exclusion clause below.

Exclusion of the right of withdrawal

Orders cannot be revoked for sealed goods, e.g. medicinal products or medical devices, which are not suitable for return for reasons of health protection or hygiene, if their seal was removed after delivery; or for goods that are tailored to the personal needs of the consumer; or for goods that can spoil quickly when opened. For these reasons, the right of withdrawal is excluded for opened products.

-- End of Right of Cancellation and Return Policy --

Returns of physical products

To return a Product ship the Product including the receipt or proof of purchase to the sender address from where You received the Product.

Shipping costs for returning a Product are non-refundable. Defect Products can be requested to be replaced by a comparable Product. Depending on where you live, the time it may take for your exchanged product to reach you may vary. Some Products are limited in quantity and might therefore be not possible to replace them or the replacement period might be longer.

Damages which are brought about through the customer’s improper actions in assembling, attaching, servicing or storing the goods provide no grounds for claims under warranty against Us. The customer can find information on proper usage in the manufacturer’s instructions for use.

Customers are to report defects to the seller within 1 month of receiving the goods. No warranties apply if the seller fraudulently concealed a defect or undertook a guarantee of the properties and condition of the goods. If goods are delivered with obvious damage to the packaging or the contents, the customer should complain about this immediately to the carrier/freighter, without prejudice to its rights under guarantee, and immediately get in contact with the seller by email, so that these rights can be protected when dealing with the carrier/freighter. In the case of a refund, you are responsible for the Product until it has been returned and we do not guarantee that your returned Product will be refunded until it is successfully returned to us. Do not send the Products back to the manufacturer.

We reserve the right to refuse to issue a refund or only issue a partial refund on returned Products (e.g., when a returned Product does not fulfil the return terms as set out above or when we are not able to review a Product because it has not been returned to us successfully or in an acceptable state).

Once your return is received and inspected, we will (if applicable) send you an email to notify you that we have received your returned Product and notify you of the status of your refund (approval or rejection). If approved, then your refund will be processed, and a credit will automatically be applied to your original method of payment within a certain amount of days. If rejected by your payment method, we will provide information on why that is the case.
