Privacy Policy

This policy explains what information the site processes, why it is used, and the choices available to visitors.

Effective and last updated: July 26, 2026

Information processed

• Test activity: selected track, answers, estimated results, missed words, and test history.
• Browser storage: the site stores account display data, test history, and saved words in local storage under the keys vt_user, vt_history, and vt_words.
• Account data: if you create or use an account, the site processes the email address, display name, join date, saved words, and test history you provide.
• Email delivery: when you request a vocabulary report by email, the destination address and report content are sent to the email delivery provider for that request.
• Analytics: Google Analytics may receive device, browser, approximate location, page-view, and interaction data through cookies or similar identifiers.
• Technical logs: hosting and API providers may process IP addresses, request times, user agents, and error information for security and service operation.

Purposes and legal basis

Data is used to provide the test, remember progress, synchronize signed-in accounts, send requested reports, measure site usage, prevent abuse, and maintain reliability. Depending on location, processing may rely on performing a requested service, legitimate interests in operating and securing the site, consent for non-essential analytics, or compliance with legal obligations.

Storage and retention

Local-storage data remains on the device until it is cleared by the visitor or removed through browser controls. Account data may be stored in the site database while the account remains active. Email delivery providers may retain operational delivery records under their own policies. A fixed deletion schedule has not yet been implemented; deletion requests are handled through the contact address below.

Service providers

The current implementation may use Netlify for hosting and serverless functions, MongoDB for synchronized account data, Google Analytics for usage measurement, and Resend for requested email delivery. These providers process information under their own terms and privacy documentation.

Your choices and rights

You can use the test without creating an account, clear browser storage, block analytics through browser or consent controls, and avoid the email-delivery feature. Depending on applicable law, you may request access, correction, deletion, restriction, objection, or data portability.

Children

The service is a general educational tool and is not designed to collect personal information from children without appropriate adult authorization. A parent or guardian who believes a child submitted personal data may request its deletion.
