Privacy Policy

Last updated: May 22, 2026

xDev Asia ("xDev", "we", "our", or "us") operates the website https://blog.xdev.asia, related online services, and mobile applications published by xDev Asia, including educational apps and games. This Privacy Policy explains what information may be collected, how it is used, and what choices you have.

1. Information We Collect

The information we collect depends on how you use our website, services, or apps.

1.1 Information You Provide

When a feature requires an account or direct contact, we may collect information you provide, such as:

Name or display name
Email address
Profile information, if you choose to add it
Support messages or other information you send to us

Some xDev Asia apps do not require an account and do not ask users to provide personal information.

1.2 Website and Service Usage Data

When you use our website or online services, we may collect technical and usage data, such as:

Device type, browser type, operating system, and language settings
IP address and approximate location derived from IP address
Pages viewed, links clicked, referring URLs, and access times
Course progress, bookmarks, quiz results, or similar learning activity when those features are available
Error logs, performance data, and diagnostics

1.3 Mobile App Data

Our mobile apps may store app progress locally on your device, such as game score, settings, stars, streaks, or completed activities. In apps that do not use an account, this local progress is not automatically sent to xDev Asia servers.

Some apps may use third-party services such as Google AdMob for advertising. These services may collect or process data according to their own policies and SDK behavior, including technical identifiers, advertising data, product interaction data, approximate location, crash data, performance data, and diagnostics.

2. Cookies, Analytics, and Advertising

Our website may use cookies or similar technologies to keep the site working, remember preferences, measure traffic, improve content, and show ads.

We may use third-party services including:

Google Analytics or similar analytics tools
Google AdSense for website ads
Google AdMob for mobile app ads
Firebase or similar infrastructure for authentication, data storage, performance, or diagnostics when needed
Hosting, CDN, email, payment, or support providers

Where applicable, apps designed for children are configured to avoid personalized advertising and to use child-directed or under-age treatment settings available in the advertising SDK.

3. How We Use Information

We use collected information to:

Provide, operate, and improve the website, services, and apps
Save user preferences and progress where a feature supports it
Respond to support requests
Monitor security, prevent abuse, and fix technical issues
Understand usage patterns and improve content or product quality
Show and measure advertising where ads are enabled
Comply with legal obligations

4. Sharing of Information

We do not sell personal information. We may share information only in limited cases:

With service providers that help us operate the website, services, apps, analytics, ads, hosting, payment, email, or support systems
When required by law, regulation, legal process, or government request
To protect the rights, safety, property, or security of xDev Asia, our users, or the public
In connection with a business transfer such as merger, acquisition, or asset sale

Third-party services process information according to their own privacy policies.

5. Children's Privacy

Some xDev Asia mobile apps may be designed for children or family use. We do not knowingly ask children to provide personal information in those apps. If a parent or guardian believes a child has provided personal information to us, please contact us and we will review and delete it where appropriate.

For child-oriented apps that include ads, we configure available advertising settings to limit ad personalization and use child-appropriate treatment where supported.

6. Data Retention

We keep information only as long as needed for the purposes described in this policy, unless a longer retention period is required by law. Local app progress stored on your device can usually be removed by deleting the app or clearing app data from the device settings.

7. Data Security

We use reasonable technical and organizational measures to protect information. However, no method of transmission or storage is completely secure, so we cannot guarantee absolute security.

8. Your Choices and Rights

Depending on your location, you may have rights to access, correct, delete, export, or object to certain processing of your personal information.

You can also:

Manage cookies and tracking controls in your browser settings
Use operating system settings to reset advertising identifiers or limit ad tracking where available
Delete local app data by uninstalling the app or clearing app storage
Contact us to request deletion of account-related data, where applicable

9. Third-Party Links

Our website, services, or apps may link to third-party websites or services. We are not responsible for the privacy practices of those third parties. Please review their policies before using their services.

10. Changes to This Policy

We may update this Privacy Policy from time to time. The latest version will be posted on this page with an updated "Last updated" date.
