Cookies

Theme

If you choose the light theme, the browser stores that choice so the next visit matches. If you clear site data, the site returns to the dark theme.

Language

If you switch between English and French, that choice is stored in the browser the same way. It is only used to show the language you picked.

Session

If you sign in, a session token is kept in local storage so the lab desk knows it is you. Logging out removes it. We do not use that token to sell data or to build an advertising profile.

What we do not store here

These values are not sold. A quotation, a lab registration, and an account are kept as form records, not as advertising cookies. To delete them, use the contact form.
