Berliner Allee 72
13088 Berlin
(hereinafter referred to as "Trainer") and the clients (hereinafter referred to as "Customer") concerning the provision of Java training courses, which are offered, among other things, on the website https://www.happycoders.eu.
These training courses are exclusively for entrepreneurs within the meaning of § 14 BGB. Consumers (§ 13 BGB) are excluded from booking.
Deviating terms and conditions of the Customer are not recognized unless the Trainer expressly agrees to their validity in writing.
By entering into the contract, the Customer confirms that they have received and accepted these terms & conditions.
The Trainer offers courses and training in Java programming. The content, duration, and modalities of the training courses are derived from the respective service description on the website or an individual offer.
3.1
The presentation of the training courses on the website does not constitute a binding offer to conclude a contract, but serves solely for the information of potential contractual partners.
3.2
The Customer must submit an inquiry for a training course either via the contact form or by email. Based on this inquiry, the Trainer will create an individual offer. A contract is only concluded when the Customer accepts this offer in writing (e.g., by email) and the Trainer confirms this acceptance.
3.3
The Trainer reserves the right to reject inquiries without stating reasons.
3.4
The Trainer reserves the right to postpone or cancel confirmed appointments for important reasons (e.g., illness, force majeure). In this case, the Trainer will inform the Customer immediately and offer an alternative date. If no agreement on an alternative date is reached, payments already made will be fully refunded. Further claims, especially for travel or hotel costs, are excluded.
4.1
To secure the appointment, 50% of the agreed participation fee is due upon booking.
4.2
The remaining 50% must be received in the Trainer's account before the start of the training.
4.3
Payment is made exclusively by bank transfer to the account specified by the Trainer.
4.4
If the remaining payment is not received on time, the Trainer reserves the right to allow participation only upon immediate payment on site or upon presentation of a payment confirmation. If neither payment nor proof is provided, the Trainer is entitled to refuse participation. The claim for payment remains, unless the Trainer, out of goodwill, agrees to a cancellation or rebooking.
4.5
In case of default in payment, the Trainer is entitled to demand default interest at the statutory rate in accordance with § 288 para. 2 BGB.
5.1
Cancellations must be made in writing; email is sufficient.
5.2
For cancellations up to four weeks before the start of the training, any payments already made will be fully refunded. For cancellations between four and two weeks before the start of the training, 50% of the total amount will be charged. For cancellations less than two weeks before the start of the training or in case of no-shows, the full amount will be due.
5.3
Rebooking to another date is possible by arrangement; payments already made will be credited to the new date.
The Trainer reserves the right to make content-related, methodological, or organizational adjustments to the training, provided that these do not significantly alter the overall character of the event.
7.1
The Trainer is only liable for damages resulting from intent or gross negligence.
7.2
In the event of slight negligence in violating essential contractual obligations (cardinal obligations), liability is limited to the typical, foreseeable damage for the contract.
7.3
For all other cases of slight negligence, as well as for indirect damages, lost profits, or consequential damages, no liability is assumed.
7.4
The limitation of liability does not apply to injury to life, body, or health.
8.1
All training documents, presentations, and other materials are protected by copyright. The Customer receives a simple, non-transferable right of use exclusively for their own personal use during and after the training.
8.2
Any dissemination, reproduction, publication, or other use is prohibited without the express written consent of the Trainer.
Personal data is processed exclusively within the framework of applicable data protection laws. Details can be found in the privacy policy on the Trainer's website.
10.1
The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods (CISG).
10.2
If the Customer is a merchant, a legal entity under public law, or a special fund under public law, the exclusive place of jurisdiction for all disputes arising from the contractual relationship is Berlin.
10.3
Should individual provisions of these terms & conditions be or become invalid, the validity of the remaining provisions shall remain unaffected.
These terms & conditions supersede all previous versions. Amendments will only become effective if confirmed in writing.
