CoinStackup is a collection tracker for coin collectors. This page says what we keep and what we don't.
What we store
Email, username, name, optional photo, city, state, year you started, what you collect, your coins (dates, grades, photos, cost, market values), messages, and trade requests. We use session cookies to keep you signed in.
What stays private
Cost basis and ROI are only visible to you. Your collection and wish list are public only if you turn those on.
Prices
Market values come from Greysheet / CPG. That is their data, used to value your stack. We don't sell your collection or your email.
If you opt in on the landing page or at register, we may email collector notes. You can unsubscribe. If you never opt in, we only use your email to run your account.
