Terms of Use for Noi

Last updated: October 15, 2026

These Terms of Use (“Terms”) apply to Noi, a language-learning application for Android (package name com.noi.learning). By downloading or using Noi, you agree to these Terms. If you do not agree, please do not use the app.

Your Account

You need an account to use Noi. You are responsible for keeping your sign-in details secure and for activity on your account. Please give accurate information when you create it.

Noi Premium Subscription

Some lessons are available only with a Noi Premium subscription. The current price is shown in the app before you buy.

• Billing. Subscriptions are sold and billed through Google Play, to the payment method on your Google account. Google Play's terms also apply to your purchase.
• Automatic renewal. Your subscription renews automatically at the end of each billing period (for example, each month) and you are charged again, unless you cancel before the renewal date.
• Cancelling. You can cancel at any time in the Google Play Store app (Profile → Payments & subscriptions → Subscriptions), or from “Manage subscription” in Noi's menu. After you cancel, you keep premium access until the end of the period you have already paid for. Uninstalling the app or deleting your account does not cancel the subscription.
• Refunds. Payments are handled by Google Play, and refunds follow Google Play's refund policies. We do not give partial refunds for unused time, except where the law requires it.
• Price changes. We may change the subscription price. Google Play will notify existing subscribers before a price increase applies to them, and in some cases you will need to accept the new price to keep your subscription.
• Your account, not your device. A subscription is linked to the Noi account you were signed in to when you bought it. Use “Restore purchases” in the app if premium lessons do not unlock on a new device.

Using Noi

We give you a personal, non-transferable right to use Noi for your own learning. Please do not:

• Copy, redistribute, or sell Noi's lessons, audio, images, or other content
• Try to unlock premium content without a subscription, or get around access controls
• Reverse engineer, interfere with, or overload the app or its servers
• Use Noi in a way that breaks the law or harms other people

Content

Noi's lessons, audio, images, and design belong to Noi or its licensors. We work to make the lessons accurate, but language content can contain mistakes, and Noi is a study aid, not a substitute for professional translation or instruction. We may add, change, or remove lessons and features over time.

Ending Your Use

You can stop using Noi at any time and ask us to delete your account (see the account deletion page). We may suspend or close an account that breaks these Terms.

Disclaimers and Liability

Noi is provided “as is” and “as available”. We do not promise that it will always be available, error-free, or suitable for a particular purpose. To the extent the law allows, Noi and its developer are not liable for indirect or consequential losses arising from your use of the app, and our total liability is limited to the amount you paid for Noi in the twelve months before the claim. Nothing in these Terms limits rights you have under consumer protection law that cannot be waived.

Privacy

Our Privacy Policy explains what information Noi collects and how it is used.

Changes to These Terms

We may update these Terms as Noi changes. Updates will be posted on this page with a new “Last updated” date. If a change is significant, we will tell you in the app. Continuing to use Noi after an update means you accept the updated Terms.
