Cookie Policy

v2.1

Last updated: July 31, 2026 · Effective: July 31, 2026

1. What Are Cookies

Cookies are small text files (typically 1-4 KB) stored on your device by your web browser when you visit a website. They act as a short-term memory for the web, allowing sites to remember your login status, preferences, and other functional information across page loads and browsing sessions.

Cookies can be session cookies (deleted when you close your browser) or persistent cookies (remain for a set period). Voxlio uses both types strictly for operational purposes.

Plain English: Cookies remember who you are and your settings so you don't have to log in or reconfigure preferences every time you visit. Voxlio uses them only for this purpose — never for tracking or ads.

2. How We Use Cookies

Voxlio uses cookies exclusively for essential functionality. We do not use cookies for analytics, advertising, tracking, or profiling. Our cookie philosophy is minimal: if it doesn't need a cookie, we don't set one.

Authentication

NextAuth.js session cookie keeps you logged in across pages. Required for all platform features including Speaking, Writing, Dashboard, and V-Coin system.

Security

CSRF tokens prevent cross-site request forgery attacks on authentication and form endpoints. Rate limiting protects against brute-force attempts.

Preferences

Your selected currency (UZS/USD) is stored in a cookie so the setting persists between visits. Optional — can be disabled via Cookie Preferences.

The AI Vocabulary feature sends the word you type to Groq Inc. for analysis. No cookies are set by this feature — the request is stateless.

3. Cookies We Set

Voxlio sets exactly 4 cookies. All are strictly necessary for platform operation.

5. LocalStorage vs Cookies

In addition to cookies, Voxlio uses the browser's localStorage API to store certain user preferences and data on your device. Unlike cookies, localStorage data is never sent to the server with HTTP requests and cannot be accessed across different websites.

Note: Your unique 8-digit User ID (voxlioId) is stored server-side in our database as part of your account record. It is not stored in cookies or localStorage.

You can clear localStorage at any time via your browser's Developer Tools (Application → Local Storage) or by clearing site data in browser settings. Clearing localStorage will not log you out — authentication is cookie-based.

6. Third-Party Cookies

When you use the optional Premium payment feature, you are redirected to Click (Click.uz) — a licensed payment processor in Uzbekistan. Click may set its own cookies on their payment pages for transaction processing, fraud prevention, and session management. We do not control these cookies.

No other third party sets cookies through Voxlio. We do not embed social media widgets, analytics scripts, advertising pixels, or fingerprinting scripts. Our page source is fully auditable.

7. Managing Cookies

You can control and manage cookies through your browser settings. Below are links to instructions for common browsers:

Important: Blocking essential cookies will prevent you from logging in and using the Voxlio platform. localStorage data can be cleared separately without affecting cookie-based authentication.

8. GDPR & CCPA Compliance

Voxlio is committed to compliance with data protection regulations including the General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), and the Uzbekistan Law on Personal Data.

GDPR (EU Users)

  • Data processed on lawful basis of legitimate interest & contract performance
  • No consent required for essential cookies
  • Right to access, rectify, erase, and port your data
  • Data stored in US/EU with standard contractual clauses

CCPA (California Users)

  • Right to know what personal information is collected
  • Right to request deletion of personal information
  • Right to opt out of sale of personal information
  • We do not sell personal information — ever

9. Policy Updates

We may update this Cookie Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Material changes will be communicated via email or platform notification. We encourage you to review this policy periodically.

This policy was last materially revised on July 31, 2026 to reflect Voxlio v2.1: full IELTS Reading practice (Cambridge Books 10–20) with automatic marking, and expanded Writing Library. Cookie usage is unchanged — only essential cookies and optional preference storage items.
