1. Scope and applicability

1.1

These General Terms and Conditions (“GTC”) govern all contractual relationships between Halderstone and its clients (“Client”) relating to advisory services, training courses, educational programs, workshops, and any related services or deliverables (collectively, the “Services”), unless explicitly agreed otherwise in writing.

1.2

The GTC form an integral part of all offers, proposals, order confirmations, service agreements, and contracts concluded between Halderstone and the Client. By accepting an offer, placing an order, booking a training, or otherwise engaging Halderstone’s Services, the Client confirms acceptance of these GTC.

1.3

Individual agreements, statements of work, course descriptions, or written contractual arrangements concluded between Halderstone and the Client shall prevail over these GTC to the extent of any explicit inconsistency. Deviations from these GTC are valid only if expressly agreed in writing.

1.4

Any general terms and conditions of the Client shall not apply, even if Halderstone does not expressly object to them. Such terms shall apply only if Halderstone has explicitly accepted them in writing.

1.5

These GTC apply to contractual relationships with both business clients and private individuals. Where the Client qualifies as a consumer within the meaning of applicable mandatory consumer protection law, such mandatory provisions shall remain unaffected.

1.6

Halderstone reserves the right to amend these GTC at any time. The version valid at the time of conclusion of the contract shall apply, unless a later version is explicitly declared applicable by Halderstone and accepted by the Client.

2. Definitions

For the purposes of these General Terms and Conditions (“GTC”), the following terms shall have the meanings set out below:

2.1

Client: Any natural person or legal entity that enters into a contractual relationship with Halderstone for the provision of Services.

2.2

Halderstone: The business name and brand under which Langer & Co, a company organised under the laws of Switzerland, provides the Services. Where these GTC or any contract refer to “Halderstone”, such reference shall be understood as a reference to Langer & Co as the legal contracting party.

2.3

Services: All advisory services, training courses, educational programs, workshops, and related services provided by Halderstone, as specified in individual agreements, course descriptions, offers, or order confirmations.

2.4

Training: Any training course, module, track, workshop, seminar, or educational program offered by Halderstone, whether delivered in person, online, or in a hybrid format.

Advisory Services: Professional consulting, advisory, or support services provided by Halderstone, including but not limited to strategy, governance, management systems, compliance, risk management, and related topics.

2.6

Materials: All documents, presentations, training materials, methodologies, templates, tools, recordings, and other content provided or made available by Halderstone in connection with the Services, irrespective of the form or medium.

2.7

Written Form: Form requiring a declaration to be made in writing or in another form evidencing text, including email, unless a stricter form requirement is explicitly agreed.

3. Conclusion of contract

3.1

Offers, proposals, course descriptions, and price information issued by Halderstone are non-binding unless expressly designated as binding.

Certificates of completion or diplomas may be issued for Training programs or tracks that include defined assessment elements, such as examinations or capstone projects, and confirm successful completion based on the applicable evaluation criteria.

Unless expressly stated otherwise, any confirmations, certificates, or diplomas issued attest achievement or participation within the respective Halderstone program only and do not constitute a state-recognised qualification nor guarantee regulatory, professional, or third-party accreditation.
