Terms of Service — PFD Bench (Trial)

Last updated: 2026-07-09

These Terms of Service ("Terms") govern the use of the PFD Bench trial service (the "Service"), operated by:

lyfX.ai UG (haftungsbeschränkt) Am Tiemen 12, 58452 Witten, Germany Email: info@lyfx.ai Commercial register: HRB 21430 (Amtsgericht Bochum)

By creating an account or using the Service, you accept these Terms. If you do not agree, do not use the Service.

1. The Service

PFD Bench is an experimental, AI-assisted tool that analyzes process engineering drawings (PFDs and P&IDs) uploaded as DXF files and generates equipment tables, instrument tables and process descriptions. The Service is provided as a free, time- and volume-limited trial for evaluation purposes only. It is intended for professional users in a business context (B2B); it is not directed at consumers.

2. Trial character, availability, changes

The Service is a trial of pre-release software. We may modify, limit, suspend or discontinue the Service (in whole or in part) at any time without notice, and we may change these Terms for future use. Accounts include a limited number of analysis runs; we may change limits, extend them on request, or decline to do so, at our discretion. We do not guarantee any availability, response time, or continued existence of the Service or of any data within it.

3. Your account and acceptable use

  • You must register with a valid business email address and provide accurate information.
  • You are responsible for keeping your credentials confidential and for all activity under your account.
  • You may not: misuse the Service (including attempts to circumvent trial limits, probe or disrupt the Service, or access other users' data); use automated means to mass-create accounts or submissions; reverse engineer the Service except where mandatory law permits it.

4. AI-generated output — no engineering advice, verification required

The Service's outputs are generated by artificial-intelligence systems and may be incomplete, inaccurate or wrong — including in ways that are not obvious. The outputs:

  • are provided for evaluation and informational purposes only;
  • are not engineering advice, not a design deliverable, and not a substitute for review by a qualified professional engineer;
  • must be independently verified against the original drawing and applicable standards before any use, and must never be used as the sole basis for any engineering, design, procurement, safety or operational decision.

You remain solely responsible for any decision or action taken on the basis of the Service's outputs.

5. Your content

  • You retain all rights to the drawings and files you upload ("Your Content").
  • You warrant that you have all rights and permissions necessary to upload Your Content and to have it processed by the Service, and that doing so does not violate any law, contract or third-party right (including your employer's or client's confidentiality obligations).
  • You grant us a non-exclusive, limited license to process Your Content solely to provide the Service to you.
  • Processing involves transmitting extracted drawing data to third-party AI providers (currently OpenAI and Google) as sub-processors. Do not upload content you are not permitted to share with such providers.
  • Your Content is not used to train AI models — neither by us nor, under the API terms applicable to our use, by our AI providers.
  • Trial content (uploaded files, extracted tables, generated descriptions) is automatically and irreversibly deleted 24 hours after each run; you can also delete it immediately at any time. Deletion is permanent — we keep no copies and cannot restore deleted content. Details in the Privacy Policy.

6. Feedback

If you submit feedback (ratings, comments, suggestions), we may use it without restriction or compensation to improve our products. Feedback must not contain confidential information.

7. Our intellectual property

The Service, including its software, models, prompts, design and documentation, remains our (or our licensors') property. These Terms grant you no rights in it beyond the limited right to use the Service during the trial.

8. Warranty disclaimer

The Service is provided "as is" and "as available", free of charge, for trial purposes. To the extent permitted by law, we make no warranties or representations of any kind — express or implied — including as to merchantability, fitness for a particular purpose, accuracy, completeness, availability or non-infringement. Statements about the Service's capabilities are descriptions of experimental functionality, not guaranteed characteristics (keine Beschaffenheitsgarantie).

9. Limitation of liability

  1. To the maximum extent permitted by law, we accept no liability for any damages arising out of or in connection with the Service or these Terms — including, without limitation, loss of profits, business interruption, loss of data, and the consequences of decisions taken on the basis of the Service's outputs (see §4). The Service is free of charge and experimental; you use it at your own risk.
  2. Where liability cannot be excluded under mandatory law, it is limited — in cases of simple negligence — to breaches of essential contractual duties (Kardinalpflichten) and, in amount, to the damage that is typical and foreseeable for a free trial service of this kind.
  3. Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law.
  4. The above applies equally in favour of our legal representatives, employees and agents.

10. Indemnity

You will indemnify us against third-party claims arising from Your Content or from your use of the Service in breach of these Terms (including reasonable legal costs), unless you are not responsible for the breach.

11. Termination

You may stop using the Service and request account deletion at any time (info@lyfx.ai). We may suspend or terminate accounts that breach these Terms or abuse the trial, and may discontinue the trial as per §2.

12. Final provisions

  • These Terms are governed by German law, excluding the UN Convention on Contracts for the International Sale of Goods (CISG).
  • Exclusive place of jurisdiction is Bochum.
  • If any provision of these Terms is or becomes invalid, the remaining provisions remain unaffected.
  • Mandatory information under Regulation (EU) No 524/2013: the European Commission provides an Online Dispute Resolution platform at https://ec.europa.eu/consumers/odr/. We are neither obliged nor willing to participate in dispute resolution proceedings before a consumer arbitration board.
