5. About AI Responses
AllLang's corrections, translations, and roleplay responses are generated by AI language models. AI is not perfect and may produce inaccurate or inappropriate responses.

7. Changes to and Suspension of the Service
The operator may change, add to, or discontinue part or all of the Service, and will give advance notice of material changes. The Service may be temporarily suspended due to force majeure events such as natural disasters, technical failures, or outages of third-party services (app stores, cloud infrastructure, etc.).
8. Limitation of Liability
To the maximum extent permitted by applicable law, the operator is not liable for:
- Damages arising from inaccuracies in AI responses
