Privacy Policy

1. Who We Are

WhichGrammar is operated from London, United Kingdom. When we refer to “we”, “us” or “our” in this policy, we mean WhichGrammar.

2. Information We Collect

We may collect the following information:

• Account information: name and email address when you register.
• Postcode data: postcodes you enter for the Chances Calculator. These are geocoded via postcodes.io and are not stored with your account.
• Usage data: pages visited, features used, and device/browser type via analytics cookies.
• Payment data: handled entirely by Stripe. We never see or store your card details.

3. How We Use Your Information

• To provide and personalise the service (chances calculations, AI advice).
• To manage your account and process payments.
• To send service-related communications (password resets, billing).
• To improve the platform through aggregated, anonymised analytics.

We will never sell your personal data to third parties.

4. Data Storage & Security

Your data is stored securely using Supabase (hosted on AWS in the EU region). All connections use TLS encryption. We follow industry-standard security practices to protect your information.

5. Cookies

We use essential cookies for authentication, session management and processing subscriptions — these are required for the site to work and cannot be switched off. We use optional analytics cookies only if you accept them in the cookie banner shown on your first visit; if you choose “Essential only”, no analytics cookies are set. You can change your choice at any time by clearing this site's data in your browser.
