graphicle.dev keeps an email address only for the newsletter. To have it deleted, give the address: it gets a notice with a link to cancel, and the deletion is done within 90 days, usually much sooner, followed by an email saying when.
What stays: a keyed, one-way hash of the address in the record of gift passes, kept 369 years so each address gets one gift pass; passes already issued keep working.
