Cookie policy
Last updated: 1 November 2026 · Versión en español
- Langueo does not use cookies of its own, nor any advertising or analytics cookies.
- Your browser stores some technical data and your preferences on your own device so the site works. These are exempt from consent because they're necessary or requested by you, which is why you don't see a cookie banner.
- You can delete them at any time from your browser.
1. What are cookies and similar technologies?
Cookies are small files that a website stores in your browser. Similar technologies, such as local storage, IndexedDB or the app cache, also store information on your device. EU and Spanish law (Art. 22.2 of Law 34/2002, LSSI) treats them the same way as cookies.
2. What does Langueo store on your device?
Everything below is technical or a preference you choose. Under the LSSI and the Spanish Data Protection Agency's guidance, this kind of storage does not require your consent. None of it is used to track you or show you ads.
| Name | Type | Purpose | Duration |
|---|---|---|---|
theme |
Local storage, first-party | Remembers whether you chose the light or dark theme | Until you delete it |
langueo-ui |
Local storage, first-party | Remembers the homepage language you chose (Spanish or English) | Until you delete it |
langueo-errores-… |
Local storage, first-party | Stores the conjugations you got wrong so you can review them (“Your mistakes”). It never leaves your device. | Until you fix or delete them |
francais-v… |
App cache, first-party | Stores pages so the site loads fast, works offline and can be installed as an app | Until the next version of the site |
langueo-sesion |
Local storage, first-party | Shows your name, photo and plan in the account menu (top right) without loading the sign-in on every page. Only exists if you sign in. | Until you sign out |
firebaseLocalStorageDb |
IndexedDB, Firebase (Google) | Keeps you signed in. Only present if you sign in with Google. | Until you sign out |
3. Third-party services
The site doesn't load content from other services (fonts are served from our own domain). The exceptions are optional and only happen if you use them:
- Google sign-in: when you sign in, a Google window opens, which may use Google's own cookies to identify you. Those cookies are managed by Google under its cookie policy. While you are signed in, your profile photo is loaded from Google's servers.
- Premium payments with Stripe: if you decide to subscribe, you pay on a Stripe page (checkout.stripe.com) and manage your subscription in its customer portal. Stripe uses its own cookies there, needed for the payment and to prevent fraud, under its cookie policy. No Stripe code is loaded on langueo.com.
More details about the data we process in the privacy policy.
4. How to delete this data
You can delete it at any time from your browser settings, in the privacy or site data section:
If you delete it, the site will keep working, but it will forget your preferences and saved mistakes, and you'll need to sign in again.
5. Changes to this policy
If we ever add cookies that require consent (for example, analytics), we will update this page and ask for your permission before using them.
