Cookies & Local Storage
What Slí stores on your device, and why
Controller and scope
Slí is operated by Lugha — Learn Upskill Grow Harness AI Limited. This cookies notice explains the small amount of browser storage Slí uses to keep the platform working, remember your consent choice, and improve the product where you have agreed to analytics.
Two categories
Slí stores data on your device in two categories: essential storage required to keep you signed in and the product working, and analytics storage used to improve the product. Your consent choice on first visit determines which optional categories are active.
Essential cookies and storage
These are always active. Without them the product cannot function:
- Session token (cookie) — keeps you signed in. Cleared on sign out or session expiry.
- Active stream (cookie,
sli-active-stream) — remembers which stream you last viewed when you have multiple. Stored for 90 days, refreshed on use. - Cookie consent record (localStorage,
sli.cookieConsent) — records your Accept all / Essentials only choice so we do not re-prompt every visit. - Cross-site request forgery token (cookie) — protects sign-in and form submissions.
Analytics cookies and storage
These are off by default until you choose Accept all on the cookie banner. If you choose Essentials only, none of these are set.
- Product analytics — anonymised usage events such as page views and feature interactions. Used to improve the product. Never includes coaching content or message bodies.
- Error reporting — uncaught errors and stack traces. Used to fix bugs. Stripped of personal identifiers where possible.
No third-party advertising
Slí does not run advertising, retargeting, or ad-network cookies. We do not sell or share your data with advertisers.
Changing your choice
You can change your consent at any time from Profile → Legal & your data → Data & cookies. Your new choice takes effect immediately; analytics cookies are cleared if you switch from Accept all to Essentials only.
Your rights
Under GDPR you have the right to access, correct, export, and delete your data. See Privacy Policy for the full data-rights story, or use Profile → Legal & your data → Download my data / Delete my account.
