Privacy Policy

Introduction

Welcome to Ukuku World, operated by HahaStudio OÜ ("HahaStudio OÜ", "Ukuku World", "we", "our", or "us").

Ukuku World is a children's storytelling and relaxation app featuring interactive characters, bedtime stories, calming sounds, emotional learning experiences, and gentle games designed primarily for children ages 3–8.

We care deeply about privacy and safety, especially for children. This Privacy Policy explains what information we collect, how we use it, how we protect it, and the choices available to parents and guardians.

Children's Privacy

Ukuku World is designed for children and families. We are committed to complying with applicable children's privacy laws and regulations, including the Children's Online Privacy Protection Act ("COPPA") where applicable.

Certain features, such as interactive conversations with characters, may involve the collection and storage of user-provided text in order to provide the functionality of the app.

By creating an account or allowing a child to use the App, a parent or guardian represents that they consent to the collection and use of information as described in this Privacy Policy.

We encourage parents and guardians to supervise children while using the app.

We do not sell personal information and do not use children's data for third-party advertising or advertising tracking purposes.

Information We Collect

Information Provided by Parents or Users

Depending on how the app is used, we may collect:

• Email address (for account creation, login, support, and account management)
• Child nickname or preferred display name used for personalization within the app
• Child's birthday date (for personalization - to send birthday greetings)
• Messages and conversation content shared with Ukuku World characters
• Account preferences and settings

AI Conversations

Ukuku World includes interactive character conversations powered by AI technologies.

To provide these experiences, we may:

• process conversation messages using third-party AI providers such as OpenAI
• store conversation history and AI-generated summaries in secure cloud databases
• use stored context to maintain continuity and personalization within the app experience

These conversations are used solely to provide and improve the app experience and are not used for advertising purposes.

Interactive conversations are generated automatically by AI systems and may occasionally produce unexpected or inaccurate responses despite our safeguards.

AI Safety and Moderation

Ukuku World is designed to provide child-friendly and age-appropriate experiences.

We use moderation systems, safety filters, and internal safeguards intended to reduce harmful, inappropriate, or unsafe AI-generated responses during interactive conversations with characters.

These systems may include automated moderation technologies, content filtering, and behavioral limitations applied to AI-generated interactions.

However, AI-generated content may not always be perfect, and we encourage parents or guardians to supervise children while using interactive features.

If you believe inappropriate content was generated within the app, please contact us at:support@ukukuworld.com
