Privacy policy
Last updated: November 6, 2026
To write content about your life, lexlex needs to know it. Here we explain, with no fine print, what we keep, what for, and how you control it.
In short
- We use what you tell us to create your content and to improve lexlex. We don’t sell your data, and we don’t use it for advertising.
- You see everything we know about you, and you can correct it, hide it or delete it whenever you want.
- You can download your data, start over or delete your account from the app.
- We don’t use tracking cookies or third-party analytics.
- Your data is on a server in Canada. To generate your content, we use OpenAI’s artificial intelligence services.
1. Who is responsible for your data
The organization responsible for your data is FCOSYSTEMS. For any question or request about your data, write to us at info@lexlex.ca.
2. What data we keep
- Your account: your email, your name if you give it to us, your first language, the language you’re learning and the language of the app. Your password is stored transformed with argon2id, a one-way process: nobody can read it, not even us.
- What you tell us about your life: in the first interview, in the chat and while you practice. With it we build your profile: people, places, work, routines, interests and goals. Each piece of information has a sensitivity level.
- Your learning: your answers, your estimated level, the words you look up and practice, the stories you receive and what you think of them, your conversations with the chat teacher and the messages you check.
- Your voice: if you answer by speaking, the audio is turned into text right away and then discarded. Only the text remains, and you can correct it before sending it.
What we don’t keep: the other person’s message that you paste as context in Check (we use it to understand yours, and then it’s discarded). We don’t use tracking or advertising cookies either: your browser only stores your session and your language.
3. What we use it for
- To create your content: your stories, word cards, exercises, explanations and checks.
- To estimate your level and adjust it with what you do.
- To improve lexlex: making sure the content is good and fixing errors.
- To write to you about your account, if needed.
Never for advertising. We don’t sell your data, and we don’t share it with advertisers.
4. Your permission
We ask for your permission before using what you tell us in your content. You can withdraw it whenever you want in the Me section, by turning off “Personalize my content with my life”: your data stays stored, but it’s no longer used in what’s written for you.
5. The most sensitive information
Information about health, religion, political views, sexual orientation, immigration status or minors is marked as restricted and gets extra protection. For example, the names of minors are never written in our technical logs. You can hide or delete any piece of information whenever you want.
6. Who else processes it
- OpenAI (United States) processes what’s needed to generate your content, your audio and the transcription of your voice. Under its API terms, it doesn’t use this data to train its models.
- OVHcloud hosts our server in Beauharnois, Quebec (Canada), where your data and its backups are kept.
Nobody else: no ad networks and no analytics services.
7. Data outside your country
Your data is stored in Canada, and part of it goes to OpenAI in the United States to generate your content. By accepting this policy, you authorize those transfers, which we make only with what’s needed to provide the service.
8. How long we keep it
As long as you have your account. If you delete it, we erase your data from our database at that moment. The audio files generated for you aren’t deleted at that same instant: we remove them later, in a cleanup of the server’s files, and in the meantime nobody can listen to them without knowing their exact address, which is impossible to guess. Backups are renewed every four weeks, so a backup may keep your data for that long at most.
9. Your rights
You can access, correct, update and delete your data, and withdraw your permission, at any time:
- See and correct: the Me section shows everything lexlex knows about you.
- Download: in Me, “Download everything I keep about you”.
- Start over: in Me, “Start over from scratch” erases what you’ve learned and keeps your account.
- Delete your account: in Me, “Delete my account” erases it with all your data.
For any other request or complaint, write to us at info@lexlex.ca. We reply within 10 business days at most. If you’re not satisfied, you can contact the data protection authority in your country: in Canada, the Office of the Privacy Commissioner; in Quebec, the Commission d’accès à l’information; in Colombia, the Superintendencia de Industria y Comercio.
10. How we protect it
All communication is encrypted (HTTPS), passwords are stored with argon2id and access to the server is restricted. No system is infallible: if an incident ever affected your data, we would let you know.
11. Age
lexlex is for people of all ages. If you’re a minor, use it with permission from your mother, your father or your legal guardian. They can ask us at any time to see, correct or delete your data by writing to info@lexlex.ca.
12. Changes
If we change this policy, we’ll let you know in the app and update the date above.
