Privacy policy

Last updated: 6 November 2026

Flockaboom: Castle Smash (Android package com.gegirhasut.flockaboom, developer MPKB Production) is a single-player game. This policy explains what data the game handles. Contact: gegirhasut@gmail.com.

The game works offline

The whole game can be played without an internet connection. Your progress, stars, gems, settings and finished tutorials are stored only on your device. We do not ask for your name, e-mail, phone number, contacts, location or any account. Without a connection nothing is sent; you only cannot watch rewarded videos.

Anonymous game statistics (our server)

When the device is online and you have agreed, the game sends anonymous gameplay statistics to our own server at undergroundfightgame.com. Until then the events wait in a small, size-limited queue on the device. What is sent:

• a random player number that the game creates on its first start. It is not your advertising ID, Android ID, IMEI or Google account, and it is not linked to them; a reinstall creates a new one;
• the game version, the game language, the operating system and its version, the phone model and its memory size (for crash and performance diagnosis);
• your country as a two-letter code (for example DE): our server derives it from the connection's IP address when the statistics arrive, using a local country database. Only the country code is kept — no city, no precise location, no IP address;
• what happens in the game: session start and end and time played; level start, win, loss or exit (level number, world, attempt, shots allowed and used, stars, score, castle strength left, duration); worlds completed, tutorial steps, in-flight abilities used, the best gate multiplier, a language change;
• rewarded-video events in the game (offered, shown, completed) — no advertising identifiers or ad-network data;
• your consent choice (analytics / ads yes or no), and how many old events the phone had to drop when the queue was full.

We do not store IP addresses with the statistics. The IP address is used only in memory to limit the request rate and to look up the country code, and is not written to the database. Like any website, the web server may keep standard access logs that contain IP addresses; they are not linked to the statistics. The statistics are used only to balance and improve the game; they are not sold and not shared with anyone.

Rewarded videos (Google AdMob)

The only advertising in the game is an optional rewarded video that you may choose to watch for two extra shots when your shots run out. There are no banners and no forced ads. The videos are served by Google AdMob. To show and measure ads, Google may collect device identifiers (such as the advertising ID), the IP address, device and app information and ad interactions. Where required (for example in the EEA, the UK and Switzerland) the game asks for your consent through Google's consent form before personalised ads. Google's privacy policy: https://policies.google.com/privacy; how Google uses data from apps that use its services: https://policies.google.com/technologies/partner-sites; AdMob and privacy: https://support.google.com/admob/answer/6128543.

Analytics (Google Analytics for Firebase)

The game uses Google Analytics for Firebase to understand how the game is played and to measure our advertising (whether people who saw our ad install and play). Firebase may receive in-game events (game start, level start and end, play-time milestones, worlds completed, a rewarded video watched), app and device information collected by the SDK (app version, device model, OS version, language, approximate region derived by Google from the IP address), a random app-instance ID, and — when ad measurement is allowed — the advertising ID. Firebase collection starts only after the consent status is known and follows your choice. Firebase and privacy: https://firebase.google.com/support/privacy.

Your choice

You can play without agreeing to statistics or personalised ads. Where Google's consent form applies, you can change your choice later in the game's settings. You can also reset the advertising ID or opt out of ad personalisation in your Android settings.

Retention and deletion

Our anonymous statistics are kept until you or we delete them; there is no automatic expiry yet. To delete them, open the game's settings and choose Delete player data: the game erases its local save and asks our server to erase every record of your random player number (if you are offline, the request is sent the next time a connection is available). Instructions: undergroundfightgame.com/flockaboom/delete-data/. You may also write to gegirhasut@gmail.com. Data held by Google (AdMob, Firebase) are kept according to Google's own retention settings and policies linked above.

Security

Statistics are sent only over encrypted HTTPS. The statistics page is available only to the developer with a password.

Children

The game is intended for players aged 13 and over. It is not directed at children under 13, and we do not knowingly collect personal data from them.

Changes

If this policy changes, the new version is published on this page with a new date.
