Privacy Policy

We may collect account details you provide directly, including your email address, authentication identifiers, billing records, and support messages.

When you use the service, we may collect study preferences, selected exams, vocabulary lists, prompts, generated flashcards, example content, saved progress, usage logs, browser metadata, IP-derived security signals, and cookie or session identifiers needed to operate the product.

We use this information to operate vinext.org, generate vocabulary study materials, save your learning progress, prevent abuse, diagnose failures, improve reliability, and communicate about your account or support requests.

We may also use aggregated and de-identified usage information to understand product performance and demand across tools and workflows.

We use third-party infrastructure and AI service providers to run the product. Depending on the request, account data, prompts, vocabulary inputs, generated flashcards, example text, images, and other outputs may be processed by hosting, authentication, analytics, payment, storage, or language-model vendors acting on our behalf.

Those providers may process data under their own terms and privacy commitments. We choose providers that are commercially reasonable for operating the service, but their systems remain outside our direct control.

We keep operational records for as long as reasonably necessary to provide the service, maintain security, comply with legal obligations, resolve disputes, and enforce our agreements.

Retention periods may differ for account data, billing records, security logs, saved study sets, generated assets, and related outputs.

You can stop using the service at any time. If you want to request deletion of account-related information or have a privacy question, contact [email protected].

You may also control cookies and similar technologies through your browser settings, although some features may stop working correctly if essential cookies are disabled.

The service is not directed to children under 13. If you believe a child has provided personal information to us, contact us so we can review the request.

If you access the service from outside your local jurisdiction, you understand that information may be processed in other countries where our providers operate.

We may update this Privacy Policy from time to time. When we do, we will post the updated version on this page and update the effective date above.
