At CMD Master, we take your privacy seriously. This policy explains how we handle your data.
We collect minimal data to provide our service: your email address (for account synchronization), progress data (to track lessons), and technical data (cookies and IP addresses for security and analytics).
Your data is used to save your lesson progress, manage your premium subscription, and improve our interactive terminal experience.
We use Firebase for authentication and database management, Stripe for secure payment processing, and Vercel for web hosting and analytics.
We implement industry-standard security measures to protect your data. However, no method of transmission over the internet is 100% secure.
You can delete your account and all associated data at any time through your account settings. You may also request a copy of your data by contacting us at [email protected].
