About this policy

Idle System Inc. provides MILLions. This policy explains the data collected through the game, its cloud backup, advertising, in-app purchases, and feedback feature.

Data collected during normal use

Cloud backup and authentication

When a network connection is available, MILLions automatically attempts to authenticate through Firebase and back up your game save. Firebase creates an anonymous authentication account with a unique user identifier. The backup contains game progress, game state, and purchase entitlements stored in the save. These identifiers and data support authentication and cloud backup.

You do not need to enter a name, email address, username, or password for this automatic authentication. “Anonymous authentication” describes the sign-in method: the identifier still distinguishes your game records. The app currently has no setting to turn off automatic cloud backup.

Usage analytics and diagnostics

The game sends an identifier generated for your installation, app and device information, language, activity timestamps, game progression, session activity, and interactions with game features, advertisements, and purchases. It also sends crash and error information, stack traces, hang information, and other performance diagnostics. We use this information to understand how the game is used, investigate problems, and improve the game.

Installation identifiers are pseudonymous identifiers that allow records from the same installation to be associated. They do not make the collected records fully anonymous. Analytics and diagnostic collection run automatically, and the app currently has no setting to turn them off.

Advertising

MILLions uses Google AdMob. Google's advertising SDK collects and shares IP addresses, which may be used to infer approximate location; app and ad interactions, such as launches, taps, and video views; diagnostic and performance information; and device or other identifiers, including the Android advertising ID and app set ID where available.

Google uses this data for advertising, analytics, and fraud prevention. Ad availability and the data used can depend on consent choices and device settings. Where the app presents an advertising consent form, you can make the choices offered there. Android also provides advertising ID controls in device settings.

Google describes its handling of advertising data in its Privacy Policy and its explanation of data from apps that use Google services.

Data from optional features

Linking a Google or Apple account

Linking a Google account or, on iOS, an Apple account is optional. If you choose to link one, authentication through that provider associates it with your game authentication account. We store your user identifier, account type, update timestamp, and email address if the provider supplies one, for authentication, account management, and cloud-save access. An email address supplied through Sign in with Apple may be an Apple private relay address. A supplied email address is stored rather than processed only temporarily. You can play as a guest without linking an account.

When you link a Google account, Google may also provide your profile name and profile photo URL, which Firebase Authentication processes and retains in the authentication profile associated with your user identifier for authentication and account management. The Google profile name is not automatically used as your public leaderboard name.

In-app purchases

You can play MILLions without making a purchase. If you choose to purchase an item, Google Play processes Android payments and Apple App Store processes iOS payments. The game receives purchase and entitlement information, records purchase activity, and stores the entitlement needed to provide the purchased feature. Purchase information stored in your game save can be included in automatic cloud backup. We use this information to provide purchased features and understand purchase activity.

We do not receive your payment card number or other payment details that you provide directly to Google Play or Apple App Store. The terms and privacy policy of the store you use govern its payment processing.

Apple Privacy Policy

Feedback

If you choose to send feedback, we collect the text you submit together with your installation identifier, app and device context, and language. Only if you choose to attach them on the feedback screen, we also receive your current save data and a screenshot of the game screen (the feedback form itself is not included). We use them to understand your report, reproduce problems, and improve the game.

Service providers and security

We use Google Firebase services to process and store authentication, cloud-save, analytics, and feedback data for us. Google AdMob processes advertising data as described above. Google Play and Apple App Store process purchases on their respective platforms.

Data sent by the game to these services is encrypted in transit using HTTPS or TLS. Encryption in transit protects the connection; the service receiving the data can process it.

Retention and deletion

We currently do not apply an automatic expiration period to the records that we manage for MILLions. These records remain stored until removed through an administrative operation. Data processed independently by Google or Apple, including advertising and payment data, is retained and deleted according to the applicable policies of that provider.

The app stores game data and identifiers on your device, and the services described above store the data sent to them. The in-app gameplay reset restarts game progression. It does not request deletion of the cloud authentication account, server-side analytics, feedback, or all previously uploaded records. Removing the app also does not by itself request deletion of server-side records.

For questions about privacy and data associated with MILLions, email idle.system.company@gmail.com and identify the game as MILLions. Do not send a password or payment card details.

Delete your MILLions account and associated data

You can request deletion of your MILLions account and the data associated with it. You can use the email contact below even if you have already uninstalled the app.

Email idle.system.company@gmail.com to request deletion

Use the subject “MILLions account deletion” and tell us that you want your MILLions account and associated data deleted. If you linked a Google or Apple account, provide the email address shared with the game, if available. This may be an Apple private relay address. Include your user ID if you already know it; you do not need to reinstall the app to find it. We may ask for additional information to identify the account and verify that you are its owner. Do not send passwords, authentication codes, or payment card details.

Requests cover the account and associated data that we manage, including authentication, account-management records, and cloud saves. After identifying the account and verifying ownership, we proceed with deletion. Deletion may prevent you from restoring your game progress from the cloud. Advertising and payment data that Google or Apple manages independently are subject to the applicable procedures and policies of that provider.
