Effective: July 15, 2026. Here's how we handle your data.

1. Introduction

Welcome to Zolttalk. This Privacy Policy describes how we collect, use, share, and protect information when you utilize our mobile application and related web platforms. By installing and interacting with Zolttalk, you agree to the processing methods explained herein.

2. Information We Collect

To provide high-quality language practice, we collect several categories of information:

  • - Account Information: Your name, email address, profile picture, and native language details, provided during sign-up.
  • - Voice and Speech Data: During Speaking Practice and Chat scenarios, audio records are submitted and transcribed to measure vocabulary, speed, and pronunciation accuracy.
  • - Writing Submissions: Standard essay drafts, phrases, and logs you enter into the writing practice or tests. Text you submit for practice and feedback.
  • - P2P Communication Logs: When matching for live voice calls, connection signals (such as secure WebRTC candidate metadata) are exchanged to establish voice streaming between peers.
  • - Device and Usage Information: Operating system version, session duration, and gamified progress indicators.

3. How We Use Your Information

We process your data for the following essential business purposes:

  • - To match you with compatible language peers and handle real-time WebRTC audio calls.
  • - To evaluate your speaking and writing tests, giving detailed score breakdowns and correction reports.
  • - To manage your learning stats, streaks, level-ups, and display ratings on the global Leaderboard.
  • - To detect, prevent, and moderate offensive behavior, harassment, or violations of our community standards.
  • - To process premium upgrades and handle subscription cancellation requests.

4. Peer-to-Peer (P2P) Communication Privacy

Live matching calls on Zolttalk utilize Peer-to-Peer protocols. Audio streams are routed directly between users where possible, minimizing server transit. We do not record or store your live conversations with other humans on our servers.
