Privacy Policy

Last updated: 31 August 2026

Kalabux is developed by Jolly Good Apps. This policy explains what information Kalabux handles when you play, how it is used, and your rights in relation to it.

The short version: Kalabux is a single-player game with no accounts. Your progress is saved on your own device. To help us improve the game, the app sends us anonymous records of how the game is played, and uses Google Analytics for Firebase to measure how far players get. Kalabux shows ads, which is what keeps it free; in the UK and EEA you are asked first. We never sell your data.

1. What We Collect

Kalabux has no login, no player profile, and no online scoreboard. We do not ask you for any personal information — no name, email address, phone number, contacts, photos or precise location. Specifically:

• Game progress — your factory layout, coins, upgrades, research and settings are saved locally on your device, so you can pick up where you left off. There is no cloud save and no copy of your game on our servers.
• Anonymous gameplay records — to understand how people play Kalabux — which parts are fun, confusing, or too hard — the app records the moves you make during a play session (placing pipes, mixing paint, buying supplies, starting a new day, and so on), the resulting in-game state (such as coins, day number and factory layout), and the timing of those moves. This is gameplay only: no account, no contact details, no location, no device identifier and no advertising identifier. Each session is tagged with a random, one-time code purely so we can tell one session apart from another; it is not linked to you, to your device, or to your other sessions. These records are sent to a server operated by Jolly Good Apps at kalabux.com. As with any request over the internet, our web server receives the network (IP) address the upload came from and may note it in its standard server logs; we do not use those logs to identify players or to build a picture of anyone's play.
• Analytics — Kalabux uses Google Analytics for Firebase to measure how far players get, so we can see where people stop playing and fix it. It reports a small, fixed set of events: finishing the tutorial, completing a day (with the day number), reaching days 3, 7 and 30, asking the foreman for help, earning a commendation, and taking the extended-hours licence. It also records which language pack the game is displaying. To do this, Google collects a randomly generated app-instance identifier for your installation, together with technical information including your device model, operating system version, app version, device language and an approximate region derived from your IP address. Because the app declares Android's advertising-ID permission, Google Analytics for Firebase may also collect your device's advertising identifier on Android. None of this asks for or includes your name or contact details.
• Advertising — since version 1.0.2 Kalabux shows ads, supplied by Google AdMob. There are three: a short film you may choose to watch when a paint tank runs dry, in exchange for topping up every tank; a full-screen ad between the working day and the maintenance evening; and a small printed leaflet among the morning post. To serve them, Google receives your device's advertising identifier along with technical information about your device, and may use it to choose which ads you see and to measure whether you interacted with them. In the UK, the EEA and Switzerland you are asked for your choice before any personalised ad is shown, using a consent message certified by Google; if you decline, you will still see ads, but they will not be personalised. On iOS, Apple's App Tracking Transparency prompt appears first, and if you say no, the advertising identifier is not available to us or to Google at all. You can withdraw or change your choice at any time in your device settings — see section 5.

2. How We Use It

• To understand how Kalabux is played — which parts players enjoy, get stuck on, or find too difficult — so we can fix problems and make the game better.
• To see how many players get past the first day and keep playing, which tells us whether a change to the game helped or hurt.
• To check that the game reads correctly in each language we ship.
• To show ads and to measure whether they were seen or acted on, which is what pays for the game.

We do not build advertising or user profiles ourselves, and we never sell your data. Google, as our advertising provider, does use the data described above to select and measure ads; that processing is governed by Google's own policies, linked in section 3.

3. Where Your Data Lives & Third Parties

• On your device — all of your game progress is stored on your device by the app.
• Our server — the anonymous gameplay records are sent to and stored on a server operated by Jolly Good Apps, used only to analyse and improve the game. They are never sold, and never shared for advertising.
• Google (Firebase / Google Analytics) — the analytics events described above are processed by Google on our behalf, and are governed by Google's own policies: see Google's Privacy Policy and how Google uses information from apps that use its services. Google may process this data outside the UK and EEA under its standard data-transfer terms.
• Google AdMob — the ads described above are selected and delivered by Google AdMob, which receives your advertising identifier and technical device information in order to do so. This is a separate purpose from the analytics above, and is covered by the same Google Privacy Policy. Your consent choice in the UK, EEA and Switzerland, and your App Tracking Transparency answer on iOS, both govern what AdMob may use.
• App stores — Kalabux is distributed through Google Play and the Apple App Store. When you download or update the app, those stores handle the transaction under their own privacy policies. We do not receive personal information from them.

4. Children

Kalabux requires no account and has no chat or social features. It is rated for ages 13 and over, is intended for a general audience, and is not directed specifically at children under 13; we do not knowingly collect personal information from children. Because the analytics described above can involve an advertising identifier on Android, the app is intended for players aged 13 or older. If you believe a child has provided us with personal information, please contact us and we will address it.

5. Deleting Your Data

Your game progress is stored on your device, so you are in full control of it:

• Uninstalling Kalabux permanently removes all game data from your device.
• Alternatively, you can clear the app's data from your device settings (Android: Settings → Apps → Kalabux → Storage → Clear data). This also resets the app-instance identifier used by analytics, so the new installation cannot be connected to the old one.
• You can reset or delete your advertising identifier, and opt out of personalised advertising, in your device settings (Android: Settings → Privacy → Ads; iOS: Settings → Privacy & Security → Tracking, and Apple Advertising).

The anonymous gameplay records we receive carry no identifier that links them to you or your device, so — while they contain nothing that identifies you in the first place — we have no way to single out and delete an individual player's records. We hold no personal data about you on our servers. To ask a question about any of this, or to make a request under data-protection law, contact us at the address in section 7.

6. Changes to This Policy

If we make significant changes to this policy, we will update the date at the top of this page. Continued use of Kalabux after changes are posted constitutes acceptance of the updated policy.
