3. Data Collection and Purposes

• Account Creation & Authentication: We use passwordless Magic Links and Google OAuth via Supabase Auth. To identify you and save your streak data, we store your email address and a unique User ID.
• App Progress: We store your streak counts, completion timestamps, and account tier ('free' or 'lifetime') in our secure database hosted by Supabase.
• Payment Processing: Payments are processed via Lemon Squeezy, LLC (Merchant of Record). When you purchase Lifetime Access, Lemon Squeezy collects your billing details. We do not see or store your credit card information; we only receive a confirmation of successful payment to unlock your account tier.
