Privacy Policy

Full Bakajiki (“the app”) is made by Square One Technologies, Rajkot, India. This policy explains what the app and this website do with your information.

The short version

Signing in is optional and the game is complete without it. Play as a guest and your call sign, your colours and your match totals stay on your device. Sign in with Google and we keep those same few things, so they follow you to another phone. We never store your email address, your Google name or your photo. There are no in-app purchases. The app does measure how it is used, described below.

The app shows ads, supplied by Google AdMob, and Google collects some data through them. Playing with people over the internet passes through a relay we run; playing with people on your own Wi-Fi does not leave your network.

What stays on your device

The app saves your own settings and preferences on your device so they are remembered next time you open it. This data never leaves your device. Uninstalling the app or clearing its data removes it.

Ads

The app shows ads, and sometimes offers an optional video you can choose to watch in exchange for an advantage. Watching is always a choice — nothing in the app is locked behind one.

The ads are served by Google AdMob. To do that, the Google Mobile Ads SDK inside the app collects and sends the following to Google: your device’s advertising ID and similar device identifiers, your IP address, your interactions with the ads themselves (such as an ad being shown, tapped or watched to the end), and technical diagnostics about how the app is running. Google uses this to choose and measure ads, to produce reports, and to detect fraud and abuse. It is sent over an encrypted connection.

We never see any of it, and we hold none of it. Google’s own policy explains what it does with the data: How Google uses information from sites or apps that use our services. You can reset or delete your advertising ID at any time in Android’s Settings › Privacy › Ads, which is also where you can turn off ad personalisation.

Signing in

You can play everything without an account. If you choose to sign in, the only way offered is Google, and Google handles the sign-in itself — we never see your password. Google gives the app an account identifier, and that identifier is the name under which your save is filed.

What we keep for a signed-in player is the save itself: your call sign, the colours and headgear you chose, anything you have unlocked, and your running totals — matches, wins, eliminations, deaths, best streak and hardest difficulty beaten — together with a revision number and the time it last changed. That is the whole record. We do not store your email address, your Google display name, your photo or your contacts, and we do not use the account for anything except recognising that it is you.

It is held in the Firebase Realtime Database (Google) on servers in the United States, and only that account can read or write it.

A guest save stays on the device it was made on. Signing in does not copy it to us, and signing out hands the game back to it. To have a signed-in save deleted, email us at squareonetechnologies2026@gmail.com from the address you signed in with and we will remove it.

How we measure the app

The app uses Microsoft Clarity to tell us how it is being used — how many people open it on a given day, which of the three ways to play they choose, whether a room they opened was ever joined, and whether a match was played to the end. It records a short list of named moments like those. It does not record your gameplay, your call sign is not sent as part of it, and nothing you type goes to it.

If you are signed in, the session is labelled with the account identifier Google gave the app, so that the same player opening the game next week is recognised as the same player rather than counted twice. Your call sign travels with it only as a readable label for that identifier. Your email address is never sent. Playing as a guest sends no identifier of any kind.

Microsoft processes this on our behalf; their privacy statement explains what they do with it: Microsoft Privacy Statement.

Playing online

When you open or join a room over the internet, the game connects to a relay we run at rooms.fullbakajiki.com. The match is run by the device that opened the room, not by us — the relay only copies game traffic between the devices taking part, and does not record what passes through it.

While a room is open the relay holds its four-character code, how many people are in it and, for a room listed publicly, the call sign of whoever opened it, so that it can appear in the list of rooms. That is deleted when the room closes. The other people in a room see the name and colours you chose, because that is how they can tell who is who.

Playing with people nearby

When you play with others on the same Wi-Fi, the devices talk to each other directly. There is no server of ours in between, and nothing about it leaves your network. The other people taking part see the name and colours you chose for yourself, because that is how they can tell who is who.

Permissions

The app does not ask for access to your location, contacts, camera, microphone, photos or files. It uses your network connection to fetch ads, to reach the rooms relay when you play online, to sign you in if you choose to, and to find other devices on your Wi-Fi; and, if you have enabled vibration, your device’s vibration for haptic feedback.

Children

The app is not directed at children under 13, and we do not knowingly collect information from children.

This website

This website (fullbakajiki.com) sets no cookies and runs no analytics, no advertising and no third-party tracking. It is a set of static pages. Our hosting provider, Firebase Hosting (Google), keeps standard server logs — such as your IP address, the request time and your browser type — for the security and operation of the service. We do not combine those logs with any other information or use them to identify you.

Changes

This policy is updated before a version that changes it is released, and the date at the top changes with it. The ads and the local play described above arrived in version 1.0.1. Optional Google sign-in, the saved profile that comes with it, rooms played over the internet, and the usage measurement described above all arrived in version 1.0.4.
