8.1 Disclaimer

TJ-Tronics provides the Services and Platform on an "as is" and "as available" basis. Except as expressly set forth as "Warranty" in this Agreement and to the fullest extent permitted by law, TJ-Tronics makes no warranties and statutory warranties, express and implied, with respect to its performance under this Agreement, the Services, the Technology, the Data and the Documentation, including with respect to availability, the implied warranties of fitness for a particular purpose, merchantability and non-infringement, and the implied warranties arising from course of dealing, performance or usage of trade, and expressly disclaims all such warranties.

8.2 Limitations of Liability

To the extent permitted by law, TJ-Tronics will not be liable to any user with respect to this Agreement or the Services during or after the Term for any lost profits, personal injury, property damage, loss of data, business interruption, indirect, incidental, consequential, exemplary, special, reliance or punitive damages, even if such losses, damages or costs are foreseeable and whether or not the user or TJ-Tronics was advised of their possibility.

To the extent permitted by law, TJ-Tronics shall not be liable to any user for any loss, damage or expense in relation to this Agreement or the Services during or after the Term (whether in contract, negligence, strict liability or tort or under any other legal or other theory).

9. Choice of law and place of jurisdiction

  1. These General Terms and Conditions and the contractual relationship between TJ-Tronics and the user are subject to the law of the Federal Republic of Germany, excluding international uniform law, in particular the UN Convention on Contracts for the International Sale of Goods.
  2. If the user is a merchant within the meaning of the German Commercial Code, a legal entity under public law or a special fund under public law, our place of business in Heiligenhaus is the exclusive and international place of jurisdiction for all disputes arising directly or indirectly from the contractual relationship. The same applies if the buyer is an entrepreneur within the meaning of Section 14 of the German Civil Code.
  3. We are also entitled to file a lawsuit at the place of performance of the delivery obligation in accordance with these General Terms and Conditions or a prior individual agreement or at the general place of jurisdiction of the buyer. Priority statutory provisions (exclusive places of jurisdiction) remain unaffected by this.

10. Final provision

  1. TJ-Tronics is entitled to transfer its rights and obligations arising from this contractual relationship in whole or in part to a third party with a notice period of four weeks. In this case, the user also has the right to terminate the contract at any time without notice and free of charge.
  2. TJ-Tronics can propose a change to these General Terms and Conditions to the user at any time in text form (e.g. by email) with a lead time of at least 30 days before the proposed date of their entry into force. The change offered to the user only comes into force if the user agrees to the changes. In the case of a significant change, the user agrees to it with express consent; in the case of an insignificant change, consent is deemed to have been given unless rejected in text form to TJ-Tronics before the proposed date of entry into force. Changes are then significant if they significantly change the previously agreed relationship between performance and consideration to the detriment of the user or are equivalent to the conclusion of a completely new contract. A change resulting from a change in the law, a legally binding court judgment or an interim injunction does not constitute a significant change.
  3. Should individual provisions of these General Terms and Conditions be or become invalid or ineffective in whole or in part, this shall not affect the validity of the remaining provisions.
  4. All declarations transmitted within the framework of the user agreement concluded with TJ-Tronics must be made in writing or text form (e.g. by email).
