1.2              Any terms which deviate from these are not recognised by Lykon, unless Lykon has explicitly agreed to their validity in written form.

1.3              Lykon operates an online platform under the URL and, where you can acquire over-the-counter, prescription-free medical products in the form of medical self-tests and health products and whereby Lykon, offers a platform for innovative diagnostic methods in the healthcare sector. Lykon also offers an app in a freemium and a premium version with additional tests and services. Lykon activities comprise the development, marketing, and sale of health products and associated services. The products acquired from the Lykon platform or from the app can be used at home in order to carry out medical self-tests. If an analysis and/or evaluation in a laboratory is required, you can send the corresponding tests you carried out and the associated materials and substances directly back to Lykon. In such a case, please consider the package inserts and instructions for use. Every test kit has an online ID. If you log in to your user account in the Lykon platform portal you will be prompted to enter the online ID. This will link your user account with the online ID, activating the test for you. When carrying out and sending the test, only the materials and packaging included in the delivery must be used. Lykon will pass your test and the online ID on to a laboratory where the test can be analysed and evaluated. After the test has been analysed, the laboratory will send the results together with the online ID back to LykonDX GmbH, who will make these available in your user account.

1.4              As well as providing the self-tests and their results, Lykon offers plenty of information and consulting services relevant to the self-tests you carry out at, or via the app. This information will help you to better understand the results of your tests and will provide you with any necessary practical measures you can take in order to improve any unsatisfactory test results. This includes recommendations about foods you should avoid or eat more often, as well as general tips and information about how you can improve your health and wellbeing in both a general sense and with regard to more specific aspects. Among other things, the premium version of the app also offers offline nutritional advice

1.5              The app is available from the Google Play Store and the Apple App Store. The download requires prior registration with the respective app provider and the installation of the necessary installation software. The App Provider's terms and conditions and data protection regulations apply to the App Provider's services.

1.6              For the purpose of the analysis and evaluation of the products you have acquired and self-tests carried out, as well as the provision of results and the aforementioned information in your user account, it is required that the respective laboratory cooperates with Lykon with regard to the relevant product, and provides Lykon with the data relevant to this analysis, and thus that both the laboratory and Lykon collect and process this data. The data will only be provided to the relevant laboratory with your online ID, and will not reveal any information about your personal data or yourself. Lykon will ensure that the relevant laboratory adheres to the valid laws and regulations by means of a contract which complies with the valid data protection regulations for the collection and processing of all data.

3.4              After placing an order, you will receive an order acknowledgement via e-mail to the e-mail address you specified during the order process. This order acknowledgement is not an acceptance of the offer, but rather information regarding the receipt of the order and a reiteration of the order details.

3.5              The contract for the delivery of products (and, if applicable, for the execution of analyses and evaluations including the provision of the corresponding results from Lykon) is concluded with the order confirmation or invoice.

In particular, Lykon does not guarantee that the products or services offered on the Lykon platform or in the app can be delivered, acquired, or retrieved in any country outside of Germany.

3.6              Insofar as the analysis and the evaluation of the self-test purchased and carried out by you is not executed by Lykon itself but rather by a laboratory, then the analysis and evaluation will comply with the specifications on the package insert and instructions for use. You can view the results of the analyses and evaluations of the self-tests you have purchased and carried out by means of your user account on the Lykon platform or in the app, by activating your online ID and logging in using your access data.

5                            Revocation instruction

Revocation instruction

You have the right to revoke this contract within fourteen days without providing reasons.

The revocation period is fourteen days from the day on which you or a nominated third party who is not a carrier received the goods or, if you receive similar goods within the scope of a regular delivery over a specified time period, it is the day on which you or a nominated third party who is not a carrier received the first product.

In order to exercise your right for revocation, you must contact us

LykonDX GmbH, Schönhauser Allee, 10435 Berlin, – Fax: 030 - 220 122 391

with a clear explanation (e.g. a letter included in the post, telefax, or e-mail) for your decision to revoke this contract. You may use the attached sample revocation form for this, but using it is not mandatory.

To meet the revocation period, it is sufficient if you send us a notification of your desire to exercise your right of revocation before the revocation period has expired.

Consequences of revocation

If you revoke this contract, we shall return all payments we received from you including delivery costs (excluding any additional costs which may have arisen if you chose a special type of delivery other than our cheapest standard form) promptly and at the latest within fourteen days from the day on which we received your notification regarding the revocation of this contract. For this repayment, we will use the same payment method which you used for the original transaction, unless we have explicitly agreed to a different method with you separately, but no fees will apply to this repayment in any case. We may refuse to carry out a repayment until we have received all the goods or until you have provided evidence to show that you have send the goods, whichever comes first.

You must return the goods to us promptly, on any account within fourteen days from the day on which you notified us of the revocation of this contract at the latest. The deadline will be adhered to if you send the goods to us before fourteen days have expired.

You shall bear the direct costs of the return.

You shall only be liable to pay for any possible loss in value of the goods if this loss in value is attributable to you handling the goods in a manner that is not necessary to examine the properties, characteristics, or function of the goods.

If you have requested for a service to commence during the revocation period, then you must pay an adequate amount which is in proportion to the extent of the service already provided in comparison with the full coverage of the contract at the time you informed us of the revocation with regard to this contract.

Special instructions

There is no right of revocation for contracts which involve the delivery of goods which perish quickly or which have very short expiry dates, or for contracts which involve the delivery of sealed goods which are not suitable for return due to health or hygiene reasons if the seal was removed after delivery.

You must then reach a final agreement with us regarding the payment or rescind the transaction.

9.7              Delayed payments when purchasing on account will result in default charges of a predetermined amount as well as costs for appropriate warnings. In the event of unsuccessful internal dunning, the bank can hand over the outstanding claim for debt collection to a collection agency. In such a case, you may incur costs for legal action taken by the collection agency and potentially for legal representation.

9.8              Should you choose the ‘purchasing on account’ option, you explicitly consent to have your personal data (first name, surname, address, e-mail, telephone number, birthdate, IP address, gender) as well as data required to process the transaction (product, invoice amount, interest rate, maturities, total amount, invoice number, taxes, currency, order date, and order time) transmitted to payolution GmbH in order to process this payment method. payolution GmbH has a legitimate interest in this data as it requires and uses it in order to carry out risk assessments.

9.9              In order to review the creditworthiness of the customer, queries shall be made and information shall be requested from publicly accessible databases and credit reporting agencies. By accepting these T&Cs, you expressly agree that credit information can be obtained from the following providers:

    • CRIF AG, Hagenholzstrasse 81, CH-8050 Zürich
    • CRIF GmbH, Dessauerstraße 9, D-80992 Munich

payolution GmbH will relay your bank details (particularly your sort code and account number) to SCHUFA Holding AG for the purpose of an account number verification. SCHUFA will first use this data to check if the bank details you have provided are plausible. SCHUFA will check if the data to be used for the inspection is saved in your database where applicable and will then relay the result of the verification to payolution Gmbh. No additional data exchange, disclosure of creditworthiness information, relay of deviating bank details, or saving of your data in the SCHUFA database shall take place for the purpose of the account number verification. Only the fact that your bank details have been checked will be saved by SCHUFA for evidence purposes.

We would like to point out that you can revoke this consent to the data transfer at any time, even without giving reasons.
