Privacy Policy
This Policy explains how Riverstar Games (“we”, “us”) processes information when you use the Android game Knight’s Magic War (“Game”), package com.jcgame.materialMagic.global, and contact our support team.
1. Information we process
- Account and sign-in: verified Google OpenID and Google Play Games player identifiers, temporary server authorization codes, internal player ID, selected server, and in-game profile information. Authorization codes are used to verify sign-in; we do not receive your Google password.
- Gameplay: progress, heroes, troops, equipment, skills, inventory, virtual currency, rewards, battle results, in-game mail, settings, and related timestamps needed to operate and synchronize your game.
- Purchases: when in-app purchases are available and you make a purchase, product and order identifiers, purchase token or receipt, purchase status, and the player and server receiving the item. Google Play processes payment details; we do not receive your full payment-card or bank-account details.
- Analytics: Google Analytics for Firebase processes app-instance identifiers, device and operating-system information, language, app version, sessions, screen views, and interactions such as tutorials, battles, rewards, and virtual-currency use. It derives approximate location from masked IP addresses and may record purchase events such as product and price. Depending on device availability and collection settings, it can also collect the Android advertising ID. The Game does not show ads.
- Service and support: network and security logs, including IP address, request time, and errors; and your email address, messages, or attachments when you contact us. Preferences and limited account or session data are also stored locally on your device.
2. Why we use information
We use information to authenticate players, maintain accounts, save progress, provide online gameplay, verify and deliver purchases, respond to support requests, understand feature use, measure the effectiveness of campaigns promoting the Game through Google Ads, improve reliability, detect fraud or cheating, and meet legal obligations. Where a legal basis is required, we rely on providing the requested service, legitimate interests in operating and protecting it, legal obligations, or consent where required.
3. Providers and disclosures
We use Google Play Games Services for authentication, Google Play for distribution and payment processing, Google Analytics for Firebase for usage analysis, and hosting providers to operate our servers. Providers process relevant information to deliver these services. Google may also process information under its own terms and privacy practices.
We link Firebase Analytics with Google Ads to analyze campaign results and measure installations, purchases, and other in-game actions. Relevant analytics data, including app-instance or advertising identifiers, approximate location, app interactions, gameplay events, and purchase events, may be shared with Google Ads for analysis and advertising measurement according to the linked-service settings. This association does not add advertising placements to the Game. We do not send your Google password, full payment-card details, or raw game-account credentials to Analytics or Google Ads.
See the Google Privacy Policy and Firebase privacy information. We may disclose necessary information to comply with law, protect players and the service, resolve disputes, or handle a business transfer with appropriate protections. We do not sell personal information for money or use it to display targeted advertising in the Game.
4. Retention
Account and gameplay data is kept while needed to provide your account and the Game. Support and technical records are kept as needed to resolve issues and protect the service; analytics data is subject to the configured retention settings of the analytics service. Limited transaction, security, dispute, or legal records may be retained longer where required by law or reasonably necessary for those purposes. We delete or de-identify data when it is no longer needed.
5. Deletion, choices, and rights
You can request deletion of your game account and associated data, or request deletion of specific information, by following our Account and Data Deletion Instructions. You do not need to reinstall the Game to make a request. Uninstalling the Game only removes local data and does not automatically delete server records.
You can manage Google permissions through your Google Account and advertising-ID controls through Android settings. Depending on your location, you may have rights to access, correct, copy, delete, restrict or object to processing of your information, withdraw consent where processing relies on consent, or complain to a data protection authority. Contact us to exercise applicable rights. We may verify account ownership before acting.
6. Security and international processing
We take reasonable measures designed to protect information and limit access. No transmission or storage system is completely secure. Our servers and service providers may process information outside your country. Where required, appropriate safeguards apply to international transfers.
7. Younger players
The Game is intended for players aged 13 and over and is not directed to children under 13. Where local law requires a higher age or parental permission for particular processing, those requirements apply. If you believe a child has provided information in violation of these requirements, contact us so we can investigate and delete it where appropriate.
8. This website and policy updates
This policy website does not embed analytics or advertising scripts. It is hosted on GitHub Pages, whose provider may process technical access logs under the GitHub Privacy Statement. We may update this Policy as features or practices change, revise the effective date, and provide further notice where required.
