Privacy Policy

Last updated: August 26, 2026

CraDiff Studio (“CraDiff”, “we”, “us”, or “our”) respects your privacy and is committed to protecting the information of users who use our mobile games, applications, websites, and related services (collectively, the “Services”).

This Privacy Policy explains what information may be collected when you use our Services, how we use that information, and the choices available to you. We aim to collect only the information reasonably necessary to operate, maintain, improve, analyze, and support our Services.

1. Information We Collect

The information we collect depends on the CraDiff game, application, or service you use and the features you choose to use.

We may collect or process the following categories of information:

Account information that you voluntarily provide, such as a username and authentication information.
Gameplay and app activity information, such as game progress, levels started or completed, achievements, battle results, gameplay statistics, and interactions with game features.
Device and technical information, such as device type, operating system, app version, language, device or advertising identifiers, and general technical information about the device or application.
App performance information, such as crash reports, diagnostics, errors, and other information used to identify and resolve technical problems.
Approximate location information, which may be derived from information such as an IP address or provided by third-party advertising or analytics services.
Purchase and transaction information related to in-app purchases or subscriptions. Payment processing is generally handled by the applicable app store or payment provider, and CraDiff does not directly receive or store your full payment card information.
Feedback or other messages that you voluntarily submit through our games, applications, websites, or support channels.

Not every CraDiff Service collects every category listed above. The information collected depends on the features available in the particular Service and the third-party services integrated into it.

2. Account Information

Some CraDiff games may allow you to create an optional account. Depending on the game, account information may include a username, password or other authentication information, and game data associated with that account.

Account information may be used to authenticate users, save game information, restore or synchronize game progress, and provide account-related functionality.

Where account registration is optional, you may continue to use the features that do not require an account without registering, subject to the functionality available in the particular game.

3. Gameplay and Battle Data

We may collect gameplay information in order to operate game features, understand how our games are used, balance gameplay, improve game design, and provide game-related functionality.

This information may include level progress, gameplay results, completion or failure events, scores, achievements, game mode activity, and similar gameplay information.

Some CraDiff games may include Battle or similar competitive game modes. These modes may use gameplay records or historical gameplay results stored on our servers to provide asynchronous competition between players. For example, a player’s gameplay result may be compared with a historical gameplay result from another player.

Where applicable, gameplay information associated with registered accounts may be stored on our servers to support account functionality and game features.

4. Analytics

We may use analytics services, including Google Analytics for Firebase or similar services, to understand how users interact with our games and applications.

Analytics information may include:

App opens and sessions;
Gameplay progression;
Levels started, completed, or failed;
Interactions with game modes and features;
Advertising-related events;
App version and device information;
Crash, diagnostic, and performance information; and
Other app usage events.

We use this information to analyze performance, identify problems, understand how our Services are used, improve gameplay, evaluate features, and improve the overall user experience.

5. Feedback and User Communications

Some CraDiff games and applications may provide an in-game feedback or support feature.

If you choose to use this feature, we may collect the content of the message that you voluntarily submit. Providing feedback is optional and is not required to use the normal gameplay features of our games unless otherwise clearly stated.

We may use feedback messages to understand user concerns, identify bugs or technical problems, evaluate game features, improve our games and Services, and provide support where a method of contacting the user is available.

Please avoid including sensitive personal information in feedback messages unless it is necessary for your support request.

6. Advertising

Many of our games are supported by advertising. We may use third-party advertising networks, advertising platforms, and mediation services to display advertisements in our games and applications.

These third-party services may collect or process information such as device information, advertising identifiers, IP address, approximate location, app activity, advertisement interactions, and other technical information in accordance with their own privacy policies and applicable law.

Depending on your location, device settings, consent choices, and applicable law, advertisements may be contextual, non-personalized, or personalized.

Where required by applicable law, we or our advertising partners may request your consent before using certain information for personalized advertising or related purposes.

You may also be able to control certain advertising preferences through your device settings, operating system settings, consent options presented within our applications, or settings provided by the relevant advertising provider.

Choosing non-personalized advertising or limiting advertising tracking does not necessarily prevent advertisements from being displayed. It generally affects how advertisements are selected or personalized.

7. In-App Purchases and Subscriptions

Some CraDiff games may offer in-app purchases or subscriptions.

Purchases made through platforms such as Google Play or the Apple App Store are processed by the applicable platform provider. CraDiff may receive information about a transaction, such as the product purchased, transaction status, purchase entitlement, or subscription status, where necessary to provide purchased content and manage game functionality.

CraDiff does not normally receive or store your full credit card or other payment card details when purchases are processed by an app store.

8. How We Use Information

We may use information collected through our Services to:

Provide and operate our games, applications, and related Services;
Save and manage game progress and account information;
Provide gameplay, Battle, reward, and other game features;
Analyze gameplay and app usage;
Improve game design, balance, features, and user experience;
Detect and resolve bugs, crashes, and technical problems;
Display and measure advertisements;
Process and verify in-app purchase entitlements;
Receive and evaluate user feedback;
Provide customer support;
Protect our Services against abuse, fraud, or security threats; and
Comply with applicable legal obligations.

9. Third-Party Services

Our games and applications may use third-party services for functions such as advertising, analytics, crash reporting, app distribution, purchases, and other technical services.

These third parties may process information according to their own privacy policies. Depending on the particular CraDiff game or application, third-party services may include services provided by Google, Firebase, Google AdMob, Unity, advertising mediation partners, app stores, and other service providers.

The third-party services used may vary between our games and may change over time as we update our Services.

10. Sharing of Information

We do not sell your personal information.

Information may be processed or shared with service providers where necessary to operate our Services, including providers of analytics, advertising, hosting, technical infrastructure, app distribution, payment processing, and other services.

We may also disclose information where reasonably necessary to comply with applicable law, legal process, governmental requests, enforce our agreements, investigate fraud or security issues, or protect the rights, safety, and property of CraDiff, our users, or others.

11. Data Retention

We retain information only for as long as reasonably necessary for the purposes described in this Privacy Policy, to provide our Services, to comply with applicable legal obligations, or to resolve disputes.

Retention periods may vary depending on the type of information and the game or Service involved.

Some information may be deleted or anonymized when it is no longer reasonably necessary for the purposes for which it was collected.

12. Data Security

We take reasonable administrative, technical, and organizational measures designed to protect information against unauthorized access, loss, misuse, alteration, or disclosure.

Where appropriate, information transmitted between our applications and our servers is protected using secure network communication such as HTTPS/TLS.

However, no method of electronic transmission or storage can be guaranteed to be completely secure.

13. Children’s Privacy

Our Services may be available to users of different ages depending on the game, app store classification, territory, and applicable law.

We take children’s privacy seriously and seek to comply with applicable laws and platform requirements concerning children and younger users.

Where required, we may limit data collection, personalized advertising, or certain features based on age, region, consent status, or other applicable requirements.

If you are a parent or guardian and believe that a child has provided personal information to us in a manner that is inconsistent with applicable law, please contact us using the information provided below.

14. Your Privacy Choices and Rights

Depending on where you live, applicable privacy laws may provide you with certain rights regarding your personal information. These may include rights to request access, correction, deletion, restriction, or other actions relating to your information.

You may also have choices relating to advertising personalization, analytics, or consent through settings provided by your device, operating system, application, app store, or third-party service provider.

If a CraDiff game provides an account deletion feature, you may use that feature to request deletion of the applicable account and associated information, subject to information that we are permitted or required to retain under applicable law.

You may also contact us to make a privacy-related request.

15. Cookies and Website Information

Our websites may use cookies or similar technologies to provide website functionality, remember preferences, understand website usage, or support other website features.

You can configure your browser to refuse or delete cookies. Disabling cookies may affect certain website functionality.

16. International Users

CraDiff provides games and Services to users in multiple countries and regions. As a result, information may be processed in countries other than the country in which you live, including locations where our service providers operate.

Where required, we take reasonable steps to process information in accordance with applicable privacy and data protection laws.

17. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes to our games, Services, technology, third-party services, or legal requirements.
