Terms of service

In effect from 30 July 2026.

1. Parties

These terms form the agreement between Arc (“Arc”, “we”, “us”) and the business or sole trader that opens an account (“you”, “your”). They take effect when you create an account, and they apply for as long as you hold one.

Arc is supplied for business use. By accepting these terms you confirm you are acting for purposes relating to your trade, business or profession. Arc is not sold to consumers.

2. Definitions

  • Service — the Arc application, its interfaces and any feature we make available to you under these terms.
  • Your Content — the conversations, transcripts, decisions, images, contact details and other material you or your Client Recipients put into the Service.
  • Record — the append-only history of decisions and confirmations the Service builds from Your Content.
  • Client Recipient — a person you invite to view and respond to decisions through a client link, without an account.
  • Free Plan — access provided without payment. Paid Plan — access provided in exchange for the fees on the pricing page.

3. What the Service is, and what it is not

Arc records the decisions made between you and your clients, with their provenance, and carries them through a confirmation loop. It is a record-keeping tool.

Arc is not professional advice, a contract, a certification, or construction documentation. Any visual the Service produces is a disposable concept and must never be built from. Professional responsibility for your work, your advice and what you send your clients remains entirely yours.

Decisions are extracted from your conversations by an automated system. It is a drafting aid: you review every decision before it reaches a client, and you are responsible for what you send.

4. Licence

We grant you a non-exclusive, non-transferable, revocable licence to use the Service for your own business for as long as this agreement lasts. You acquire no ownership in the Service. You may not copy, resell, sub-licence, reverse-engineer or rebrand it, or use it to build a competing product.

You must keep your account credentials secure and are responsible for everything done under your account. Tell us promptly if you believe an account or a client link has been compromised.

5. Acceptable use

You must not use the Service to:

  • upload material you have no right to upload, or record a conversation without the consent the law where you operate requires;
  • store special category personal data, payment card numbers, or material subject to sector-specific regulation the Service is not built for;
  • break the law, infringe another party’s rights, or send unsolicited messages;
  • probe, load-test or interfere with the Service or its infrastructure, or attempt to reach data that is not yours;
  • circumvent plan limits, or share one account between people who should hold their own.

Obtaining any consent needed to record a conversation, and to put the people in it into the Service, is your responsibility. Requirements differ by jurisdiction.

6. Your content and the Record

Your Content remains yours. You grant us only the licence needed to run the Service: to store, process, transmit and display Your Content back to you, to your team, and to the Client Recipients you choose. That licence ends when the content is deleted, except for backup copies until they expire on their ordinary cycle.

We do not use Your Content to train artificial intelligence models, and our sub-processors are engaged on terms that do not permit them to either.

The Record is deliberately append-only. A decision that changes is superseded, and both versions remain visible with their dates and sources. This is the point of the product: a record that can be silently edited is not a record.

The Record is shared. It is created by you and confirmed by your client, and both of you may need to rely on it afterwards. Closing your account therefore removes your access, your sign-in and your personal details; it does not erase the project history you and your client built together. Section 12 of the privacy policy explains how this sits with data protection rights.

You can export the Record at any time while your account is open. It is your material and we do not hold it in a format only we can read.

7. Plans, fees and changes

  • Paid Plans are billed monthly in advance and renew automatically until cancelled.
  • Fees exclude VAT, which is added where applicable.
  • You may cancel at any time. Cancellation takes effect at the end of the period you have paid for, and access continues until then.
  • We may change fees on 30 days’ written notice. A change never applies to a period you have already paid for. If you do not accept a change, cancel before it takes effect.
  • Plan limits are stated on the pricing page. Reaching a limit prevents new work of that kind; it never deletes anything already in the Record.
  • If payment fails we may suspend access after reasonable notice. Suspension does not delete the Record.

Refunds are governed by the refunds and cancellation policy, which forms part of this agreement.

The Free Plan is provided as-is and may be changed or withdrawn on reasonable notice. You will always be given the opportunity to export the Record first.

8. Availability and support

We aim to keep the Service available at all times, and we do not offer a contractual uptime guarantee or service credits. Maintenance that we expect to interrupt the Service is notified in advance where practicable.

Support is provided by email at hello@archq.co.uk during UK business hours.

9. Warranties

We warrant that we will provide the Service with reasonable skill and care, and that we have the right to grant the licence in section 4.

Beyond that warranty, and to the extent the law permits, the Service is provided without further warranties, express or implied, including any implied warranty of merchantability or fitness for a particular purpose. We do not warrant that automated extraction is complete or accurate, which is why every decision is presented to you for review before it goes anywhere.

10. Liability

Neither party limits its liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot lawfully be limited.

Subject to that:

  • Neither party is liable for indirect or consequential loss, loss of profit, revenue, goodwill, anticipated savings, or loss arising from business interruption.
  • Our total liability arising out of this agreement is limited to the fees you paid in the twelve months before the claim arose, or £100 where you are on the Free Plan.

You remain responsible for your professional obligations to your own clients. Arc is evidence of what was agreed; it is not a party to your appointment and does not assume your professional liability.

11. Indemnity

You will indemnify us against claims and losses arising from Your Content, from your use of the Service in breach of these terms, and from your failure to obtain a consent that section 5 requires.

12. Intellectual property

The Service, its software, design and documentation belong to us and to our licensors. Your Content and the Record belong to you. Feedback you send us may be used to improve the Service without obligation, and gives us no rights over Your Content.

13. Confidentiality

Each party will keep the other’s confidential information in confidence and use it only to perform this agreement. Your Content is your confidential information. This obligation does not apply to information that is public through no breach, was already held without a duty of confidence, or must be disclosed by law — and where the law allows, we will tell you before disclosing.

14. Data protection

Where we process personal data on your behalf, we do so as your processor under the Data Processing Agreement in Schedule 1, which forms part of these terms. Where we process personal data about you as our customer, we do so as controller, as described in the privacy policy.

15. Suspension and termination

You may close your account at any time from your account settings. We may suspend or terminate access if you materially breach these terms, if your use puts the Service or other customers at risk, or if we are required to by law — and we will tell you why unless the law prevents us.

We may discontinue the Service on 30 days’ notice, during which you may export the Record. If we do so mid-period, we refund the unused portion of any fee paid.

Sections 6, 9, 10, 11, 12, 13 and 18 survive termination.

16. Force majeure

Neither party is liable for a failure to perform caused by an event beyond its reasonable control, for as long as that event continues.

17. General

  • We may update these terms. Material changes are notified by email or in the Service at least 30 days in advance; continuing to use the Service after they take effect means you accept them.
  • You may not transfer this agreement without our consent. We may transfer it to a successor of our business, on notice to you.
  • If a provision is unenforceable, the rest continues in force.
  • A delay in enforcing a right is not a waiver of it.
  • These terms, with the documents they refer to, are the entire agreement between us.
  • There are no third-party beneficiaries: a Client Recipient uses the Service under your account and acquires no rights under this agreement.

18. Governing law

This agreement is governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction. Before starting proceedings, each party will raise the dispute in writing and allow 30 days to resolve it.

Schedule 1 — Data Processing Agreement

This Schedule applies where we process personal data on your behalf. You are the controller; we are the processor. Where it conflicts with the main terms on a data protection matter, this Schedule prevails.

1. Subject matter and duration

We process personal data to provide the Service, for as long as your account is open and for the retention periods in the privacy policy.

2. Nature and purpose of processing

Storing and organising the conversations you import; submitting their text for automated decision extraction; sending client links and notifications; and displaying the Record to you and to your Client Recipients.

3. Categories of data subject and personal data

Data subjects: your personnel, your clients and their representatives, and any individual mentioned in the material you import.

Personal data: names, email addresses, telephone numbers, and whatever personal data appears in the conversations, decisions and images you choose to upload. The Service is not intended for special category data, and you must not upload it.

4. Our obligations

  • Process personal data only on your documented instructions, of which this agreement and your use of the Service are the whole; and tell you if an instruction appears to breach data protection law.
  • Ensure personnel with access are bound by confidentiality.
  • Apply appropriate technical and organisational measures, described on the security page.
  • Assist you, so far as reasonably possible, with data subject requests, security obligations, breach notification and impact assessments.
  • Notify you without undue delay, and in any event within 72 hours, on becoming aware of a personal data breach affecting your data.
  • On termination, delete or return personal data as described in section 9 below.

5. Your obligations

  • Ensure you have a lawful basis for the personal data you put into the Service, including any consent required to record a conversation.
  • Provide the privacy information your own data subjects are entitled to.
  • Send client links only to the intended recipient. A client link is a bearer link, and anyone holding it can see the decisions it covers.

6. Sub-processors

You give general authorisation for the sub-processors listed below. We impose data protection obligations on each that are no less protective than this Schedule, and we remain liable for their performance. We will give at least 30 days’ notice before adding or replacing one, and you may object on reasonable data protection grounds; if we cannot resolve the objection, you may terminate and receive a refund of the unused portion of any fee paid.

  • Amazon Web Services — Hosting, database and file storage. Processes in United Kingdom.
  • Anthropic — Reads the conversations you import in order to extract decisions. Processes in United States.
  • Resend — Delivers the emails Arc sends on your behalf. Processes in European Union.
  • Stripe — Subscription billing. Card details are entered with Stripe and never reach Arc. Processes in European Union and United States.
  • Amplitude — Product analytics, only where you have consented. Processes in European Union.

7. International transfers

Personal data is stored in the United Kingdom. Where a sub-processor processes it outside the UK, that transfer is made under the UK International Data Transfer Addendum to the EU Standard Contractual Clauses, or under UK adequacy regulations where they apply.

8. Audit

On reasonable written request, and no more than once a year unless a breach or a regulator requires otherwise, we will provide the information reasonably necessary to demonstrate compliance with this Schedule.

9. Deletion and return

On termination we delete your account, your personal details and your access. As set out in section 6 of the main terms, the shared Record is retained because it is not solely yours to erase — see section 12 of the privacy policy, which explains the basis for that and what you can still ask for. You may export the Record before closing your account, and we will assist you with an export afterwards on request.

10. Governing law

This Schedule is governed by the law of England and Wales.
