The Company uses artificial intelligence in the following services to operate the Bots.

The Company uses the following data to operate the Bots and credits each source as its terms require.

• Earthquake and tsunami information from the Japan Meteorological Agency (気象庁): used to read earthquake and tsunami alerts aloud in servers whose main language is Japanese. The Company receives this information through P2P地震情報, relays only what the Agency has announced, and makes no forecasts of its own. Alerts may be delayed or not delivered, and the Company does not guarantee their accuracy or delivery.

5. Usage restrictions

The Company classifies and manages TTS according to its precision and performance.

The Company applies different usage policies by TTS category.

The following exceptions apply.

• Incidental inclusion of Bot TTS audio in a stream or recording
• However, the Bot's TTS must not address sensitive topics.
• A stream or recording in which the Company's Bot TTS audio accounts for one third or more is treated as a content production.
• If Bot TTS audio is included, captions or text must disclose that the voice is AI-generated and not a real person.
• If VOICEVOX voices are included, a credit in the form "VOICEVOX:character name" (e.g. VOICEVOX:ずんだもん) must also be shown in the video description or subtitles.
• Cases expressly permitted as exceptions by the Company's chief officer

VOICEVOX voices are also subject to the VOICEVOX terms of use and the terms of each character (voice library). Depending on the character, they may not be used for political or religious activities, adult content, or false or misleading content.

If a violation of the above provisions is confirmed, service may be restricted or suspended without prior notice.

6. Membership services

• The Company offers paid memberships including the Custom Voice feature.
• A server membership applies to the one server it was purchased for and lets every user on that server use Plus-tier voices.
• Which Bots a membership applies to depends on the product. Personal memberships and the Server Membership apply to all Bots; the Server Membership (Lite) applies to Yeonhong only. The Bots covered are shown at checkout and under Membership in the dashboard.
• Memberships renew automatically each billing cycle using the user's registered payment method. Cycles and amounts vary by product and are shown at checkout and under Membership in the dashboard.
• When payment is made, the Company informs the user of the amount, payment date, payment method, and next scheduled billing date. Discord settings may prevent delivery of the notice; the same information remains available under Membership in the dashboard.
• Users may cancel at any time through Dashboard → Membership → Status, using the same method as enrollment. The Company will not make cancellation more complicated than signing up.
• After cancellation, no further renewal charges apply, and the already-paid period remains available until expiry. The effects of cancellation and refunds are defined in the Refund Policy.
• Users may upgrade during their membership. Before charging, the Company displays the old and new prices, remaining credit deduction, actual charge, and new billing date, and obtains the user's consent.

This does not apply to damages caused by the Company's intent or gross negligence.

9. Interpretation
