Privacy Policy

Information we collect

• Google account (sign-in): When you choose “Continue with Google”, we receive your name, email address, and profile picture from Google via Supabase Auth. We use this to identify your account and tie your founding member pass to you across devices.
• Progress: We store lesson and atom mastery progress linked to your account so you can continue where you left off.
• Payments: If you purchase a founding member pass, our payment provider (Cashfree or Razorpay) processes the transaction. We store a payment reference and entitlement status so we can unlock paid content. We do not store full card or bank details on our servers.
• Anonymous browsing: Before you sign in, we may create a temporary anonymous session so free lessons and progress work in your browser. If you later sign in with Google, we link that anonymous progress to your registered account where possible.

How we use your information

• Authenticate you and manage your account
• Grant access to paid content you have purchased
• Save and restore your learning progress
• Respond to support requests and restore access when needed
• Operate, secure, and improve the service

Where data is stored

Account, progress, and entitlement data are stored in Supabase (hosted PostgreSQL and Auth), with infrastructure provided by Supabase and our hosting provider (Vercel). Payment processing is handled by Cashfree and/or Razorpay under their respective privacy policies.

Sharing with third parties

We do not sell your personal information. We share data only with service providers needed to run Lemma (authentication, hosting, payments) and when required by law.

Cookies and sessions

We use cookies and similar storage to keep you signed in and to maintain anonymous sessions for free lessons. You can sign out at any time from the site header or your account page.

Your choices

You can sign out of Lemma at any time. To request access deletion or export of your account data, email us at abhicoders@gmail.com. We will respond within a reasonable time.

Children

Lemma is intended for exam candidates and is not directed at children under 13. We do not knowingly collect personal information from children under 13.

Changes

We may update this policy from time to time. The “Last updated” date at the top will change when we do.
