1.1. The customer acquires from WINGFIELD the hardware specified in the contract with the associated tracking software and the associated documentation or product description (together “delivery items”) under the conditions regulated herein.
1.2. The source code of the tracking software is not part of the delivery.
1.3. The performance description contained in the documentation or product description (also in audiovisual form) is conclusively decisive for the quality of the delivery items supplied by WINGFIELD. WINGFIELD does not owe any further quality of the delivery items. In particular, the customer cannot derive such an obligation from other representations of the delivery items in public statements or in advertising by WINGFIELD and/or the manufacturer, as well as their employees or sales partners, unless WINGFIELD has expressly confirmed the additional quality in writing. Since the use of the delivery items is dependent on a functioning Internet connection, WINGFIELD cannot always guarantee a specific upload speed or uninterrupted use of the delivery items for technical reasons. Furthermore, the service is temporarily limited if this is necessary with regard to capacity limits, the security or integrity of the servers or for the implementation of technical measures and this serves the proper or improved provision of the services (in particular maintenance work).

3.4. Duplication or reworking of the documentation is not permitted.
4. Software protection
4.1.

6.4. The time at which WINGFIELD hands over the delivery items to the carrier is decisive for compliance with delivery dates and the transfer of risk in the case of physical shipment; in the case of software, the time at which the software is made available for retrieval is decisive.
7. Defects of quality and title, other defects in performance, limitation period
7.1. WINGFIELD warrants the agreed quality of the delivery items in accordance with Clause B.I.1.3. and that the use of the delivery items by the customer to the extent stipulated in the contract does not conflict with any rights of third parties.
7.2. In the event of material defects, WINGFIELD shall initially provide warranty by means of subsequent performance. For this purpose, it shall, at its discretion, provide the customer with a new, defect-free delivery item or rectify the defect; rectification of the defect shall also be deemed to be if WINGFIELD shows the customer reasonable possibilities of avoiding the effects of the defect.
7.3. If a third party claims the infringement of property rights against the customer due to the use of the delivery items, the customer shall inform WINGFIELD of this immediately and leave the defence against these claims to WINGFIELD as far as possible. In doing so, the customer will provide WINGFIELD with all reasonable support. In particular, the customer shall provide all necessary information on the use and possible processing of the delivery items, if possible in writing, and provide the necessary documentation. If it is legally established that the delivery items infringe the industrial property rights of third parties, WINGFIELD may, at its discretion, remedy the infringement by

If the subsequent order also fails within the grace period, the customer may reduce the remuneration or withdraw from the contract. Withdrawal is not permissible in the case of an insignificant defect. WINGFIELD will pay compensation or reimbursement of futile expenses due to a defect within the limits set out in Clause B.I.8. After the expiry of a deadline set in accordance with sentence 1, WINGFIELD can demand that the customer exercise his rights resulting from the expiry of the deadline within two weeks after receipt of the request.
7.6. The customer can only derive rights from other breaches of duty by WINGFIELD if he has notified WINGFIELD of these in writing and has granted WINGFIELD a period of grace to remedy the situation. This does not apply if a remedy is not possible due to the nature of the breach of duty. The limits set out in section B.I.8. apply to compensation for damages or futile expenses.
7.7. The limitation period for all warranty claims is based on the statutory framework conditions, unless otherwise contractually agreed. In the event of intent or gross negligence on the part of WINGFIELD in the case of fraudulent concealment of the defect, in the case of personal injury or defects of title within the meaning of § 438 Para. 1 No. 1 a BGB (German Civil Code), as well as in the case of guarantees (§ 444 BGB), the statutory limitation periods shall apply, as shall claims under the Product Liability Act.
8.1. In all cases of contractual and non-contractual liability, WINGFIELD shall pay damages exclusively in accordance with the following limits:
(i) in the event of intent and gross negligence in the full amount, as well as in the absence of a quality for which WINGFIELD has assumed a guarantee;
(ii) in other cases: only for breach of a material contractual obligation (“cardinal obligation”), if the purpose of the contract is thereby jeopardised, but always only to the extent of the foreseeable damage. Liability for other consequential damage and loss of profit is excluded. For a single case of damage, the liability per case of damage is limited to the purchase price. The term “cardinal obligation” refers in the abstract to obligations whose fulfilment is essential for the proper performance of the contract and on whose fulfilment the contractual partner may regularly rely.
8.2. The limitations of liability pursuant to clause B.I.8.1. shall not apply in the case of liability for personal injury and in the case of liability under the Product Liability Act.
8.3. WINGFIELD is free to raise the objection of contributory negligence.
8.4. Clause B.I.7.7. shall apply mutatis mutandis to the limitation period, with the proviso that the statutory limitation period shall apply to claims under Clauses B.I.8.1(i) and B.I.8.2. The limitation period pursuant to sentence 1 shall commence at the point in time specified in § 199 section 1 of the German Civil Code (BGB). It shall commence at the latest upon expiry of the maximum periods stipulated in § 199 para. 3 and para. 4 BGB.

The type and method of remedying the defect are at the reasonable discretion of WINGFIELD.

New programme parts can eliminate errors in previous versions and/or change and/or improve existing functions or contain new functions. However, the delivery of new programme parts does not include in particular (i) separately offered additional functions of the software; (ii) a new development of the software with the same or similar functions on a different technological basis. These new versions of the software can be acquired against additional remuneration within the framework of separate agreements.
5.2. B.II.2.3. shall apply accordingly to the delivery of programme parts.
