Section 6

Lawful bases for using personal data

Under UK data protection law, we need a lawful basis for using personal data. Depending on the activity, we may rely on one or more of the following:

Contract: to create and manage your account, operate auctions, record bids, process purchases, arrange collection or delivery, and provide services requested by you.

Legal obligation: to keep tax, accounting, company, payment and transaction records, and to comply with applicable laws.

Legitimate interests: to operate and protect the website, prevent fraud, reduce fake bidding, support customers, maintain records, deal with disputes, and improve our services.

Consent: where required, for example for non-essential cookies or optional marketing communications.

Section 7

Buyer accounts and email verification

We use buyer account data to allow you to register, log in, verify your email address, complete your buyer profile and prepare to bid.

Email verification helps confirm that you control the email address used to register. This helps reduce fake accounts, failed purchases and misuse of the auction process.

We may use authentication cookies, session data, security logs and account records to keep accounts secure.

Section 8

Auction activity and bidding records

When you place a bid, we may record your user account ID, bid amount, bid time, auction item, payment readiness, IP address, and related technical or security information.

We use this information to operate auctions, identify the winning bidder, prevent abuse, investigate disputes and keep appropriate transaction records.

Bids are part of the auction record and may be kept after an auction ends.

Section 9

Payments

Payments may be processed by a third-party payment provider such as Stripe.

We may store payment-related references, such as Stripe customer IDs, payment method status, payment intent references, payment success or failure status, refund references and invoice or receipt records.

We do not store full card numbers on our own website servers. Card details are handled by the payment provider.

The payment provider may process your personal data under its own privacy terms.

Section 10

Collection and delivery

If you win an auction or purchase koi, we may use your name, address, telephone number, email address, order details, delivery instructions and collection information to arrange handover.

Where delivery is arranged by us, we may share only the necessary personal data with suitable delivery, courier or transport providers.

We may also contact you about quarantine, timing, koi welfare, weather, temperature, delivery suitability or collection arrangements.

Section 11

Customer service and communications

We may use your contact details to respond to enquiries, provide account support, discuss auctions, confirm purchases, arrange collection or delivery, deal with complaints, and send important service messages.

Service messages about your account, bids, payments, purchases, collection, delivery or legal notices are not marketing emails.

Section 12

Marketing

We will only send marketing emails where we have a lawful basis to do so.

If we ask for consent to send marketing emails, you can withdraw that consent at any time.

You can unsubscribe from marketing emails by using the unsubscribe instructions provided in the email or by contacting us.

Section 13

Cookies and similar technologies

We use cookies and similar technologies as explained in our Cookie Policy.

Some cookies are needed for the website to work, such as login, security, account session and payment-related cookies.

Non-essential cookies, such as analytics or marketing cookies, should only be used where the required consent has been obtained.

Section 14

Who we share personal data with

We may share personal data with:

  • payment providers such as Stripe;
  • website hosting providers such as Vercel;
  • database and authentication providers such as Appwrite;
  • email service providers;
  • delivery, courier or transport providers;
  • professional advisers such as accountants, solicitors or insurers;
  • regulators, law enforcement or public authorities where required by law;
  • fraud prevention or security providers where needed.

We do not sell personal data.

Section 15

International transfers

Some service providers may process personal data outside the United Kingdom.

Where this happens, we will rely on appropriate safeguards where required by data protection law, such as UK adequacy regulations, approved contractual protections, or provider compliance mechanisms.

Section 16

How long we keep personal data

We keep personal data only for as long as reasonably necessary for the purpose for which it was collected.

Typical retention periods may include:

  • account data: while your account remains active;
  • buyer profile data: while your account remains active or while needed for auction, payment, delivery or legal records;
  • auction and bid records: for as long as needed to operate auctions, handle disputes and keep transaction records;
  • purchase and payment records: for as long as needed for contract, tax, accounting, refund, chargeback, legal or dispute purposes;
  • contact messages: for as long as needed to respond and keep appropriate records;
  • security logs: for a reasonable period to protect the website and investigate misuse;
  • cookie consent records: for a reasonable period to record cookie choices.

We may keep some records for longer where needed for legal claims, fraud prevention, accounting, tax, regulatory or legitimate business reasons.

Section 17

Keeping personal data secure

We use reasonable technical and organisational measures to protect personal data.

These may include account authentication, email verification, server-side database access, access controls, encrypted connections, provider security measures and careful handling of payment information.

No website can guarantee perfect security, but we take appropriate steps to reduce risk.

Section 18

Your rights

Depending on the circumstances, you may have rights under UK data protection law to:

  • access your personal data;
  • correct inaccurate or incomplete data;
  • request deletion of your data;
  • restrict how we use your data;
  • object to certain uses of your data;
  • request data portability;
  • withdraw consent where processing is based on consent;
  • complain to the Information Commissioner’s Office.

These rights are not absolute and may depend on the lawful basis used, legal duties, transaction records, fraud prevention needs and whether we need the information to provide services or keep required records.

Section 19

How to contact us about privacy
