RAPPER Get it on iPhone

Terms of Use

Effective date: October 8, 2026

1. About Rapper & acceptance

Rapper is an AI-powered rap studio, free to use with an optional paid Premium subscription, available as a mobile app with a companion website at rapper.studio (together, the "Service"). Rapper shares its accounts and its Premium with Boppy, our other music app.

The Service is operated by GT Solutions, Budowlanych 1A, 62-081 Baranowo, Poland, EU VAT ID PL7792155376 ("we", "us").

These Terms of Use are a binding agreement between you and us. By creating an account, generating content, or otherwise using the Service, you agree to these Terms. If you do not agree, do not use the Service.

2. Eligibility & age

You must be at least 13 years old to use Rapper. If you are under 18, you must have the consent of a parent or guardian, who is responsible for your use of the Service, including any purchase. The Service is intended for a general teen-and-adult audience and is not a "Made for Kids" service.

3. Accounts

You can use Rapper with an anonymous account (limited free tracks) or sign in with Apple or Google. An anonymous account may be upgraded to a registered one, keeping your library. Each account is separate: songs, library and Premium do not move between accounts. If you buy Premium, keep using the account you bought it with — signing in another way creates a different account. You are responsible for the activity under your account and for keeping your credentials secure. You may not create accounts to evade a block, suspension, or content removal.

4. Use of the Service

4.1 Permitted use

You may use Rapper for personal, creative, and commercial purposes, subject to these Terms and applicable law.

4.2 Prohibited use

You agree not to use Rapper to:

5. User-generated content & zero tolerance

Rapper lets you create and share AI-generated tracks, lyrics, and artwork. We have zero tolerance for objectionable content and for abusive behaviour toward others. Content that is hateful, harassing, sexually explicit, violent, that sexually exploits or endangers minors, that infringes intellectual property, or that impersonates another person is strictly prohibited and will be removed.

Shared tracks can be reported. We review reported content and remove what violates these Terms; content that reaches our report threshold is automatically hidden pending review, and we act on objectionable-content reports — within 24 hours of a report where reasonably possible. We may remove any content and suspend or terminate the account of any user who posts objectionable content or behaves abusively, at our sole discretion and without prior notice.

6. Your content and inputs

6.1 Your responsibility

You are solely responsible for the content you provide to Rapper, including descriptions, lyrics, Rhyme Book pages, dictated recordings, and generation settings. We do not pre-screen or verify whether your inputs infringe on any third-party rights. You represent and warrant that you have the right to submit your content and that it does not violate any law or the rights of any third party.

6.2 Licence to us

By submitting content to Rapper, you grant us a non-exclusive, worldwide, royalty-free licence to store, process, transmit, and — when you choose to share content — display it, solely to operate the Service and deliver your output. We do not claim ownership of your inputs.

6.3 Content removal

You may remove your content yourself by deleting it or your account, or request removal by contacting us. We will make reasonable efforts to delete your content from our systems in a timely manner.

7. Sharing & moderation

When you share a track, it becomes accessible via a public link. Anyone with the link can listen to and view it. We may hide or remove any shared content that is reported or that violates these Terms, at our sole discretion and without notice.

8. Intellectual property and AI-generated content

8.1 Ownership of outputs

Rapper does not claim ownership over the audio, lyrics, or other content generated by the AI models through your use of the Service.

8.2 No copyright guarantee

The copyright status of AI-generated content is an evolving area of law and varies by jurisdiction. We make no representations or guarantees that AI-generated outputs are eligible for copyright protection, are free from third-party rights, or can be exclusively owned by you. You use AI-generated content at your own risk.

8.3 Third-party models

Music generation and lyric composition are powered by third-party AI models accessed through deAPI and OpenRouter. These services have their own terms that may affect your rights to the generated content. You are responsible for reviewing and complying with those terms.

8.4 Rapper brand and code

The Rapper name, logo, branding, and source code are our intellectual property. All rights reserved.

8.5 AI-generated content and labelling

All songs, vocals, lyrics and covers created with Rapper are generated by AI. Since 7 October 2026, MP3 files exported from Rapper carry the metadata tag "AI Generated = Yes". Do not remove this mark, and do not present AI-generated content as made by a person in a way that misleads others. When you publish a song elsewhere, follow that platform's rules, including any rules on labelling AI-generated content.

9. Rapper Premium & ads

Rapper Premium is an optional paid subscription, available in the app where your app store offers it. You can keep using Rapper for free without it.

9.1 Buying and price

You buy Premium through the Apple App Store or Google Play with your store account. The store shows the price, currency and taxes before you confirm; they may differ by country.

9.2 Automatic renewal

Premium is billed monthly and renews automatically at the then-current price until you cancel. The store charges your account within 24 hours before the end of each period.

9.3 Cancelling

Cancel at any time in your App Store or Google Play subscription settings, at least 24 hours before the end of the current period to avoid the next charge. Premium stays active until the end of the period you paid for. Deleting the app or your account does not cancel the subscription (Section 13).

9.4 Refunds

Apple and Google process all payments, so refund requests go to them under their policies; we cannot refund store purchases ourselves. If a payment is refunded or reversed, Premium ends.

9.5 What Premium includes

The features shown in the app when you buy. Currently: no ads; a song allowance per billing period (currently 200 songs); and other features marked Premium in the app. The allowance renews each period, unused songs do not carry over, and a failed generation does not count.

9.6 No free trial

Premium currently has no free trial. Any promotion is described in the app and in the store before you buy.

9.7 One Premium, two apps

Premium belongs to your account and works in both Rapper and Boppy, which use the same accounts; Premium bought in Boppy works in Rapper, and Premium bought in Rapper works in Boppy. Subscribing in both apps creates two separate subscriptions, each billed separately, and the song allowance does not add up.

9.8 Changes

We may change Premium's features or price as described in Section 14. Price changes are applied by the store, which tells you in advance and, where required, asks for your consent. If a change noticeably reduces what Premium includes, we tell you in the app in advance where we can. You can then cancel in the store and ask the store for a refund of the rest of the period under its policy.

9.9 EU right of withdrawal

If you are a consumer in the EU, you may have a right to withdraw within 14 days of buying. Premium starts as soon as you buy it, at your request; if you withdraw, the store may deduct the part already provided. Withdrawal and refund requests go through Apple or Google.

9.10 Ads

Free use of the app is supported by ads from Google AdMob; Premium removes them. In Rapper, watching an ad is your choice: when an ad is offered you can tap Watch ad or Not now. Ads may be personalised or non-personalised depending on your tracking choice — on iOS you can allow or decline tracking via Apple's App Tracking Transparency prompt and change it anytime in iOS Settings; see our Privacy Policy. Ad rewards have no cash value and cannot be transferred.

10. No warranties and limitation of liability

10.1 No warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR FREE FROM VIRUSES OR OTHER HARMFUL COMPONENTS.

10.2 Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, RAPPER AND ITS OPERATORS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF PROFITS, DATA, USE, OR GOODWILL, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICE. THIS INCLUDES, WITHOUT LIMITATION, DAMAGES ARISING FROM: (A) SERVICE DOWNTIME, INTERRUPTIONS, OR DISCONTINUATION; (B) ERRORS, BUGS, OR INACCURACIES IN GENERATED CONTENT; (C) ANY LOSS OR DAMAGE TO YOUR DATA OR CONTENT; (D) INTELLECTUAL PROPERTY CLAIMS BY THIRD PARTIES RELATED TO AI-GENERATED OUTPUTS. OUR TOTAL LIABILITY FOR ALL CLAIMS ABOUT THE SERVICE IS LIMITED TO THE AMOUNT YOU PAID FOR THE SERVICE IN THE 12 MONTHS BEFORE THE CLAIM, OR EUR 50 IF THAT IS HIGHER.

These limits do not apply where the law does not allow them — including liability for intent or gross negligence, and for death or personal injury caused by negligence — and they do not affect your statutory rights as a consumer. Nothing in these Terms limits or excludes any rights you have under mandatory consumer-protection law that cannot be limited or excluded.

11. Indemnification

You agree to indemnify, defend, and hold harmless Rapper and its operators from and against any and all claims, liabilities, damages, losses, costs, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) your use of the Service; (b) your content or inputs; (c) your violation of these Terms; or (d) your violation of any rights of a third party.

12. Account suspension & termination

We may suspend, block, or terminate your account and access to the Service at any time, with or without notice, if you violate these Terms, post objectionable content, abuse other users, attempt to evade a block or removal, or if we are required to do so by law. On termination we may delete or disable your account, library, and shared content. If we close your account while Premium is active, cancel the subscription in the store so it stops renewing. If we close it without a breach on your side, we will help you ask the store for a refund of the unused period. Provisions that by their nature should survive (intellectual property, disclaimers, limitation of liability, indemnification, and governing law) survive termination. You may stop using the Service and delete your account at any time, as described in Section 13.

13. Account deletion

You can delete your account at any time from the app's Settings screen. Deletion is permanent and removes your account, your full library of generated tracks, and any public shares you created. Deleting your account or the app does not cancel Premium — cancel it in your App Store or Google Play subscription settings. See our account deletion page and Privacy Policy for details on what data is removed or retained.

14. Modifications and discontinuation

We reserve the right to modify, suspend, or discontinue the Service (or any part of it) at any time, with or without notice. We may also update these Terms at any time. Continued use of the Service after changes constitutes acceptance of the updated Terms. We are not liable to you or any third party for any modification, suspension, or discontinuation of the Service.

15. Third-party services

Rapper relies on third-party services including deAPI (music generation and speech-to-text), OpenRouter (lyric composition), Sign in with Apple and Google (authentication), the Apple App Store and Google Play (Premium purchases), and Google AdMob (advertising in the free app). We are not responsible for the availability, accuracy, or practices of these services; their terms and privacy policies apply. See our Privacy Policy.

16. Governing law & operator

The Service is operated by GT Solutions, Budowlanych 1A, 62-081 Baranowo, Poland, EU VAT ID PL7792155376. These Terms are governed by Polish law. If you are a consumer, you keep the mandatory protection of the law of your country of residence and may bring claims before the courts there.

17. Apple App Store & Google Play

These Terms are between you and the operator of Rapper only, not Apple, and Apple is not responsible for the app or its content. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. Your use of the app must also comply with the Apple Media Services Terms and Conditions.

If you got the app from Google Play, the Google Play Terms of Service and policies also apply, including to purchases and refunds.
