Sumsy is a trading name of Functional Finance Consulting Ltd ("we", "us"), a private limited company registered in England and Wales, company number 16840183. Our registered office is 40 Hereford Road, Feltham, TW13 5BT.

We decide how the personal information described here is used, which makes us its "controller" under UK data protection law.

To ask about anything in this notice, write to us at our registered office.

This notice covers:

If you become a client, we'll explain how we look after your accounting records when you sign up with us.

If you fill in our form or get in touch

What we collect

Why we use it

To reply to you, give you a price and, if you decide to go ahead, start working with you. Our legal reason (the "lawful basis") is that you've asked us to take these steps before entering into a contract with us. Where that doesn't apply, we rely on our legitimate interest in answering enquiries about our business.

We also add your email address to our "do not contact" list, so you don't receive our introductory sales emails. We won't send you marketing emails.

If we've contacted your business

We email limited companies near us to tell them about our services. To do this we use business information that's publicly available:

Our lawful basis is our legitimate interest in telling local businesses about a service that may be useful to them. We send no more than one follow-up.

If you reply "no thanks", ask us to stop, or an email bounces, we add the address to our "do not contact" list and won't email it again. You can also ask us to delete the details we hold about you.

Identity checks when you become a client

We're supervised by HMRC under the Money Laundering Regulations 2017. Before we start working for a new client, the law requires us to check who the client is and who owns and runs the business.

What we collect

How we use it

We'll only use the personal information we collect for these checks to prevent money laundering, terrorist financing and proliferation financing, unless another law allows a different use or you agree to it.

Our lawful basis is that the law requires these checks. The Money Laundering Regulations treat this use as a task carried out in the public interest.

Who else may see it

Who can see your information

These companies act on our instructions. We don't sell your information, and we don't share it with anyone else unless the law requires us to.

Google and our website host may process information outside the UK. When they do, they use the safeguards UK data protection law requires.
