About this translation
In short
We do not use advertising, tracking or analytics cookies that identify you. That is why we do not show a consent banner: we only use what is strictly necessary or what you asked for.
What we keep in your browser
| Name | Type | What it is for | How long |
|---|---|---|---|
| lumos-theme | localStorage | The theme you chose (light or dark). | until you delete it |
| lumos-text-size | localStorage | The text size you chose in the accessibility panel (normal or larger). | until you delete it |
| lumos-a11y | localStorage | The accessibility options you chose in the panel: high contrast, highlighted links, easy-to-read font, no animations. | until you delete it |
| crypto.v1 | localStorage | Your progress in the lessons: the lessons ticked as finished and the last score on each lesson's quiz, with the date. It stays in your browser only and is sent nowhere; you can erase it from a track page with "Erase the progress in this browser". | until you delete it |
| lumos-lang | localStorage | The language you chose (Romanian or English). | until you delete it |
All of them are strictly necessary or do what you asked for (for example the language or theme you chose), so the law does not require your consent.
How to delete them
You can delete cookies and site data from your browser settings at any time. If you do, the site forgets you: it goes back to the default language and theme.
