Cookie policy.

Cookies are small data files a site stores in your browser. We use the minimum we need to make the platform work, and no third-party tracking cookies by default.

SUMMARY
  • · Three cookies, all strictly-necessary or preference — none for tracking.
  • · Quiz progress lives in localStorage on your device, not a cookie.
  • · Any future analytics load only after you consent via the banner.

§01 · Cookies we set.

§02 · localStorage (related, not a cookie).

We store a small amount of data in your browser's localStorage — quiz progress and UI preferences. It stays on your device and isn't sent to our server unless you sign in and choose to sync.

§03 · Third-party / analytics cookies.

We don't currently set third-party cookies. When we add analytics (GA4 or similar) we will:

  • Ask for consent first via a banner — analytics won't load until you accept.
  • List the analytics cookies in this policy.
  • Configure them with IP anonymisation and no cross-site tracking.

§04 · How to manage cookies.

You can clear or block cookies in your browser settings — but blocking strictly-necessary cookies will break sign-in. We don't offer a separate cookie-preferences widget because we don't set non-essential cookies yet. Questions: privacy@tidelab.io.

COOKIES

We use cookies to keep your quiz progress and sign you in. None for advertising, none sold to anyone. Read the policy.
