  1. The developer refers to a free trial, but does not document its length, who offers it or whether payment details are needed; it is presumably arranged by the provider. My Voices is excluded during the trial.
  2. A hearing-care professional must create the account before app use. Exercise content does not establish clinical benefit.
  3. The developer's system requirements call for a stable connection (10 Mbps or more recommended) during training. They do not explicitly say training is impossible offline, and they do not document an offline mode.
  4. Only for the optional My Voices feature. A family member or friend records a voice sample through an invitation link, and a third-party service processes it to produce the training voice. The core exercises play audio and do not analyse the patient's speech. Evidence: Appendix - Australia, 3. How we collect your Personal Information.
  5. Applies to My Voices recordings, which are kept on the developer's servers.
  6. Applies only to My Voices recordings. The general privacy policy separately allows de-identified usage data to be used to improve the Platform and for research.
  7. This processor list appears in the privacy policy's Australia appendix. That appendix also names ElevenLabs (London) and Microsoft, Google, Meta, HubSpot and Stripe (USA) as overseas service providers. Evidence: Appendix - Australia, 5. Who we disclose Personal Information to.
  8. Only for the optional My Voices feature. The invited contact's recording is uploaded and processed on the developer's servers.
  9. Evidence: 11. Modification and Termination.
  10. This is a request-based disclosure right for California residents, made by contacting Neurotone. No self-service export is documented. The Australia appendix separately provides an access request right. Evidence: 16. California Residents.
  11. Only in the My Voices flow. The invited person records their own voice and must accept the Terms & Conditions before submitting it.
  12. Microphone input is used only when an invited family member or friend records a My Voices sample. Training exercises take answers by tap or click, not by voice.
  13. A hearing-care professional provisions the account and oversees progress.
