Terms of use

Effective from 1 December 2026.

1. Introduction

The Cool English app and the website www.cool-english.online are operated by Kvintech solution, s.r.o., Company ID 24663379, Kostelní 78/15, 796 01 Prostějov, Czech Republic (“we”). By installing and using the app you agree to these terms and to the terms of the store you downloaded it from (App Store or Google Play).

2. Licence

We grant you a non-exclusive, non-transferable right to use the app and purchased courses for your own non-commercial learning. Recordings, texts and translations are protected by copyright and may not be copied, distributed or sold. For companies and schools we offer activation codes.

3. Free and paid courses

  • The app, the intro course and sample lessons are free.
  • Paid courses and bundles are one-time in-app purchases via the App Store or Google Play. They are not subscriptions.
  • The current price is shown in the app before purchase. Payment, taxes and refunds are handled by Apple or Google under their rules.
  • You can restore purchased courses on other devices signed in with the same Apple or Google account.

4. Activation codes

  • An activation code unlocks one product (a course or a bundle).
  • A code can be used only once, on one device. It may have limited validity.
  • A course activated with a code is tied to the app installation; after uninstalling or on another device it may not be restored.
  • Codes cannot be exchanged for money.

5. Downloading lessons

Recordings of paid courses are downloaded from our server. An internet connection is required to download; downloaded lessons work offline. The server checks that the device is entitled to the course.

6. Liability

We keep improving the app, but we can’t guarantee it will always be error-free and continuously available. Learning results depend on how regularly you study. To the extent permitted by law, we are not liable for damage caused by improper use of the app.

7. Personal data

How we process data is described in the Privacy policy.

8. Final provisions

These terms are governed by the laws of the Czech Republic, without prejudice to the rights granted to you as a consumer by the law of your country of residence. We may change these terms; the current version is always on this page. Please send questions to support@kvintech.com.
