02 · WHAT WE COLLECT
The personal data
we collect.
When you book a call on our website. The booking form asks for:
- Your name, email address and phone number
- The software you use
- The package you are interested in, if you choose one
- An optional note
- The date and time you pick for the call
When you contact us. If you email us, call us or message us on WhatsApp, we keep what you send us and our replies, so we can answer you.
When you become a client. We collect the details we need to agree and run our service. This includes contact details for you and your business, our engagement terms and our fees. It also includes the information we need for anti-money-laundering checks, such as proof of identity and address for the people who own or run the business.
When we keep your books. We work as an invited user inside your own accounting and receipt software. There we see your bank transactions, invoices, receipts and other records. These can include personal data about you and the people your business deals with, such as customers, suppliers and staff. If you ask us to monitor a finance inbox, we only do so with your authorisation and only for the inbox or folders you agree.
Technical data. When you visit the site, your IP address passes through our hosting and Cloudflare so the page can be delivered and protected. Our server does not write request details to a log. When you submit the booking form, your IP address is held in memory for up to an hour to stop repeated automated bookings. It is not saved with your booking.
03 · WHY WE USE IT
Why we use your data
and our lawful basis.
UK data protection law says we need a lawful basis for each use of your personal data. These are the ones we rely on.
- Contract, or steps before a contract. To arrange and hold the call you book, send your confirmation and Google Meet link, prepare a quote and provide the bookkeeping service you sign up for.
- Legitimate interests. To answer your questions, keep a record of what we have discussed, protect our website from misuse and run our business properly. We only rely on this where it does not override your rights. Personal data about your customers, suppliers and staff is used only to do your bookkeeping.
- Legal obligation. To carry out anti-money-laundering checks and keep the records the law requires us to keep, such as business and tax records.
The website does not add you to any mailing list. We do not make decisions about you by automated means that have legal or similarly significant effects.
05 · HOW LONG WE KEEP IT
How long we keep
your data.
- Booking requests. If you book a call but do not become a client, we keep your booking only for as long as we need it to follow up your enquiry, and then delete it.
- Emails and messages. Kept for as long as they are needed to answer you, then for the same period as your booking or client records.
- Client records. Kept for as long as the law requires, including anti-money-laundering and tax rules, and then deleted.
When our work for you ends, you remove our access to your software. The records in your software stay with you.
06 · YOUR RIGHTS
Your rights over
your data.
You have the right to:
- Access. Ask for a copy of the personal data we hold about you.
- Rectification. Ask us to correct data that is wrong or incomplete.
- Erasure. Ask us to delete your data, where we do not need to keep it.
- Restriction. Ask us to limit how we use your data.
- Objection. Object to our use of your data where we rely on legitimate interests.
- Portability. Ask for data you gave us in a format you can reuse.
To use any of these rights, email [email protected]. There is normally no charge. We will reply within one month. We may need to confirm your identity first. Some rights do not apply where the law requires us to keep the data.
If you are a client, you can also remove our access to your accounting software or finance inbox at any time from your own account settings.
Complaints. If you are unhappy with how we use your data, please tell us first so we can put it right. You can also complain to the Information Commissioner’s Office at ico.org.uk.
