Privacy Policy

Last updated August 5, 2026

What we collect

Anonymous visitors can read free lessons without an account. When you create an account, we process your email address, optional display name, lesson progress, reading position, and bookmarks. If you purchase Premium, Dodo Payments processes billing details and sends us subscription identifiers and status. We do not store full card details.

Why we use it

We use account data to authenticate you, synchronize learning progress, provide purchased access, prevent abuse, support billing, and operate the platform.

Service providers

Supabase provides authentication and application data storage, Dodo Payments provides checkout and subscription management, and Vercel hosts the web application. Each provider processes data under its own terms and privacy commitments.

Retention and choices

Learning records remain while your account is active. Billing records may be retained as required for financial, tax, fraud, or legal obligations. Contact the site operator to request access or deletion. Subscription cancellation is available through the billing portal.

Security and contact

We use access controls, signed webhooks, encrypted transport, and least-privilege credentials. No system is risk-free. Replace this launch-ready summary with operator contact details and jurisdiction-specific legal review before accepting live payments.
