Terms of service
Effective Date: April 28, 2026
Last Updated: April 28, 2026
These Terms of Service ("Terms") form a legal agreement between you (or the entity you represent) ("Customer," "you," or "your") and Podonos, Inc. ("Onepin," "we," "us," or "our"). They govern your access to and use of the Onepin website at onepin.ai, our APIs, dashboards, command-line tools, and related services (collectively, the "Services").
By creating an account, accessing the Services, or clicking "I agree," you confirm that you have read and accept these Terms. If you are accepting on behalf of a company or other organization, you represent that you have authority to bind that entity. If you do not have that authority, or if you do not agree, do not use the Services.
For Enterprise customers with a signed master services agreement or order form ("Enterprise Agreement"), the Enterprise Agreement controls if there is any conflict with these Terms.
1. The Services
Onepin is a voice AI orchestration platform. Through the Services we help you:
- Generate audio by routing text and configuration data to one or more third-party text-to-speech ("TTS") engines
- Optimize scripts for pronunciation, accent, and naming
- Use voice cloning by submitting Voice Recordings; the underlying cloning is performed by third-party voice AI providers we route to, and Onepin does not itself train or build voice models on your Voice Recordings
- Validate generated audio using internal models, third-party models, open-source models, and (where applicable) human reviewers
- Apply audio edit to fix issues before audio is returned to you
- Manage projects, voices, and outputs through the Onepin dashboard and APIs
The Services rely on a combination of (i) Onepin's proprietary models and tooling, (ii) third-party commercial AI models accessed via APIs, and (iii) open-source models. The mix of underlying models changes over time as we add, remove, and re-route providers. You should not assume that a specific underlying model or vendor will be available indefinitely.
2. Eligibility and accounts
You must be at least eighteen (18) years old to use the Services. The Services are not intended for individuals under 18.
You must create an account to use most of the Services. Authentication is provided through Google or third-party sign-in; Onepin does not issue or store passwords. You agree to:
- Provide accurate and current information during registration
- Maintain control of the third-party identity provider account (such as Google) you use to sign in, and protect it with appropriate security measures (including a strong password on the upstream account and multi-factor authentication where available)
- Promptly notify us at security@onepin.ai if you suspect unauthorized access to your Onepin account
- Be responsible for all activity that occurs under your account, including activity by your end users
We may verify the information you provide and may refuse to create an account or continue to provide the Services if we cannot reasonably verify it.
2.1 Right to decline or suspend service
We reserve the right, in our sole discretion, to refuse to provide the Services to any person or entity, to decline registration, to cap usage, to require additional identity or use-case verification, or to suspend or terminate access. Reasons may include, without limitation, suspected violation of these Terms or our Acceptable Use Policy, security or fraud risk, repeated billing failures, legal or regulatory concerns, sanctions or export-control restrictions, or our reasonable belief that providing the Services would create unacceptable risk to Onepin, our partners, or the public. Where practicable and not prohibited by law, we will provide notice and an opportunity to address the issue.
3. Plans
The Services are offered in plans described on our pricing page (onepin.ai/pricing) and, for Enterprise customers, in an Enterprise Agreement. Plans differ in rate limits, features, retention, and support level. Enterprise Agreements may include additional commitments (such as a Data Processing Addendum, configurable retention, and the optional limited intellectual-property indemnity described in Section 16.4); in case of conflict between these Terms and an Enterprise Agreement, the Enterprise Agreement controls.
We may add, modify, or remove plans and plan features. If a change materially reduces the functionality of a paid plan during a paid term, you may terminate the affected paid term and receive a pro-rated refund of any pre-paid, unused fees.
4. Customer Content and license
4.1 Definitions
- "Customer Content" means (a) the data you submit to the Services—including text in any format (plain text, CSV, JSON, or other text formats), prompts, pronunciation dictionaries, configuration settings, validation criteria, audio files, video files, Voice Recordings, and other media data—and (b) the audio outputs and validation results the Services generate and return to you. "Customer Content" does not include Onepin's proprietary models, validation tooling, dashboards, code, or documentation.
- "Voice Recording" means an audio recording of a person's or generated voice that you submit to the Services so we can process it and route it to underlying voice AI providers (for example, for validation or voice cloning).
- "Outputs" means generated audio and other content the Services return to you in response to your inputs.
4.2 Ownership
As between you and Onepin, you retain all right, title, and interest in your Customer Content. We do not claim ownership of your Customer Content or your Voice Recordings.
4.3 License to Onepin
You grant Onepin a worldwide, non-exclusive, royalty-free license to host, store, copy, transmit, process, display, and otherwise use your Customer Content **only as needed to provide, secure, support, and improve the Services for you and to comply with law.** This license terminates when you delete the relevant Customer Content or close your account, except for backup copies retained for the limited periods stated in our Privacy Policy and except where retention is required by law.
4.4 Outputs
Subject to your compliance with these Terms, you own the Outputs you generate through the Services, to the extent we have rights to assign. Onepin assigns to you any right, title, and interest it may hold in the Outputs.
Important caveats:
- Commercial use is permitted. Onepin only routes to third-party voice AI providers and open-source models that allow commercial use of the audio outputs they generate for our customers. Some providers may still impose secondary conditions (such as attribution requirements, watermarking, or restrictions on specific content categories); applicable conditions are summarized in our documentation, and you remain responsible for following them in your downstream use.
- Generative AI Outputs may not be unique. The same or similar inputs may produce the same or similar Outputs across different users.
- The legal status of AI-generated content (including its copyrightability and any inherent rights) is unsettled in many jurisdictions. We make no representation about the legal protection available to your Outputs.

5. Voice cloning and biometric data
The Services support voice cloning by routing your Voice Recordings to one or more third-party voice AI providers that generate audio in a voice resembling the speaker. Voice Recordings may be biometric information under U.S. and other laws. The following terms apply when you submit Voice Recordings for cloning or any other voice-emulation feature.
5.1 Required consent
Before submitting a Voice Recording, you represent and warrant that:
(a) You have obtained express written consent from every individual whose voice appears in the Voice Recording, authorizing Onepin to (i) collect and process the Voice Recording, (ii) route the Voice Recording to one or more third-party voice AI providers to generate, validate, or otherwise produce audio outputs that emulate the speaker's voice, and (iii) return those outputs to you for your use through the Services.
(b) Each consenting individual is at least eighteen (18) years old, or, where you are an Enterprise customer with a contractually permitted minor-voice use case, you have obtained verifiable parental or guardian consent in addition to the individual's authorization.
(c) You will retain documentation of that consent and provide it to Onepin within five (5) business days of any reasonable written request, including in connection with an investigation, complaint, or legal demand.
(d) You have all other rights, licenses, and permissions necessary to submit the Voice Recording and to use any Outputs derived from it.
When submitting a Voice Recording for cloning, you will also be required to confirm these representations through an in-product attestation. The in-product attestation does not replace the underlying consent obligations.
5.2 Lawful and responsible use
You are solely responsible for ensuring that any Output generated through voice cloning or any other voice-emulation feature is used lawfully. This means, among other things, that you must not use Outputs to:
- Impersonate any real person without that person's express authorization for the specific use, including for fraud, scams, social engineering, or to obtain anything of value
- Generate content depicting a real person engaged in conduct they did not engage in (so-called "deepfakes") in a manner that is deceptive, defamatory, or unlawful in the relevant jurisdiction
- Influence or interfere with elections, including through synthetic audio of candidates, election officials, or political messaging that omits a clear AI disclosure where one is required by law
- Generate content involving minors in a sexual, exploitative, or abusive manner
- Generate non-consensual intimate audio
- Harass, threaten, defame, or discriminate against any person
- Violate any applicable consumer-protection, telemarketing, robocall, biometric-privacy, intellectual-property, publicity, or right-of-personality law
You agree that Onepin is not responsible for the legality of how you use voice-cloning Outputs, and that you bear sole responsibility for ensuring your use is lawful. Where laws require disclosure that audio is AI-generated, watermarking, or other safeguards, you are responsible for implementing those measures in your downstream use.
5.3 Onepin's protections
We will:
- Treat Voice Recordings as biometric information and a special category of personal data, with the protections described in our Privacy Policy
- Limit access to Voice Recordings to authorized personnel
- Not use Voice Recordings to train Onepin's general models, and engage third-party voice AI providers under contracts that, where reasonably available, restrict the use of Voice Recordings for the providers' own model training
- Suspend or remove access to outputs derived from a Voice Recording on credible reports of unauthorized use of a person's voice and cooperate with reasonable take-down requests
5.4 Take-down requests
If you are an individual whose voice has been submitted to the Services without your authorization, contact privacy@onepin.ai. We will investigate and, where appropriate, delete the Voice Recording, suspend or remove access to associated outputs, and request that any third-party voice AI provider holding a related voice representation do the same.
6. Third-party and open-source models
The Services route requests to third-party commercial models, open-source models, and Onepin-proprietary models. The mix changes over time.
- Commercial-use commitment. Onepin only enables third-party voice AI providers and open-source models that, under their applicable terms or licenses, permit commercial use of the audio outputs they generate for our customers.
- Secondary conditions. Some providers and open-source licenses impose secondary conditions on commercial use (such as attribution, watermarking, or restrictions on specific content categories). Applicable conditions are summarized in our documentation, and you are responsible for following them in your downstream use. Where a third-party term and these Terms directly conflict for a given Output, the more restrictive provision applies to that Output.
- Listed providers and categories. Categories of underlying providers are listed at onepin.ai/subprocessors. Enterprise customers may receive the named provider list under a Data Processing Addendum.
- Routing decisions. We may change which provider receives a given request at any time based on availability, performance, cost, language coverage, or quality. You may not assume that a particular request will be served by a particular provider.
- Model deprecation. See Section 8.
You may not use the Services, the Customer Content you receive back from the Services, or any Outputs to train, fine-tune, validate, distill, or otherwise develop any commercial artificial intelligence or machine-learning model, including any model that is competitive with Onepin, with any underlying voice AI provider, or with any third party. Limited exceptions: (a) where the underlying open-source license that produced the Output expressly permits training, you may use that Output to the extent permitted by that license; and (b) you may use Outputs to fine-tune your own internal-use models that you do not commercialize, license, or otherwise distribute, provided you remain in compliance with all other terms.
7. Acceptable Use
You agree not to use the Services, and not to permit your end users to use the Services, to:
- Violate any applicable law or regulation
- Infringe any intellectual-property right, right of publicity, right of privacy, or other right of any person
- Submit content of, or generate content depicting, minors in a sexual, exploitative, or abusive manner
- Harass, threaten, stalk, defame, or discriminate against any person
- Engage in election interference, political deception, or content suppressing or intimidating voters
- Engage in fraud, deception, scams, phishing, or impersonation, including the unauthorized cloning or impersonation of any person's voice
- Generate or distribute malware, exploit code, or instructions for cyberattacks
- Generate or distribute weapons, hazardous materials, or instructions enabling them
- Provide automated decision-making in legal, financial, medical, employment, housing, credit, or education contexts that produces legal or similarly significant effects on individuals without meaningful human review
- Submit Protected Health Information (as defined under HIPAA) without an executed Business Associate Agreement, or other regulated data without appropriate prior arrangements
- Reverse engineer, decompile, scrape, probe, or otherwise attempt to derive the source code, training data, or architecture of the Services or underlying models
- Resell or sublicense the Services, or use the Services on behalf of a third party in a manner that would obscure that third party's identity or use case
- Interfere with the operation of the Services, including through excessive request volumes, denial-of-service tactics, or sharing API keys
- Use the Services in any country, by any person, or for any purpose subject to U.S. or other applicable export controls or sanctions
A current Acceptable Use Policy is incorporated by reference and may be updated from time to time at onepin.ai/acceptable-use. We may suspend or terminate access for any actual or suspected violation.
8. Service changes, model deprecation, and pricing
8.1 Service changes
The Services evolve. We may add, modify, or remove features, voices, languages, models, or routing options at any time. We will use commercially reasonable efforts to give meaningful notice of material changes that adversely affect existing customers.
8.2 Model deprecation
We routinely add and remove underlying models, voices, and providers. We may deprecate or remove a model, voice, or provider at any time, including (without limitation) when a model is no longer used by a meaningful number of customers, when an underlying provider discontinues or modifies the model, when the model fails our quality or safety thresholds, or when we determine that continued operation is uneconomical or technically infeasible.
For underlying models that are explicitly named in your account or in your Enterprise Agreement, we will use commercially reasonable efforts to give you at least sixty (60) days' written notice before deprecation (by email and in-product notice), and we will identify a recommended substitute where reasonably possible. Shorter or zero notice may apply where (i) the underlying provider gives us shorter notice, (ii) safety, security, or legal concerns require faster action, or (iii) the model is in beta or otherwise designated as experimental in our documentation.
8.3 Fees and payment
Fees are described on our pricing page (onepin.ai/pricing) or in your Enterprise Agreement. Payments are processed by Stripe, Inc. under Stripe's terms and privacy policy; Onepin does not collect or store your full payment card number, CVV, or bank account details.
We may change fees and usage rates from time to time. For paid plans, we will give existing customers at least thirty (30) days' written notice of any price increase, and the new price will take effect at the start of the next billing cycle that begins after that notice period. If you do not agree to the change, you may cancel the affected plan before the new price takes effect; continued use after the effective date constitutes acceptance. Fees for free plans, and pricing under Enterprise Agreements, are governed separately.
Fees are exclusive of taxes, levies, and duties unless stated otherwise; you are responsible for these amounts other than taxes on our income. Failed payments may result in suspension. Fees are non-refundable except as expressly stated in your Order Form or applicable refund policy.
9. Confidentiality
Each party may receive non-public information from the other ("Confidential Information"). The receiving party will (i) use Confidential Information only to perform its rights and obligations under these Terms, (ii) protect Confidential Information using at least the same care it uses for its own information of similar sensitivity (and in any event no less than reasonable care), and (iii) not disclose Confidential Information except to its personnel and advisors with a need to know who are bound by confidentiality obligations, or as required by law.
Customer Content is your Confidential Information. The Services, our pricing, our internal documentation, and unreleased features are our Confidential Information.
10. AI output disclaimer
The Services use machine-learning systems built and operated by Onepin, by third-party commercial providers, and by open-source projects. You acknowledge that:
- Outputs may contain errors, mispronunciations, accent or language inaccuracies, missing or extra words, unnatural prosody, hallucinated content, or other defects
- Outputs may be inappropriate, offensive, or unsuitable for your use case
- Outputs are not, and should not be relied upon as, professional advice (legal, medical, financial, safety, accessibility, or otherwise)
- Validation scores and similar metrics produced by the Services are estimates generated by AI systems and human reviewers; they are not guarantees of quality or fitness for any purpose, and the dimensions we validate may change over time
- Onepin's pronunciation detection and automatic audio corrector automatically modify some audio in an attempt to fix detected issues. These systems may misidentify problems, introduce new artifacts, or fail to catch real defects. The corrected audio is still subject to all of the disclaimers in this Section
- The same or similar inputs may produce different Outputs at different times, and Outputs may not be reproducible
You are solely responsible for validating the accuracy, appropriateness, lawfulness, and suitability of any Output before using it. Where you ship audio generated through the Services to end users, you are responsible for any disclosures, watermarking, accessibility accommodations, or human review your use case requires.
11. Customer responsibilities
You are responsible for:
- Your Customer Content, including ensuring you have all necessary rights, consents, and licenses
- The conduct of your end users, employees, contractors, and anyone you authorize to access the Services through your account
- Maintaining and securing your credentials and devices
- Complying with applicable laws (including export controls, data-protection laws, biometric-privacy laws, telemarketing laws, election laws, consumer-protection laws, and intellectual-property laws) in your use of the Services and Outputs
- Backing up Customer Content; while we maintain reasonable backups for our own operational purposes, we are not your backup of record
- Implementing appropriate disclosures to your end users that audio they hear or interact with is AI-generated, where required by law or context
12. Customer feedback
You may choose to send us suggestions, ideas, or feedback. You grant us a non-exclusive, worldwide, royalty-free, perpetual, irrevocable, sublicensable license to use that feedback for any purpose, including improving the Services. You retain the right to use your feedback for any purpose.
13. Suspension and termination
13.1 Suspension
We may suspend your access to all or part of the Services if (i) we reasonably believe you are in violation of these Terms or our Acceptable Use Policy, (ii) we detect security, fraud, abuse, or operational risk, (iii) your account is past due, or (iv) we are required to do so by law. Where practicable, we will give you notice and an opportunity to remedy the issue.
13.2 Termination
You may stop using the Services and close your account at any time. We may terminate or close your account (i) for material breach of these Terms that is not cured within thirty (30) days of written notice (or immediately for breaches that cannot reasonably be cured), (ii) on at least thirty (30) days' notice for convenience, or (iii) immediately if required by law or if continued provision creates unacceptable risk.
13.3 Effect of termination
On termination, your license to access the Services ends and we will follow the data deletion windows described in our Privacy Policy. Sections that by their nature should survive termination will survive, including provisions on Customer Content licenses (to the extent of remaining backup retention), confidentiality, ownership, AI output disclaimers, warranty disclaimers, limitation of liability, indemnification, governing law, and dispute resolution.
14. Disclaimers
To the maximum extent permitted by law, the Services and all Outputs are provided "AS IS" and "AS AVAILABLE," without warranties of any kind, whether express, implied, or statutory. Onepin disclaims all warranties, including warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy, completeness, reliability, security, and uninterrupted or error-free operation. Onepin makes no warranty regarding the conduct or outputs of any third-party model or open-source model routed through the Services.
Some jurisdictions do not allow the exclusion of certain warranties; in those jurisdictions, the exclusions above apply only to the extent permitted.
15. Limitation of liability
To the maximum extent permitted by law:
- No indirect damages. Neither party will be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, lost revenue, lost data, business interruption, loss of goodwill, or cost of substitute services, even if advised of the possibility of those damages.
- Cap on direct damages. Each party's total cumulative liability arising out of or relating to these Terms or the Services will not exceed the greater of (a) the total fees you paid to Onepin for the Services in the twelve (12) months immediately preceding the event giving rise to the liability, or (b) one hundred U.S. dollars (US$100).
- Carve-outs. The liability cap above does not apply to (i) your obligation to pay fees, (ii) your indemnification obligations under Section 16, (iii) violations of Section 7 (Acceptable Use), or (iv) liability that cannot be excluded or limited under applicable law.
The disclaimers, exclusions, and limitations in these Terms reflect a reasonable allocation of risk in light of the fees you pay (or do not pay) for the Services and form an essential basis of our agreement.

16. Indemnification
16.1 Indemnification by you
You agree to defend, indemnify, and hold harmless Onepin, its affiliates, and their officers, directors, employees, and agents from and against any third-party claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to:
(a) Your Customer Content, including any Voice Recording
(b) Your or your end users' use of the Services or Outputs
(c) Your violation of these Terms, the Acceptable Use Policy, or applicable law
(d) Your violation of any third-party right, including intellectual-property, publicity, privacy, or biometric-privacy rights
(e) Your breach of the representations and warranties in Section 5 (Voice cloning and biometric data)
16.2 Conditions
We will give you prompt notice of a covered claim, reasonable cooperation in the defense, and sole control of the defense and settlement (provided that you may not enter into any settlement that admits fault or imposes obligations on us without our prior written consent).
16.3 Onepin's obligations
Onepin does not, by these Terms, agree to defend or indemnify Customer for any claim arising from Outputs, including any claim that an Output infringes a third party's intellectual-property right or right of publicity. This is because the Services route requests across many third-party and open-source models that are outside Onepin's exclusive control.
16.4 Optional Enterprise indemnity
Enterprise customers may negotiate a limited intellectual-property indemnity from Onepin in their Enterprise Agreement. Any such indemnity will (i) be set out in writing in the Enterprise Agreement, (ii) be subject to negotiated scope and exclusions (typically including, at minimum, exclusions for fine-tuned models, customer-supplied content, third-party model outputs not under Onepin's control, Outputs the customer knew or should have known were potentially infringing, and combinations with non-Onepin materials), and (iii) be subject to a negotiated cap. No indemnity from Onepin to Customer applies absent an Enterprise Agreement that expressly grants it.
17. Governing law and dispute resolution
17.1 Governing law
These Terms are governed by the laws of the State of Delaware, U.S.A., without regard to its conflict-of-laws rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply.
17.2 Informal resolution
Before filing a claim, you agree to try to resolve the dispute informally by contacting **legal@onepin.ai**. We will attempt to resolve the dispute by negotiating in good faith for at least sixty (60) days after notice.
17.3 Binding arbitration
Any dispute, claim, or controversy that is not resolved informally will be resolved by binding individual arbitration administered by JAMS under its Comprehensive Arbitration Rules and Procedures, except that you may bring an individual claim in small-claims court if it qualifies. The arbitration will be conducted in the English language and seated in Wilmington, Delaware (or another mutually agreed location), unless applicable law requires otherwise. Judgment on the award may be entered in any court of competent jurisdiction.
17.4 No class actions
You and Onepin agree that each may bring claims against the other only in an individual capacity, and not as a plaintiff or class member in any purported class or representative action. Class arbitrations and class actions are not permitted.
17.5 Opt-out of arbitration
You may opt out of arbitration and the class waiver by sending written notice to legal@onepin.ai within thirty (30) days of first accepting these Terms.
17.6 Equitable relief
Either party may seek injunctive or other equitable relief in court to protect its intellectual property or confidential information, without first attempting informal resolution or arbitration.
17.7 Jurisdiction
For any dispute not subject to arbitration, the parties consent to the exclusive jurisdiction of the state and federal courts located in the State of Delaware.
18. Changes to these Terms
We may update these Terms from time to time. We will post the updated Terms with a new "Last Updated" date. For material changes, we will give existing customers at least thirty (30) days' notice (by email or in-product notice) before the changes take effect, except where a shorter period is required by law or where the changes relate to a new feature you are not required to use. Your continued use of the Services after the effective date constitutes acceptance.
19. General
- Entire agreement. These Terms (together with the Privacy Policy, Acceptable Use Policy, any Enterprise Agreement, and any policies referenced here) constitute the entire agreement between you and Onepin regarding the Services and supersede any prior agreements on the same subject.
- Severability. If any provision is held unenforceable, the remaining provisions will continue in effect.
- No waiver. Failure to enforce any provision is not a waiver of that provision.
- Assignment. You may not assign these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, financing, reorganization, or sale of assets.
- Force majeure. Neither party will be liable for delays or failures due to causes beyond its reasonable control.
- Independent contractors. The parties are independent contractors. These Terms do not create a partnership, joint venture, agency, or employment relationship.
- U.S. government users. The Services are "commercial products" and "commercial computer software" as defined in applicable federal regulations. Use by U.S. government end users is subject to these Terms.
- Export controls. You will comply with all applicable U.S. and other export-control and sanctions laws and will not use or export the Services in violation of those laws.
- Notices. Legal notices to Onepin must be sent to legal@onepin.ai with a copy to our mailing address. We may give notices to you by email to the address on your account or by posting in the Services.
