To fulfil your order, you must provide me with certain information (which you authorised Etsy to provide to me), such as your name, email address, postal address, payment information, and the details of the product that you’re ordering. You may also choose to provide me with additional personal information (for a custom orders for example), if you contact me directly.

Information about my customers is important to my business. I share your personal information for very limited reasons and in limited circumstances, as follows:

Etsy. I share information with Etsy as necessary to provide you my services and comply with my obligations under both the Etsy Seller Policy and Etsy Terms of Use.

Service providers. I engage certain trusted third parties to perform functions and provide services to my shop, such as delivery companies. I will share your personal information with these third parties, but only to the extent necessary to perform these services.

If you reside in certain territories, including the EU, you have a number of rights in relation to your personal information. While some of these rights apply generally, certain rights apply only in certain limited cases. I describe these rights below:

Access. You may have the right to access and receive a copy of the personal information I hold about you by contacting me via Etsy Convo.
Change, restrict, delete. You may also have rights to change, restrict my use of, or delete your personal information. Absent exceptional circumstances (like where I am required to store data for legal reasons) I will generally delete your personal information upon request.

TL;DR version: I use your address to send your order, the postal system will also use this address for obvious reasons. Etsy stores this information and you may request for me to delete your information.
