Draft awaiting review by our accountant (gestoría). It is not final yet, and the details in square brackets still have to be filled in. The Spanish version is the one that applies.
Cookie policy
Draft of 14 October 2026
This website uses no advertising or tracking cookies and no third-party cookies. It stores in your browser only what is strictly needed for the website to work or to remember something you chose. That is why you are not asked for permission (Spain’s LSSI, art. 22.2) and there is no cookie banner.
The public pages (the home page and these legal pages) serve their typefaces from the website itself, so your browser does not contact Google Fonts when you visit them. The lessons area, however, still loads its typefaces from Google Fonts, which receives the device’s IP address; Google Fonts sets no cookies.
Visit statistics use no cookies either: the website only adds up how many times a day the home page is opened or a button is pressed, keeping nothing that identifies the visitor (details in the privacy policy).
What is stored
| Name | Type | What for | How long |
|---|---|---|---|
ld_session | Own cookie, technical | Only if you sign in: carries your sign-in to the server so it opens the lessons area for you. | 1 hour, renewed while the page is open; removed when you sign out. |
cl_lang | Local storage | Remembers whether you chose to see the home page in Spanish or English. | Until you delete it. |
ld_sid_… | Local storage | Student accounts only: identifies this device so the account is open on one device at a time. | Until you sign out. |
ld_role | Local storage | Remembers whether this device opens the student view or the teacher view. | Until you sign out. |
ld_lang, ld_me, ld_best, ld_stab | Local storage | In the lessons area: the language chosen, the practice name and level, best game scores and the last tab opened. | Until you delete it. |
| Firebase sign-in | Browser storage (IndexedDB) | Only if you sign in: Google Firebase’s sign-in service keeps your session there so you are not asked for the password on every visit. | Until you sign out. |
ccl-offline-1 | Service worker cache | Holds only the “offline” page, shown if you open the app without internet. It holds no page with personal data. | Until the website updates or you delete it. |
How to delete it
Pressing “Cerrar sesión” (sign out) removes the sign-in cookie and the account’s data on this device. You can also delete everything this website stores from your browser settings (cookies and site data).
