1. Information We Collect

We collect information you provide directly to us when you create an account, such as your email address and name via our authentication provider (Google/Supabase). We do not store your payment information on our servers; all payment data is securely handled by our payment processor, Paddle.

2. How We Use Your Information

We use the information we collect to provide, maintain, and improve the CALC-PLUS engine, process your transactions, and communicate with you regarding your subscription.

3. Local Computation Data

To ensure your privacy and high performance, mathematical computations and code executed in the CALC-PLUS IDE are processed locally on your device via WebAssembly. We do not transmit or store your personal equations or code on our servers unless explicitly saved by you.

4. Third-Party Services

We may share your information with third-party vendors (such as Supabase for database hosting and Paddle for payment processing) strictly for the purpose of operating our Service.
