The short version

Clear facts.
Your kind of koi.

KoiLens helps you compare koi from selected Benelux and German dealers. Find your favourites here. Buy directly from the dealer.

Explore koi

From listing to shortlist.

A little homework. More time for the koi.

Start with the facts

Photos, prices and details come from dealer listings. We keep the source visible and missing details unknown.

Independent research. We are not part of the dealers.

Add a second look

Scout
Quality and potential, before price.
Body
Shape visible in the photo.
Separate assessments. A missing score is not zero.

Meet your favourite

Check current availability, health, price and transport with the dealer. They handle the sale and payment.

Your taste gets the final say.
What goes into a score?

Our information system uses detailed calculations, developed over many months, to turn available listing information into useful comparisons. Scout looks at overall quality and potential before price; Body looks separately at body shape and does not change Scout.

Scores are research aids, not verdicts or a judge’s opinion. Photos, pose and missing details affect what can be assessed. Scores cannot promise health, growth, future colour or show results.

Privacy & saved data

Shortlist is a signed-in feature. Your saved koi and optional notes are private to your account. Use your account controls to manage them or request an export or deletion of account data.

Compare stores up to four public koi identifiers in this browser profile. Clearing browser site data can remove local comparisons and preferences; it does not delete your account’s saved Shortlist. Saved entries use their koi ID to find current details, so an unavailable listing is not presented as current.

Cookies and tracking

KoiLens does not include product analytics, advertising pixels or behavioural telemetry, and it does not send usage events to a measurement service. The hosted site uses necessary cookies to sign you in and protect account actions. Sign-in normally lasts for the browser session; choosing to stay signed in keeps it for up to 30 days. The local and static versions do not use sign-in cookies. UX measurement is currently on hold.

Loading source media or following an external dealer link can connect your browser to that third party, which applies its own privacy practices. KoiLens does not control those services.

If you email Van Raaij Solutions, the operator receives your email address and the information you choose to send. That information is used to answer the request, investigate a factual correction or removal, and keep records reasonably needed for the request or required by law. It is not used for marketing. You may ask for access, correction, or deletion of your contact information by using the address below, subject to applicable legal obligations.

Buyer Pass billing and receipts

When you buy a Buyer Pass, Van Raaij Solutions records your receipt name, verified email address, billing country, selected pass, amount and VAT, payment references and status, access dates, accepted purchase terms and request to start immediately. We also record any withdrawal or refund. We use this information to perform the purchase agreement, provide paid access, send service emails and handle your requests. We retain accounting information to meet our legal obligations. Buying a pass does not subscribe you to marketing.

Mollie receives your email, billing country, order reference and payment instruction. You enter payment details in Mollie's checkout. Mollie processes payment data under its own privacy notice. KoiLens does not collect your card security code or online-banking password.

We use Supabase to store account and billing records, Render to host the website and its services, Amazon SES to send receipts and other service emails, and Microsoft 365 to handle support correspondence. These providers receive the information needed for those services.

If you use the public withdrawal or termination form, we record the name, contact email, purchase reference, declaration, requested end date and any reason you supply, together with the time received and confirmation delivery status. We use this information to handle your declaration and meet our legal obligations. Submitting a declaration does not subscribe you to marketing.

Completed purchase records are subject to Dutch accounting retention requirements, normally seven years, or ten years for records covered by the VAT One Stop Shop scheme. Deleting your account does not erase financial records we must retain, although it removes your account access. Contact info@koilens.com for billing or privacy questions, or to request access, correction or deletion, subject to applicable legal obligations.

Terms & buying with a dealer

When you follow a dealer link, you leave KoiLens. The dealer’s own terms and privacy practices apply. Photos and listing material belong to their respective owners; attribution stays with the source.

A KoiLens Buyer Pass is a separate purchase of research access. Its price and purchase terms are shown before you pay.

Seller and service

KoiLens is operated by van Raaij Solutions, a Dutch sole proprietorship,
at Sint Adelbertusweg 15C, 1935 EM Egmond-Binnen, Netherlands.
KVK registration: 74770454. VAT identification: NL001165172B98.
Contact info@koilens.com or telephone +31 6 40072444 for help or complaints.
Submit withdrawal notices through the online function, email or the form below.

A Buyer Pass gives you access to the full current KoiLens research catalogue,
New Koi, Price Drops, breeder and variety searches, and the associated listing
details. Both passes include the same features. KoiLens provides research and
comparison information; it does not sell the koi. Any koi purchase, transport
or reservation is a separate agreement with the relevant dealer.

Price, payment and duration

Choose three calendar months for €39 or twelve calendar months for €99.
These are total prices including applicable VAT, paid upfront through Mollie.
There is no automatic renewal or recurring charge.

For a new pass, access starts when your payment has been confirmed. Your
account shows the exact start and end of the paid period in Amsterdam time.
Your receipt also records these timestamps; a timestamp ending in Z is UTC.
Calendar-month anniversaries use the last day of the ending
month when that month has no corresponding date.

You can purchase a manual renewal during the final 30 days of an active pass.
Its paid period starts when your current pass ends. A purchase after expiry
starts a new period when payment is confirmed. Each purchase has its own price,
duration and terms, which you can review before paying.

Your pass ends automatically. No cancellation is needed to prevent another
charge. Your free account, personal notes and saved selections remain, although
access to restricted listing details requires another active pass.

Refund policy

We do not offer voluntary refunds beyond your statutory rights. If you change
your mind outside the applicable statutory withdrawal period, we do not refund
the unused portion of your pass unless the law requires it. Finding or buying
a koi does not itself create an entitlement to a refund of your Buyer Pass.

This policy does not limit your statutory withdrawal rights described below,
including any applicable extension, or your rights if the service does not
conform to the agreement, including any legally required refund or price
reduction. Starting to use the service does not waive these rights.

Starting immediately and withdrawing

At checkout, agreement to these terms and your request to start the service
immediately are separate confirmations. Starting immediately does not remove
your statutory withdrawal rights.

You can withdraw from an online purchase within the applicable 14-day statutory
period without giving a reason. Use Withdraw from purchase at /withdraw
(also available from the website footer without signing in), the withdrawal
action for the order in your account, or email info@koilens.com with a clear statement that you wish to
withdraw, your name, account email and order reference. Contact support if you
cannot access your account. Sending the notice before the statutory deadline
is sufficient.

We acknowledge the request by email. The account action remains available so
you can submit a notice for review, including when a statutory extension applies.
Its availability does not extend your refund entitlement. Acknowledgement
confirms receipt of your request, not that the refund has already been paid.
Where the law permits a
charge after your express request for immediate service, we deduct only the
proportion of the pass price corresponding to the paid
period actually supplied before you notified us. This deduction is based on
elapsed service time, not how many koi you viewed or whether you bought a koi.
An unused renewal period has no supplied service to deduct. There is no
additional cancellation or activation fee. If the legal conditions for a
deduction have not been met, we do not deduct a service charge.

We return the amount due within the legally required period, normally within
14 days after receiving your withdrawal notice, using the original payment
method unless another arrangement is expressly agreed without additional
cost to you. Withdrawal refunds, full refunds and payment reversals end the access provided by that order. A statutory price reduction can leave the remaining pass access in place.

Terminating your pass

You can submit a termination at /terminate using Terminate your contract
in the website footer. You do not need to sign in. Enter your name, a reference
identifying your purchase, the email address for confirmation, the type of
termination and any requested end date. For extraordinary termination, state
the reason. If you leave the end date empty, your declaration requests the
earliest legally possible termination date. Press Terminate now to submit.
The form is also available in English and Dutch.

We record your declaration and its receipt time, provide a downloadable
confirmation and send it to the email address you supplied. Ordinary termination
does not shorten an agreed fixed term unless the law provides otherwise; your
pass already ends automatically without renewal. Your statutory rights to
extraordinary termination remain unaffected. A termination declaration does
not itself create an entitlement to a refund. Support reviews the applicable
termination date and any legally required refund under your purchase terms.

Service quality and assistance

Dealer information and availability can change. Confirm purchase-critical
details with the dealer. Scout and Body assessments are research aids and do
not guarantee health, future development, show results or financial returns.

If paid access does not work as described, contact info@koilens.com. Your
statutory rights to a conforming digital service and applicable remedies,
including correction, price reduction or termination, remain unaffected.

Dutch law applies without removing mandatory consumer protections or court
rights that apply in your country of residence. The privacy notice explains
account information, payment processing, receipt information and legally
required financial retention.

Terms of use and disclaimer

By using KoiLens, you agree to use it as an informational research aid and to make your own decisions. If you do not accept these terms, do not use the service.

Dealer facts, third-party media, and KoiLens assessments may be incomplete or contain errors. The service is provided on an “as available” basis without a promise that every feature or source will be uninterrupted or error-free. Nothing on KoiLens is veterinary, financial, investment, or other professional advice.

To the extent permitted by applicable law, Van Raaij Solutions is not responsible for indirect or consequential loss arising solely from reliance on KoiLens content or from a third-party destination. Nothing in these terms excludes liability or statutory consumer rights that cannot lawfully be excluded.

These terms are governed by the laws of the Netherlands. Mandatory protections and jurisdiction rights available to consumers under applicable law continue to apply.
