This Privacy Policy explains how Wordinarius Echo handles information when you use the mobile apps or browser experience. For privacy questions, contact us at wordinariusapp@gmail.com.

Information We Handle

Speech Practice

Wordinarius Echo uses speech recognition so learners can practice speaking. The production learner flow is designed around on-device/platform speech recognition and app-side scoring of the recognized transcript. We do not use regular learner speech practice as a paid cloud-transcription workflow on our servers.

Your device operating system or speech-recognition provider may process speech input according to its own settings and policies.

How We Use Information

Service Providers

We use Firebase and Google Cloud services for authentication, backend functions, storage, and app infrastructure. We use Google AdMob for mobile ads and Google Ad Manager or Google AdSense for browser ads and advertising-related measurement. Premium payments are handled by the relevant app store, such as Google Play or the Apple App Store. Learn more about how Google uses information from sites and apps that use its services.

Advertising, Cookies, and Consent

Free learners may be offered an optional rewarded ad before protected content is unlocked. Premium access confirmed through a mobile store suppresses browser ad requests for that signed-in account. We do not provide a separate browser checkout.

Where required, Google's certified consent management platform asks for permission before advertising cookies, local storage, personalised ads, or related processing are used. You can reject non-essential advertising consent or change a previous choice from the browser app's Profile screen using “Privacy and cookie settings”. Google may also display an equivalent privacy settings link on eligible pages.

Younger Learners and Age-Appropriate Ads

Wordinarius Echo is a general-audience language-learning service designed primarily for teenage and adult learners; it is not directed specifically to children. Mobile ad requests are explicitly identified as not child-directed and remain limited to Google's General Audiences rating. Browser ad requests use an unspecified age treatment. Both mobile and browser advertising remain non-personalised, and sensitive, alcohol, gambling, weapon, and firearm ad categories remain blocked for the Wordinarius Echo inventory.

A parent or guardian should supervise a child's use and provide any authorization required by local law before an account is created or personal information is submitted. Advertising safeguards reduce risk but cannot replace parental supervision or the controls provided by the device and app stores.

Data Sharing

We do not sell your personal information. We share information only as needed to run the app, verify ads or purchases, provide support, comply with legal obligations, prevent abuse, or work with service providers that operate the app infrastructure.

Data Retention and Deletion

We keep account and learning information while your account is active or as needed to provide the app. You can delete your account from the app profile screen in the release app. If you cannot access the app or the deletion action is not available in your current version, you can request deletion by email at wordinariusapp@gmail.com.

Some records may be retained when needed for security, fraud prevention, legal compliance, accounting, purchase verification, or dispute handling.

Security

We use Firebase and Google Cloud security controls, backend-owned entitlement checks, and restricted access boundaries to protect account, progress, premium, rewarded-unlock, and content-delivery data.

Changes

We may update this policy when the app, legal requirements, or service providers change. The updated policy will be posted on this page with a new date.
