What we don't do, in plain English.

We don't retarget you anywhere off this site. We don't email you anything you didn't opt into. We don't share it with ad networks, and we don't sell your data.

What we do use, when you allow it: anonymous page analytics to find broken flows, and an opt-in email list for restocks, new lots, discounts, and pricing. Both toggleable any time from /account/privacy.

Boxes below are pre-checked. Untick either if you'd rather not — your call, both ways.

Help improve the site (anonymous analytics + form-masked session replay — THANK YOU!) Restock alerts, new-lot drops, discounts, and pricing updates
