7. AI-generated content
FluentUp uses artificial intelligence (language models and voice synthesis) to generate conversations and feedback. Please be aware that:
- AI coach responses are automatically generated and may contain errors or inaccuracies.
- CEFR scores and feedback are indicative and do not constitute an official language certification.
- FluentUp is not a substitute for a professional language assessment or a formal educational program.
- Grammar corrections and vocabulary suggestions are AI-generated and should be taken as guidance, not as absolute reference.

All FluentUp content (design, code, 3D avatars, text, logos) is owned by Gonzalo Hafner Roda or its licensors and is protected by intellectual property laws.
Your content (session transcripts, progress data) belongs to you. You grant us a limited license to process and store that content solely for the purpose of providing the service.
9. Voice recordings
By using FluentUp, your voice is transmitted in real time to our voice technology providers for processing. We do not store audio recordings. We only retain the text transcript of conversations. For more information, see our Privacy Policy.

12. Modifications
We may modify these terms of use from time to time. When we do, we will update the “last updated” date and notify you of significant changes by email or through a notice in the application. Continued use of the service after notification constitutes acceptance of the new terms.
