Welcome to SonnaLabs. These Terms of Service ("Terms") govern your access to and use of the SonnaLabs mobile application and website at sonnalabs.app (collectively, the "Service"). By creating an account or using the Service, you agree to be bound by these Terms.
By accessing or using SonnaLabs — whether through the Android mobile application or the web platform — you confirm that you have read, understood, and agreed to these Terms in full. If you do not agree, you may not use the Service.
SonnaLabs is an AI-powered creative platform that enables users to generate audio, images, videos, and music using state-of-the-art AI models. The Service is accessible via:
Available features include:
Features and model availability may vary between platforms. SonnaLabs reserves the right to modify, suspend, or discontinue any part of the Service at any time.
You must be at least 13 years of age to use the Service. By registering, you confirm you meet this requirement. If you are under the age of majority in your jurisdiction, you may only use the Service with the consent and involvement of a parent or legal guardian.
SonnaLabs reserves the right to verify eligibility and to refuse or terminate accounts at its discretion.
Credits are the unit of consumption used within SonnaLabs. Credits are not a currency, have no monetary value outside the Service, and are non-transferable. All feature usage — text to speech, image, video, and music generation — deducts credits from your balance.
Credit spend order (automatic): Subscription credits are spent first, then free credits, then PAYG credits. This order ensures your monthly free allowance is utilized before consuming non-expiring purchased credits.
The Free plan provides 10,000 credits per month, automatically reset at the start of each monthly cycle. Unused free credits from the previous cycle are not carried over — they are replaced by the new monthly allocation.
Free plan access is limited to Google Cloud TTS voices and HeyGen Voice Turbo. Image, video, music generation, ElevenLabs TTS, and HeyGen Voice require a paid plan or PAYG credits.
On the Android application, the Free plan shows ads from Google AdMob before a generated text-to-speech result. Pro, Max and PAYG users see no ads. See the Privacy Policy for how advertising data is handled.
Paid Pro and Max plans are available via two channels, each with its own billing model:
Android (Google Play) — auto-renewing subscription:
Web (sonnalabs.app) — one-time purchase, no subscription:
Web purchases include a +10,000 bonus credit allocation compared to Android, because Midtrans platform fees are lower than Google Play's. The saving is passed on to you as extra credits at the same price.
Credit allocation — Web (Midtrans, one-time purchase):
Credit allocation — Android (Google Play, monthly subscription):
On Android, these credits are granted each month while the subscription remains active. On the web, they are granted once per purchase and are valid for 30 days from the purchase date.
On Android, subscription credits roll over — unused credits are added to your balance when the next cycle's allocation is granted while the subscription stays active. On the web, Pro and Max credits are valid for 30 days from purchase; buying again adds more credits and extends the validity to the later expiry date. In both cases this differs from the Free plan, which resets rather than accumulates.
When an Android subscription lapses, or when web Pro/Max credits reach their 30-day expiry, the remaining plan credits are set to zero and the account reverts to the Free plan. PAYG credits are never affected.
Cross-platform notice: Credits are tied to your account, not to a specific platform, and purchases stack. You may buy on Android (Google Play) and on the web (Midtrans), and repeat-purchase on either channel — each purchase adds its credits to your balance. Your plan's expiry date always reflects the later of your current and newly purchased expiry, so you never lose access you have already paid for. Keep in mind that an Android purchase is an auto-renewing subscription managed through Google Play, while a web purchase is a one-time payment that does not auto-renew; you can manage or cancel your Android subscription at any time in the Play Store.
PAYG credit packs are available for one-time purchase through the web platform. Packs are fixed presets — custom top-up amounts are not supported. To accumulate more credits, you may purchase multiple packs; credits stack and are valid for 1 year (365 days).
All PAYG purchases are shown in US Dollars (USD). Checkout is charged in Indonesian Rupiah (IDR), and your card issuer or bank converts the amount automatically.
PAYG credits are valid for 1 year (365 days) and are retained even if your monthly plan lapses or expires. PAYG credits are spent after plan credits in each transaction.
If a generation request is accepted by the system but fails before producing a result (due to an AI provider error, timeout, or system fault), any credits deducted for that request are automatically returned to your account. This refund restores credits to the exact bucket from which they were deducted (subscription, PAYG, or free). You do not need to contact support for generation failure refunds.
Credits have no cash value. SonnaLabs does not offer monetary refunds for unused credits, except as expressly stated in the Refund Policy. Credits cannot be transferred between accounts, exchanged for money, or redeemed outside the Service.
SonnaLabs' generation capabilities are powered by ElevenLabs, HeyGen, Google (Cloud TTS), Suno, OpenAI, and other AI model providers. By using the Service, you agree to comply with SonnaLabs' rules below and the usage policies of each upstream provider. Where a provider's policy is stricter than SonnaLabs', the stricter rule applies.
You agree not to use the Service for any of the following:
Violations of this category will result in immediate, permanent account termination and reporting to relevant child protection authorities as required by applicable law.
Important: SonnaLabs does not provide voice cloning tools or features. SonnaLabs is a text-to-speech platform that gives users access to voices published on the ElevenLabs Voice Library by independent voice creators, to standard voices from Google Cloud TTS, and to public voices from HeyGen. No part of SonnaLabs allows a user to clone, replicate, or synthesize a new voice from recordings.
The following uses of SonnaLabs' text-to-speech output are strictly prohibited:
ElevenLabs independently operates a content detection and enforcement system on their platform that traces generated audio back to the originating account and enforces their own Prohibited Use Policy. This enforcement is handled entirely by ElevenLabs — SonnaLabs accesses ElevenLabs' service as an API customer and is bound by their terms of use, including their content enforcement mechanisms.
Exception: Clearly fictional contexts (novels, films, games, journalism) are generally permitted, provided the content would not be reasonably mistaken for factual claims about real persons.
Violation of any of the above may result in immediate account suspension, permanent termination, credit forfeiture, and referral to law enforcement where appropriate.
Provider-level safety (automatic, before output reaches you):
Every generation request passes through safety filters operated by the upstream AI provider before any output is returned. These operate independently of SonnaLabs:
When a provider rejects a request due to content policy, SonnaLabs receives an error signal and automatically refunds the credits deducted for that request. This happens transparently — you do not need to contact support.
SonnaLabs-level handling:
SonnaLabs' backend has a dedicated SensitiveContentError classification. When a provider returns a content-policy rejection, SonnaLabs:
FAILED_PROVIDER_REJECTED (content policy rejection) — distinct from a technical failureWhat this means for you:
If your request is rejected due to content policy:
What SonnaLabs does not do:
SonnaLabs does not maintain a custom prompt-screening layer that pre-filters your inputs before sending them to providers. The safety enforcement happens at the provider level. SonnaLabs' role is to correctly handle the provider's rejection signal, refund credits, and communicate the outcome to you.
You acknowledge and agree that:
SonnaLabs provides AI generation tools as a technology platform. SonnaLabs is not the author, publisher, or distributor of the content you generate. You are solely responsible for all content you create using the Service.
The AI models available through SonnaLabs process your inputs and return outputs. At no point does SonnaLabs review, approve, or endorse the specific content you choose to generate, distribute, or apply. By submitting any prompt, text, image, audio, or other input to the Service, you:
SonnaLabs operates as a platform intermediary. Its role is to provide the technical infrastructure that routes your requests to AI model providers and returns the results to you. SonnaLabs does not:
This structure means SonnaLabs functions similarly to a hosting provider or communication platform — SonnaLabs provides the tools; you decide how to use them.
If you use the Service to generate content that:
you bear sole legal and financial responsibility for any resulting claim, loss, damage, fine, or penalty. SonnaLabs assumes no liability whatsoever for the content you generate or how you use it.
SonnaLabs is under no obligation to proactively monitor, scan, or filter content that passes through the Service. However, SonnaLabs reserves the right to:
Reporting suspected violations: support@sonnalabs.app.
By using the Service, you represent and warrant — on a continuing basis for every use — that:
If any of these representations are false, you are in material breach of these Terms and SonnaLabs may immediately terminate your account.
All platform elements — including but not limited to the SonnaLabs brand, logo, interface design, source code, and documentation — are the intellectual property of SonnaLabs' developer. You may not copy, reproduce, modify, distribute, or create derivative works from any SonnaLabs platform materials without prior written consent.
AI model names (ElevenLabs, HeyGen, Gemini, Suno, etc.) are trademarks of their respective owners. SonnaLabs' use of these models does not imply any endorsement or partnership beyond what their standard API access terms allow.
You retain all rights to the text, prompts, lyrics, and other content that you personally write and submit to the Service. If you write your own lyrics in a music generation request, those lyrics remain yours.
The legal status of purely AI-generated content is an evolving area of law. Based on current guidance from copyright authorities:
SonnaLabs makes no guarantee that the copyright office of any country will recognize ownership claims over AI-generated music, audio, images, or video produced through the Service.
Music generation in SonnaLabs is powered by Suno. The commercial rights framework is governed by Suno's terms:
Users with paid access (Pro, Max, or PAYG credits):
Music generation requires paid access:
Music generation (via Suno Model) is only available to users with an active Pro or Max subscription, or a positive PAYG credit balance. Free plan users do not have access to music generation.
Cover songs (songs that attempt to replicate existing copyrighted melodies or compositions):
Remix / Extend within SonnaLabs:
The legal framework around AI-generated music is still developing globally. As with all AI model providers, the underlying models used by SonnaLabs' music generation feature may be subject to evolving legal and regulatory developments that are outside SonnaLabs' control.
Future legal or regulatory changes may affect what AI models can generate, the commercial rights available for AI-generated music, or the ability to register such music with copyright offices. SonnaLabs makes no representations about the legal environment governing its AI model providers.
You use SonnaLabs' music generation features with awareness of this evolving context. SonnaLabs is not liable for any changes to the rights framework resulting from developments involving third-party AI model providers.
Free plan: Free plan users only have access to Google Cloud TTS (Neural2 / WaveNet voices) and HeyGen Voice Turbo. Music generation, image generation, video generation, ElevenLabs TTS, and HeyGen Voice all require an active Pro or Max subscription, or a positive PAYG credit balance. There are no free-tier commercial rights for these features because they are not accessible on the free plan.
Google Cloud TTS terms additionally prohibit using generated audio to train competing speech synthesis models.
By using the Service, you acknowledge that SonnaLabs technically processes your inputs (sending them to AI providers) and temporarily stores your outputs (to deliver them back to you and maintain your generation history). This is purely operational — SonnaLabs does not use your content for any other purpose, does not claim ownership of your outputs, and does not share your content with third parties beyond what is necessary to route requests to the AI model providers listed in the Third-Party Services section.
You represent and warrant that you have all necessary rights to submit any content you provide, and that doing so does not infringe the rights of any third party.
Paying users (active Pro/Max subscription or positive PAYG balance) may create API keys to access SonnaLabs' generation features programmatically via the Developer API.
SonnaLabs integrates with the following third-party providers to deliver the Service. Your use of the Service implies your acceptance that certain data (as described in SonnaLabs' Privacy Policy) is transmitted to these providers:
SonnaLabs is not responsible for the uptime, quality, or policies of any third-party service. Changes to third-party services may affect feature availability without advance notice.
Your use of the Service is governed by SonnaLabs' Privacy Policy, which is incorporated into these Terms by reference. Please read it carefully before using the Service.
You may delete your account at any time through:
Deletion is scheduled for 14 days after you request it, and you are signed out of all devices immediately. Signing in again within those 14 days cancels the deletion; after that, your account, projects, generated files, and personal data are permanently deleted and this cannot be undone. Records of purchases and credit transactions are retained as required by applicable law for tax, accounting, legal, and fraud-prevention purposes and are no longer linked to a usable account. Unused credits (including PAYG credits) are forfeited upon account deletion and will not be refunded in monetary form.
SonnaLabs may suspend or permanently terminate your account, at its sole discretion, in response to:
In cases of suspension for serious policy violations (including illegal content involving minors, fraud, or other illegal activity), any remaining credits will be forfeited without refund.
The Service is provided "as is" and "as available" without warranties of any kind, express or implied. SonnaLabs does not warrant that:
No warranty on content output: SonnaLabs expressly disclaims any and all liability for the substance, accuracy, legality, or appropriateness of AI-generated audio, images, videos, or music produced through the Service. The Service provides a tool; it does not guarantee the nature of what that tool produces in any given instance.
To the extent permitted by applicable law, all implied warranties, including merchantability and fitness for a particular purpose, are disclaimed.
To the maximum extent permitted by applicable law, SonnaLabs and its developer shall not be liable for:
SonnaLabs is not a content publisher. SonnaLabs does not review, endorse, or control the content of individual user generations. The platform is a conduit; liability for content lies with the user who initiated the generation and chose to use the output.
Where liability cannot be excluded by law, SonnaLabs' total liability is limited to the amount you paid to SonnaLabs in the 30 days preceding the event giving rise to the claim.
You agree to indemnify, defend, and hold harmless SonnaLabs and its developer from and against any and all claims, liabilities, damages, judgments, losses, costs, and expenses arising out of or related to:
This obligation to indemnify survives termination of your account and these Terms.
SonnaLabs reserves the right to update these Terms at any time. When material changes are made, the "Last updated" date at the top of this page will be updated. For significant changes, SonnaLabs will make reasonable efforts to notify you via in-app notification or email. Continued use of the Service after changes are published constitutes acceptance of the revised Terms.
These Terms are governed by and construed in accordance with the laws of Indonesia. Any disputes arising from these Terms or your use of the Service shall be subject to the jurisdiction of the courts of Indonesia.
