1. What cookies are
Cookies are small text files stored on your device when you visit a site. We also use similar technologies — local storage and session storage — which work in much the same way and are covered by this policy.
2. The categories we use
| Category | What it does | Needs consent? |
|---|---|---|
| Strictly necessary | Keep you signed in, refresh the authentication token, protect forms against request forgery, balance load across servers | No — the platform does not work without them |
| Functional | Remember your language, captions and playback speed, sidebar state and where you left off in a video | Yes, where not indispensable |
| Analytics | Understand which features are used and where people get stuck, always in aggregate | Yes |
| Advertising | We use none. We set no advertising cookies and share no data with ad networks | — |
3. Cookies we set
| Name | Purpose | Type | Duration |
|---|---|---|---|
| 3ls_session | Identifies the signed-in session | Necessary | Session |
| 3ls_refresh | Refreshes the authentication token without a new sign-in | Necessary | 30 days |
| 3ls_csrf | Protects against request forgery | Necessary | Session |
| 3ls_lang | Stores the chosen language (PT, EN, FR) | Functional | 1 year |
| 3ls_player | Captions, speed and volume in the video player | Functional | 1 year |

4. Third-party cookies
Video is delivered through the Amazon CloudFront network, which may set technical cookies to authorise access to content and manage delivery. Error logging through Sentry may generate a technical session identifier. Neither is used for advertising.
5. How to control them
- On your first visit we show a notice where you can accept or refuse the non-essential categories. You can change that choice at any time under Settings → Privacy.
- You can block or delete cookies in your browser settings. If you block the strictly necessary ones, you will not be able to stay signed in.
- We honour the Global Privacy Control signal when your browser sends it.
6. Changes
We update this policy whenever the cookies we use change. The date at the top shows the last revision.
