Terms of Use

1. Acceptance

These Terms of Use ("Terms") form the agreement between Ra. Soft LTD ("we") and you, the person using the Cantavo app (com.cantavo.app). By downloading, installing or using the app you accept these Terms and the Privacy Policy. If you do not accept them, do not use the app and remove it from your device.

2. What the service is

Cantavo is a vocal practice app: it separates the vocal from the instruments in a recording, extracts the notes that were sung, and compares the pitch you sing into the microphone against those notes to give you feedback. It also offers an exercise workshop, recording and studio tools, transposition, tempo change and export.

Analysis runs partly on your device and partly on a cloud server (see Privacy Policy, section 6). Analysis results are statistical estimates; no guarantee of musical accuracy is given.

3. Age and capacity

You must be at least 13 years old (or older, where your country sets a higher age) and capable of entering into this agreement. If you are a minor, use the app only with the knowledge and permission of your parent or guardian; that permission extends to any paid subscription.

4. Accounts

The core features work without an account. If you create one, you are responsible for the accuracy of the details you provide and for keeping your credentials confidential. Activity through your account is treated as yours. Tell us if you suspect unauthorised access.

You can delete your account from the account panel inside the app at any time. Deleting an account does not by itself cancel an active subscription — cancellation happens in your App Store account settings (see section 7).

5. Copyright and content use

Accordingly:

1. You represent and warrant that you hold the necessary rights and permissions for every file you upload. Verifying ownership is not technically possible for us, so responsibility rests entirely with you.
2. The vocal separation feature may not be used to produce and distribute karaoke or instrumental versions of copyrighted works. The stems stay on your device and are for practice only.
3. You may export recordings of your own singing. If you want to publish such a recording together with a copyrighted backing track, obtaining the necessary licences from the rightsholders is your obligation.
4. Demo songs bundled with the app come with their own licences (stated inside the app); you must comply with those licence terms.
5. Where a rightsholder notifies us of an infringement, we reserve the right to suspend or close the relevant content or account.

6. Prohibited uses

• Uploading recordings you have no right to use, or producing and distributing derivatives of them.
• Recording or imitating another person's voice without their consent, or producing misleading content.
• Reverse engineering or decompiling the app, circumventing security measures, or placing automated or excessive load on our APIs.
• Attempting to bypass the free analysis credit system or subscription verification.
• Reselling, renting or offering the app to third parties as a service.
• Any use that breaches applicable law.

7. Subscription, renewal and cancellation

Cantavo Pro is sold as an auto-renewing subscription through the Apple App Store. Current plans and prices are shown on the subscription screen in the app and in the App Store.

• Payment is charged to your Apple ID account when you confirm the purchase.
• The subscription renews automatically unless you cancel at least 24 hours before the end of the current period, and is charged for the same period again.
• The renewal charge is taken within 24 hours before the period ends.
• You can manage and cancel your subscription under Settings → your Apple ID → Subscriptions. Cancellation takes effect at the end of the current period; you keep access for the remainder of it.
• Where an introductory or discounted price is offered, the subscription renews at the standard price once the introductory period ends. Introductory prices apply to eligible users and once only.
• Where a free trial is offered, the subscription becomes paid unless cancelled 24 hours before the trial ends; any unused portion of a free trial is forfeited when a subscription to the same content is purchased.

When a subscription ends, access to paid features stops. Practising with the bundled demo songs, the exercises and the recording tools remain available; your own songs analysed during the subscription period stay locked until the subscription is active again. Files on your device are not deleted.

8. Free analysis credits

Without a subscription you can analyse a limited number of your own songs (the exact count is shown in the app). This credit:

• is spent only on an analysis that completes successfully — a failed or cancelled analysis costs nothing,
• is not restored by deleting a song,
• is not charged a second time when you re-analyse the same song,
• is never spent on the demo songs bundled with the app.

9. Refunds and withdrawal

Because Apple handles the sale, refund requests go to Apple (reportaproblem.apple.com). Whether a refund is granted is governed by Apple's policies; we have no unilateral ability to issue one.

Under consumer law, the right of withdrawal for digital content and services may lapse once performance has begun with your consent. Mandatory consumer rights under the law of your country of residence are unaffected by this section.

10. Intellectual property

The app, its interface, design, source code, brand, logo and bundled content belong to Ra. Soft LTD or its licensors. Subject to these Terms, you are granted a non-transferable, non-exclusive, revocable licence to use the app for personal, non-commercial purposes on Apple-branded devices that you own or control. No other rights are transferred.

11. Your content

The files you upload, your recordings and the outputs derived from them belong to you. We claim no ownership over them. We are authorised to process them only to perform the analysis you requested and deliver the result to you, for as long as that operation requires. We do not use your content for marketing, do not disclose it to third parties and do not use it to train models.

12. Relationship with Apple

This agreement is between you and Ra. Soft LTD; Apple is not a party to it.

• We alone are responsible for maintenance and support of the app; Apple has no obligation to provide any.
• If the app fails to conform to any applicable warranty, you may notify Apple and Apple may refund the purchase price. To the maximum extent permitted by law, Apple has no other warranty obligation.
• We, not Apple, are responsible for addressing claims relating to the app, including product liability, regulatory compliance and consumer protection claims.
• We, not Apple, are responsible for the investigation and defence of any third-party claim that the app infringes intellectual property rights.
• Apple and its subsidiaries are third-party beneficiaries of these Terms and have the right to enforce them against you.
• By using the app you represent that you are not located in a country subject to a U.S. Government embargo and are not listed on any U.S. Government list of prohibited or restricted parties.

13. Availability and changes

We keep developing the app; features may change, be added, or be paused temporarily where technically necessary. The cloud analysis service may be unavailable for maintenance, provider outages or heavy load; in that case the app offers on-device analysis instead. No uninterrupted service is guaranteed.

14. Disclaimer of warranties

To the maximum extent permitted by law, the app is provided "as is". We do not warrant that it will run uninterrupted or error-free, that analysis results will be musically flawless, or that it will produce any particular training outcome. Mandatory consumer rights that cannot be limited by contract remain unaffected.

15. Limitation of liability

To the maximum extent permitted by law, we are not liable for indirect damages, loss of profit, loss of data, business interruption or failure to realise expected benefits. In any event our total liability is limited to the amount you paid us for the app in the twelve (12) months preceding the event giving rise to the claim.

This limitation does not apply in cases of wilful misconduct, gross negligence, death or personal injury, or where the law does not permit limitation.

16. Indemnity

You agree to indemnify us against third-party claims, damages we incur and reasonable legal costs arising from your use of the app in breach of these Terms, in particular sections 5 and 6.

17. Termination

You may end this agreement at any time by removing the app from your device; a paid subscription must additionally be cancelled through the App Store. We may suspend your access or terminate the agreement if you materially breach these Terms. Sections 10, 15, 16 and 18 survive termination.

18. Governing law

These Terms are governed by the laws of the Republic of Türkiye, and the courts and enforcement offices of Istanbul have jurisdiction. If you are a consumer, your right to apply to the consumer arbitration committees and consumer courts where you live, and the mandatory consumer protections of your country of residence, remain unaffected.

19. Changes to these Terms

We may update these Terms. The current text is always published at this address and the effective date in the header changes with it. For material changes we also notify you inside the app; continuing to use the app afterwards means you accept the new text.
