what we do with your data, in plain english.
Short version: this website keeps nothing about you. If you email us, we keep what you send until the job is done, and we share it only with the customs representative who files your claim.

this website
preferent.eu sets no cookies and runs no analytics or tracking. It loads nothing from other companies: the fonts, images and the shipment checker are all served from our own hosting. The checker runs entirely in your browser; what you type into it is not sent to us or to anyone else.
Our hosting provider (TransIP, the Netherlands) keeps ordinary server logs, including your IP address, for security and to keep the service running. That is the only trace a visit leaves.
when you email us
If you write to hello@preferent.eu or claims@preferent.eu, we receive your name, your email address, whatever you tell us about your company, and the contents of your message and attachments. Typically that means customs entries, invoices and bills of lading for shipments you want checked.
We use that information for one thing: to answer you, work out whether import duty can be recovered on those shipments and, if you engage us, to recover it. The legal basis is that this is what you asked us to do (performance of a contract, or steps before one), and our legitimate interest in replying to people who contact us.
who else sees it
Refund requests are filed by a licensed customs representative in the Netherlands. When we file on your behalf, that representative receives the shipment documents needed for the filing and nothing more. Customs authorities receive what the law requires for the claim. We do not sell, rent or otherwise pass on your data, and we do not use it for marketing.
Our email runs on TransIP servers in the Netherlands. Your data stays in the European Union.
how long we keep it
Enquiries that do not lead to an engagement are deleted within 12 months. For engagements, we keep the file for as long as the customs authorities can still ask questions about a claim, which is generally seven years under Dutch record-keeping rules, and then delete it.
your rights
You can ask us at any time what we hold about you, ask for it to be corrected or deleted, ask us to stop using it, or ask for a copy. Email hello@preferent.eu and you will hear from us within a month. If you are not happy with how we handle your data, you can complain to the Dutch data protection authority, the Autoriteit Persoonsgegevens (autoriteitpersoonsgegevens.nl).
