By accessing or using the Delta Forge platform, website, APIs, or any associated services (collectively, the "Service"), you agree to be bound by these Terms.
If you are entering into these Terms on behalf of an organisation, you represent and warrant that you have the authority to bind that organisation, and references to "you" shall include that organisation.
If you do not agree to these Terms, you must not access or use the Service.

Subscriptions are subject to fair use limits. We reserve the right to throttle or suspend access in the event of usage that materially exceeds the parameters of your Subscription tier, after providing reasonable notice.
Fees for the Service are as set out in your Subscription or order form. All fees are quoted exclusive of VAT and applicable taxes, which shall be added where required by law.
Subscription fees are billed in advance on a monthly or annual basis, as selected at the time of purchase. Payment is due within 30 days of invoice date. We reserve the right to suspend access to the Service for overdue payments exceeding 14 days past the due date.
Certain components of the Service may be billed on a consumption basis measured in DFCU. Metered charges are calculated based on queries executed, data processed, and compute resources consumed, and are invoiced monthly in arrears.
We may adjust pricing upon 30 days' written notice prior to the start of a new billing period. Continued use of the Service after a price change constitutes acceptance of the new pricing.
You retain all rights, title, and interest in your Customer Data. We do not claim any ownership of Customer Data.
You grant us a limited, non-exclusive licence to host, store, transfer, display, and process your Customer Data solely to the extent necessary to provide and improve the Service in accordance with these Terms and our Privacy Policy.

Upon termination of your Subscription, we will make your Customer Data available for export for a period of 30 days. After this period, we will delete your Customer Data from our active systems. Copies may be retained in encrypted backups for a further period not exceeding 90 days, after which they will be permanently deleted.
Where you use the Service to process personal data of your own data subjects, you are the data controller and we are the data processor. The terms of this Section 7 constitute the Data Processing Agreement ("DPA") between us in accordance with Article 28 of UK GDPR and EU GDPR.
We shall process personal data only on your documented instructions, including with regard to transfers of personal data to a third country, unless required to do so by applicable law, in which case we shall inform you of that legal requirement before processing (unless the law prohibits such notification).
We shall ensure that persons authorised to process personal data have committed themselves to confidentiality or are under an appropriate statutory obligation of confidentiality.
We shall implement appropriate technical and organisational measures to ensure a level of security appropriate to the risk, including:
You provide general authorisation for us to engage sub-processors. We shall inform you of any intended changes concerning the addition or replacement of sub-processors, giving you the opportunity to object. Our current sub-processors are listed in our Privacy Policy.
We shall assist you, by appropriate technical and organisational measures and insofar as this is possible, in fulfilling your obligation to respond to requests for exercising data subjects' rights under Chapter III of the GDPR.
We shall notify you without undue delay (and in any event within 72 hours) after becoming aware of a personal data breach affecting Customer Data. The notification shall include the nature of the breach, the categories and approximate number of data subjects and records concerned, likely consequences, and measures taken or proposed to address the breach.
We shall make available to you all information necessary to demonstrate compliance with this DPA and allow for and contribute to audits, including inspections, conducted by you or an auditor mandated by you, subject to reasonable notice and confidentiality obligations.
Upon termination of the Service, we shall, at your choice, delete or return all personal data processed on your behalf and delete existing copies, unless applicable law requires retention.

If you provide us with feedback, suggestions, or ideas regarding the Service, you grant us a perpetual, irrevocable, royalty-free, worldwide licence to use such feedback for any purpose without obligation to you.
Each party agrees to keep confidential all non-public information disclosed by the other party that is designated as confidential or that a reasonable person would consider confidential ("Confidential Information"). Neither party shall disclose the other's Confidential Information to any third party except as necessary to perform its obligations under these Terms and subject to appropriate confidentiality undertakings.
This obligation shall not apply to information that: (a) is or becomes publicly available through no fault of the receiving party; (b) was known to the receiving party prior to disclosure; (c) is independently developed without reference to the disclosing party's Confidential Information; or (d) is required to be disclosed by law or regulation.
Each party represents and warrants that it has the legal power and authority to enter into these Terms.

EXCEPT AS EXPRESSLY SET OUT IN THESE TERMS, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE". TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE DISCLAIM ALL OTHER WARRANTIES, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, NEITHER PARTY SHALL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS OPPORTUNITY, HOWEVER CAUSED, WHETHER IN CONTRACT, TORT, OR OTHERWISE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
EXCEPT FOR LIABILITY ARISING FROM BREACHES OF SECTION 10 (CONFIDENTIALITY) OR YOUR PAYMENT OBLIGATIONS, EACH PARTY'S TOTAL AGGREGATE LIABILITY UNDER THESE TERMS SHALL NOT EXCEED THE TOTAL FEES PAID OR PAYABLE BY YOU IN THE 12-MONTH PERIOD IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM.
Nothing in these Terms shall exclude or limit liability for: (a) death or personal injury caused by negligence; (b) fraud or fraudulent misrepresentation; (c) any liability that cannot be excluded or limited by applicable law.

You shall defend, indemnify, and hold us harmless from and against any third-party claim arising from: (a) your breach of these Terms; (b) your Customer Data; or (c) your use of the Service in violation of applicable law.
These Terms are effective from the date you first access the Service and continue for the duration of your Subscription. Subscriptions renew automatically unless cancelled in accordance with these Terms.
You may cancel your Subscription at any time through your account settings. Cancellation will take effect at the end of the current billing period. No refunds are provided for unused portions of a billing period.

These Terms are governed by and construed in accordance with the laws of England and Wales. The parties submit to the exclusive jurisdiction of the courts of England and Wales for the resolution of any disputes arising under or in connection with these Terms.
These Terms, together with any applicable order form and our Privacy Policy, constitute the entire agreement between the parties with respect to the subject matter hereof and supersede all prior agreements, understandings, and representations.
We may amend these Terms by providing 30 days' notice via email or through the Service. Your continued use of the Service after the effective date of such amendment constitutes acceptance. If you do not agree with a material amendment, you may terminate your Subscription before the amendment takes effect.
If any provision of these Terms is held to be invalid or unenforceable, the remaining provisions shall continue in full force and effect.
The failure of either party to enforce any right or provision of these Terms shall not constitute a waiver of that right or provision.
You may not assign or transfer these Terms or any rights hereunder without our prior written consent. We may assign these Terms in connection with a merger, acquisition, or sale of all or substantially all of our assets.
Neither party shall be liable for any delay or failure to perform its obligations (other than payment obligations) where such delay or failure results from circumstances beyond its reasonable control, including but not limited to acts of God, natural disasters, pandemics, government actions, war, terrorism, power failures, or internet service disruptions.
