It is very important to me to safeguard any data which I may hold; usually temporarily, from my customers, and I will do my utmost to comply with the new EU GDPR rules.
I will never pass any details to other parties. I only have email addresses as a consequence of direct interaction from customers (I would never send unsolicited mail). I also may have customer addresses; but only where the information has been passed to me in order to effectively send parcels out to those customers.
In the next couple of days I will list the full terms and conditions ..
