To use the Platform you must create an account with a valid email address and password. You are responsible for:
- Keeping your login credentials secure and confidential
- All activity that occurs under your account, including activity by Users you add to your workspace
- Notifying us immediately at [email protected] if you become aware of any unauthorised access to your account
You must not share your account credentials with third parties outside your organisation. Each workspace may have any number of Users under a single Subscription at no additional per-seat charge.
4. Subscription, payment and billing
4.1 Plans and fees
Preface offers three Subscription tiers — Starter, Growth, and Scale — with fees as published on the Preface pricing page at the time of your subscription. Prices are quoted excluding VAT where applicable. VAT will be added at the applicable rate at the point of billing.
4.2 Billing cycle
Subscriptions are billed monthly or annually in advance, according to the billing cycle you selected at sign-up. Annual subscriptions are billed as a single upfront payment.
4.3 Payment
Payment is processed by our third-party payment provider. By providing payment details, you authorise us to charge your payment method at the start of each billing period. If a payment fails, we will notify you and may suspend your account until payment is received.
4.4 Price changes
We may change Subscription prices by giving you at least 30 days' written notice by email. Price changes take effect at your next renewal date following the notice period. If you do not accept the new price, you may cancel your Subscription before the renewal date.
4.5 Refunds
Subscription fees are non-refundable except where required by applicable law. If you cancel a monthly Subscription, you retain access until the end of the current billing period. If you cancel an annual Subscription, no pro-rated refund is provided for any unused portion of the annual term, except where required by law.
4.6 Add-ons
Add-ons (such as extra lead volume or additional workspaces) are billed monthly in addition to your Subscription fee, regardless of your base billing cycle.
5. Free trial
We may offer a free trial period of up to 14 days. During the trial you will have access to all features of the plan tier selected. No payment is required to start a trial.
At the end of the trial period, you must enter payment details to continue using the Platform. If you do not, your account will be restricted to read-only access and any published Demos will be taken offline until a Subscription is activated.
We reserve the right to modify or discontinue free trial offers at any time.
6. Permitted use
Subject to these Terms and payment of the applicable fees, we grant you a limited, non-exclusive, non-transferable licence to access and use the Platform during your Subscription for your internal business purposes — specifically, to create, publish, and share product Demos.
This licence permits you to:
- Install and use the Preface Chrome extension on devices you control
- Capture screenshots of software interfaces you are authorised to access
- Create and publish Demos using the Platform builder
- Share Demo links with third parties (Viewers) for commercial and marketing purposes
- Use the API and webhooks within the rate limits set by your plan
7. Prohibited use
You must not use the Platform to:
- Capture screenshots of software, websites, or content that you do not have the right to reproduce or share
- Create Demos containing content that is unlawful, defamatory, obscene, or infringes the intellectual property rights of any third party
- Engage in spamming or unsolicited contact with Viewers whose data you have captured via gate forms
- Attempt to reverse engineer, decompile, or extract source code from any part of the Platform
- Use automated means (bots, scrapers, crawlers) to access the Platform or its APIs in ways that exceed your plan limits or that we have not expressly permitted
- Resell, sublicence, or commercially exploit access to the Platform to third parties without our prior written consent
- Use the Platform in any way that imposes an unreasonable or disproportionate load on our infrastructure
- Introduce malware, viruses, or other harmful code into the Platform or its delivery infrastructure
- Impersonate any person or entity or misrepresent your affiliation with any person or entity
We reserve the right to investigate suspected violations and to suspend or terminate accounts where we find a breach of this section.
8. Your content
You retain all ownership of the Content you upload to or create within the Platform. By using the Platform, you grant DevLayer Ltd a limited, non-exclusive licence to store, process, host, and deliver your Content solely for the purpose of providing the service to you and your Viewers.
We do not claim any ownership over your Content. We will not use your Content for our own marketing, AI training, or any purpose other than providing the Platform services, without your explicit consent.
You represent and warrant that:

- Your Content does not infringe the intellectual property rights, privacy rights, or other legal rights of any third party

9. Intellectual property
The Platform, including all software, design, trademarks, and documentation, is the exclusive property of DevLayer Ltd or its licensors. Nothing in these Terms transfers any ownership of our intellectual property to you.
The name "Preface", the Preface logo, and all associated branding are trademarks of DevLayer Ltd. You must not use them without our prior written consent.
10. Third-party integrations
The Platform integrates with third-party services including ElevenLabs (voiceover generation), CRM platforms, and others. Your use of these integrations is subject to the third parties' own terms of service. We are not responsible for the availability, accuracy, or conduct of third-party services.
If you configure your own API keys for third-party integrations within your Preface workspace settings, you are responsible for compliance with those third parties' usage policies.
11. Service availability
We aim to maintain high availability of the Platform but do not guarantee uninterrupted service. Planned maintenance will be communicated in advance where practicable. We are not liable for any loss resulting from downtime, whether planned or unplanned.
Scale plan customers with SLA-backed support terms receive uptime commitments as set out in their order confirmation. No SLA applies to Starter or Growth plans.
12. Suspension and termination
12.1 Termination by you
You may cancel your Subscription at any time through the account settings in the Platform. Cancellation takes effect at the end of the current billing period. You remain responsible for all fees accrued up to the cancellation date.
12.2 Termination by us
We may suspend or terminate your account with immediate effect if:
- You breach these Terms and fail to remedy the breach within 7 days of written notice
- You fail to pay fees when due and do not remedy the payment failure within 14 days
- We are required to do so by law or court order
- You engage in conduct that we reasonably believe poses a risk to the security or integrity of the Platform or to other customers
We may also terminate the Platform with 30 days' notice for any reason. In this case, we will refund any prepaid fees for the unused portion of your Subscription.
12.3 Effect of termination
On termination, your access to the Platform will cease. Your Content will be retained for 30 days, during which you may request an export. After 30 days, your Content will be permanently deleted.

- We are not liable for loss or damage arising from your reliance on the accuracy of AI-generated annotation suggestions, voiceover content, or any other AI-assisted output from the Platform
Nothing in these Terms limits our liability for death or personal injury caused by our negligence, fraud or fraudulent misrepresentation, or any other liability that cannot be excluded under English law.
14. Warranties
The Platform is provided "as is" and "as available". To the fullest extent permitted by applicable law, we disclaim all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, and non-infringement.
We do not warrant that the Platform will meet your specific requirements, that it will be error-free, or that any defects will be corrected within a particular timeframe.
Nothing in this section affects any statutory rights you may have as a consumer under applicable law.
