For the purpose of speech-to-text transcription, only audio data is transmitted to a third-party AI service provider located in the United States. (Please refer to the Trust Center (trust.fastinsight.ai) for the specific processors.)
4. Transcribed text, voice recordings, and video recordings are retained for the period specified by the User or as required by law. If no period is specified, the Company retains them only as long as necessary to provide the Service, to fulfil the research purpose, and to comply with applicable law. When the User deletes a study, the underlying files are also erased from the Company’s storage.

In such case, Articles 14 through 17 shall not apply to that User.
