Terms of Service
Effective August 3, 2026 · Last updated August 29, 2026
These terms explain what Vocal Director offers and the basic rules for using it. We've kept them short and readable. By using the service, you agree to the terms below.
*
No medical diagnosis. Vocal Director offers AI vocal coaching and acoustic guidance for singing practice. It does not provide medical diagnosis and makes no clinical guarantee. Its outputs are educational guidance, not treatment.
02
User responsibility
You are responsible for the recordings you provide and for using the service in a way that respects your own vocal health. Rest if you feel strain, and consult a qualified professional for health concerns.
03
No medical diagnosis / no clinical guarantee
Vocal Director is not a medical device. Acoustic metrics are coaching-oriented estimates, not a medical diagnosis, and we make no clinical guarantee of any vocal outcome. Do not use the service as a substitute for professional medical or clinical advice.
04
AI coaching outputs
Reports, explanations, and recommendations are educational guidance generated by automated analysis. They may contain errors and should be used as practice suggestions, not definitive assessments.
05
Subscription, trial & payment
When a paid subscription is available in the Android app, Google Play shows the current price, billing period, and any trial or introductory offer before purchase. Subscriptions renew automatically unless cancelled through Google Play. Cancelling stops future renewal; paid access normally continues until the end of the current paid period unless Google Play indicates otherwise.
06
Refund policy
Subscription payments and eligible refund requests are handled through Google Play under its policies and the consumer-protection rules that apply in the user's region. A refund or revocation may end paid access before the previously displayed expiry time.
07
Acceptable use
Use the service lawfully. Do not upload content you have no right to use, attempt to disrupt the service, or misuse it in ways that harm others.
08
Intellectual property
Vocal Director and its content remain the property of their owners. You keep rights to your own recordings; you grant us permission to process them to provide the service.
09
Limitation of liability
To the extent permitted by law, Vocal Director is provided "as is" and we are not liable for indirect or incidental damages arising from use of the service.
10
Changes to terms
We may update these terms as the product evolves. Meaningful changes will be reflected here with an updated date.
