Terms of participation

Short and in the same order the questions come: when the contract is concluded, what it costs, what applies to cancellations and what happens with your information.

Courtesy translation. The German version of this page is the legally binding one.

1. Provider and scope

The provider of the workshops is Dennis Roßkopf, Grellstraße 37, 10409 Berlin. These terms apply to all open workshops and to in-house events, unless otherwise agreed in the quote.

The offer is aimed at companies, self-employed people and public institutions. Consumers may also take part; for them, section 9 applies in addition.

2. Registration and conclusion of the contract

Registration via the form is an offer to conclude a contract. The contract is only concluded when I expressly confirm participation by email.

A date runs from four registrations. Until it is confirmed, your registration is non-binding and free. You will know at least ten days in advance whether the date goes ahead. The invoice comes only after that.

3. Prices and payment

All prices are net prices and are subject to statutory VAT.

The invoice is sent after the date is confirmed and is payable without deduction no later than seven days before the date. For short-notice registrations it is due immediately.

The price includes participation, the materials, the example repository and coffee, tea and drinks on site. Travel, accommodation and lunch for participants are not included.

4. Cancellation by participants

Up to 14 days before the date, cancellation is free of charge.

From 14 to 7 days before the date, 50 percent of the participation fee is charged.

After that and in case of no-show, the full participation fee is charged.

If I only confirm a date within the last 14 days before it, you can cancel free of charge up to three days after the confirmation. Only after that do the stages above apply.

A substitute can be named at any time and free of charge, even on the day itself. That is the easiest way to avoid costs.

Cancellation is possible informally by email. What counts is receipt by me.

5. Cancellation by the provider

If the minimum number of participants is not reached, I cancel no later than ten days before the date. Amounts already paid are refunded in full.

In case of illness or other reasons for which I am not responsible, I offer an alternative date. If that does not suit, the full amount is refunded.

Further claims, in particular for reimbursement of travel and accommodation costs or lost profit, are excluded unless I am guilty of intent or gross negligence.

6. Procedure and cooperation

The published agenda is a plan. I reserve the right to adapt the emphasis to the group, as long as the outcome of the workshop does not suffer as a result.

For the hands-on parts, each participant needs their own laptop with a working development environment, an installed agent and a project that may be worked on. Without that, participation is possible but the practical benefit is considerably smaller.

Access to participants' production systems is neither required nor used in the workshop.

7. Materials, recordings and confidentiality

Materials and example code may be used and modified freely within your own company. Passing them on to third parties or using them for your own training offers is not permitted.

Photo, audio and video recordings are not permitted during the event, neither by me nor by participants. Screenshots of your own work are of course allowed.

What participants say about their systems, their code or their company stays in the room. That applies to me and I expect it from everyone else as well.

8. Liability

I am liable without limitation for intent and gross negligence and for damage resulting from injury to life, body or health.

In case of slight negligence I am liable only for breach of a material contractual obligation and only up to the foreseeable damage typical of the contract at the time of its conclusion.

The content taught in the workshop is experience-based knowledge. It does not replace an examination of the individual case and is not legal, data protection or security advice. I accept no liability for decisions participants take in their own systems on this basis.

9. Right of withdrawal for consumers

Consumers have the right to withdraw from the contract within 14 days of its conclusion without giving reasons. A clear declaration by email or post to the contact details above is sufficient.

In case of withdrawal I refund all payments already received without delay, at the latest within 14 days.

If the workshop is held before the end of the withdrawal period at your express request, proportionate compensation is payable for the service provided up to the withdrawal.

10. Final provisions

German law applies. If the contracting party is a merchant, a legal entity under public law or a special fund under public law, the place of jurisdiction is Berlin.

Should a provision be invalid, the rest of the contract remains valid.
