This is a draft. It describes accurately what the software actually stores and sends, which is the hard part and the part worth getting right first. It is not legal advice. Have a lawyer read it before launch — in particular whether you need a GDPR representative, a UK/EU cookie banner, a CCPA "do not sell" notice, or a data processing agreement with Google, depending on where your players are.
The short version: ThrownZone collects very little, because it needs very little. There is no advertising, no tracking across other sites, no analytics product, and nothing is sold or shared with anybody.
When you create an account
| What | Why | Kept |
|---|---|---|
| Email address | To sign you in, verify the address, and reset a password | While the account exists |
| Display name | Shown on leaderboards and the marketplace | While the account exists |
| Password | Sign-in. Handled entirely by Google Firebase Authentication — we never see it | Firebase's, not ours |
| Date of birth | Checked once, to confirm you meet the age requirement | Not kept. We store only that the check passed, and when |
If you sign in with Google instead, Google tells us your email address, your name and your profile photo. We do not receive your Google password.
While you play
| What | Why |
|---|---|
| Your cards, credits, packs, contest entries and results | It is the game |
| Every transaction, with a reason | The balance is the sum of the ledger, not a stored number. It is how a dispute gets an answer |
| Sign-in times, and the length of each session | Showing you your own play history, and spotting an account being used by somebody who should not have it |
| Your IP address and browser user-agent, on sign-in | Rate limiting, and noticing an account being broken into |
What we do not collect
No location, no contacts, no device identifiers, no advertising identifiers, no behavioural profile, no data from other sites, and no payment information of any kind — there is nothing to pay for.
ThrownZone sets no advertising or analytics cookies, and there are no third-party trackers on the page.
Firebase Authentication stores a sign-in token in your browser so you stay signed in. The game stores a few of your own preferences — your watchlist, your alerts, your place on the leaderboard — in your browser's local storage. When you sign out, that is deleted.
That is the entire list. Nobody buys data from us, because we do not sell it, and nobody is given it for their own purposes.
Your display name, your position on public leaderboards, your contest results, and any card you list on the marketplace. Nothing else — not your email address, not your account identifier, not your balance, not your collection.
Wherever you live, you can ask us to:
Much of this is already in the app: your wallet, your full statement and your complete activity history are all on your own account page, and they are the same records we hold.
Email support@meatballparmff.com and we will answer within 30 days.
On deletion. When we delete an account we remove the email address, the display name and everything that identifies you. We keep the underlying ledger entries, with the account identifier replaced by an anonymous one, because a shared economy's transaction history cannot be unpicked without corrupting other players' balances — if you sold somebody a card, their card has to keep its history. Those records cannot be linked back to you afterwards.
No system is perfect. If something happens that affects you, we will tell you, and we will tell you what we know rather than waiting until we know everything.
ThrownZone is for adults, and the age check is at sign-up. We do not knowingly collect anything from a child. If you believe a child has created an account, email support@meatballparmff.com and we will delete it.
On servers in the United States. If you are in the UK or the EEA, your data is transferred there under the standard contractual clauses that Google and Amazon publish for their services.
We will post a new version here and update the date. If a change matters, we will tell you in the app rather than assume you check this page.
