If you have signed up for the less-stuff mailing list I have your email address and all my mailouts are through Mailchimp. You can unsubscribe at any time and I do not add people to it. You have to opt in yourself.
If you have bought something from my shop I will have your details. These are needed to post physical items and to send you digital downloads. I also send you an email after you have bought something to check it is ok and to ask you for a quick review.
If you want me to remove your details from the shop at any time please let me know. I’ll need your name and the email address you used so I can find you.
I will never sell your details on, or use them for anything other than the legitimate reason they were given to me.
You can email me on email@example.com if any of this worries you.
