Terms of use

Effective October 5, 2026. These terms cover Yuna, an AI companion app for children that is set up and supervised by a parent or carer, and its website, yunasworld.com. Yuna is available on iPhone, iPad, Android, Samsung Galaxy and Amazon Fire devices from the Apple App Store, Google Play, the Samsung Galaxy Store and the Amazon Appstore. Features can differ slightly between devices and may change as we improve the app. Yuna and yunasworld are provided by Baseone Innovations ("we", "us").

Family accounts

A Yuna family account must be created by an adult parent or legal guardian, who is responsible for the account, its child profiles and any grown-ups they invite to the family. Keep your sign-in details and parent PIN private. Children use Yuna through the profiles their grown-up creates; they should not create accounts or make purchases themselves.

Downloading from an app store

These terms are between you and us, not the app store. When you download Yuna, the terms of the store you use also apply: Apple's Licensed Application End User License Agreement for the App Store, the Google Play Terms of Service for Google Play, the Samsung Galaxy Store terms for the Galaxy Store, and the Amazon Appstore terms for the Amazon Appstore. If these terms conflict with the store's terms on how the app is licensed to you, the store's terms apply.

Plans, subscriptions and purchases

Yuna is free to download. Optional Premium and Premium Plus subscriptions and in-app purchases are sold through the store you downloaded Yuna from, which takes payment and manages billing. Subscriptions renew automatically at the end of each period at the price shown in the app unless you turn off auto-renew at least 24 hours before the period ends. You can manage or cancel a subscription in your Apple, Google Play, Samsung or Amazon account settings; Yuna keeps working until the end of the period you have paid for. Refunds are decided by the store under its own policies. Monthly AI activity allowances are part of a plan, are shared across the family's child profiles, have no cash value and do not carry over.

Using Yuna and the website

You may use Yuna and the website for personal, non-commercial family purposes. You must not try to disrupt them, gain unauthorised access, introduce harmful code, get around safety features or usage limits, or misuse their content or features.

AI content and safety

Yuna's replies, stories and creations are generated by AI and checked by safety filters, but they can occasionally be wrong or unsuitable. Yuna is not a substitute for a parent, teacher or professional, and is not medical, legal or emergency advice. Grown-ups should supervise use through the Grown-ups dashboard. Optional features such as Yuna Explore and Family Safety location stay off unless a grown-up switches them on. Please report any concern through Help & Support.

Trade marks and other brand assets

The yunasworld name, the Yuna name and character, our logos, artwork, and other original brand assets and content belong to us or are used with permission. Using Yuna or this website does not give you any licence or right to use them. Please do not copy, publish, sell, imitate, or reuse them without our prior written permission.

Trademark notices

Apple, the Apple logo, iPhone, iPad and CarPlay are trademarks of Apple Inc., registered in the U.S. and other countries. App Store is a service mark of Apple Inc., registered in the U.S. and other countries. IOS is a trademark or registered trademark of Cisco in the U.S. and other countries and is used under license.

Google Play and the Google Play logo are trademarks of Google LLC.

Availability and responsibility

We aim to keep Yuna and the website accurate and available, but features may change and the service may occasionally be unavailable. Nothing in these terms limits any rights or responsibilities that cannot legally be limited, including your statutory consumer rights. We are not responsible for losses that were not reasonably foreseeable or for events outside our reasonable control.

Ending use

You can stop using Yuna at any time and delete the family account in Grown-ups dashboard → Account. Deleting the account does not cancel a store subscription, so cancel that with the store too. We may suspend or close an account that breaks these terms or puts children at risk.

Privacy

Our privacy policy explains what information Yuna and the website collect, how it is used, and how to request access or deletion.

Changes and contact

We may update these terms as Yuna develops. The effective date above shows when they last changed, and we will tell you in the app before a significant change applies. Questions can be sent to hello@yunasworld.com.
