Privacy Policy

We care about the privacy of your business and your financial data. This page explains what we collect, why we collect it and how you stay in control.

01Introduction

Numbers Calculus (“we”, “us” or “our”) provides accounting software that helps businesses manage invoices, bank feeds, reports and tax deadlines. This Privacy Policy explains what personal information we collect, how we use it, who we share it with, and the choices you have.

By using our website, applications or services (together, the “Services”), you agree to the practices described here. If you do not agree, please do not use the Services.

02Information we collect

We collect information in three ways.

  • Information you give us: your name, username, email address, company details, billing information and any messages you send to our team.
  • Business data you add: invoices, customer and supplier records, bank transactions, tax details and other accounting content you enter or import into the Services.
  • Information collected automatically: device and browser type, IP address, pages visited, actions taken in the product and approximate location derived from your IP address.

If you sign in with a third-party account such as Google or GitHub, we receive basic profile details that you authorise that provider to share.

03How we use your information

We use personal information to:

  • Provide, operate and maintain the Services, including processing your accounting data on your behalf.
  • Create and manage your account, authenticate you and keep it secure.
  • Process payments, send invoices for your subscription and prevent fraud.
  • Send service messages such as security alerts, updates and support replies.
  • Send product news and tips, where you have chosen to receive them.
  • Understand how the Services are used so we can fix problems and improve features.
  • Comply with legal obligations and enforce our terms.

04How we share information

We do not sell your personal information. We share it only in these limited situations:

  • Service providers who help us run the Services, such as hosting, payment processing, email delivery and analytics. They may only use your data to perform services for us.
  • Accountants or team members you invite to your workspace, according to the permissions you set.
  • Authorities or other parties when required by law, or to protect the rights, safety and security of our users and the Services.
  • A successor organisation if we are involved in a merger, acquisition or sale of assets, with notice to you where required.

05Cookies and similar technologies

We use cookies and similar technologies to keep you signed in, remember your preferences, measure performance and understand how people use the Services. Essential cookies are required for the product to work. Optional analytics cookies are used only where permitted.

You can manage cookies through your browser settings. Blocking essential cookies may prevent parts of the Services from working properly.

06Data retention

We keep your information for as long as your account is active and as needed to provide the Services. After you close your account, we delete or anonymise your personal information within a reasonable period, unless we must keep certain records to meet legal, tax or accounting obligations or to resolve disputes.

07Data security

We use administrative, technical and physical safeguards designed to protect your information, including encryption in transit and at rest, access controls and regular backups. No system is completely secure, so we cannot guarantee absolute security, but we work continuously to protect your data and will notify you of a breach where the law requires.

08Your rights and choices

Depending on where you live, you may have the right to:

  • Access the personal information we hold about you and receive a copy of it.
  • Correct information that is inaccurate or incomplete.
  • Delete your personal information, subject to legal retention requirements.
  • Object to or restrict certain processing, and withdraw consent where processing is based on consent.
  • Receive your data in a portable format.
  • Opt out of marketing emails at any time using the unsubscribe link.

To exercise any of these rights, contact us using the details below. We may need to verify your identity before acting on a request.

09International transfers

Our providers and servers may be located in countries other than your own. When we transfer personal information across borders, we take steps to ensure it remains protected, for example through contractual safeguards and by choosing providers that maintain appropriate security standards.

10Children’s privacy

The Services are intended for businesses and are not directed to anyone under 18. We do not knowingly collect personal information from children. If you believe a child has given us personal information, please contact us and we will delete it.

11Changes to this policy

We may update this Privacy Policy from time to time. When we make material changes, we will update the date at the top of this page and, where appropriate, notify you by email or within the product. Continuing to use the Services after a change means you accept the updated policy.
