PRIVACY

WHAT WE STORE, AND WHY

An account is just your e-mail address (magic-link sign-in, no passwords). It exists so your excavation progress, collection and shard balance survive across devices.

When you reach a core and register, your excavator number, chosen alias, rank title, depth and dig time go on that drop’s public register. Signing the ledger stores your message publicly too — other diggers pass it as an echo in the walls.

While you dig, we record how the run went: how deep it got, how long it took, which stretches you spent time in, which passage you climbed back up to hear again, and which stem you held solo. The artist behind that drop sees this only as totals across everyone who dug it — never as your run, and never with your name.

A ♥ you leave in the rock is stored with its depth and the run it came from. Other diggers see the mark; nobody sees who left it.

Artists who submit a drop: we store your request, the files you upload and your contact e-mail, so we can build your world and reach you.

PAYMENTS

Payments run entirely through Stripe. Your card number never touches our servers — we only learn that a payment succeeded, and for which request or shard pack.

ON YOUR DEVICE

Your dig progress, collection and settings live in your browser’s local storage — that is what makes playing without an account possible. Clearing your browser data clears them; an account is the only backup.

We use no advertising cookies and no cross-site trackers. Page-view counts are collected anonymously (Vercel Analytics) so we know which drops get dug.

ON-CHAIN CLAIMS

Claiming a first-50 edition writes your wallet address to a public blockchain. That part is by design permanent and public — that’s what makes it yours.

YOUR RIGHTS

Want your account, register entries, ledger messages or uploaded files gone? One e-mail and we dig them out: timmostrey@gmail.com. On-chain claims are the single exception — no one can unwrite a blockchain.

We never sell or share your data with anyone. There is no one to share it with; this is an archive, not an ad network.
