Privacy Policy

Last updated: November 8, 2026

EnglishGlow is an English vocabulary-learning website. This policy explains the information the website is designed to use. Before publication, the site operator must verify this policy against the live website and its service settings.

Information used by the website

If you create an account, EnglishGlow uses account information such as your email address and authentication details through Supabase Authentication. The website may also use a display name if you provide one.

When you mark vocabulary words as learned or for review, EnglishGlow stores your word-progress status in a Supabase database associated with your account.

Why this information is used

Account information supports sign-in and account access. Word-progress information lets you view your learning progress and review words across sessions.

Service providers

EnglishGlow uses Supabase for authentication and storage of learning progress. Supabase may process information according to its own service documentation and applicable agreements.

Browser storage and cookies

Authentication services may use browser storage to maintain a signed-in session. The operator must confirm whether any additional analytics, advertising, or third-party cookies are used before publishing this policy.

Microphone access

If you choose the voice-answer feature in Runner 3D, your browser may request microphone permission and use browser speech-recognition functionality. The availability and handling of speech recognition depend on your browser and its provider. You can choose to type answers instead.

Data access and retention

Word-progress records are intended to be accessible only to their associated signed-in account through database access controls. Retention periods and account-deletion procedures must be confirmed by the operator before launch.

Your questions and requests

To ask about your information or request account/data deletion, use the Contact page. A working contact method must be added before public launch.

Changes

This policy may be updated when the website or its services change.
