Terms of service

Last updated 4 September 2026.

These terms cover the Fuego mobile app and this website. Using either means you accept them. If you do not, do not use Fuego.

Fuego is operated by Filip Kowalski, c/o Coworking Minds, Carrer Ferrers, 1, 07510 Sineu, Islas Baleares, Spain. "We" and "us" in these terms mean that operator.

1. Who can use Fuego

You must be at least 13, and at least the age of digital consent where you live if that is higher. If you are under 18, an adult responsible for you has to agree to these terms on your behalf.

2. Your account

2.1 The App does not require registration. On first launch it creates an anonymous authentication session, and that session identifies your account for as long as you use the App. We do not collect a username, an email address or a password for this purpose.

2.2 Because the account is anonymous, it is bound to the installation that created it. If you delete the App without first deleting your account, we hold no credential by which you can recover the associated learning data, and it cannot be restored to you.

2.3 You are responsible for activity carried out through your account on your device.

3. Charges

3.1 Fuego provides limited access at no charge. Continued access to paid features requires an auto-renewing weekly, monthly or annual subscription offered in the App. The exact products, prices and billing periods available to you appear on the purchase screen before you confirm payment.

3.2 Subscriptions are sold through the App Store or Google Play. Those platforms, and not we, process each payment, renewal and refund.

3.3 The following terms apply to subscriptions:

• the price and billing period will be displayed in the App before you confirm the purchase, and those figures prevail over any statement made elsewhere;
• a subscription renews automatically at the end of each billing period unless cancelled at least 24 hours before that period ends;
• cancellation is made through the subscription settings of your device. Cancellation prevents the next charge and does not withdraw access before the end of the period already paid for;
• Fuego's limited free access is not a store trial, does not collect payment details, and does not convert automatically into a paid subscription; and
• refunds are administered by Apple and Google under their own policies and we are not able to issue one. This does not affect any statutory right of withdrawal or cancellation available to you as a consumer under the law of your country of residence.

3.4 We may change the price of a paid feature. A change takes effect from your next billing period and will be notified to you before it does, so that you may cancel beforehand.

4. Acceptable use

4.1 Voice practice is not metered and the App does not count usage against an allowance. Real-time speech carries a per-minute cost to us, and if we have to introduce a limit we will give notice in the App before doing so.

4.2 You may not access the Service by automated means, script its use, or resell or otherwise make available access to it. We may suspend an account used in breach of this clause.

5. What an AI tutor can and cannot do

Fuego teaches languages. It is not a source of medical, legal, financial, or immigration advice, and you must not treat it as one, even when it answers confidently. It does not replace a certified exam, and passing time with it does not certify your level to anyone.

Tell us when it gets something wrong. The support page explains how.

6. Acceptable use

Do not use Fuego to:

• break the law, or help someone else break it
• harass, threaten, or abuse anyone, including through what you type to the tutor
• generate sexual content involving minors, or content that promotes violence or hate
• extract our prompts, probe the underlying models, or work around usage limits
• upload malware, or attack our servers or our providers
• copy the app, decompile it, or resell any part of it

We can suspend or close an account that breaks these rules. Where the breach is minor and fixable, we will say what is wrong first.

7. Your content and ours

What you write and say in Fuego stays yours. You give us the licence we need to run the service with it: storing it, sending it to the model providers listed in the privacy policy, and generating lessons from it. That licence exists only to operate Fuego for you, and it ends when you delete the content or your account.

We do not train our own models on your conversations.

The app, the site, the name, and the lesson material we author are ours. Lessons and exercises generated for you are yours to use for learning.

8. Availability

We do not promise Fuego will be available without interruption. It depends on services we do not control, including Apple, Google, and our model providers. We will not deliberately break a feature you paid for without telling you.

Features change. We may add, alter, or withdraw them. If we withdraw something central to why you subscribed, cancel and Apple or Google will handle the remainder.

9. Ending it

You can stop at any time: cancel the subscription in your store, and delete your account by the steps on the deletion page. We can close an account that breaks section 6, or if we shut Fuego down. In that case we will give notice and stop charging you.

10. Liability

Fuego is provided as it is. To the extent the law allows, we exclude implied warranties, and we are not liable for indirect or consequential loss, or for anything you did because the tutor told you something incorrect. Where we are liable, our liability is capped at what you paid us in the 12 months before the claim.

Nothing here limits liability that cannot be limited by law, including for death, personal injury, or fraud, and nothing here removes rights you have under the consumer law of the country you live in.

11. Changes to these terms

When we change these terms we update the date at the top. For a change that reduces your rights or raises your costs, we will tell you in the app before it applies. Carrying on using Fuego after that means you accept it.

12. Governing law

These terms are governed by Spanish law. Claims go to the courts of the Balearic Islands, Spain. If you are a consumer, this does not take away the protection of the mandatory law of the country you live in, and you may also bring a claim in your own local courts.
