Terms & Conditions

Principles of Collaboration

These principles describe how I work with clients across all my areas of work — process facilitation, organisational development, and visual harvesting or illustration work. They apply to all projects unless we agree otherwise in writing. What a specific project includes, and what it costs, is set out in the individual offer; these principles cover the ground rules around it.

My aim is a collaboration that stays clear, fair, and transparent from first contact to close.

1. Rescheduling and cancellation

When we agree on dates, I reserve them exclusively for you and begin preparing in advance. Because a reserved date usually cannot be filled again at short notice, the following applies if you cancel or postpone a confirmed booking:

  • more than 4 weeks before the agreed date: no charge;

  • 4 to 2 weeks before: 50% of the agreed fee;

  • less than 2 weeks before, or on the day itself: 100% of the agreed fee.

For multi-day projects, this applies to each affected day.

Preparation already carried out and expenses already committed on your behalf (for example travel or accommodation) are charged in addition, regardless of when you cancel.
If, instead of cancelling, we agree on a new date, I'll gladly credit [part of] any cancellation fee toward the rescheduled booking. Postponing a confirmed date at short notice for a second time is treated as a cancellation. Should I ever have to cancel or reschedule for reasons beyond my control — see Section 5 — no cancellation fee applies to you, and we look for a fair solution together.

2. Confidentiality

I treat everything I see and hear in connection with a project as confidential, and I do not pass information about your organisation, your people, or the process to third parties. Anyone working with me on a project is bound by the same confidentiality. Documents and materials you share with me are returned or deleted on request once the project is complete.

I may discuss my work anonymously with trusted colleagues — for example in supervision, case coaching, or peer consultation — for the purpose of quality assurance and professional development. They are equally bound to confidentiality.

Where a project is clearly outward-facing — for example a public conference with an official hashtag, a published programme, or a public campaign — I take it as agreed that I may mention that I am working with the project and share it on my own channels, in keeping with the tone the project itself sets.

3. Use of results and materials

The methods, materials, and templates I bring into a project remain mine or from colleagues, networks or approaches I work with. Any documentation, visuals, or visual Harvest I create is protected by copyright, which remains with me as the author.

On full payment of the agreed fee, you receive the right to use the agreed results and documentation within your organisation and for the purposes we agreed — for example internal documentation, your website, and social media. Unless we agree otherwise, this right of use is [non-exclusive]; broader or exclusive rights, resale, or substantial editing are agreed separately. As a rule, I make the results available under a Creative Commons licence that we agree on together and note in the offer or on the work itself; where such a licence applies, it governs how you and others may use and share the work.

I retain the right to use results and process photos to present my own work — for example in my portfolio, on my website, and on social media — provided nothing confidential is shown, and unless you object in writing beforehand. Where visual work is published, please credit me as the author (Julia Hoffmann / @juliamosaique).

4. Ending a collaboration early

If, before a project is completed, either of us sees reasons that suggest ending the collaboration early, we commit to a clarifying conversation first. Work already carried out and time already reserved are settled fairly up to that point.

5. Liability

I carry out my work with care and to professional standards. I am liable without limitation for damage caused intentionally or through gross negligence, and for injury to life, body, or health. For slight negligence, I am liable only for the breach of essential contractual obligations, and limited to the foreseeable, typical damage.

I am not responsible for delays or cancellations caused by circumstances beyond my control (for example illness or force majeure). In such cases I will inform you as soon as possible, and we will look for a fair solution together — such as a substitute date, a stand-in, or a revised arrangement.

6. Final provisions

Changes or additions to these principles require written form; an email is sufficient. Should any individual provision be or become invalid, the remaining provisions stay in force. [German law applies. The place of jurisdiction is [Berlin], where legally permissible.]
