These Terms govern your access to and use of BusinessOS, a product of Nexus Data & AI Limited, a company registered in England and Wales under company number 17066175 ("Nexus", "we", "us"). By using the Services you agree to these Terms, which form an agreement between you and Nexus.
The Services
BusinessOS provides a unified workspace for email, contacts, calendar, tasks, and proposals, with AI-assisted features. You can reach it through the web app, through our apps for iPhone and Android, and through the interfaces we publish for connecting other software to your workspace. If you add a website, we also register a domain name for you and host your website on it. We may modify or discontinue features with reasonable notice.
Account responsibilities
You are responsible for safeguarding your account credentials, for all activity under your account, and for ensuring that all users in your workspace comply with these Terms.
Acceptable use
- No use that violates applicable law.
- No abuse, reverse engineering, or attempts to circumvent rate limits.
- No sending of unsolicited bulk communications via the Services.
- Nothing on a website we host for you that is unlawful, infringes anyone's rights, misleads visitors about who you are or what you offer, or puts visitors at risk, for example by collecting their details under false pretences.
These rules cover what you publish through the Services as well as how you use them, including the words, pictures and links on a website we host for you.
The apps for iPhone and Android
We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the BusinessOS app on devices you own or control, for as long as you have an account. You may not copy, modify, distribute, sell, or lease the app, or attempt to derive its source code.
The app is a way into your workspace rather than a separate product. It needs an account, and everything in these Terms about your account, acceptable use and Your Data applies to it unchanged.
Installing the app also puts you under the terms and usage rules of the store you installed it from. Those are between you and Apple or Google, they can govern your use of the app as well as the store, and these Terms are subject to them.
The app is free and sells nothing. Subscriptions are bought and managed on the web, not through the App Store or Google Play.
We release updates through the stores. We may end support for older versions of the app and for older versions of iOS and Android, and an unsupported version may stop working.
Apple
These Terms are between you and Nexus. Apple is not a party to them and has no obligation to provide any maintenance or support for the app. Nexus, and not Apple, is responsible for the app and its content, for any claim that the app infringes anyone's rights, for any product liability or other legal claim relating to it, and for any warranty, whether or not one is disclaimed elsewhere in these Terms. If the app fails to conform to any warranty, you may notify Apple, and Apple will refund the purchase price of the app, which is nothing; beyond that refund Apple has no other warranty obligation to you in respect of the app.
Apple and its subsidiaries are third-party beneficiaries of these Terms, and may enforce them against you. You confirm that you are not located in a country subject to a US Government embargo or designated as a terrorist-supporting country, and that you are not listed on any US Government list of prohibited or restricted parties.
Websites and domain names
You can add a website to your BusinessOS subscription. We register a domain name for you, write a website from the information already in your workspace, and host it on that domain. Each workspace can have one website. This section and the ones that follow apply only if you add one.
Your domain name
We register your domain through Cloudflare Registrar for a one-year term, and only once your payment has gone through. The owner of your BusinessOS workspace is the registrant of record, using their name and email address, so the domain belongs to you and not to us. We hold it in our Cloudflare account, pay the registry for it, and manage it on your behalf.
The rules of the registry for your domain ending, and Cloudflare's own registration terms, apply to your domain as well as these Terms. They can set requirements we cannot change, such as which contact details must be provided or published and when a domain can be moved to another provider.
Automatic renewal is switched on when we register your domain. Each yearly renewal is charged separately, about a month before the domain renews, at that year's price for its ending. You can switch automatic renewal off on the Domain tab of the Website page. A domain that is not renewed expires at the end of its term and may then become available for anyone to register. If your BusinessOS subscription has been unpaid for 45 days, we switch automatic renewal off, as set out under Ending or pausing your website below.
You can move your domain to another provider. Start a transfer from the Domain tab, or email us. We unlock the domain and give you its transfer code. There is an administration fee of £20, which we invoice when you ask for the transfer. Transfers are handled by our team, so the code may not be available straight away. Your website stops being served from the domain once the transfer completes.
Website fees
Setting up a website is a one-off payment made up of three parts, all shown before you pay:
- £49 to build the website.
- The first year of your domain, charged at the price shown at checkout. The price depends on the domain ending, and it is fixed when you choose the name. There is no domain charge for a domain you already own.
- If you pay monthly, £15 for your first month of hosting.
After that, hosting is £15 a month, or £144 a year if you pay annually, billed on your BusinessOS subscription on the same billing date as anything else you have with us. If you pay monthly, it is charged from your next billing date after your website goes live, so your first month may be slightly shorter than a full month. If you pay annually, the rest of your current plan year is charged when your website goes live.
If you pay annually, each domain we register for you comes with a credit of £15 a year, applied when it is registered and at each renewal. A domain that costs £15 or less is then free for that year, and for one that costs more you pay the difference.
Website fees, including the domain and the transfer fee, are not refundable once paid.
Publishing, content and takedown
You are responsible for what your website says, including anything we or BusinessOS's assistant wrote for it once you have approved it. Nothing is published until you have approved it and we have then reviewed it. Our review is a check on quality and on these Terms. It is not a check that what your site says is accurate or lawful, and we may decline to publish a version that we consider breaches them.
Anyone can report a website we host to [email protected]. We review the reports we receive, and we may suspend a live website straight away if we consider that it breaches the acceptable use rules above. A suspended website stops being served, but it is not deleted, and we can put it back once the reason for the suspension has been dealt with.
The content of your website, meaning its words, pictures and settings, is part of Your Data. The software, layouts and templates we use to build and serve it remain ours. When your website goes offline, its published copy and images stay on our hosting so that it can come back. They are deleted when your workspace is erased.
Ending or pausing your website
You can cancel your website on the Domain tab. The hosting fee stops straight away, and your website stays online until the end of the period you have already paid for, or for at least seven days if that is later. Until then you can change your mind. After the website has gone offline, starting again is a new order.
Cancelling your website does not cancel your domain. It stays registered to you, but we switch automatic renewal off, so it is not renewed and charged for without a website on it. Unless you transfer it or arrange its renewal, it expires at the end of its current term.
If a payment for your BusinessOS subscription fails, we take your website offline. It comes back once the payment goes through, unless we have also suspended it under the acceptable use rules. If the payment has still not gone through 45 days after it failed, we also switch automatic renewal off and email you to say that the domain will lapse when its current term ends unless you pay what is owed or transfer it to another provider. If your subscription ends, we also take your website offline.
If you close your workspace, we take your website offline (normally straight away, and otherwise as soon as our hosting provider allows), switch automatic renewal of your domain off, and email you to explain how to transfer the domain to another provider before it expires. A domain you registered elsewhere and manage yourself is not affected. If the closure is cancelled within the 30-day grace period, we put your website back online and switch automatic renewal back on. Otherwise we delete your website's published copy and images when the workspace is erased, and the domain lapses when its current term ends unless you have transferred it.
Enquiries from your website
A contact form on your website sends what visitors type into it to your BusinessOS workspace, where it is saved as a lead in your contacts and sent to your team as a notification and an email. For that information you are the controller and we process it on your behalf. You are responsible for telling visitors how you will use what they send you, and for having a lawful basis to use it.
Fees and billing
Subscriptions are billed monthly or annually, in advance. You can cancel at any time; service continues until the end of your billing period.
Our prices are exclusive of VAT. Nexus is not currently registered for VAT, so no VAT is charged today. If we register, VAT will be added to our prices at the applicable rate.
Data ownership
You retain all rights to data you submit to the Services ("Your Data"). You grant us a worldwide, non-exclusive, royalty-free license to host, store, copy, transmit, display, back up, and create derived representations of Your Data (such as search indexes and embeddings), and to sublicense these rights to the service providers we use to run the Services, such as cloud hosting, payment processing, and AI model providers.
We may use Your Data to provide, secure, and improve the Services. We do not sell Your Data. This license lasts only as long as we hold Your Data: it ends when you delete Your Data or close your account, subject to the retention periods described in our Privacy Policy.
Termination
We may suspend or terminate accounts that violate these Terms. You can cancel at any time from your account settings.
Disclaimers and limitation of liability
The Services are provided "as is" without warranties of any kind. To the maximum extent permitted by law, our liability is limited to the fees you paid in the 12 months prior to the claim.
