Cookie Notice

Effective October 16, 2026

This notice explains cookies and similar storage we use on NativeTrainer: Chinese Tones. It is part of our Privacy Policy.

Essential cookies (always on)

These are required to sign in, keep you signed in, complete website checkout, and protect the site. The paid website product cannot work without them. We do not ask for opt-in for these.

  • Clerk: session and security cookies for authentication.
  • Freemius: cookies needed to open website checkout and return you after payment (website purchases only — not used for Google Play Billing in the Android app or Apple In-App Purchase in the iOS app).
  • Hosting (Vercel): cookies or headers used for security and routing.

On-device preferences (not advertising)

We store a few flags in localStorage on your device, not as third-party ad cookies:

  • Language (English / 中文 / other languages you pick).
  • Whether you dismissed this cookie notice.
  • Optional pack completion progress where those tracks are used.
  • Trainer level clears and review favorites (also synced to our database when you are signed in).

Advertising measurement (optional, website only)

If you tap Accept on the cookie banner, the website loads Google Ads (tag AW-18169314342) to measure visits that come from our ads. That can set a Google conversion cookie. If you tap Decline, the tag is not loaded. The iOS and Android apps do not include this tag. You can change your choice by clearing site data for this website and answering the banner again.

What we do not use

We do not sell cookie data. We do not load advertising tags inside the iOS or Android apps. The website Google Ads tag above runs only after you accept.

How to control cookies

You can block or delete cookies in your browser. If you block essential cookies, sign-in and website payment may fail. Questions: obeulah36@gmail.com. See also the Privacy Policy.
