Block Puzzle is a Zummon game. This page explains the limited account, room, Rank, and payment data used to operate it.
Account and payments
Google sign-in is optional. When you sign in, Firebase stores your public profile name and photo, your chosen block style, your cosmetic entitlements, and your Plus access period together with the payment reference used to grant it. Signing out stops that data from being read on this device. If you pay with crypto, the payment is taken by NOWPayments, which sees the coin and wallet you pay from; the order reference we send it contains your player ID, and we receive back only a payment ID and its status, and store the payment ID with your Plus period. If you email a payment ID because a payment did not unlock Plus, that message, your email address, your player ID, and anything attached stay in the developer's email inbox and are used only to grant and check your access.
Rooms and play
A Device room, including the game on the home page, runs entirely in your browser's memory and sends nothing to a server. A Public room stores a random player ID kept in this browser, the shared board and scores, your display name, and, if you are signed in, your profile photo and Plus expiry. Public rooms are listed for anyone to find and join, and anyone holding the room link can open it. Room data is removed when the last member leaves.
Rank
Finishing a Public room adds a result under your device player ID. Rank publicly shows a display name, an active Plus badge, and win, lose, and draw totals. It does not publish room IDs, boards, or moves. Results are submitted by the player's own browser, so Rank is casual rather than verified.
Your choices
You can play without signing in, and Device rooms need no network connection at all. Clearing this browser's site data removes the stored player ID, which also detaches you from your existing Rank record.
