Summary

Dualbound has no account and no sign-in, and never asks for your name, email address or contacts. Your game progress is saved only on your phone. The game uses services run by Google to measure how it is played (Google Analytics for Firebase), report crashes (Firebase Crashlytics), adjust game settings remotely (Firebase Remote Config), show ads (Google AdMob) and sell optional ad-free passes (Google Play Billing). Each is described below. The game requests the Internet permission on Android for these services.

What the game stores on your device

To remember your progress, the game saves small files inside its own app storage on your phone:

These files never leave your phone. We cannot see them and cannot restore them. Uninstalling the game or clearing its storage deletes them.

Usage statistics (Google Analytics for Firebase)

The game sends these events to Google Analytics for Firebase:

To count devices, the Firebase SDK creates a random app-instance ID for each installation. Firebase is set up not to collect the Android advertising ID for us (the ad service below uses it). We use these statistics only to improve the game and to balance its difficulty and ad frequency. We do not sell them.

Crash reports (Firebase Crashlytics)

If the game crashes, Firebase Crashlytics sends a crash report: where in the game’s code the crash happened, the app version, device model and operating system version, and a random installation ID that groups reports from the same installation. Reports contain no name, contacts or game progress. We use them only to fix bugs.

Remote settings (Firebase Remote Config)

The game downloads a few settings from Firebase Remote Config, such as how many duels pass before the first ad, the spacing between ads, and difficulty targets. These settings may differ between groups of players so that we can compare them. To fetch them, the SDK uses a random Firebase installation ID.

Ads (Google AdMob)

The game shows a full-screen ad at the end of some stages and offers optional reward ads (for example, to continue after a loss, to double the stars from a stage, or to roll gear once more). The ads come from Google AdMob. There are no banner ads. AdMob is set up only when the game is about to show its first ad, not when you open the game.

Passes (Google Play Billing)

You can buy a prepaid pass for 1 week, 3 months or 1 year. A pass removes ads and does not renew automatically. Payment is handled entirely by Google Play: we never see your card or payment details. The game receives from Google Play only which pass you bought and whether it is active, and keeps that on your phone.

Who receives data

The only third party that receives data from the game is Google, through the services above. Google processes it under the Firebase privacy and security terms and the Google Privacy Policy. We do not sell data, and we do not run our own server for game data.

What the game does not do

Children

The game is not directed at children. It does not ask anyone, including children, for a name, contact details or other personal information.

Changes

If a future version starts collecting or sharing other data, this page will be updated before that version is released, and the effective date above will change.
