This Privacy Policy explains how Tran Duy Ngoc ("Wumarino," "we," "us," or "our") collects, uses, discloses, and protects information when you use the Wumarino mobile application and related services (the "App").

Wumarino is built on a foundation of "privacy by design." We are committed to transparency, and we do not sell your personal data to third parties. Your trust is our highest priority.

Information You Provide: Depending on how you use Wumarino, you may voluntarily provide contact information (such as your name and email address for support) and application-specific data (such as preferences, settings, and user-generated content). This data is used solely to provide and improve your experience within the App.

App Activity and Usage Information: We may process information about how you use the App, such as features you access, settings you apply, subscription events, and similar product-interaction information to improve the App's functionality.

Device, Diagnostics, and Technical Information: We and our service providers may process technical information such as device type, operating system, app version, installation identifiers, IP address, network information, language, time zone, crash reports, and diagnostic logs to ensure App stability and security.

Subscription and Purchase Information: Purchases and subscriptions in the iOS version are processed by the Apple App Store, and in the Android version by Google Play. Wumarino and our service providers may receive purchase and subscription information made available by the applicable app store. Wumarino does not receive or store your full credit or debit card number or CVV.

We use the information we collect to: provide and operate the core features of the App; respond to support requests and process privacy requests; manage subscription status; analyze App use to improve features and measure performance; detect, prevent, and respond to fraud, misuse, or security incidents; and comply with legal, tax, and regulatory obligations.

We do not sell your personal information. We may disclose information only to trusted service providers and platform partners that help us operate, secure, and support the App. Categories of recipients include: App stores and subscription-management providers; Analytics and product-improvement providers; Diagnostics and crash-reporting providers; and Hosting, storage, and backend-infrastructure providers.

We require all service providers to use your information only for authorized purposes and to provide protections consistent with this Privacy Policy and applicable law. We may also disclose information when required by law, to protect rights and security, or to enforce our Terms.

The App may provide links to external websites, services, or resources. Those websites are operated by third parties under their own terms and privacy policies. Wumarino does not control those third-party websites, and any information you enter on a third-party website is governed by that third party's privacy practices.

You are in control of the data you choose to enter into the App. You may delete this data at any time through the App's settings. On iOS and Android, you can manage or disable notifications and permissions through your device settings. You can also manage your subscription directly through your Apple App Store or Google Play account settings.

We retain personal information for as long as reasonably needed to provide the App's features, manage subscriptions, ensure security, and comply with legal and accounting requirements. You may contact us to submit a privacy or deletion request. Please note that deleting the App from your device does not automatically delete information already collected by Wumarino or our service providers, nor does it cancel an active subscription.

We use reasonable administrative, technical, and organizational measures designed to protect your personal information. Information transmitted by the App is sent using encrypted connections. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.

Depending on where you live, you may have additional rights regarding your Personal Information. Subject to applicable law, you may have the right to confirm whether we process your data, access or obtain a copy, correct inaccurate information, delete certain information, obtain a portable copy, opt out of certain sales or targeted advertising, and not be discriminated against for exercising these rights.

To submit a privacy request, email caodinhcong9888@icloud.com with the subject line "Privacy Request." Describe the right you want to exercise and provide enough information for us to verify your identity.

For users in the European Economic Area or the United Kingdom, Tran Duy Ngoc is the controller of personal information where applicable. You may contact us at caodinhcong9888@icloud.com. Subject to applicable law, you may have rights to access, correct, delete, restrict, object to processing, receive portability of, or withdraw consent for certain personal information.

We and our service providers may process information in various countries around the world. Where GDPR or similar laws apply and personal information is transferred outside the EEA or another protected jurisdiction, we use appropriate safeguards where required, such as standard contractual clauses or other lawful transfer mechanisms.

The App is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided personal information to the App, contact us immediately at caodinhcong9888@icloud.com.

We may update this Privacy Policy from time to time. When we update it, we will revise the content. If changes are material, we may provide additional notice as appropriate.

If you have questions about this Privacy Policy, privacy requests, support, or deletion requests, contact us at caodinhcong9888@icloud.com.
