What we keep when you write to us, why, and for how long.
What we keep
Only what you type yourself. If you use the enquiry form or the basket we keep your name, your email address, your telephone number if you give one, your message, and the reference codes of the pieces you are asking about.
Alongside each message we also keep a scrambled version of your IP address and the name of your browser. The scrambling only works one way: we cannot turn it back into an address. It is there to stop the form filling up with automated messages.
If you give your email address to the newsletter box it lands in the same place. There is no newsletter and no mailing list yet; we hold the address until there is.
Why
So we can answer you. An enquiry is a message, never an order: you buy nothing on this site and you are never asked to pay.
We do not sell your details, we do not share them for advertising, and we do not use them to follow you around.
How long
Two years after we last spoke, then we delete it. Ask us to remove it sooner and we will.
Who else sees it
This site runs on Vercel and the data sits in a database at Supabase, inside the European Union. Email goes through Resend and through our own mailbox. Those companies handle it on our behalf and do not use it for themselves.
If you allow statistics, Google Analytics processes your visit. If you allow the map, or click it, Google processes that. Allow neither and nothing reaches Google at all.
Your rights
You can ask what we hold about you, have it corrected, or have it deleted. Write to info@yellow-hat.nl and we will sort it out.
If you are unhappy with how we handle it, you can complain to the Dutch data protection authority, the Autoriteit Persoonsgegevens.
