General Terms and Conditions (Terms of Service)

Adoxin UG (haftungsbeschränkt) (hereinafter the "Organizer") · Status: August 2026

These terms and conditions form part of the contract concluded between the Organizer and the participant/customer for participation in learning journeys and training programs (such as the "Wind Energy Learning Journey"). Where the program includes travel services within the meaning of §§ 651a et seq. of the German Civil Code (BGB), the statutory provisions on package travel apply in addition; deviating provisions in the respective program description, offer or booking confirmation take precedence.

Where these terms use the term "durable medium", the definition in § 126b BGB applies.

1. Booking, conclusion of contract

1. With the registration, the customer makes a binding offer to the Organizer to conclude a contract.
2. The registration is made by the registering party also on behalf of all further participants named in the registration. The registering party is responsible for ensuring that the contractual obligations of all named participants are fulfilled.
3. Registration may be made in writing, verbally, by telephone or electronically (e.g. email or online form) after the customer has received the pre-contractual information required by law. Where the program constitutes package travel, the customer receives the standard information form pursuant to Art. 250 § 2 EGBGB before conclusion of the contract.
4. The contract is concluded upon acceptance by the Organizer (booking confirmation/invoice). The Organizer transmits the booking confirmation to the customer on a durable medium.
5. If the content of the booking confirmation deviates from the registration, the booking confirmation constitutes a new offer. The contract is concluded when the customer accepts this new offer within the period stated in the booking confirmation, in particular by express declaration, down payment or full payment.
6. Note on the right of withdrawal: for package travel contracts concluded by distance communication, there is generally no statutory right of withdrawal. The statutory rights of cancellation and termination pursuant to §§ 651h, 651l BGB apply.

2. Minimum number of participants

1. The minimum number of participants is 7 persons, unless stated otherwise in the respective program description, and becomes part of the contract.
2. If the minimum number of participants is not reached, the Organizer may withdraw from the contract pursuant to § 651h (4) no. 1 BGB. The withdrawal must be declared no later than: 20 days before the start for programs of more than 6 days, 7 days before the start for programs of 2 to 6 days, and 48 hours before the start for programs of less than 2 days. An earlier withdrawal deadline stated in the program description or booking confirmation remains unaffected. The declaration of withdrawal is transmitted to the customer without delay on a durable medium.
3. Payments already made will be refunded without delay in the event of withdrawal due to failure to reach the minimum number of participants.

3. Payment, security certificate, documents

1. Where the program constitutes package travel, payments on the program price may only be demanded or accepted if the customer has previously received the security certificate (Sicherungsschein) in text form. In that case the Organizer provides the statutory insolvency protection pursuant to § 651r BGB.
2. Upon conclusion of the contract (and, where applicable, after delivery of the security certificate), a down payment becomes due. The amount of the down payment is stated in the program description, offer or booking confirmation.
3. The remaining balance is due no later than 35 days before the start of the program.
4. Program documents are transmitted in accordance with the booking confirmation. The Organizer may exercise a right of retention over documents until full payment has been made, to the extent legally permissible.
5. If the customer fails to make due payments in full, the Organizer may, after issuing a reminder with a deadline, withdraw from the contract and demand cancellation costs in accordance with Section 7. The customer remains free to prove that no costs or significantly lower costs were incurred.

4. Services, scope of services, third-party services, travel to the venue

1. The scope of the contractual services results from the program description, the offer and the booking confirmation as well as the information provided pursuant to Art. 250 EGBGB where applicable.
2. Travel to and from the program region (e.g. flights to/from Germany) is not part of the program package, unless expressly stated otherwise in the program description.
3. Where the program description designates individual services (e.g. hotel nights booked individually by the participant, optional exhibition tickets, optional excursions) as not being part of the package, these are third-party services for which the respective provider is the customer's contractual partner. This is indicated in the program description or booking confirmation.
4. Services which the customer books independently with third parties (e.g. additional excursions, events, private transfers) are not services of the Organizer.

5. Program language

1. The program is generally conducted in English, unless stated otherwise in the program description.
2. Individual program items may take place partly in German or other languages (e.g. during visits with local partners). Translation may be offered where organizationally possible; a claim to continuous interpretation exists only if expressly agreed in the contract.

6. Changes to services after conclusion of the contract

1. Changes to essential characteristics of travel services after conclusion of the contract are only permissible under the statutory conditions, in particular pursuant to § 651f BGB.
2. The Organizer will inform the customer of significant changes without delay on a durable medium. The customer has the statutory rights, in particular withdrawal or acceptance of a substitute offer, where the conditions are met.
3. Program changes for organizational reasons are permissible provided they do not significantly impair the overall character of the program and are reasonable for the customer — in particular changes to the order of program items, times, individual sessions or equivalent substitute sessions and speakers.
4. Price increase. The Organizer may unilaterally increase the program price if, after conclusion of the contract and before the start of the program, (a) the cost of passenger transport increases due to higher fuel or energy prices, (b) taxes or other charges for agreed services (e.g. tourist levies, port or security fees) increase, or (c) the exchange rates applicable to the program change. The Organizer will inform the customer clearly and comprehensibly on a durable medium of the price increase and its reasons, stating the calculation. A price increase is only effective if the notification reaches the customer no later than 20 days before the start of the program. If the price increase exceeds 8% of the program price, the customer may, within a reasonable period set by the Organizer, either accept the increase, withdraw from the contract, or request participation in a substitute program if offered. If the customer does not respond within the set period, the price increase is deemed accepted.
5. Price reduction. If the costs referred to above decrease after conclusion of the contract and before the start of the program, the program price is to be reduced accordingly to the extent required by law; the Organizer may deduct administrative costs actually incurred, to the extent permissible.

7. Cancellation by the customer, cancellation costs, substitute participants

1. The customer may withdraw from the contract only within 5 calendar days of registration, provided the withdrawal declaration is received by the Organizer no later than 5 working days before the start of the programme. The time of receipt of the withdrawal declaration by the Organizer is decisive. Withdrawal outside this window is not possible; the full programme price remains due.
2. In the event of a timely withdrawal in accordance with clause 7.1, no cancellation compensation is due and payments already made will be refunded in full. In the event of unavoidable, extraordinary circumstances which significantly impair the execution of the programme, the statutory provisions pursuant to § 651h BGB apply regardless.
3. The customer may declare on a durable medium, within a reasonable period before the start of the programme, that a third party assumes the rights and obligations under the contract (§ 651e BGB). The Organizer may object to the substitution if the third party does not meet statutory or contractual programme requirements. Customer and substitute participant are jointly and severally liable for the programme price and any reasonable additional costs. Substitution is possible even after the cancellation window in clause 7.1 has closed.
4. Brokered third-party services (e.g. separately arranged flights, insurance, visas, exhibition tickets) may be subject to deviating cancellation conditions and may incur additional costs in whole or in part in the event of cancellation.
5. The Organizer strongly recommends taking out travel cancellation insurance to cover cases where withdrawal is no longer possible under clause 7.1.

8. Services not used

If the customer does not make use of individual services for reasons not attributable to the Organizer, there is no claim to pro-rata reimbursement, to the extent legally permissible. The Organizer will make reasonable efforts to obtain reimbursement of saved expenses from service providers, insofar as a reimbursement claim exists.

9. Withdrawal and termination by the Organizer

1. The Organizer may withdraw before the start of the program if the minimum number of participants is not reached (Section 2) or if unavoidable, extraordinary circumstances significantly impair the execution of the program.
2. After the start of the program, the Organizer may terminate the contract if the participant persistently disrupts the program despite a warning or behaves in breach of the contract to such an extent that immediate termination is justified. Statutory claims remain unaffected.

10. Unavoidable extraordinary circumstances, force majeure, program risks

1. Unavoidable, extraordinary circumstances may make it necessary to adapt, postpone or replace services — in particular in the case of official measures, security situations, strikes, natural events, weather conditions, traffic obstructions or short-notice closures of facilities or industrial sites.
2. In such cases, the Organizer is entitled to offer equivalent substitute services or to adapt the program sequence to the extent necessary and reasonable.
3. Statutory rights of the customer, in particular pursuant to §§ 651h, 651l, 651m, 651n BGB, remain unaffected.

11. Liability of the Organizer

1. The Organizer is liable within the framework of the statutory provisions for the proper performance of the contractually owed services.
2. The Organizer is not liable for service disruptions in connection with third-party services which are not part of the package and have been designated as such.
3. The Organizer's liability for damages is limited to three times the program price in accordance with § 651p BGB, insofar as damage was caused neither intentionally nor through gross negligence. This does not apply to damage resulting from injury to life, body or health.

12. Obligations of the customer, notification of defects

1. The customer must report complaints without delay to the program management on site or to the Organizer in order to enable remedial action.
2. Complaint contact / emergency number during the program: primarily the program management on site (where designated); alternatively info@adoxin-group.com, phone +49 (40) 37 50 248 -57. As a rule, the managing director accompanies the program as program management/contact person.
3. If the customer culpably fails to notify a defect, statutory rights may be restricted.

13. Passport, visa, entry and health requirements, data transfer

1. The Organizer provides information on general passport and visa requirements and health formalities to the extent required by law. The customer remains responsible for compliance with the entry, residence, customs and health regulations applicable to them.
2. The customer must provide the Organizer with the data required for bookings, site access and entry requirements truthfully and in good time.
3. Depending on the venues and service providers, it may be necessary to transmit personal data to third parties (e.g. first name, surname, date of birth, nationality, email address; in individual cases also passport data), exclusively for the execution of the program, compliance with official or site-security requirements, or the confirmation/processing of booked services. Details are set out in our Privacy Policy.

14. Insurance

Unless expressly agreed, insurance is not included in the program price. The Organizer recommends in particular taking out travel cancellation insurance and international travel health insurance.

15. Set-off, assignment

1. Set-off against claims of the Organizer is only permitted with undisputed or legally established claims, to the extent legally permissible.
2. Assignment of the customer's claims under the contract to third parties is excluded, to the extent legally permissible.

16. Choice of law, place of jurisdiction

1. German law applies, unless mandatory consumer protection provisions provide otherwise.
2. For customers who are consumers, the statutory places of jurisdiction apply. For merchants and legal entities, the place of jurisdiction at the registered office of the Organizer (Hamburg) may be agreed, to the extent permissible.

17. Data protection and transfer of personal data in connection with the program

1. The Organizer processes the customer's personal data exclusively for the initiation, execution and processing of the booked services and to fulfil legal obligations. The privacy information on the Organizer's website applies in addition.
2. In the context of executing learning journeys, it may be necessary to pass on personal data of the customer to third parties, insofar as this is necessary for the organization, execution or lawful participation in individual program components. This includes in particular: first and last name, email address, where applicable telephone number, and in individual cases passport data.
3. Such data transfer takes place in particular to: companies, organizations or institutions visited during the program (e.g. for access registration, participant lists, security or access-management systems); accommodation providers, transport companies or other service providers; and authorities or governmental bodies where required for entry, residence or security regulations.
4. The transmitted data may be used by the respective recipients exclusively for the respective purpose, in particular for granting access, processing bookings, identity verification or compliance with legal requirements. The recipients do not use the data for their own advertising or marketing purposes.
5. Any further processing or transfer of personal data only takes place if the customer has expressly consented or if there is a legal obligation.

18. Dispute resolution

1. The Organizer is neither obliged nor willing to participate in dispute resolution proceedings before a consumer arbitration board.
2. Note: the former EU Commission platform for online dispute resolution (ODR platform) was discontinued on 20 July 2025.

19. Final provisions

Should individual provisions be or become invalid, the validity of the remaining provisions remains unaffected.
