Terms of Service

Last updated September 15, 2026 · Version 2026-09-15.3

1. Contract and operator

These Terms form a binding agreement between you and AltVoice, the operator of the AltVoice service. By creating an account, clicking an acceptance checkbox, purchasing a plan, or using AltVoice, you agree to these Terms and to the incorporated policies: the Privacy Policy, Cookie Policy, Acceptable Use Policy, Voice Consent Policy, Commercial License, Copyright Policy, Billing Terms, and Refund Policy. If these Terms conflict with a policy, these Terms control except where the policy expressly says otherwise.

Contact: [email protected].

2. Eligibility and authority

You must be at least 18 years old and legally able to enter a contract. If you use AltVoice for an organization, you confirm that you are authorized to bind it. You must provide accurate account and billing information, keep your credentials and connected devices secure, and maintain only one account per person unless we agree otherwise. Creating additional accounts to obtain repeated free allowances or trials, or to evade a restriction, is prohibited.

3. The service and your license

AltVoice provides text-to-speech with library voices, cloning of your own voice from a live microphone recording, designed synthetic voices, sound effects, and related editing tools. Subject to these Terms, we grant you a limited, revocable, non-exclusive, non-transferable license to use AltVoice for lawful personal or internal business purposes. AltVoice and its licensors keep all rights in the software, interfaces, models, workflows, trademarks, and infrastructure.

Features labelled beta, preview, trial, or coming soon are provided for evaluation, may be incomplete, and may change or be withdrawn without notice. Model availability, limits, and supported formats may change as described in section 14.

4. Your content, feedback, and processing license

You retain rights you already hold in your scripts, recordings, and other content. You grant us and our processors a worldwide, non-exclusive, limited license to host, copy, transmit, transform, and process that content only as reasonably needed to provide, secure, troubleshoot, and enforce the service. This license ends when the content is deleted, subject to backups, legal preservation, dispute handling, and the retention periods described in our Privacy Policy.

This license includes creating private synthesis references for your requested generations. It does not transfer ownership of your content or authorize selling your recordings as a dataset, publishing your private voice for other users, or training general-purpose models with your recordings. Any such additional use requires a separate agreement.

If you send us suggestions, ideas, or feedback about the service, you grant us a perpetual, irrevocable, royalty-free license to use them without obligation to you. Feedback does not include your recordings, scripts, or generated audio.

5. Your own voice only

AltVoice clones only the account holder's own voice. A voice reference must be recorded live with your microphone inside the AltVoice interface. Audio files are not accepted as voice references. By recording a reference, you represent and warrant that the voice is your own, that you are speaking live, and that you are not playing back, imitating, or submitting the voice of any other person, including a public figure, client, employee, family member, or fictional character performed by someone else.

Circumventing this rule, for example by routing a recording through a virtual microphone or playing another person's voice into the microphone, is a material breach of these Terms and the Voice Consent Policy. Our failure to detect or block a recording is not approval of it. Voices that are not your own are available only as AltVoice library presets or designed synthetic voices, which are not derived from a specific real person.

6. Outputs, provenance, and required disclosure

As between you and AltVoice, and subject to third-party rights and law, you may use generated output within the license available under your plan and the Commercial License. We do not promise that output is unique, protectable, accurate, non-infringing, or suitable for a particular use. You must review output before publication and clearly disclose that audio is AI-generated or manipulated whenever law, platform rules, advertising rules, or the context requires it, including where listeners could reasonably mistake the audio for an authentic statement by a real person.

Generated audio may carry metadata or other provenance markers that identify it as AI-generated and link it to the generating account. You may not remove, alter, or obscure such markers, and you may not present generated audio as an authentic human recording.

You select the source voice and instructions and decide how, where, and to whom the result is used or distributed. You are responsible for your recordings, statements, publications, calls, messages, and other uses of generated audio, including outside AltVoice. A successful generation, paid subscription, or moderation decision is not an endorsement, certification of permission, or authorization to act for another person. You may not represent that AltVoice approved or participated in your communications or business activities.

7. Prohibited use

You may not use AltVoice for unauthorized impersonation, fraud, scams, fake endorsements, political deception, deceptive robocalls, extortion, harassment, defamation, non-consensual sexual content, exploitation of minors, medical or emergency deception, identity verification, unlawful surveillance, intellectual-property infringement, sanctions evasion, malware, spam, security probing, scraping, quota bypassing, or any use prohibited by our Acceptable Use Policy or applicable law.

You may not use the service or its output to develop, train, fine-tune, benchmark, or improve a voice, speech, or audio model that competes with AltVoice, or attempt to extract model weights, embeddings, training data, or system prompts. You may not access the service through automated means, scripts, or bulk requests except through an interface we designate for that purpose.

8. Review, suspension, and termination

We may reject generations, request evidence, remove or preserve content, limit features, suspend payment-linked access, or terminate an account when we reasonably suspect abuse, fraud, chargeback abuse, security threats, use of a voice that is not your own, legal exposure, or policy violations. We may act without advance notice when delay could create harm, compromise an investigation, or violate law or payment-network requirements. Where appropriate, you may appeal through [email protected].

You must cooperate with reasonable requests concerning your use of the service and must not evade a restriction through another account, device, or third party. We may retain relevant consent and activity records for investigation and the establishment or defense of legal claims, as described in our Privacy Policy. Our moderation controls do not provide a warranty that every violation will be detected or create a contractual undertaking to monitor every use of generated audio.

9. Payments and recurring subscriptions

Paid plans, where offered, are sold and processed by our payment provider acting as merchant of record or payment processor. That provider issues the invoice, collects applicable taxes, handles payment-related customer service, and processes refunds under its own buyer terms. Product support is provided by AltVoice. A subscription automatically renews for the same billing interval until cancelled. The checkout shows the price, currency, taxes, billing interval, and renewal terms before purchase.

The provider's buyer terms and refund policy also apply to the transaction and are linked at checkout. If those terms or mandatory law give you greater rights, those rights control.

10. Plans, minutes, fair use, and top-ups

Plan features and included generation minutes are those shown at checkout and on the Pricing page at purchase. Plan minutes normally reset at each billing period and do not roll over unless expressly stated. Top-up minutes are separate usage capacity and do not change the subscription renewal date. Minute accounting may use completed output duration and reasonable rounding disclosed in the product. You may not resell, pool, or transfer capacity between unrelated accounts.

Features described as unlimited have no fixed monthly cap on the number of generations but are subject to fair use. Requests run in a shared queue, so waiting and processing times vary with load. We may apply rate limits, concurrency limits, queue priority, or temporary throttling, and may restrict accounts whose usage is automated, resold, shared, or materially exceeds ordinary individual or small-team use. Free trials are one per person.

11. Activation, delivery, and failed generations

Paid access is normally provisioned after the payment provider confirms payment and our signed billing event is processed. Brief processing delays do not mean the purchase failed. If paid access is not activated within a reasonable time, contact support with the transaction reference. We will investigate and provide access, replacement capacity, credit, or a refund through the provider where required. A generation that our system records as failed should not consume final minutes; if it does, contact support so we can correct the balance.

12. Cancellations, refunds, and withdrawal rights

You may cancel through the billing area of your account or the provider's customer portal. Cancellation normally takes effect at the end of the paid period, so access continues until then. Refunds and statutory withdrawal rights are governed by our Refund Policy, the provider's terms, and mandatory consumer law. Nothing in these Terms removes a non-waivable right to a refund, price reduction, re-performance, or termination for defective or undelivered digital services.

13. Availability, maintenance, and outages

AltVoice is provided without a service-level guarantee unless we sign a separate written SLA. Planned maintenance, provider outages, capacity limits, security incidents, model failures, network failures, and other events may make the service unavailable or degraded, including for multiple days. We will use commercially reasonable efforts to restore service, but do not guarantee uninterrupted or error-free operation.

For a material outage attributable to AltVoice that prevents use of the core paid service, the ordinary contractual remedy is restoration, replacement capacity, an extension, or a proportionate service credit, as reasonably determined and requested within 30 days. This remedy does not limit refunds or other remedies required by the payment provider's buyer terms or mandatory law, including where delivery fails or is unreasonably delayed.

14. Changes to service, prices, and terms

We may modify or discontinue features, models, limits, and integrations. We will not retroactively increase a completed one-time charge. Price changes for subscriptions apply no earlier than a future renewal and will be communicated in advance where required. Material changes to these Terms will be posted with a new version number and, where required, notified before they take effect. If you do not agree, you must stop using the service and cancel before the next renewal.

15. Third-party services and backups

AltVoice depends on model, hosting, storage, queue, authentication, email, analytics, monitoring, and payment providers. Their outages or policy changes may affect the service. You are responsible for keeping copies of source recordings, scripts, and downloaded outputs; AltVoice is not a permanent archive.

16. No professional or high-risk reliance

Output may be inaccurate, unstable, incomplete, delayed, or unsuitable. AltVoice is not medical, legal, financial, emergency, authentication, biometric-identification, or safety-critical infrastructure. You are solely responsible for human review, permissions, disclosures, and the consequences of publishing or relying on output.

17. Warranty disclaimer

To the maximum extent permitted by law, AltVoice is provided “as is” and “as available,” without implied warranties of merchantability, fitness for a particular purpose, non-infringement, availability, security, data preservation, or output quality, subject to the mandatory protections preserved in section 18.

18. Limitation of liability

Cloning a voice that is not your own, impersonation, fraud, and unlawful distribution of audio are prohibited uses of AltVoice. You are responsible for the consequences of your own conduct. Subject to the mandatory protections below, AltVoice does not assume liability for your violations merely because you used its software to create or process audio.

To the maximum extent permitted by law, and whatever the legal theory, including contract, tort (including negligence), breach of statutory duty, misrepresentation, or otherwise, AltVoice and its operator, personnel, licensors, and suppliers are not liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profit, revenue, goodwill, opportunity, data, or business interruption. Where such a limit is lawful, our aggregate liability to you for all claims arising from or relating to the service will not exceed the greater of USD 100 or the amount you paid for the service during the three months immediately before the event giving rise to the claim. Related claims arising from the same event are subject to one aggregate limit.

Nothing in these Terms or the incorporated policies excludes mandatory consumer rights or liability that cannot lawfully be excluded or limited, including liability for fraud, willful misconduct, gross negligence, or injury to a person. All disclaimers, liability limits, indemnities, and enforcement provisions are subject to this rule.

19. Claims arising from your conduct

You agree to indemnify AltVoice, its operator, personnel, licensors, and service providers against third-party claims, losses, damages, and reasonable defense costs to the extent caused by your breach of these Terms, a false statement that a voice is your own, infringement of another person's rights, or unlawful use of recordings or output. Covered costs include reasonably incurred legal, expert, and investigation expenses, judgments, and settlements approved under this section. This obligation applies to your conduct before and after downloading, sharing, or publishing the audio and survives account deletion.

We will notify you of a covered claim and may control its defense with reasonably selected counsel. You must provide relevant records and reasonable cooperation and may participate in the defense. Neither party may settle a claim in a way that admits fault, imposes a non-monetary obligation, or creates an indemnity payment obligation for the other without that party's written consent, not to be unreasonably withheld. Recoverable amounts must be reasonably incurred and attributable to the conduct covered by this section.

20. Force majeure

Neither party is liable for delay or failure caused by events beyond its reasonable control, including natural disasters, war, civil disorder, sanctions, government action, utility or internet failures, widespread cloud outages, provider shutdowns, labor disruption, or denial-of-service attacks. Payment obligations already due and mandatory refund rights are not excused by this section.

21. Ending the agreement

You may stop using AltVoice and cancel future renewals at any time. On termination, your right to use the service ends, but provisions on payments already due, ownership, evidence preservation, disclaimers, liability, indemnity, disputes, and enforcement survive. Account deletion is subject to limited retention required for billing, fraud, security, disputes, and law.

22. Notices, complaints, and voice-rights reports

Send product and billing-support questions to [email protected], privacy requests to [email protected], and voice-rights or abuse reports to [email protected]. We may send notices to the email address on your account, and you agree to receive contractual notices electronically. Please give us a reasonable opportunity to investigate and resolve a dispute before escalating it.

A voice-rights notice should identify the disputed material, the rights asserted, the factual basis for the claim, the requested action, and the sender's contact details and authority to represent the affected person. Submit notices through our report form or the contact above. We may request clarification and supporting evidence. The review procedure is set out in our Voice Consent Policy.

Receipt or review of a notice, a request for information, or a temporary restriction does not by itself constitute an admission of infringement, fault, or liability, or a waiver of our rights or defenses. An allegation or payment demand alone does not establish an obligation to compensate the sender or suspend unrelated users or the service. We assess the facts and take action required by applicable law; legally binding orders remain effective.

23. Governing law and disputes

These Terms are governed by the law of the country in which the AltVoice operator is established, without regard to conflict-of-law rules. Courts located in the operator's principal place of business have jurisdiction to the extent permitted by law. Consumers keep any mandatory protections and forum rights that apply in their country of residence, including the right to bring proceedings in their local courts where law so provides.

To the extent permitted by law, you and AltVoice agree that any claim will be brought only in an individual capacity and not as a plaintiff or class member in any purported class, collective, or representative proceeding, and that any claim arising from or relating to the service must be commenced within one year after it arose or be permanently barred. These limits do not apply where they are prohibited for consumers in your country of residence.

24. General

Using AltVoice does not create an agency, partnership, employment, or joint-venture relationship. You have no authority to bind AltVoice or make commitments on its behalf. Except for the persons expressly protected by sections 18 and 19, these Terms do not grant additional contractual benefits to third parties.

If a provision is unenforceable, it will be limited to the minimum extent necessary and the remaining provisions continue. Failure to enforce a provision is not a waiver. You may not assign this agreement without our consent; we may assign it as part of a merger, reorganization, financing, or sale of the service, subject to law. These Terms and the incorporated policies are the entire agreement about the service unless a separate signed agreement applies.
