Terms of Service

1. The Service

sentivoice accepts audio files, video files, or YouTube links you provide, processes them using automated audio/video analysis and third-party AI models, and returns a performance report (scores, timestamps, and coaching advice).

The service is provided for personal, educational, and coaching purposes. Reports are generated automatically and may contain inaccuracies - they are not a substitute for professional vocal coaching or medical advice.

2. Your Content and Rights

You must own the content you upload, or have the legal right to submit it for analysis (for example, a recording of your own performance, or a performance you have permission to analyze).

When you submit a YouTube link, you represent that your use of that content through this service - including downloading, processing, and AI analysis - is authorized by the rights holder or falls under an applicable exception (such as fair use) in your jurisdiction. You are solely responsible for that determination.

You must not use the service to process content you know or have reason to believe infringes a third party's copyright, privacy rights, or other rights.

We reserve the right to remove content or suspend accounts we believe are being used to process infringing material, without prior notice.

To help enforce this, we run an automated check comparing your recording's backing track against a database of known commercial music (see Section 3). If a likely match is found, we do not complete the analysis - the submission is stopped and deleted immediately, without retaining any trace of it. This check is automated and best-effort: it will not catch every instance of copyrighted material, and passing it does not by itself establish that you hold the necessary rights.

3. Third-Party Processing

To generate your report, your audio/video (or short clips/derivatives of it) is sent to third-party AI providers, including Google's Gemini API, for analysis. That processing is subject to the third party's own terms and privacy practices in addition to ours.

YouTube links are retrieved using publicly available extraction tools. You are responsible for ensuring your use of any YouTube content complies with YouTube's Terms of Service.

To screen backing tracks for commercial/copyrighted music (see Section 2), an audio fingerprint derived from your recording, not the audio file itself, is sent to AudD, a third-party audio-identification service, for lookup.

We use Mixpanel, a third-party analytics provider, to understand how the service is used. If you are signed in, this usage data is associated with your account email.

4. Data Retention

Uploaded files, generated audio (e.g. isolated vocal stems), and analysis results are automatically and permanently deleted approximately 24 hours after a job is created. After that point they are not recoverable by us or by you.

If you create an account, we retain your account email and a list of your past job metadata until you delete your account or request deletion (see Section 6).

For every successfully completed analysis, we automatically keep a lightweight, permanent record of your scores and a melody fingerprint (not the underlying audio) so a future upload of the same song can be recognized and compared. If you use the Vocal Coach feature to confirm two recordings are versions of the same song, this record becomes part of that song's version history. You can delete this history at any time by deleting the song or your account.

5. Acceptable Use

You agree not to: (a) use the service to process content you do not have rights to; (b) attempt to disrupt, reverse-engineer, or overload the service; (c) use the service for any unlawful purpose.

6. Your Account and Data Rights

If you sign in, you may request deletion of your account and all associated stored data at any time by contacting us at the address below. We will process such requests within a reasonable time.

7. Disclaimer of Warranties

The service is provided "as is" without warranties of any kind. We do not guarantee the accuracy of AI-generated scores, timestamps, or advice. Automated pitch/key/timing detection and AI-generated coaching text may be wrong.

8. Limitation of Liability

To the maximum extent permitted by law, sentivoice and its operators are not liable for any indirect, incidental, or consequential damages arising from your use of the service, including damages related to third-party copyright claims arising from content you submitted.

9. Changes

We may update these Terms from time to time. Continued use of the service after changes take effect constitutes acceptance of the updated Terms.
