Welcome to 3D Cal. We are committed to protecting your privacy. This Privacy Policy explains how your personal information is collected, used, and disclosed by 3D Cal.

Information We Collect

We collect information in the following ways:

• Information you provide us: When you create an account, you provide us with personal information that includes your display name, email address, and password. If you upgrade to a Pro account, we process transactions through Stripe, but we do not store your credit card details. Your User ID is shared with Stripe to associate the subscription with your account.
• Information from your use of our services: We collect information about the print parameters you enter into the calculator (e.g., spool weight, cost, print time). This data is used to provide you with the cost calculation service and, for Pro users, to provide AI optimization suggestions.
• Cookies and Similar Technologies: We use cookies to operate and administer our Site and to improve your experience on it. We also use Google AdSense, which uses cookies to serve ads based on a user's prior visits to your website or other websites.

How We Use Information

We use the information we collect to:

• Provide, operate, and maintain our services.
• Improve, personalize, and expand our services.
• Understand and analyze how you use our services.
• Communicate with you, either directly or through one of our partners, for customer service, to provide you with updates and other information relating to the website.
• Process your transactions.
• Serve personalized advertisements through Google AdSense.

Third-Party Services

• Firebase: We use Firebase for authentication and database services.
• Stripe: We use Stripe for payment processing for Pro accounts.
• Google AdSense: We use Google AdSense to show ads to non-Pro users. Google's use of advertising cookies enables it and its partners to serve ads to your users based on their visit to your sites and/or other sites on the Internet. Users may opt out of personalized advertising by visiting Ads Settings.
