Effective November 11, 2026
What are cookies
Cookies are small text files stored on your device that help a site remember who you are and how you use it. Excel Practice Lab uses a small number of cookies, described below.
Cookies we use
| Purpose | Provider | What it does |
|---|---|---|
| Authentication | Supabase | Keeps you signed in between visits. Required for the site to function. |
| Payments | Stripe | Used only on the checkout and billing portal pages to process your Pro subscription securely. |
| Analytics | Microsoft Clarity | Helps us understand how visitors navigate and use the site (clicks, scrolling, session behavior) so we can improve it. Not used to identify you personally or serve ads. |
Managing cookies
You can block or delete cookies through your browser's settings at any time. Blocking the authentication cookie will sign you out and prevent you from staying logged in; blocking analytics cookies won't affect your ability to use the site.
Changes to this policy
We may update this policy if the cookies we use change. We'll update the effective date above when we do.
