Terms of Service

Last updated 12 October 2026

These Terms of Service (“Terms”) are a legal agreement between you and Kavun, LLC (“we”, “us” or “our”), the provider of ONSET. They govern your use of the ONSET application for Mac, the website heyonset.com and the related online services (together, “ONSET”). By creating an account or using ONSET, you agree to these Terms and acknowledge our Privacy Policy, which describes how we collect and use information. If you do not agree to these Terms, you may not use ONSET.

If you live in the United States, Section 13 requires you and us to resolve disputes by individual arbitration, not in court or in a class action, unless you opt out within 30 days.

You must be at least 13 years old to use ONSET if you live in the United States, and at least 16 years old elsewhere. If you are under 18, or under the age of majority where you live, you may use ONSET only with the permission of a parent or guardian, who agrees to these Terms on your behalf.

1. Your account

You need an account to use the ONSET app. You sign in with your email address and a one-time code that we send to it. You agree to provide an email address that you control, and you are responsible for keeping access to that email account secure, as anyone with access to it can sign in to ONSET as you. You may not allow others to use your account, and you agree to notify us promptly at support@heyonset.com if you believe your account has been accessed without your permission.

2. Your content

A. Ownership

As between you and us, you retain all rights in what you say to ONSET and in the text ONSET writes for you when you dictate (“Your Content”). We do not claim ownership of Your Content. You give us permission to process Your Content, and the information ONSET reads from your screen, as needed to provide ONSET to you, including through our service providers, as described in our Privacy Policy.

B. Examples

Unless sharing is turned off, ONSET sends us examples of its use, which may include recordings and transcripts of speech it hears while it is listening, including what you say to it, dictated text and the speech of other people nearby, as described in our Privacy Policy. You grant us a worldwide, non-exclusive, royalty-free, transferable and sublicensable license to store, reproduce, analyse, modify and otherwise use each example to provide, improve and protect ONSET, including to train and evaluate its models. This license continues for as long as we retain the example. Turning off sharing stops new examples from being sent. During the beta, sharing can’t be turned off in the app; to stop it, email support@heyonset.com.

You agree to pause ONSET, or ask us to turn off sharing, where the law requires the agreement of other people who may be heard and you do not have it.

C. Accuracy of ONSET’s actions

ONSET interprets your requests and acts on your Mac on your behalf, including by clicking, typing, opening, closing, deleting and sending. ONSET may mishear or misinterpret a request, act on the wrong item, or produce text that differs from what you intended, including in ways that cannot be reversed, such as sending a message or deleting a file. ONSET asks for confirmation before some irreversible actions, but not all of them. You are responsible for reviewing ONSET’s actions where accuracy matters, and you should not rely on ONSET alone where an error could cause harm, including in medical, legal, financial or safety-critical matters. ONSET may also respond to speech that was not meant for it, such as other people talking or audio playing nearby.

ONSET is a general-purpose software tool. It is not a medical device, is not intended to diagnose, treat or prevent any condition, and is not certified assistive technology. Do not rely on ONSET as your only way to use your Mac or to call for help in an emergency.

D. Other people

ONSET listens through your Mac’s microphone while it is on, and while it is paused if you turn on “Listen while paused” in ONSET’s Settings. It may hear other people, including people on calls whose voices play through your speakers. In some places the law requires everyone in a conversation to agree before it is recorded. You are responsible for complying with those laws; pause ONSET, or ask us to turn off sharing, when people who have not agreed may be heard.

3. Acceptable use

A. Restrictions

You may use ONSET only in compliance with applicable law. You agree not to:

circumvent or interfere with any security or authentication measure;
decompile, disassemble or reverse engineer ONSET, or extract its models, except to the extent permitted by law;
probe, scan or test the vulnerability of our systems without our prior written consent;
disrupt or overload ONSET or the systems it relies on, including by transmitting malware, sending excessive requests or sending spam;
access our services other than through the ONSET app and our website, including by scraping, by copying or extracting our models or data, or by creating accounts by automated means or in bulk;
sell, rent, sublicense or redistribute ONSET without our prior written consent;
provide false or misleading information about your identity, or impersonate any person;
use ONSET to record, monitor or transcribe other people without any consent the law requires;
use ONSET to create content or carry out actions that are illegal, deceptive or abusive, or to develop AI models that compete with ONSET or our providers;
use ONSET to automate actions that violate the terms of other apps or services; or
use ONSET to violate any law, to harass or harm any person, or to infringe the intellectual property, privacy or other rights of any person.

B. Enforcement

If you violate these Terms, we may take any action we consider appropriate, including suspending or terminating your account.

4. License and updates

ONSET is provided free of charge. Subject to your compliance with these Terms, we grant you a personal, revocable, non-exclusive, non-transferable and non-sublicensable license to install and use the ONSET application on Macs that you own or control.

ONSET downloads the models it requires during setup and when they are updated, and it checks for and installs new versions of itself. If we determine that an update is required, an earlier version may stop operating until the update has been installed.

5. Other apps and availability

ONSET operates the other apps on your Mac, such as email, messaging and web browsers, at your direction. Those apps are not provided by us, and we are not responsible for them, their operation, or their handling of anything ONSET enters into them. Your use of them is subject to their own terms.

ONSET’s online services may be unavailable from time to time, including for maintenance or because of events beyond our reasonable control, and, to the extent permitted by law, we are not liable for any such unavailability.

6. Intellectual property

ONSET, including its software, models, name, logo and website, is owned by Kavun, LLC or its licensors and is protected by copyright, trademark, trade secret and other laws. Except for the license in Section 4, these Terms do not grant you any right, title or interest in ONSET. You agree not to modify, translate or create derivative works of ONSET, except to the extent permitted by law.

ONSET includes open-source software and models provided under their own licences. Those licences govern those components, and nothing in these Terms limits your rights under them.

If you provide us with comments or suggestions about ONSET, we may use them without restriction or obligation to you, including after these Terms end, subject to our Privacy Policy.

7. Changes to ONSET

We may change ONSET, for example to improve it, fix problems, keep it secure or comply with the law, and we may set reasonable limits on the use of ONSET’s online services. If a change materially reduces what you can do with ONSET, we will tell you in advance where reasonably practicable. We may suspend or end your access, or discontinue ONSET, as described in Section 9.

8. Privacy

Our Privacy Policy describes how we collect, use and disclose information when you use ONSET. By using ONSET, you acknowledge that you have read the Privacy Policy.

9. Term and termination

You may stop using ONSET at any time. To delete your account, email support@heyonset.com from the address associated with your account.

We may suspend or terminate your access, with notice where reasonably practicable, if we reasonably believe that you have violated these Terms or that your use of ONSET exposes us or others to risk of harm or loss. We may also discontinue ONSET, in which case we will give you reasonable notice where practicable.

Any provision of these Terms that by its nature should survive termination will survive, including the license you grant in Section 2(B) and the provisions concerning ownership, disclaimers, indemnity, limitation of liability and disputes.

10. Disclaimer of warranties

To the fullest extent permitted by law, ONSET is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose and non-infringement. We do not warrant that ONSET will be timely, uninterrupted or error-free, that it will correctly understand or carry out your requests, that it will meet your requirements, or that it will be free of viruses or other harmful components.

Some jurisdictions do not allow the exclusion of certain warranties, so some of these exclusions may not apply to you. These Terms do not limit any rights you have under the law of your place of residence that cannot be limited by contract, such as the Australian Consumer Law. If you are a New Jersey resident, Sections 10, 11 and 12 apply only to the extent permitted by New Jersey law.

11. Limitation of liability

To the fullest extent permitted by law, we will not be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of profits, revenue, data, use or goodwill, arising out of or in connection with: (a) your use of, or inability to use, ONSET; (b) any action ONSET takes on your Mac or any text it produces for you, including where it has misheard or misinterpreted a request or responded to speech that was not meant for it; (c) the conduct or content of any third party, or any other app or service; or (d) any unauthorised access to, use of or alteration of your information or transmissions, except to the extent caused by our failure to comply with these Terms or applicable law.

To the fullest extent permitted by law, our total liability for all claims arising out of or relating to these Terms or ONSET is limited to the greater of one hundred US dollars (US$100) and the amount you paid us in the 12 months before the claim.

Nothing in these Terms limits liability for fraud, gross negligence, wilful misconduct, death or personal injury caused by negligence, or any other liability that cannot be limited by law.

If you reside in the European Economic Area, the United Kingdom or Switzerland and use ONSET other than for purposes relating to your trade, business or profession, we are liable under statutory law for (i) damage caused intentionally or by gross negligence, (ii) death, personal injury or damage to health, (iii) liability under product liability law, and (iv) for slight negligence, only for breach of obligations essential to these Terms, limited to typical, foreseeable damage.

12. Indemnity

To the extent permitted by law, you agree to indemnify and hold harmless Kavun, LLC and its officers, directors, employees and agents from and against claims, damages, losses, liabilities, costs and expenses, including reasonable attorneys’ fees, arising out of your breach of Section 3, or your violation of any law or of anyone’s rights through your use of ONSET, except to the extent caused by our own fault. This Section 12 does not apply if you are a consumer residing in the European Economic Area, the United Kingdom or Switzerland.

13. Dispute resolution

A. Informal resolution

Before either of us brings a claim, the party with the claim will first try to resolve it informally by sending the other a written description of it: you by emailing support@heyonset.com from the email address associated with your account, and we by emailing that address. If the dispute is not resolved within 60 days of receipt, either party may commence formal proceedings. Limitation periods are paused during those 60 days.

B. Venue

Subject to the arbitration agreement below, you and we agree that any court proceeding arising out of or relating to these Terms or ONSET will be brought exclusively in the state or federal courts located in Delaware, and you and we consent to the personal jurisdiction of those courts. This paragraph does not affect any right you may have under the law of your country to bring proceedings in your local courts.

C. Arbitration for United States residents

If you reside in the United States, you and we agree to resolve any claim arising out of or relating to these Terms or ONSET by final and binding arbitration on an individual basis before a single arbitrator, except as provided under “Exceptions” below. This means that you and we give up the right to have a judge or jury decide the claim. This agreement includes disputes about the interpretation, scope, enforceability or validity of this Section 13, except that a court, not the arbitrator, will decide any dispute about Section 13(D) or about how many related claims may proceed together. The arbitrator may award relief only in favour of you individually and only to the extent necessary to resolve your individual claim. This Section 13 is governed by the Federal Arbitration Act.

Opting out. You may decline this agreement to arbitrate by emailing support@heyonset.com within 30 days after you first create your account or first agree to these Terms. Your email must include your name and the email address on your account and say that you opt out of arbitration. Opting out does not affect the rest of these Terms.
Procedure. The arbitration will be administered by the American Arbitration Association (“AAA”) under its Consumer Arbitration Rules, available at adr.org, and will be held in the United States county in which you reside or work, in Delaware, or at another location to which you and we agree.
Fees. The payment of arbitration fees and costs is governed by the AAA’s rules, including its rules concerning frivolous or improper claims.
Exceptions. Either party may bring an eligible claim in small claims court in Delaware or in the United States county in which you reside or work. Either party may seek injunctive relief in court, without first attempting informal resolution or arbitration, to prevent unauthorised use or abuse of ONSET or infringement of intellectual property rights. If this agreement to arbitrate is found not to apply to you or to your claim, you agree to the exclusive jurisdiction of the state and federal courts located in Delaware.

D. Class action waiver

If you reside in the United States, and to the extent permitted by law, you and we may bring claims against each other only in an individual capacity, and not as a plaintiff or class member in any purported class, consolidated or representative proceeding. Class arbitrations, class actions, private attorney general actions and consolidation with other arbitrations are not permitted.

E. Severability of this section

If any part of this Section 13 is found to be illegal or unenforceable, the remainder will remain in effect, except that if a finding of partial illegality or unenforceability would allow class or representative arbitration, this Section 13 will be unenforceable in its entirety. If you have a non-waivable right to bring a particular claim, or to seek a particular form of relief (such as a public injunction), that the arbitrator may not decide or award under this Section 13, only that claim or request may be brought in court, and it will be stayed until the individual claims in arbitration have been resolved.

14. Changes to these Terms

We may amend these Terms from time to time and will post the current version on this page with the date of its last update. If an amendment materially reduces your rights, we will notify you by email at least 30 days before it takes effect. Amendments apply only from the date they take effect. A change to Section 13 does not apply to any dispute that arose before the change takes effect; such disputes are governed by the version in effect when they arose. If we make a material change to Section 13, you may reject it by emailing us within 30 days, and the previous version will continue to apply to you. By continuing to use ONSET after an amendment takes effect, you agree to the amended Terms. If you do not agree, you must stop using ONSET.

15. Governing law

These Terms are governed by the laws of the State of Delaware, without regard to its conflict of laws principles. Where the law of your country requires that consumer contracts be governed by the law of your country of residence, this section does not override that requirement.

16. General

These Terms constitute the entire agreement between you and us concerning ONSET and supersede any prior agreement concerning it. Our failure to enforce any provision of these Terms is not a waiver of our right to do so later. If any provision is found unenforceable, the remaining provisions will remain in effect and, to the extent permitted by law, the unenforceable provision will be replaced by an enforceable provision that most closely reflects its intent. You may not assign or transfer your rights under these Terms. We may assign our rights to an affiliate or to any successor to ONSET or to the business of which it forms part, provided this does not reduce your rights under these Terms. There are no third-party beneficiaries of these Terms. We may give you notices by email to the address on your account or in the app, and you agree to receive them electronically.

You may not use ONSET if you are located in, or ordinarily resident in, a country or region subject to comprehensive U.S. sanctions, or are on a U.S. government restricted-party list, and you agree to comply with U.S. export and sanctions laws.
