Privacy
subtilités is run by Fount Lab. There are no accounts, and we don’t ask for your name or email.
Sentences you type
- To generate the expressions, they are sent to an AI model provider through OpenRouter. They are never sent to providers that train their models on user data.
- Our server doesn’t store your sentences. They may only appear in error logs, which are deleted after 7 days.
- Please don’t include personal information such as names, contact details or addresses.
Prepared examples and quiz
- Picking a prepared example or taking the quiz sends nothing to an AI model: the results are already in the page.
Usage limits and statistics
- To prevent abuse, we count requests per IP address. The count isn’t stored and disappears after a day.
- We count visits without cookies (Umami). Your sentences are not part of it.
What stays in your browser
- Settings such as your screen language and chosen person are kept in this browser and never sent to the server.
