Cookie Policy

1. What this page covers

This page explains how Grasp Maths uses cookies and similar browser storage technology across the marketing website (www.graspmaths.com) and the practice platform (app.graspmaths.com). We keep this deliberately short because we only use what's strictly necessary to run the service — no advertising or analytics tracking.

2. Marketing website

The marketing website does not use advertising cookies, analytics cookies, or any third-party tracking scripts. The only browser storage in use is:

• A local storage queue for form submissions. If the Contact or Get Early Access form can't reach our database immediately (for example, if your connection drops), your browser temporarily stores the submitted details on your own device using local storage, so nothing is lost. This data stays on your device and is not a tracking cookie.

3. Practice platform (app.graspmaths.com)

Signing in and using the practice platform sets:

• Essential session/authentication cookies, provided by our backend platform, Supabase, so you stay signed in to your account securely.
• Essential payment-processing cookies, provided by our payment provider, Stripe, only on their own hosted checkout page during subscription sign-up — not on our site.

We also use browser local storage (not cookies) to remember your place in an in-progress practice session on your own device, so you can safely refresh the page or reconnect without losing progress.

These are all strictly necessary cookies/storage required to operate an account-based service — not used for advertising or cross-site tracking.

4. Controlling cookies and local storage

You can control or clear cookies and local storage at any time through your browser's settings. Clearing your authentication cookie will sign you out; clearing local storage may lose an in-progress, unsaved practice session on that device, but won't affect your saved account or progress data, which is stored securely on our servers.

6. Changes to this policy

We'll update this page whenever the cookies or storage technology we use changes, particularly as account and payment features launch.
