These Terms of Service (“Terms”) govern your use of the Antheo application and website at antheo.app (the “Service”), operated by Greenlight Software LLC, a Wyoming limited liability company (“Antheo,” “we,” “us,” or “our”). By using the Service, you agree to these Terms. If you do not agree, do not use the Service.

Our Privacy Policy explains how we handle your data and is incorporated into these Terms by reference.

1. Eligibility and accounts

You must be at least 16 years old to use the Service. The Service is intended for adults and is not directed to children. Child-specific accounts are not currently offered.
You may hold one account per person. You are responsible for keeping your login credentials secure and for all activity under your account.
Accounts are currently provisioned by us rather than through open in-app sign-up. We may decline to create, suspend, or close accounts at our discretion, including for breach of these Terms.
You agree to provide accurate information and to keep it up to date.

2. The Service

Antheo lets you create sentences (by typing or recording), have them translated, generate native-speaker audio, and drill them through various playback and training modes.

Translations and audio are generated by artificial intelligence and may be imperfect. Antheo is a tool for listening and speaking practice, not a substitute for professional translation, instruction, or certification. We do not guarantee that any translation, transcription, or generated audio is accurate, complete, or appropriate for a particular purpose. You are responsible for how you use the output.

We may change, add, or remove features over time. We may also suspend or discontinue the Service, in whole or in part, with reasonable notice where practicable.

3. Your content and the licence you grant us

You retain ownership of the sentences, recordings, and other content you create or upload (“Your Content”). We do not claim ownership of Your Content.

To operate the Service, you grant us a limited, worldwide, non-exclusive, royalty-free licence to host, store, reproduce, process, transmit, and display Your Content solely to provide the Service to you, including sending it to the third-party AI and infrastructure providers described in our Privacy Policy (for example, to translate text, transcribe a recording, or generate audio). This licence ends when you delete the relevant content or close your account, except for limited copies retained transiently by providers or as required by law.

You are responsible for Your Content and you represent that you have the rights necessary to provide it and to grant the licence above.

4. Acceptable use

You agree not to:

Use the Service for any unlawful, infringing, harmful, or abusive purpose.
Upload or process content that infringes others’ intellectual property or privacy rights, including recordings of other people made without their consent.
Submit content that is illegal, hateful, harassing, or sexually explicit, or that exploits or endangers minors.
Reproduce copyrighted material systematically; song lyrics are specifically prohibited.
Attempt to circumvent usage limits, security measures, or entitlement checks, or to access the Service in an automated or abusive way.
Interfere with, overload, or disrupt the Service or its infrastructure.

We may remove content and suspend or terminate accounts that violate these rules. We may use automated and human moderation to enforce them.

5. AI output disclaimer

The Service relies on AI models that can produce output that is inaccurate, outdated, inappropriate, or offensive, despite our filters and quality efforts. Output is provided for language-learning practice only and should be used with your own judgment. We are not liable for reliance on AI-generated translations, transcriptions, or audio.

6. Payments and subscriptions

The Service is currently offered free of charge. If we introduce paid subscriptions, the following terms apply:

Billing through the app stores. In-app subscriptions are billed through Apple’s App Store or Google Play, not directly by us. Your purchase is also subject to the relevant store’s terms.
Auto-renewal. Subscriptions renew automatically unless you cancel. You manage and cancel subscriptions in your Apple or Google account settings.
Refunds. Refunds for in-app purchases are handled by Apple or Google under their policies; we generally cannot issue refunds for store purchases directly.
Free tier and limits. A free tier may allow a limited number of sentence creations. Where a creation limit applies, it is counted as a lifetime quota; deleting a sentence frees a library slot but does not restore quota, because the cost of generating that content has already been incurred.
Downgrade. If you stop subscribing, your existing library may be locked and preserved (not deleted), and you revert to the free tier. Re-subscribing restores access. Regardless of lock status, you may always export and permanently delete your data, consistent with our Privacy Policy.

We will give clear notice of pricing and terms before you are charged.

7. Third-party services

The Service depends on third-party providers (including Supabase, Vercel, Anthropic, OpenAI, ElevenLabs, Cloudflare, Google, and the app stores). Your use of the Service may be subject to those providers’ terms, and we are not responsible for their acts or omissions. We are not liable for failures or interruptions caused by third-party services.

8. Availability, warranties, and limitation of liability

The Service is provided “as is” and “as available,” without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or secure, or that translations or audio will be accurate.

To the maximum extent permitted by law:

We will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for loss of data, profits, or goodwill.
Our total aggregate liability arising out of or relating to the Service will not exceed the greater of (a) the amount you paid us for the Service in the twelve months before the event giving rise to the claim, or (b) USD 50.

Some jurisdictions do not allow certain limitations, so some of the above may not apply to you. Nothing in these Terms limits liability that cannot be limited under applicable law, including, where relevant, your mandatory statutory rights as a consumer.

9. Indemnification

You agree to indemnify and hold harmless Greenlight Software LLC and its members and personnel from any claims, damages, liabilities, and expenses (including reasonable legal fees) arising from your misuse of the Service, your violation of these Terms, or your infringement of any third party’s rights.

10. Termination

You may stop using the Service and close your account at any time. We may suspend or terminate your access if you breach these Terms or if we discontinue the Service.

On termination, your right to use the Service ends. We will give you a reasonable opportunity to export your data, after which we will delete Your Content in accordance with our Privacy Policy, subject to limited retention required by law.

11. Governing law and disputes

These Terms are governed by the laws of the State of Wyoming, USA, without regard to its conflict-of-laws rules. Subject to any mandatory consumer-protection laws that apply where you live, you agree that disputes arising out of or relating to these Terms or the Service will be resolved in the courts located in Wyoming, USA.

If you are a consumer in the EU/EEA or UK, you may also have the right to bring proceedings in your country of residence and to rely on mandatory protections of your local law; nothing in these Terms removes those rights.

12. Changes to these Terms

We may update these Terms as the Service evolves. When we make material changes, we will update the “Last updated” date and, where appropriate, notify you. Continued use of the Service after an update means you accept the revised Terms.
