Terms of Service

1. The service

Bellin is a service where users practice voice conversations with AI in a language they choose, and receive a learning report and review expressions after each call. Whether a call is possible and which models are provided may vary with the network, device permissions and provider status.

2. Users and accounts

Bellin may be used only by people aged 14 or older. By starting the service, you are deemed to have confirmed that you are 14 or older. The call partner is not a person but an AI voice, and the partner's name and photo are of a fictional person.

In the app, you must create an account by email verification or social login before starting your first call. The account is also used to continue your records on other devices and to link purchase history. Users must keep their account and authentication methods secure and must not use another person's account.

3. AI conversations and records

AI responses are for practice and are not professional legal·medical·financial advice. The AI partner does not engage in sexual content, explicit violence or instructions for dangerous or illegal activities, and partner or photo descriptions written by users are not used if they contain such content. By default, full call transcripts are not stored on the service's servers; the scope and retention period of the summaries·learning records·optional audio data that are stored follow the Privacy Policy.

4. Usage limits

For the stability and security of the service and the policies of providers, limits on the number of calls·model usage·individual features may apply. Abnormal automation, excessive requests and attempts to access other people's data may be restricted.

5. Paid services

Deleting your account does not cancel the automatic renewal of an App Store or Google Play subscription, so you must manage it separately in the store where you purchased it. In-app payments are processed by Apple (App Store) or Google (Google Play), and refunds are requested from that store (Apple: reportaproblem.apple.com; Google Play: refund request in your order history). Users under 19 (minors under Korean law) must have a legal guardian's consent before making a purchase.
