VivaLingua

Terms & Conditions

Last updated: October 13, 2026

1. COMPANY & OWNERSHIP

Sevenfires AI LLC, located in Wisconsin, United States, is the parent company and owner of the VivaLingua mobile application and the website at vivalingua.app (collectively, the "Service"). References to "we," "us," or "our" in these Terms refer to Sevenfires AI LLC.

2. AGREEMENT TO TERMS

By accessing or using VivaLingua, you agree to be bound by these Terms and Conditions. If you do not agree, do not use the Service.

3. ELIGIBILITY

You must be at least 18 years of age to use this Service, including when you join a call or session as a web guest. By using VivaLingua, you represent and warrant that you meet this requirement.

4. ACCOUNT REGISTRATION

You are responsible for maintaining the confidentiality of your account credentials and for all activities under your account. You agree to notify us immediately of any unauthorized use.

5. PLANS & PAYMENTS

VivaLingua is sold as prepaid minutes. There is no subscription and nothing renews automatically. You buy minute packs when you need them, in the sizes and at the prices shown on the in-app pricing screen, and minutes you have purchased do not expire.

Only the host of a video call or in-person session uses minutes — guests always join free, either with the VivaLingua app or from a web browser using a link the host shares.

We may also grant promotional minutes, such as the minutes given when you confirm your email address at sign-up. Promotional minutes are not purchased, carry no cash value, and expire 90 days after they are granted. Purchased minutes are used only after available promotional minutes.

The welcome minutes offered at sign-up are given once to each person, not once to each account. If you delete your account and sign up again within 12 months with the same email address (including an address that delivers to the same mailbox) or with the same Apple or Google account, the new account does not receive welcome minutes again. You can still use the Service and buy minutes.

Purchases are processed through Stripe, the Google Play Store, or the Apple App Store depending on how you buy, and are subject to that provider's terms. Amounts already paid are non-refundable except where required by law or by the store's own refund policy.

6. ACCEPTABLE USE POLICY

You agree not to use this Service for any illegal activity, harassment, fraud, impersonation, or to transmit harmful or offensive content. The following are also not allowed:

  • Do not create an AI voice from another person's voice. Only your own voice may be used.
  • Do not use the Service to create or spread AI-generated speech that misleads people.
  • Do not use the Service to create synthetic speech of a person without that person's permission.
  • Do not try to bypass our location, age, security or consent checks. Do not use a VPN or a similar tool to bypass them.
  • Do not interfere with the Service, probe it for weaknesses, or overload it.

If you break these rules, we may close your account immediately without a refund. You still get any refund that the law gives you a right to.

7. VOICE TRANSLATION & CONTENT

VivaLingua provides real-time AI voice translation. We do not guarantee 100% accuracy of translations. You are responsible for verifying important communications independently. The translated speech you hear is generated by AI, in a standard voice or in the speaker's AI voice, and the audio file of each translated sentence is marked as AI-generated.

An Audio Only call is a call with sound and no video. Everything these Terms say about video calls also applies to Audio Only calls.

8. AI VOICE

Where it is available, you can create an AI voice that speaks your translated words in a voice that sounds like you, whenever you speak in a call or in-person session, whether you started it or joined it. It is optional, it needs your separate agreement in the app, and the Privacy Policy describes how your recording and voice model are handled.

  • Record only your own voice. You must not record, upload, or try to create an AI voice of anyone else, and you must not use an AI voice to impersonate anyone or to mislead people about who is speaking.
  • When you record, you read aloud four words that the app shows you. They check that the recording was made just now, by one person. You must not try to get around this check, for example by playing a recording.
  • AI voices are offered in most places. They are not offered in China, Malaysia or South Korea. They are not offered in countries and regions under comprehensive United States sanctions. They are not offered in the US states of Illinois, Texas, Washington or Colorado. Do not create an AI voice if you live in one of these places, are in one of them, or use the Service from one of them. Do not use a VPN or a similar tool to appear to be somewhere else.
  • You permit us and our voice provider, ElevenLabs, to use your recording and voice model only to create your AI voice, to speak your translated words to the people you talk to, and to play you a sample; and you permit our speech-to-text provider, Deepgram, to transcribe your recording to check the four words. This permission ends when you delete your AI voice or your account, or when it is deleted automatically as the Privacy Policy describes.
  • People who hear your AI voice hear a synthetic voice saying translated words that you did not record yourself, and VivaLingua shows them an "AI Voice" label. Translations can contain errors, and your AI voice will speak them as translated; verify important communications independently.
  • We may disable or delete an AI voice that is used in breach of these Terms, and we may change or discontinue the feature. You can delete yours at any time in Profile.

9. CALL & SESSION RECORDING CONSENT

You are responsible for obtaining consent from other participants before recording any call or in-person session in jurisdictions where such consent is required. You agree not to attempt to circumvent any security or privacy protections we may put in place. This section is about recordings you make yourself; how VivaLingua processes speech in order to translate it is described in the Privacy Policy.

10. PRIVACY & DATA

Your use of the Service is governed by our Privacy Policy, which is incorporated into these Terms by reference.

11. LIMITATION OF LIABILITY

The Service is provided "as is" and "as available". To the extent the law allows, we disclaim implied warranties.

To the extent the law allows, Sevenfires AI LLC shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of the Service.

To the extent the law allows, our total liability to you is limited to the amount you paid us in the past 12 months. If that amount is less than US$100, the limit is US$100.

Nothing in these Terms limits or excludes any liability that the law does not allow us to limit or exclude. Nothing in these Terms takes away any consumer right that cannot be waived.

12. THIRD-PARTY SERVICES

The Service uses Stripe for payments, Cloudflare to host the Service, Daily.co for video calling and real-time speech-to-text transcription during video calls (via Deepgram), Deepgram for speech-to-text during in-person sessions and to check the words read when an AI voice is created, Google Cloud Translation to translate finalized text, Google Cloud Text-to-Speech and ElevenLabs to generate the spoken translation (which of the two is used depends on the language and on whether the speaker has an AI voice), ElevenLabs to create AI voices, Resend for transactional email, and Expo to deliver push notifications. Use of these services is subject to their respective terms and privacy policies.

13. DIAGNOSTIC AND PERFORMANCE DATA

We collect anonymous technical performance data, which you can turn off in Settings. We also collect a smaller set of diagnostic and crash records that ARE linked to your account, so that a specific failure can be investigated and so that those records are deleted when you delete your account. Neither includes what you said or the text of a translation. Both are described in the Privacy Policy.

14. INTELLECTUAL PROPERTY

All content, features, and functionality of VivaLingua are owned by Sevenfires AI LLC and protected by applicable intellectual property laws.

15. TERMINATION

We reserve the right to suspend or terminate your account at any time for violations of these Terms, with or without notice.

16. GOVERNING LAW

These Terms shall be governed by the laws of the State of Wisconsin, United States, without regard to conflict of law provisions. If you are a consumer, the mandatory laws of the country where you live still protect you. Those laws may also let you bring a claim in the courts of that country.
