Terms of Service

1. The Service

SentiVoice ("we", "us", "the Service") is operated by Anatolii Hlushko, an individual trader (sole proprietorship) established in United States, at 1317 China Dr, Morrisville, NC 27560. As a sole proprietorship there is no commercial-register entry or company registration number; Anatolii Hlushko personally is the party you contract with.

SentiVoice accepts audio or video files 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 also includes Vocal Coach, which sets targeted exercises that you perform into your device's microphone and which are scored automatically; a Vocal Range Test, which uses your microphone to estimate your vocal range and voice type; optional skill certificates (Section 5); and published educational articles.

Recordings submitted for analysis are limited to 10 minutes. File size limits are shown on the upload page.

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, and they are not medical advice. If you experience pain, persistent hoarseness, or other symptoms, consult a qualified medical professional.

2. Eligibility

You must be at least 13 years old to use the Service. We do not knowingly collect personal data from anyone under 13, and if we learn that we have, we will delete it.

If you are between 13 and the age of majority where you live, you may use the Service only with the involvement and consent of a parent or guardian, who is responsible for your use of the Service.

3. 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).

Recordings you make through Vocal Coach or the Vocal Range Test are your content as well, and the same rights and responsibilities apply to them.

To provide the analysis you ask for, you grant us a limited, non-exclusive, worldwide, royalty-free licence to store, copy, transmit, and process the content you submit, and to create derived audio from it such as isolated vocal stems, solely in order to produce your report and the features you requested. That licence extends to the third-party processors named in Section 6 and to no one else, ends when the content is deleted on the schedule in Section 7, and does not permit us to publish or share your content or to use it to train our own models. You keep ownership of everything you submit.

Voice data note: where your recording is used only to produce coaching feedback (pitch, timing, tone) and not to identify you as an individual, we do not treat it as biometric identification data.

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.

You agree to indemnify and hold us harmless from any claim, loss, or expense (including reasonable legal fees) arising from content you submit that infringes a third party's rights, or from your breach of this Section.

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

If you believe material processed through this Service infringes your rights, our Copyright and Takedown Policy sets out how to send a notice, how we respond, how to file a counter-notice, and when we terminate accounts for repeat infringement.

To help enforce this, we run an automated check comparing your recording's backing track against a database of known commercial music (see Section 6). 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.

4. Plans, Credits and Payment

The Service has a free tier and paid subscription plans. Current plans, prices, and what each includes are shown on the Prices page.

Payments are processed by Stripe. We do not receive or store your full card details.

Usage is measured in tokens. Each plan includes a monthly token allowance, and each successfully completed action consumes tokens: a standard analysis costs 5 tokens, a deep (full-song) analysis costs 20, and issuing a certificate costs 100. The free tier receives 10 tokens per cycle, which is below the cost of a single deep analysis — deep analysis is not available on the free tier.

If a submission fails for a reason within our control (system error, processing failure) rather than because you cancelled it or it was blocked by the copyright check in Section 3, the tokens for that submission are not charged, or are refunded automatically.

Your token allowance resets on a rolling 30-day cycle that starts when your allowance last reset. This cycle is tracked separately from Stripe's billing dates, so the day your allowance resets will not necessarily be the day you are charged. Unused allowance does not carry over.

You may also buy credits as a one-off top-up. Your monthly allowance is always spent first, and credits are drawn on only once it is exhausted. Credits are not a subscription and are not cleared by the monthly reset.

Subscriptions renew automatically at the then-current price until you cancel. We will email you before each renewal that involves a price change, and, where required by local law, before a standard renewal as well. You can cancel at any time from Settings — cancellation is self-service and does not require contacting support. Cancellation takes effect at the end of the period you have already paid for, and you keep access until then. We do not refund unused time in a period that has already started, except where required by law.

Upgrading to a higher plan takes effect immediately, and we will charge a pro-rated amount for the remainder of the current billing period. Downgrading takes effect at the end of your current billing period, so you keep your current plan and allowance until then.

If a payment fails or a subscription lapses, your account reverts to the free tier. We will attempt to notify you before this happens.

Prices may change. We will give notice before a change affects a renewal, and you may cancel before it takes effect.

If you are a consumer in the EU or UK, you have a statutory right to withdraw from a purchase within 14 days. Where you ask us to begin providing paid features immediately, that right ends once the Service has been fully performed, or once you have used the paid features, whichever these rules require in your jurisdiction. Nothing in these Terms limits statutory rights that cannot be waived.

5. Certificates

A certificate is an optional, paid record of your assessed skill level at the moment it is issued. Issuing one costs 100 tokens.

Each certificate carries a unique code, and anyone holding that code can check it on our public verification page. That page shows the name you chose to put on the certificate, the assessed level, the category scores, and the issue date. It does not show your email address.

Certificates are immutable — they are never edited after being issued, so a certificate remains verifiable exactly as issued. If your assessed level changes, you issue a new certificate rather than updating an existing one.

A certificate records an automated assessment produced by this Service. It is not an accredited qualification, and it is not issued or recognized by any examination board, conservatoire, or educational institution.

Deleting your account deletes your certificates, after which their codes will no longer verify.

6. 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.

To screen backing tracks for commercial/copyrighted music (see Section 3), a short excerpt of about 20 seconds — taken from the separated backing track of your recording, not from your voice and not the whole file — is sent as audio to AudD, a third-party audio-identification service, which matches it against its catalogue of commercial recordings.

Payments and subscription management are handled by Stripe, which processes your payment and billing details under its own terms and privacy policy.

We use Mixpanel, a third-party analytics provider, to understand how the Service is used. Analytics are collected from all visitors, including those who are not signed in. If you are signed in, this usage data is associated with your account email. Where prior consent is legally required (currently the EEA and the UK), we ask before any analytics are collected, and you can change your choice at any time in Settings.

The full list of processors we use, and where they are located, is set out in our Privacy Policy at sentivoice.com/privacy.

7. 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. When local playback is enabled for an analysis, the uploaded recording is instead deleted as soon as the analysis completes and is kept only in the browser on the device it was uploaded from; if that browser cannot play the recording's format, a compressed audio copy is kept for at most 60 minutes so it can be transferred to it. The isolated vocal, a silent reduced-size copy of a video, and the results of such an analysis are deleted approximately 7 days after the job is created. After that point they are not recoverable by us or by you.

Recordings you make through Vocal Coach or the Vocal Range Test are deleted on the same approximately 24-hour schedule. The scores derived from them are kept as part of your practice history.

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 9).

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.

Certificates you have issued are kept until you delete your account, so that their codes continue to verify.

When an account is deleted, we keep one pseudonymized marker for up to 30 days: a keyed hash of the account email together with the free-tier usage counter at the time of deletion. It exists solely so that deleting and re-creating an account cannot be used to reset the free allowance, it contains no readable email address and no other account data, and it is deleted automatically at the end of that period.

8. 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; (d) attempt to circumvent the copyright-screening check described in Section 3; (e) resell, sublicense, or provide access to the Service to third parties without our written permission.

We may suspend or terminate your account for violating this Section, with notice where practicable.

9. Your Account and Data Rights

If you sign in, you can delete your account and all associated stored data yourself at any time from Settings. Before you confirm, the page lists what will be destroyed. If you have an active paid subscription, cancel it first — deletion is blocked while a subscription can still bill, so that you are never left paying for an account that no longer exists.

You can also ask us to delete your account and all associated stored data by writing to support@sentivoice.com. We will process such requests within a reasonable time, and in any case within any deadline required by applicable law (for example, one month under the GDPR).

Deleting your account removes your analyses and their metadata, your Vocal Coach problems, exercises, attempts and their recordings, your tracked songs and their version history, and your certificates. The one exception is the pseudonymized free-allowance marker described in Section 7.

Depending on where you live, you may have additional rights over your personal data (access, correction, portability, objection) — see our Privacy Policy at sentivoice.com/privacy for how to exercise them.

10. Disclaimer of Warranties

The Service is provided “as is” without warranties of any kind, to the fullest extent permitted by law. 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.

If the law of your jurisdiction does not allow the exclusion of certain implied warranties, some of the exclusions in this Section may not apply to you.

11. 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.

Our total liability to you for any claim arising from these Terms or the Service is limited to the amount you paid us in the 12 months before the claim arose, or US$50, whichever is greater.

Nothing in this Section limits liability that cannot be limited under applicable law (for example, liability for death, personal injury, or fraud).

12. Governing Law and Disputes

These Terms are governed by the laws of the State of North Carolina, United States, without regard to its conflict-of-laws rules. The state and federal courts located in North Carolina have jurisdiction over any dispute arising from these Terms or the Service.

If you are a consumer, this does not deprive you of the protection of the mandatory consumer-protection rules of the country where you live, and it does not prevent you from bringing proceedings before the courts of that country where the law there gives you that right.

13. General

Severability. If any part of these Terms is found unenforceable, the rest remains in effect.

Entire agreement. These Terms, together with our Privacy Policy and Copyright and Takedown Policy, are the entire agreement between you and us regarding the Service.

Assignment. We may assign these Terms in connection with a merger, acquisition, or sale of assets. You may not assign your rights under these Terms without our consent.

Force majeure. We are not liable for delays or failures caused by events beyond our reasonable control.

14. Changes

We may update these Terms from time to time. For material changes, we will provide notice (for example, by email or an in-product notice) before the change takes effect. Continued use of the Service after changes take effect constitutes acceptance of the updated Terms.

15. Contact

Questions about these Terms can be sent to support@sentivoice.com, or by post to Anatolii Hlushko, 1317 China Dr, Morrisville, NC 27560, United States.
