Ad providers may process device information and ad activity even when gameplay works offline. Your privacy choices and the enabled SDKs determine the processing that applies.
The active advertising-network list, SDK data configuration and intended audience must be confirmed before this version takes effect. This draft does not certify the game’s implementation or Google Play compliance.
01 Scope & developer
This Privacy Policy explains how KEY STONE ltd, the business name of KEY STONE (HONG KONG) HOLDING COMPANY LIMITED (“we”, “us” or “our”), handles personal information in games that link to this version of the policy, related support communications and this website.
Our games use third-party advertising and mediation SDKs. Advertising features connect to online services, even where core gameplay can be played offline. Information may be collected directly by SDK providers; it does not have to pass through our own servers to fall within this notice.
Data practices depend on the game, version, SDKs enabled, device permissions, region and privacy choices. This version addresses advertising-supported releases. A previous offline release that contains no advertising SDK has different practices. New account, purchase or other data-processing features require an updated, game-specific disclosure.
02 Information processed
The following categories describe information used for gameplay, advertising and support. A particular release must disclose the categories it actually processes; this notice is not permission to collect every possible SDK field.
| Category | Examples & use |
|---|---|
| Game data | Settings, progress and scores stored on your device to operate the game. Device backups, where enabled, are controlled by your device or backup provider. |
| Advertising identifiers | Google Advertising ID, where available and permitted, to support ad delivery, measurement and advertising choices. |
| Connection information | IP address and network type for ad requests, security and approximate regional targeting. Approximate location can be inferred from an IP address; it is different from GPS location. |
| Device & app information | Device model, operating system, language, display information, app package/version and SDK version for compatibility, delivery and diagnostics. |
| Ad activity & diagnostics | Ad requests, impressions, clicks, timestamps, errors and relevant event records for measurement, troubleshooting and fraud prevention. |
| Privacy preferences | Consent or opt-out signals, including a consent string where supported, to communicate and apply your advertising choices. |
| Support correspondence | Your email address, message and attachments when you contact us, to answer your inquiry and handle privacy requests. |
Additional fields supported by a provider are not necessarily enabled in our games. Any use of sensitive permissions, additional identifiers, installed-app information or sensor data needs disclosure matching the actual release. We do not ask you to send passwords or sensitive documents in ordinary support requests.
03 Why information is used
- Operate game features, preserve local preferences and respond to player support inquiries.
- Request, select, deliver and display advertisements; support mediation between advertising sources.
- Measure ad delivery, performance and attribution, manage reporting and settlement, and avoid excessive repetition.
- Provide interest-based advertising where enabled and permitted by your choices and applicable law.
- Diagnose failures, protect services, detect invalid traffic and prevent advertising fraud.
- Record privacy choices, handle rights requests and comply with legal obligations.
Advertising measurement is distinct from a separate gameplay analytics service. An advertising SDK may process events even when a game does not include a standalone analytics SDK.
04 Advertising partners
Enabled advertising networks may receive information directly through their SDKs or through advertising requests. Some providers act as independent controllers for their own processing, rather than solely as our processors.
The active advertising networks vary by game and release. Relevant providers, their privacy policies and data practices must be identified for each release.
Advertising recipients can include mediation providers, enabled ad networks, advertisers, measurement or attribution providers and infrastructure or fraud-prevention providers, as needed for the purposes explained above. Provider policies supplement this notice; they do not remove our responsibility for the SDKs we integrate.
05 Consent & advertising choices
Where consent is required, the app must obtain it before the relevant SDK processing starts. Reading this policy, continuing to play or dismissing a notice does not by itself constitute consent. Consent must be specific, informed and capable of being withdrawn.
Use the game’s advertising privacy or consent controls where available to review or change your choices. You can also contact hamads007007@gmail.com for help, or use the relevant provider’s rights-request channel. Withdrawing consent does not affect processing that was lawful before withdrawal.
Your Android device may offer settings to reset or delete its advertising ID or manage advertising privacy. The available options depend on the operating-system version. These device controls do not necessarily delete information already held by advertising providers.
Declining personalized advertising does not necessarily remove all ads or all processing. Contextual ads can still require limited information for delivery, reporting, security or fraud prevention, subject to applicable law and any required consent. A non-personalized ad is not automatically a “no data collected” ad.
Where European or UK law applies, consent is used where required for advertising identifiers, device access and personalized advertising. Other processing may rely on the necessity of providing a requested service, legitimate interests in support and security where permitted, or legal obligations. Where consent is legally required, a legitimate-interest claim does not replace it.
07 Retention & deletion
We retain information under our control only as long as reasonably needed for its stated purpose. Relevant factors include resolving a support case and follow-up, investigating fraud or disputes, and meeting applicable accounting or legal requirements. Information no longer required is deleted or anonymized. We do not prescribe a single retention period for every provider or data category.
Advertising and mediation providers apply their own disclosed retention criteria to information they independently control. See their policies and contact them for details or deletion requests. We cannot promise immediate deletion from all third-party systems.
To request deletion of information we hold, email hamads007007@gmail.com with the game name and the email address used to contact us. For an advertising-data request, we will explain what limited information is needed to locate records or route the request. Do not send a password. We will explain any lawful exception requiring continued retention.
Clearing app storage or uninstalling removes local game data in accordance with your device’s behavior and may erase progress. Backups may require separate removal. Uninstalling does not automatically delete advertising records already transmitted to providers.
For a game without accounts, there is no game account to delete, but privacy rights concerning SDK data still apply. If a game offers account creation, its account and associated-data deletion procedures must be available both within the app and through a designated external resource.
08 Children & younger players
A store content rating is not, by itself, a declaration of the game’s intended audience or its advertising configuration. Child-directed and mixed-audience games require age-appropriate disclosures, advertising and data handling.
Where a user is known to be a child, behavioral advertising and the use of personal information must be restricted in accordance with applicable law and platform requirements. Where parental consent is required, it must be obtained before the relevant processing; this policy does not replace parental consent or age-appropriate SDK controls.
If you are a parent or guardian and believe a child’s information has been processed improperly, contact hamads007007@gmail.com with the game name and your concern. We will investigate and take appropriate steps, including deletion or contacting the relevant provider where required.
09 Security & international transfers
We use reasonable administrative and technical safeguards appropriate to information under our control, including limiting access and protecting communications. SDK providers are responsible for the safeguards for their processing, and their practices must be assessed as part of integration. No internet transmission or storage system can be guaranteed completely secure.
We are based in Hong Kong. Advertising, hosting and email providers may process information in other countries with different privacy laws. Where required, international transfers must use an appropriate lawful mechanism, such as an adequacy decision or contractual safeguards. Contact us for information about safeguards relevant to your request; provider-specific details are available in their privacy notices.
10 Website & external services
This studio website does not itself embed the game’s advertising or mediation SDKs. Our authored pages contain no advertising or analytics scripts. The hosting service may process connection and security information needed to deliver the site; any hosting access service is governed by its own notice.
Externally hosted fonts and game imagery cause your browser to connect to their providers, which receive the information needed to deliver those resources. Google Play, advertisements and other external links lead to services governed by their respective privacy policies. Interacting with an advertiser’s website or installing another app can create separate processing outside our game.
If you email us, our email provider processes your message and attachments to deliver and store correspondence. Please provide only information relevant to your inquiry.
11 Policy updates
We update this notice when our services or data practices change. The current version and update date appear on this page. Material changes require appropriate additional notice and, where applicable, renewed consent before the new processing begins.
This draft is intended for advertising-supported game releases. It must be checked against the actual SDK build, enabled networks, target audience and consent experience before it becomes the applicable release policy.
