1.4 Swiss law shall apply exclusively, in particular the Swiss Code of Obligations (OR), excluding the UN Convention on Contracts for the International Sale of Goods (CISG) and private international law.

2 Contract Formation and Online Orders

2.1 Offers from the Provider are non-binding and subject to change, unless expressly stated otherwise or a binding period is specified.

3 Scope of Services

3.1 The type and scope of services are conclusively determined by the written offer, service description or specifications. Services not expressly agreed upon are not subject matter of the contract.

3.2 Changes, extensions or reductions to the scope of services (change requests) require a separate written agreement and may result in adjustments to deadlines, prices and conditions.

3.3 The Provider is entitled to use subcontractors, third parties or AI-powered systems to fulfil its contractual obligations. Responsibility towards the Client remains with the Provider.

3.4 The Provider owes professional service provision according to the state of the art. A specific economic success or specific results are not owed unless expressly agreed.
