What we collect
Your first name and email address when you ask for the free workbook, whether you agreed to further emails, and the date you signed up. If you send us an enquiry, the details you give us in the enquiry form. If you take the scorecard, your first name, email address and your scorecard answers. If you ask for one of our free downloads, your first name and email address. If you ask us to tell you when the book is out, your first name and email address.
Why, and on what basis
To reply to your enquiry and arrange a meeting, because we have a legitimate interest in answering people who contact us. To send you the workbook, results or download you asked for, or to tell you when the book is out. If you tick the box, to send you occasional emails, based on your consent, which you can withdraw at any time using the unsubscribe link in every email or by emailing us.
Booking a meeting
If you book a meeting with Mark, Calendly (calendly.com) collects your name, email address and anything you add to the booking, so we can arrange the meeting and send you the invitation. Calendly is based in the USA, and your details are protected when they are transferred there by the Standard Contractual Clauses and the UK Addendum in Calendly's data processing agreement. The booking diary only loads on our Contact page when you click "See Mark's diary".
If we contact you
We contact businesses that we think may benefit from our services, and businesses on behalf of our clients. To do this we use business contact details, such as your name, job title, company, work email address and work phone number, which we get from business data providers and from public sources such as company websites and LinkedIn.
We do this because we have a legitimate interest in business to business sales and marketing. When we contact you on behalf of one of our clients, we do so in their name and on their instructions, and their privacy notice also applies.
If you don't want to hear from us, reply to any message or email hello@c3sales.co.uk and we will stop. We keep a short record of your name and email address so that you are not contacted again.
Who handles it for us
Web3Forms (web3forms.com) passes the details you enter in our forms to us by email. Calendly handles meeting bookings, as above. Our website is hosted by Optimised IT. We do not sell your details.
How long we keep it
We keep sign ups, enquiries, call back requests and prospect contact details for two years after our last contact with you. If you ask us not to contact you again, we keep only the short record described above.
Your rights
You can ask for a copy of your details, ask us to correct or delete them, or object to how we use them, including for marketing. Email hello@c3sales.co.uk. If you are unhappy with how we handle your data, you can complain to the Information Commissioner's Office at ico.org.uk.
