Terms of Service
Last updated: 22 August 2026
These terms govern your use of Arvo. They set out what the service does, what it deliberately does not do, and who is responsible for what.
1. Who you are contracting with
Arvo is provided by Arvo Systems Ltd, a company registered in England and Wales, company number 17305187, registered office 48 Norbury Avenue, Watford, England, WD24 4PJ.
By creating an account or using Arvo you accept these terms. If you are accepting on behalf of an organisation, you confirm you are authorised to bind it.
2. The service
Arvo reads construction programmes and contracts together, highlights slipping dates, time bars and events that may warrant a notice, and drafts correspondence aligned to NEC and JCT forms for a person to review.
3. Your account
Keep your credentials secure and tell us promptly if you think an account has been misused. You are responsible for what happens under your account. Access is scoped to the organisations and projects you have been added to, and your organisation’s administrators control that.
4. What Arvo is not
This section is the important one, so it is written plainly rather than in the usual language.
- Arvo is not legal advice and is not a substitute for a solicitor, quantity surveyor, claims consultant or contract administrator. Drafts it produces are starting points for a qualified person to review, amend and decide upon.
- Your contract governs, not our reading of it. Where anything in Arvo conflicts with the executed contract, the contract wins. Always.
- A date shown in Arvo is an aid, not a warranty. Contractual time limits depend on facts we may not hold, including when something was actually communicated and how the parties have conducted themselves. Verify every deadline against the contract before relying on it.
- Nothing leaves Arvo on its own. No notice is issued and no message is sent to a third party without a person choosing to send it.
- AI output can be wrong. Outputs carry provenance so you can see what they were derived from. Check them.
5. Your content
You keep all rights in the programmes, contracts and documents you upload. You grant us a licence to process them only to provide the service to you. We do not use your content to train AI models, and our AI providers are used under API terms that exclude API data from model training.
You are responsible for having the right to upload what you upload, including where it contains someone else’s personal data or is commercially confidential to another party.
6. Acceptable use
- Do not attempt to access another organisation’s data.
- Do not probe, scan or load-test the service without our written permission.
- Do not resell or white-label Arvo without a written agreement.
- Do not upload malware, or content you have no right to hold.
7. Availability and support
We aim to keep Arvo available and will give notice of planned maintenance where we can. Unless a separate written agreement says otherwise, the service is provided without a contractual uptime commitment.
8. Liability
Nothing here limits liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be limited.
Subject to that, and to the extent permitted by law, we are not liable for loss of profit, loss of contract, loss of anticipated savings, or any indirect or consequential loss. Our total liability in any 12 month period is limited to the fees you paid us in that period.
Given section 4, we are not liable for a decision taken on the basis of an Arvo output without professional review, including a missed contractual deadline.
9. Fees, term and ending it
Fees, billing period and notice are set out in your order or subscription. You may stop using Arvo at any time. We may suspend an account for non-payment or for a breach of section 6. On termination you may export your data for 30 days, after which we delete it in line with the Privacy Policy.
10. Changes
We may change these terms. The date at the top changes when we do, and we will give reasonable notice of a material change before it takes effect.
11. Law
These terms are governed by the laws of England and Wales, and its courts have exclusive jurisdiction.
