Terms of service
Last updated: August 23, 2026
This page explains in plain language the rules for using Envoz: who can use it, how the memberships and payments work, how to cancel, and what we expect from you when you talk to other people inside the app.
About these terms
Envoz is a service of PF International LLC, a company organized in the state of Wyoming, United States. When you create an account or use Envoz, you accept these terms. If you do not agree with them, do not use the service. These terms are an agreement between you and us, and they work together with our privacy policy, which forms part of them.
Who can use Envoz
You need to be at least 13 years old to have an account. If you are between 13 and 18, you need permission from your parent or guardian, and that person accepts these terms together with you. If you live in a country where the minimum age to agree to a service like this is higher, your country’s age applies. You need to give us truthful information when you sign up, and there is one person per account. If we find that an account belongs to someone below the minimum age, we close it and delete the data.
Your account
Your account is yours and you are responsible for what happens in it, so protect your access and tell us at hola@envoz.io if you think someone else got in. Do not share your account or sell it. You can delete your account whenever you want from the app settings or at envoz.io/eliminar-cuenta, and when you do we delete your data as described in the privacy policy.
The memberships and what they include
Envoz has a free membership, Hobbyist, and two paid memberships: Practice at US$8 per month and Fluent at US$16 per month. Lessons with the trainer, audio lessons, pronunciation practice, and conversations with other people are unlimited on every membership, including the free one. The only thing that changes between memberships is how much time per day you can speak with your voice trainer: Hobbyist comes with a short daily allowance, Practice with a working daily allowance, and Fluent with a generous daily allowance. The daily allowance is counted over a rolling 24 hour window, not from midnight. When your time for the day runs out, your trainer closes the session calmly and you can keep using everything else with no limit. No membership is endlessly unlimited: if use is clearly automated, shared between several people, or resold, we can limit it.
Payments and renewal
Paid memberships are billed monthly and renew on their own until you cancel. If you buy inside the app, Apple or Google charges you, depending on the store you downloaded Envoz from, and that store’s conditions also apply. If you buy from the web, Paddle charges you, acting as the authorized seller and handling any applicable taxes. In all three cases the charge is made by that company and not by us, and it appears on your statement under their name. Prices are expressed in United States dollars; if your payment method is in another currency, the final amount depends on the exchange rate and your bank’s fees, which we do not control. If we change the price of a membership, we tell you beforehand and the new price applies at your next renewal, never retroactively.
How to cancel
You can cancel whenever you want, and you do not have to give us a reason or write to anyone to do it. If you bought inside the app, you cancel from Apple’s or Google’s subscription settings. If you bought from the web, you cancel from the Paddle portal, which you reach from your account settings. When you cancel, you keep access to your membership until the period you already paid for ends, and after that your account returns to the free membership. Cancelling your subscription does not delete your account or your progress: if you also want to delete the account, that is done separately.
Refunds
Refunds are handled by the company that charged you. If you bought inside the app, you request the refund from Apple or Google under their rules. If you bought from the web, you request it from Paddle. If you have a problem and do not know who to write to, write to us at hola@envoz.io and we will help you reach the right place. Beyond what the law of your country requires, we are not obliged to refund a period already started, but we do review it case by case when something went wrong on our side.
The socios program
If you take part as a socio, you earn a 50 percent commission on every payment made by a person who came to Envoz through your link, during their first 12 paid months. The person is tied to the first socio who brought them, and that relationship does not change afterwards. A commission is recorded when the payment happens, is approved once the 14 day refund window passes, and is paid manually once a month, when your approved balance reaches the minimum payout amount; if it does not reach it, it carries over to the next month. We do not pay commission on your own subscription or on accounts created to simulate referrals, and we can void commissions obtained through false information, spam, or promises we did not make. You can leave the program whenever you want, and we can change or end the program with advance notice, honoring commissions already approved.
Envoz is software and it can be wrong
This matters and it is not a legal formality: the Envoz trainer runs on artificial intelligence, and sometimes it says incorrect things. It can give you a wrong grammar explanation, correct something that was already right, or state a fact confidently that is not true. We work hard to prevent this and we treat it as a bug when it happens, but we cannot promise you it never will. Use your judgment, and if something sounds off, ask us or check it against another source. Envoz is a tool for learning, not a certificate, a diploma, or an official assessment of your level, and it does not replace advice from a qualified specialist.
How to treat us and other people
Inside Envoz you can have a profile and talk with other real people, so there are rules. Do not harass, threaten, or insult anyone. Do not send sexual, violent, discriminatory, or illegal content, and do not use Envoz to meet people for romantic or sexual purposes: this is a place to learn languages. Do not impersonate anyone, do not post someone else’s private information, and do not use the service to sell, spam, or defraud. Also do not try to break the service, get into other people’s accounts, copy the system in an automated way, or get around your membership’s limits. If you see something that breaks these rules, report it from the app or write to us at hola@envoz.io. We have no tolerance for objectionable content or abusive people: anything written for other people goes through a filter before it is published, and reports are usually reviewed within 24 hours, removing the content, blocking conversations, or closing the account of whoever broke the rules.
What you write and upload
What you write, record, and upload stays yours. You give us permission to store it, process it, and show it inside the service so that Envoz works: so the trainer can answer you, so your progress is saved, so the person you are talking with can read you, and so we can review conduct reports. That permission lasts while you have the account and ends when you delete it, apart from anything we have to keep by law. Your profile photo and your voice introduction are not public on the internet and are only visible inside the app, as the privacy policy explains. You can delete what you uploaded by deleting your account.
What belongs to us
The app, the site, the lessons, the audio, the teaching method, the Envoz name, and its branding belong to us or to whoever licensed them to us. You can use them to learn, which is what they are for. You may not copy, resell, redistribute, or use them to train another system without our written permission.

Privacy
What data we collect, what we use it for, where it is stored, and how to ask us to delete it is explained in our privacy policy, at envoz.io/privacidad. That policy forms part of these terms.
The service can change or fail
Envoz is a product under development. We add features, change others, and sometimes remove one that did not work. We cannot promise you the service will always be available or that it will never have bugs: we depend on the internet, on the app stores, and on third party services we also do not control. If we remove something important from a paid membership or interrupt the service for a long time, we tell you and we look for a fair solution with you.
Suspension and closing an account
We can suspend or close an account that breaks these terms, puts other people at risk, or uses the service fraudulently. When the situation allows it, we tell you beforehand and explain why, and if you think we got it wrong you can write to us at hola@envoz.io and we will review it. If we close your paid account without you having broken these rules, we refund the part of the period you did not use. You can close your account whenever you want, without explaining anything.
No warranties
Envoz is provided as is. To the extent the law allows, we make no warranty that the service will be uninterrupted, error free, or secure against every risk, or that learning with Envoz will give you a specific result. Learning a language depends above all on you and on the time you put in, and nobody can guarantee you a level.
Limit of our liability
To the extent the law allows, our total liability to you for any claim related to Envoz is limited to what you have paid us in the 12 months before the claim, or to US$50 if that figure is greater. We are not liable for indirect losses, such as lost opportunities, profits you expected, or damages that were not foreseeable. None of this limits our liability for willful misconduct, for fraud, or for anything the law does not allow to be limited.
Your rights as a consumer
Nothing in these terms takes away the rights that your country’s consumer protection law gives you. If any rule in this document conflicts with that law, your law prevails and the rest of the document stays in force.
Governing law
These terms are governed by the laws of the state of Wyoming, United States, without applying its conflict of laws rules, and any dispute is resolved in the courts of that state. This does not affect any right you may have, under the law of your country, to bring a claim before the courts where you live.
Changes to these terms
We can update these terms when the product changes or when the law requires it. The date of the last update is at the top. If the change is significant, we tell you inside the app or by email before it applies, and continuing to use Envoz after that date means you accept the new version. If you do not accept it, you can cancel and delete your account.
