Terms of Service

These terms are a binding agreement between you and the operator of Zonlo. They apply when you use the Zonlo app or this website. By using Zonlo you agree to them. If you do not agree, please do not use Zonlo.

Please read carefully. Section 15 requires most disputes to be settled by binding individual arbitration and includes a class action waiver. You can opt out within 30 days of first accepting these terms.

1. Who provides Zonlo

Zonlo is provided by Corbyn Ledbetter, one person working alone, based in Texas, United States ("Zonlo", "we", "us", or "our"). Zonlo is an app for rehearsing speech: a private space to say a conversation in another language out loud before it happens.

2. Eligibility

You must be at least 13 years old to use Zonlo. If you are under the age of majority where you live, you may use Zonlo only with the involvement of a parent or guardian. By using Zonlo you represent that you meet these requirements and that the information you provide is accurate.

3. Your account

You need an account to save your progress, and some parts work as a guest. Keep the way you sign in secure, because you are responsible for what happens under your account. You can delete your account at any time in the app under Settings. Tell us promptly at support@zonlo.app if you think someone else has been using it.

4. License to use the app

We grant you a personal, limited, nonexclusive, nontransferable, revocable license to use the app on Apple devices you own or control, for your own language practice rather than for business, subject to these terms and the App Store terms. This license is not a sale. All rights we have not expressly granted are reserved.

5. Subscriptions and purchases

The first 5 conversations in each language are free.
Zonlo Pro comes as a subscription that renews on its own, monthly or yearly, or as a single purchase you keep for good. Prices are shown in the app before you buy.
Payment is charged to your Apple account when you confirm. Subscriptions renew on their own at the price current at the time, unless you cancel at least 24 hours before the period ends.
If a free trial is offered, you can cancel at any point during it and pay nothing. Whatever is left of a trial is given up once you buy a subscription.
Manage or cancel in your device's Settings → Apple Account → Subscriptions, or on the Manage subscription screen in the app.
Refunds are handled by Apple under the App Store terms. We do not take payments directly and usually cannot issue a refund ourselves.

6. Acceptable use

You agree not to: disrupt, overload, or try to break into our servers or systems; take the app apart, decompile it, or work around it, except where the law expressly allows; use the feedback service for anything unrelated to language practice, or for unlawful, harmful, or abusive content; resell the app or make money from it; or infringe anyone's rights. We may limit, suspend, or end access that breaks these terms or that we reasonably believe harms Zonlo or the people using it.

7. Content, your submissions & copyright

Our content. The scenarios, phrases, design, software, and other app content belong to Zonlo or its licensors and are protected by intellectual property laws. Nothing in these terms transfers those rights to you.

Your content. "Your content" means anything you send us through Zonlo, mainly the text of what you say and any messages you write to us. You keep whatever rights you have in it. By sending a reply to be checked, you grant us a limited, worldwide, royalty free license to handle that text, pass it to the providers who help check it, and store it briefly, purely to produce and return your feedback and to run, secure, and improve the service. That license ends when the content is deleted from our systems in the ordinary course, except for anything we have to keep to obey the law or settle a dispute.

Content standards. You alone are responsible for your content, and you confirm that you have the right to send it and that it breaks no law and no one else's rights. You agree not to send content that is unlawful, infringing, defamatory, harassing, hateful, sexually exploitative, or that carries malware, or that you know to be false in a way that causes harm. Zonlo is a private tool for practice: your content is never shown to other users, and Zonlo is not a place for publishing anything to the public.

Moderation. We are under no duty to monitor content, but we may review, refuse, limit, or remove any of it, and suspend or end access, if we reasonably believe it breaks these terms or the law or harms Zonlo or other people. Because feedback is produced automatically, nothing is screened before it is sent. To the fullest extent the law allows, we are not liable for content sent by users. Any moderation we do is a right, not a duty, and does not make us responsible for anything we leave up.

Copyright complaints (DMCA). We respect intellectual property rights and answer valid notices under the U.S. Digital Millennium Copyright Act. If you believe content on Zonlo infringes your copyright, send a written notice to our designated agent at support@zonlo.app with the subject "DMCA Notice", including: (a) your physical or electronic signature; (b) which copyrighted work you say is being infringed; (c) which material you mean, with enough detail for us to find it; (d) your contact information; (e) a statement that you honestly believe the use was not authorized by the owner, its agent, or the law; and (f) a statement, under penalty of perjury, that your information is accurate and that you are the owner or allowed to act for the owner. We may take down material said to be infringing, and we may close the accounts of anyone who does it repeatedly. If your material came down by mistake, you can send a counter notice with the same contact and signature details and a statement, under penalty of perjury, that you honestly believe it was removed by mistake. False claims can carry legal liability.

8. Feedback comes from AI, and is not professional advice

Feedback is produced automatically by AI, not written by a person, and it is there to help you learn. It can be imperfect or simply wrong, and it is not professional translation, certification, legal, medical, or any other expert advice. Do not lean on it when something important is riding on the outcome. For a fuller explanation of how AI is used, where it falls short, and what happens to your words, read our AI Disclosure.

9. Services from other companies

Zonlo relies on services run by other companies, including Apple, Clerk, RevenueCat, Google, Amazon Web Services, and Cloudflare. Your use of those services may fall under their own terms, and we are not responsible for them.

10. Apple App Store terms

Because you download Zonlo from the Apple App Store, the following apply and, where they conflict, control over any inconsistent term above:

This agreement is between you and Zonlo only, not with Apple. Apple is not responsible for the app or anything in it.
Your license is limited to a nontransferable license to use the app on devices made by Apple that you own or control, under the App Store's Usage Rules.
Zonlo, not Apple, is solely responsible for the app and for keeping it running and supported. Apple has no duty to provide support.
If the app fails to meet any warranty that applies, you can tell Apple, and Apple may refund what you paid. To the fullest extent the law allows, Apple owes nothing further under any warranty, and any other claims are ours to answer.
Zonlo, not Apple, is responsible for handling any claim about the app, including product liability, legal and regulatory compliance, and consumer protection claims.
Zonlo, not Apple, is responsible for looking into and settling any claim by someone else that the app infringes their intellectual property.
You confirm that you are not in a country under a U.S. Government embargo or named as supporting terrorism, and that you are not on any U.S. Government list of banned or restricted parties.
Apple and its subsidiaries are beneficiaries of these terms and can enforce them against you.

11. Privacy

How we handle data is described in the Privacy Policy. In short: your audio never leaves your phone, and we never sell your data.

12. Disclaimer of warranties

Zonlo is provided "as is" and "as available", with no warranties of any kind, whether stated, implied, or written into law, including implied warranties of merchantability, fitness for a particular purpose, and noninfringement. We do not promise the app will run without interruption or without errors, or that feedback will be accurate. Some places do not allow certain warranty exclusions, so parts of this section may not apply to you.

13. Limitation of liability

To the fullest extent the law allows, Zonlo and the person who runs it will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for lost profits, data, or goodwill, arising from your use of the app or your inability to use it. Our total liability for any claim about Zonlo will not exceed whichever is greater: what you paid us in the 12 months before the claim, or US $100. Nothing in these terms limits liability that the law says cannot be limited, including your rights under consumer protection law.

14. Covering our costs if you cause a claim

You agree to cover Zonlo and the person who runs it against any claims, damages, liabilities, and reasonable costs, legal fees included, that come out of your misusing the app, breaking these terms, or breaking any law or anyone else's rights.

15. Settling disputes, and arbitration

Please read this section carefully. It affects your legal rights.

Let's try to sort it out first. Before starting anything formal, you agree to write to us at support@zonlo.app and give us 30 days to settle the dispute between ourselves. Most things can be settled this way.

Binding arbitration. If we cannot settle a dispute that way, you and Zonlo agree that any dispute arising out of or relating to these terms or the app will be settled by binding individual arbitration rather than in court. The arbitration will be run by the American Arbitration Association (AAA) under its Consumer Arbitration Rules as they stand at the time, available at www.adr.org or by calling the AAA. If the AAA is unavailable or will not run it, we will agree on another established arbitration administrator that applies comparable consumer rules, or a court may appoint one. The arbitration will be seated in Texas or, if you prefer, held by telephone, by video, or in writing, and judgment on the award may be entered in any court with jurisdiction. The U.S. Federal Arbitration Act governs how this section is read and enforced.

Who decides what can be arbitrated. The arbitrator, and not a court, decides everything about how this arbitration section is read, how far it reaches, whether it can be enforced, and whether it was formed. The one exception is that a court decides whether the class action waiver below can be enforced.

Arbitration fees. Who pays the filing, administration, and arbitrator fees is set by the AAA rules. Where those rules or the law require it, we will pay or advance the fees for your individual claim.

Class action waiver. Disputes will be brought by you alone, and not as a lead plaintiff or a member of any class, collective, or representative proceeding, and not as a private attorney general except where that right cannot be given up by law. The arbitrator may not combine more than one person's claims. If a court decides this class action waiver cannot be enforced for a particular claim, that claim, and only that claim, will be split off and may go to court, while everything else stays in arbitration.

Many similar claims at once. If 25 or more similar arbitration demands are filed by, or with the help of, the same or coordinated lawyers, we both agree the AAA will handle them in batches of up to 50 so they can be resolved efficiently, with a single filing fee per batch. This does not create any right to proceed as a class.

Exceptions. Either of us may bring an individual claim in small claims court, and either of us may go to court to stop misuse of intellectual property. Nothing here gives up rights that the law says cannot be given up.

Opting out within 30 days. You can opt out of this arbitration section by emailing support@zonlo.app with the subject "Arbitration opt out" within 30 days of first accepting these terms. Opting out changes nothing else in these terms.

16. Governing law

These terms are governed by the laws of the State of Texas and by U.S. federal law where it applies, without regard to which state's laws would otherwise be chosen. Subject to Section 15, any dispute that does not go to arbitration will be brought only in the state or federal courts in Texas, and you agree to their jurisdiction. Consumer protection rights that the law guarantees you where you live are not affected.

17. Ending your use

You can stop using Zonlo and delete your account at any time. We may suspend or end your access if you break these terms, if the law requires it, or if we shut the service down. Sections that by their nature should outlive that, including who owns what, the disclaimers, the limits on liability, covering our costs, and how disputes get settled, will keep applying.

18. Changes to these terms

We may update these terms as the app changes. If a change matters, we will say so in the app or update the date above. Carrying on using Zonlo after a change means you accept the updated terms.

19. General

These terms, together with the Privacy Policy, are the whole agreement between you and Zonlo about the app. If any part of them cannot be enforced, the rest still stands. If we do not enforce a term straight away, we have not given it up. You may not hand these terms to anyone else. We may hand them on as part of a merger, an acquisition, or a sale of the business. We are not liable for delays or failures caused by things outside our reasonable control.
