Who we are

Sunday Octopus is a trading name of Darren Cooper. We are the data controller for personal data collected on this website. You can contact us at hello@sundayoctopus.com.

What we collect and why

  • Enquiry and booking forms: your name, email, phone (optional), business name, town, website and message. We use these to reply to you, arrange a discovery chat and reply to you. Lawful basis: steps taken at your request before entering a contract, and our legitimate interest in replying to enquiries.
  • Package builder: the modules you choose, sent only if you press "Send me this package".
  • AI visibility check: your website address and email, so we can run the check and send you the results.
  • Mailing list: only if you ask to join. Lawful basis: consent. You can unsubscribe from any email.

The chat assistant

Our assistant, Otto, answers questions using this website's content. Messages you send may be stored so Darren can read them and follow up. If you give your details in the chat, we use them in the same way as the enquiry forms. Please don't share payment card details or passwords in the chat or forms. If our AI service is switched on, messages are processed by our AI provider under a data processing agreement and are not used to train their models.

Who we share it with

Only the service providers we use to run this website and reply to you, each under a contract that protects your data: website hosting and email delivery (Cloudflare) and email (Google Workspace). If we add a mailing tool, booking calendar or AI chat provider, we will list it here. Some may process data outside the UK; where they do, appropriate safeguards such as the UK International Data Transfer Addendum are in place. We never sell your data.

How long we keep it

Enquiries that don't become work: up to 12 months, then deleted. Client records: for the length of our contract plus six years, for legal and tax reasons. Mailing list: until you unsubscribe.

Analytics

We use Cloudflare Web Analytics, which doesn't use cookies or track you across sites, and we count button clicks on this site anonymously. See our cookie notice.

Your rights

You can ask to see, correct, delete or move your data, object to how we use it, or withdraw consent at any time. Email hello@sundayoctopus.com. If you're unhappy with how we've handled your data, you can complain to the Information Commissioner's Office at ico.org.uk.

Our clients' customers

When we build systems for clients, the client is the data controller for their customers' data and we act as their processor. Every client gets a data processing agreement and a UK GDPR-compliant set-up.
