Privacy

Last updated 3 November 2026

We keep as little about you as we can.

What we store

• Your Google sign-in is kept in a secure session cookie so you stay signed in. We receive your name and email address from Google and use them to recognise you and to unlock the account that paid.
• Your progress (which lessons you marked done and your mock scores) is kept in your browser. If you sign in with Google it is also saved to your account so it follows you between devices.
• Your theme choice (light or dark) is kept in your browser.

What we do not do

We do not use advertising or tracking scripts, and we do not sell or share your data. Payments are processed by Razorpay; we never see your card or bank details. We store the email address you sign in and pay with so we can recognise your access. We do not receive or store your Google password. Razorpay handles payment data under its own privacy policy.

Where it runs

The site runs on Vercel and keeps access records in an Upstash Redis database. These services process data on our behalf.

Your choices

You can clear your browser data at any time to remove the cookie and the progress stored there. To have a signed-in account’s saved progress deleted, use the contact page.
