Just the photo you upload to generate a preview, and — only if you message us on Etsy — whatever you choose to share there. No account, no email collection, no payment details ever touch this tool (checkout happens entirely on Etsy).
Your photo is processed by an AI image model (via Replicate, a US-based provider) to generate line art, and by a background-removal step, to produce your keychain preview. It is not used for anything else and is not shared beyond what's needed to generate your design.
Each generated design gets a permanent, unguessable link
(/d/<id>) so you can find it again and use it to order.
It isn't listed publicly or indexed anywhere.
Message us on Etsy with your Design ID and we'll delete your photo and design on request, order or no order.
