Privacy Policy

1. Information we collect

Depending on how you use Nevilix, we may process the following categories of information:

• Account information: information you provide when creating or managing an account, such as your name, email address, and account preferences.
• Learning activity: lesson progress, quiz activity, answers, scores, completed learning items, weak-area indicators, and other study progress generated while you use learning features.
• Technical information: IP address, browser type, device information, operating system, request URLs, timestamps, and security or diagnostic logs generated when you access the website.
• Cookie and local-storage data: identifiers, session information, preferences, and browser-side learning state used to keep features working and remember your progress.
• Communications: information you choose to provide when you contact Nevilix or send feedback.

We ask you not to submit sensitive personal information unless it is genuinely necessary for a feature you are using.

2. How we use information

We may use information to:

• operate, maintain, secure, and improve Nevilix;
• provide lessons, quizzes, grammar practice, listening tools, and personalized learning progress;
• authenticate users and protect accounts from abuse or unauthorized access;
• remember preferences and resume learning sessions;
• measure website performance, troubleshoot errors, and understand how features are used;
• prevent fraud, spam, automated abuse, and security incidents;
• comply with applicable legal obligations; and
• support advertising where advertising is enabled on the website.

3. Cookies and local storage

Nevilix may use cookies, browser local storage, and similar technologies for essential website functions, authentication, security, preferences, learning progress, analytics, and advertising.

Some browser-side progress may be stored locally on your device. Clearing browser data, using private-browsing mode, or changing devices can remove locally stored progress that has not been synchronized to an account.

You can control or delete cookies through your browser settings. Blocking essential cookies may prevent login, saved preferences, or other parts of Nevilix from working correctly.

5. Sharing of information

We may share limited information only when reasonably necessary for purposes such as:

• Service providers: hosting, security, infrastructure, analytics, communications, or advertising providers that help operate Nevilix.
• Legal requirements: responding to lawful requests, protecting rights and safety, enforcing applicable terms, or preventing fraud and abuse.
• Business changes: a merger, acquisition, restructuring, financing, or transfer of assets, subject to applicable privacy obligations.

We do not intentionally disclose account information to unrelated third parties for purposes that are unrelated to operating Nevilix except with your direction or where required by law.

6. Data retention

We retain information for as long as reasonably necessary to provide the service, maintain account and learning history, meet security and operational requirements, resolve disputes, and comply with applicable legal obligations. Different categories of information may have different retention periods.

7. Security

Nevilix uses reasonable technical and organizational safeguards designed to protect information against unauthorized access, alteration, disclosure, or destruction. No online service or data transmission method can be guaranteed to be completely secure.

8. Children's privacy

Nevilix is a general-audience learning service. We do not knowingly seek to collect personal information from children where parental or guardian consent is required by applicable law. If you believe a child has provided personal information in a way that requires removal or parental action, please contact us using the method described below.

9. International processing

Nevilix and the service providers used to operate the website may process information in countries other than the country where you live. Where applicable, we use appropriate measures to handle personal information in accordance with relevant legal requirements.

10. Your privacy choices and rights

Depending on your location and applicable law, you may have rights to request access, correction, deletion, restriction, portability, or objection regarding certain personal information.

You may also:

• manage cookies through your browser;
• manage personalized advertising through Google Ads Settings;
• clear locally stored learning data from your browser; and
• request account-related privacy assistance through Nevilix.

11. Third-party links and services

Nevilix may link to third-party websites or services. Their privacy practices are governed by their own policies. We encourage you to review those policies before providing personal information to a third party.

12. Changes to this Privacy Policy

We may update this Privacy Policy when our services, technology, advertising arrangements, or legal requirements change. The effective date at the top of this page indicates when this version became effective.
