Quarvex is a cloud accounting service operated by Britannia Digital Limited, a company registered in England and Wales (company no. 17253824), registered office 66 Paul Street, London, England, EC2A 4NA ("Quarvex", "we", "us", "our"). "Service" means the Quarvex web application and website. "You" means the person or business using the service. "Content" means the data and files you enter or upload.
Where a free trial is offered, you can use the service for the stated period. A payment method may be required to start it; unless you cancel before the trial ends, your plan begins and the first payment is taken. We may change or withdraw trial terms at any time.
You can cancel at any time from your account. Access continues until the end of the period you have already paid for, after which the subscription ends. Except where the law requires otherwise, payments already made are non-refundable, including for partly used periods.
You own the Content you enter. You grant us the limited right to host and process it solely to provide and improve the service. You are responsible for the accuracy of your Content — including any figures submitted to HMRC — and for keeping your own copies of important records.
We process personal data in line with our Privacy Policy and UK data protection law (UK GDPR and the Data Protection Act 2018). We use appropriate technical and organisational measures to protect your data, but no online service can be guaranteed completely secure.
Quarvex helps you prepare and submit VAT returns to HMRC under Making Tax Digital. You remain solely responsible for reviewing and confirming every figure before submission, and for meeting your own tax obligations and deadlines. Submissions are sent to HMRC's systems; we are not responsible for HMRC outages, rejections or processing.
Quarvex is a software tool. It does not provide accountancy, tax, legal or financial advice, and nothing in the service should be relied on as such. If you need advice, please consult a suitably qualified professional.
If you use Quarvex to act for clients, you confirm you are authorised to do so and, where you file as a tax agent, that you hold the necessary HMRC agent authorisation and any required supervision (such as anti-money-laundering supervision). You are responsible for your clients' data and for your own arrangements with them.
The service relies on third parties such as HMRC, our payment provider and email delivery. Their availability is outside our control, and your use of them may be subject to their own terms.
You agree not to misuse the service, interfere with its operation, attempt unauthorised access, reverse engineer it, resell it without our permission, or use it for unlawful purposes. We may suspend or restrict accounts that breach these terms.
The service — including its software, design and branding — belongs to Britannia Digital Limited and its licensors. We grant you a non-exclusive, non-transferable right to use it for the duration of your subscription. Your Content remains yours.
We aim to keep the service available but do not guarantee uninterrupted access. We may carry out maintenance and updates, and may add, change or remove features. We take reasonable steps to back up data, but we recommend you export and keep your own records.
You may stop using the service at any time. We may suspend or end your access if you breach these terms, fail to pay, or where required by law. On termination your right to use the service ends, and we may delete your Content after a reasonable period.
To the fullest extent permitted by law, we are not liable for indirect or consequential loss, or for loss of profit, revenue, data or goodwill. Our total liability arising from the service in any 12-month period is limited to the fees you paid for that period. Nothing in these terms limits liability that cannot be limited by law, such as for death or personal injury caused by our negligence, or for fraud.
You agree to cover us for losses and claims arising from your misuse of the service, your breach of these terms, or your breach of the rights of others.
We may update the service and these terms from time to time. We will publish the current version here and, for significant changes, give reasonable notice. Continuing to use the service means you accept the updated terms.
We are not liable for failure or delay caused by events beyond our reasonable control, including outages of HMRC, hosting, payment or internet services.
These terms are governed by the laws of England and Wales, and the courts of England and Wales have exclusive jurisdiction.

This policy applies to the Quarvex web application and website, and to personal data we process about account holders, the people they invite, and visitors. We process personal data in line with the UK GDPR and the Data Protection Act 2018.
When you add your own customers, suppliers or staff, you are the controller of that data and we process it on your behalf as a processor, to provide the service. You are responsible for having a lawful basis to enter it and for telling those people how their data is used.
We share personal data only with service providers who help us run Quarvex, under contract and only as needed:
We do not sell your personal data, and we do not use it for advertising.
Where a provider processes data outside the UK, we rely on an adequacy decision or appropriate safeguards (such as the UK International Data Transfer Agreement / Addendum) to protect it.
We keep your data for as long as your account is active and as needed to provide the service. After you close your account we delete or anonymise personal data within a reasonable period, except where we must retain certain records to meet legal, tax or accounting obligations.
We use appropriate technical and organisational measures — including encryption in transit, hashed passwords and access controls — to protect your data. No online service can be guaranteed completely secure, and you are responsible for keeping your password confidential.
Under UK data protection law you have the right to access, correct, delete or restrict your personal data, to object to certain processing, to data portability, and to withdraw consent where we rely on it. To exercise any of these, email support@quarvex.com. You also have the right to complain to the Information Commissioner's Office (ICO) at ico.org.uk.
We use only the cookies necessary to sign you in and keep the service working (such as your session cookie). We do not use advertising or third-party tracking cookies.
Quarvex is a business tool not intended for anyone under 18, and we do not knowingly collect data about children.
We may update this policy from time to time. We will publish the current version here and, for significant changes, give reasonable notice.
