1. Information We Collect

Account Information

When you sign up, we collect your email address, encrypted password, and subscription status (Free/Premium). Payment processing is handled by third-party providers (e.g., Stripe); we do not store full credit card numbers.

Usage History (Members Only)

For signed-in users, we save your calculation history and "Favorite" tools to your dashboard. You can delete this history at any time in your Account Settings.

2. AI & Chat Data

If you use our Premium AI Chat features to ask for explanations or complex solutions:

  • Processing: Your queries are sent to our LLM (Large Language Model) providers to generate answers.
  • Retention: We may store chat logs to allow you to review past conversations.
  • Training: We do not use your personal financial or health data to train public AI models.

3. Data Security & Deletion

You have the right to be forgotten. If you wish to delete your account, you can do so from the Settings page. Upon deletion, all personal history, saved calculations, and chat logs are permanently removed from our databases.
