Crimson Colosseum is made by HBK Software Ltd, a company registered in England and Wales (company number 13320244). This policy covers the game on iPhone, iPad, Android, Windows, macOS and Linux (Steam).
In short
The single-player game works offline. Only when you open Online Arena does the game create an online account and use our server. On iPhone, iPad and Android the free game shows ads from Google AdMob (below); there are no ads on Steam. We run no analytics or tracking of our own, and we never sell your data.
What Online Arena uses
The first time you open Online Arena, the game creates an account on our game server (run by HBK Software Ltd on a server at Hetzner in Germany; the same server runs our game Epoch Siege, with separate accounts). It stores:
- An account id and a random install id made by the game, used to sign you in on this device. It is not your device's advertising or hardware id.
- Your public player name (a random name such as Gladiator1234 until you change it). Other players see it in duels and on the leaderboards.
- Your email address and a password, only if you choose to add them, so you can move your account to another device. The password is stored hashed.
- A cloud copy of your saved game (gladiators, progress, achievements, settings), so it can come back on another device.
- Your gladiator's build (name, origin, level, attributes, gear, skills, looks) as a "ghost" that other players fight in ghost duels, and the results of those duels.
- Scores and ratings: duel and live 1v1 ratings, wins and losses, Daily Challenge scores, career wins and your biggest hit, shown on the leaderboards with your player name.
In a live 1v1, the server passes your gladiator's build, your player name and your fight actions to your opponent's device while you play; it does not keep the messages, only the result. There is no chat.
The server also keeps the technical records any internet service needs to run (such as the address your connection comes from, in short-lived logs). We use all of this only to run the online features.
Ads (phones only)
On iPhone, iPad and Android the free game shows ads from Google AdMob (Google Ireland Ltd / Google LLC): a banner in the menus, now and then a full-screen ad when you leave a fight's result, and ads you choose to watch for a reward (a second chance when knocked out, double gold after a win). There are no ads on Steam (PC, Mac, Linux) and none in online fights. To show and measure ads, Google collects data such as your device's advertising identifier, IP address, approximate location from it, device and app information and how you interact with the ads. In the UK, EU and Switzerland the game first asks for your consent with Google's consent form; you can change your choice at any time in Settings › Ad privacy choices. Without consent you get non-personalised ads. On iPhone the game does not ask to track you across other apps. Ads are limited to those rated for teens. How Google uses data: policies.google.com/technologies/partner-sites.
Purchases
Remove ads is a one-time purchase made through the App Store or Google Play. Apple or Google process the payment; we only learn that this install owns the purchase (no card or account details), and the game keeps that on your device. Settings › Restore purchases brings it back on a new device.
Deleting your online data
Online Arena → Account → Delete account removes your account and everything stored with it (name, email, cloud save, ghost, scores) from our server at once. Your careers on your device stay. You can also ask us by email to delete it.
Your saved game
Your gladiators, progress, achievements and settings are saved in a file on your own device. We only receive a copy if you use Online Arena (the cloud copy above). Depending on your device and settings, your platform may keep a copy for you:
- Steam: Steam Cloud keeps your save in sync between your computers (Valve's privacy policy). Steam achievements are handled by Steam.
- Android: Android's backup can include the save in your Google account backup (Google's privacy policy).
- iPhone and iPad: iCloud or computer backups of your device can include the save (Apple's privacy policy).
Deleting the game removes the save from your device.
Links
The "powered by HBK SOFTWARE LTD" badge and the privacy link open our website in your browser. The badge link carries campaign tags that only tell our website the visit came from the game; your browser's normal website rules apply from there.
Children
The game is not directed at children under 13. Online Arena asks for no real name; a player name should not be your real name. If you believe a child has given us an email address, write to us and we will delete the account.
Your rights
Under UK and EU data protection law you can ask for a copy of your online data, have it corrected or deleted, or object to its use. Write to us at the address below. You can also complain to the UK Information Commissioner's Office (ico.org.uk). The legal basis for the online data is providing the online features you ask for.
Changes
If the game's use of data changes, this page will say so before that version is released.
