Terms of use

Last updated: November 6, 2026

These are the rules for using lexlex. We wrote them in plain language; if something isn’t clear, write to us at info@lexlex.ca.

1. What lexlex is

lexlex is a service for learning English with content created by artificial intelligence from what you tell us about your life: stories, exercises, explanations and checks of your messages. It is offered by FCOSYSTEMS.

2. Free during early access

For now, lexlex is free, and we don’t ask for a credit card. If it ever has a cost, we’ll let you know well in advance, and we’ll never charge you without your express permission.

3. Your account

• You can use lexlex at any age. If you’re a minor, you need permission from your mother, your father or your legal guardian.
• Use an email address that’s yours and take care of your password: what’s done with your account is your responsibility.
• One account is for one person.

4. Acceptable use

Don’t use lexlex for anything illegal, to damage or overload the service, or to try to get into other people’s accounts or data. When you paste another person’s message into Check as context, do it only if you have the right to share it: we use it to understand yours, and we don’t keep it.

5. Content created with artificial intelligence

lexlex uses artificial intelligence and can make mistakes. Always review a message before sending it: what you send is yours and your responsibility. lexlex is for learning a language; it isn’t legal, medical, financial or any other kind of professional advice.

6. What’s yours stays yours

Your texts and what you tell us remain yours. You give us permission to process them only to provide the service and improve it, as the privacy policy explains. You can download them or delete them whenever you want. You can freely use the content lexlex creates for you to learn and for your own messages.

7. What’s ours

The lexlex brand, its design and its software belong to us. Don’t copy them or use them to create a similar service.

8. Availability and changes

We do our best to keep lexlex working well at all times, but we can’t guarantee that it will be free of interruptions or errors. We may change, improve or remove features; if a change affects you significantly, we’ll let you know.

9. If you want to leave

You can delete your account whenever you want from the Me section. We may suspend an account that breaks these terms, and if we do, we’ll tell you why.

10. Liability

To the extent permitted by law, lexlex is provided as is, and we are not liable for indirect damages arising from its use. Nothing here limits the rights the law gives you as a consumer.

11. Where they apply

These terms apply generally, in any country where lexlex is used. Nothing in them limits the rights the law of your country gives you.

12. Changes to these terms

If we change them, we’ll let you know in the app and update the date above. If you keep using lexlex after the notice, we take it that you accept the new version.
