Terms of Service

D4 Digital OS is a business-management platform for surfacing and home-improvement contractors: pricing and quoting, AI visualisation, CRM, e-signed sales orders and contracts, job and crew management, scheduling, invoicing and related tools. Features may be added, changed or retired over time; we will not materially reduce the core Service you pay for during a paid period without notice.

• You must provide accurate information and keep your login credentials secure. You are responsible for activity under your account.
• The Service is organised around organisations. The organisation owner controls membership, roles and billing, and is responsible for the people they invite.
• You must be at least 18 and using the Service for business purposes.

• Subscriptions are billed per organisation, monthly in advance, through our payment provider Stripe. We do not store your card details.
• Where a free trial is offered, the card on file is charged when the trial ends unless you cancel before then.
• You can cancel at any time (subject to any minimum term in a separate written agreement); access continues until the end of the paid period. Fees already paid are non-refundable except where the law says otherwise.
• If payment fails we may retry and, after a grace period, suspend access until payment succeeds. Your data is not deleted because of a failed payment.
• We may change pricing with at least 30 days’ notice; changes apply from your next billing period. Price promises in a signed agreement (e.g. founder pricing) are honoured.

• Everything your organisation puts into the Service — customers, quotes, photos, documents, prices — belongs to your organisation.
• You grant us the limited licence needed to host, process, back up and display that content in order to run the Service. We do not sell your data and we do not use your customer data to train AI models.
• You can request an export of your organisation’s data at any time via support.
• You are responsible for having a lawful basis to enter your customers’ personal data into the Service. We process it on your behalf as described in the Data Processing Addendum.

See our Privacy Policy and Data Processing Addendum for how data is handled.

You agree not to:

• break the law, infringe others’ rights, or send spam or unlawful marketing through the Service;
• upload malicious code, attempt to gain unauthorised access, or probe or disrupt the Service or other organisations’ data;
• resell, sublicense or white-label the Service without our written agreement;
• use automated means to extract data at scale other than the export tools we provide.

We may suspend accounts that put the Service or other customers at risk, and will tell you why.

AI-generated output (for example driveway visualisations, drafted text and call summaries) is produced by machine-learning models and is illustrative, not a promise of a finished result, a survey, or professional advice. You are responsible for reviewing AI output before relying on it or sending it to a customer. AI usage may be subject to fair-use limits on your plan.

We aim to keep the Service available at all times but do not guarantee uninterrupted operation; maintenance, third-party outages and events outside our control can cause downtime. Support is provided by email at support@d4digitalos.com — we respond as quickly as we can during UK business hours.

The Service, its software, design and branding remain the property of D4 and its licensors. Feedback you give us about the Service may be used to improve it without obligation to you.

• Nothing in these terms excludes liability that cannot be excluded under the law of England and Wales (including for death or personal injury caused by negligence, or fraud).
• Subject to that, we are not liable for indirect or consequential loss, loss of profit, or loss of data caused by events outside our reasonable control.
• Our total liability arising out of the Service in any 12-month period is capped at the fees your organisation paid us in that period.
• The Service supports your business decisions (pricing, quoting, scheduling) but does not make them — you remain responsible for the prices you quote, the contracts you sign and the work you deliver.

• You may stop using the Service and cancel your subscription at any time.
• We may terminate or suspend access for material breach of these terms that is not fixed within 14 days of notice, or immediately for serious misuse.
• After termination we keep your organisation’s data for 90 days so you can export it, then delete it in the ordinary course, except where the law requires longer retention.

We may update these terms from time to time. For material changes we will give at least 30 days' notice by email or in-app. Continuing to use the Service after a change takes effect means you accept it.

These terms are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction. Questions? Contact support@d4digitalos.com.
