Oreumi

Terms of Service

Oreumi is operated by whatisvioletmustard (왓이즈바이올렛머스타드). Effective November 4, 2026.

1. The service

Oreumi provides Korean lessons, review tools and TOPIK practice tests. All lessons and questions are written by Oreumi. They are practice material, not an official TOPIK test, and we do not issue certificates. These terms are an agreement between you and whatisvioletmustard (왓이즈바이올렛머스타드).

2. Accounts

You must be at least 14 years old to create an account. You are responsible for keeping your login secure. One account works on the web and in our apps.

3. Subscriptions and payment

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders and handles customer service inquiries and returns related to payment. Subscriptions renew automatically until canceled. You can cancel at any time and keep Pro until the end of the period you paid for. Purchases made through the App Store or Google Play are billed and canceled through those stores.

See the refund policy.

4. Acceptable use

  • Do not copy, resell or redistribute lesson content or audio.
  • Do not try to break, overload or reverse-engineer the service.
  • Do not use the service to cheat in an exam.

5. Content and intellectual property

Lessons, audio and software belong to whatisvioletmustard (왓이즈바이올렛머스타드) or its licensors. Text you write stays yours; you allow us to store it to save your progress.

6. Changes and termination

We may update the service and these terms. We will tell you about material changes before they apply. We may suspend accounts that break these terms.

7. Liability

The service is provided as is. To the extent the law allows, our liability is limited to the amount you paid us in the 12 months before the claim. Nothing here limits rights you have under consumer law.
