Privacy Policy — Your Data is Secure

At CalcTeacher, we are committed to providing you with powerful tools while maintaining your total anonymity. We believe your calculations are your business, and our policy is simple: We do not harvest your data.

1. Information We Collect

CalcTeacher is a non-membership platform. We do not require you to register, provide an email address, or log in. Therefore, we do not have a database of personally identifiable information (PII).

Calculation Inputs: Your inputs (e.g., your height, weight, loan amount) are processed in real-time to generate your result. These inputs are not stored on our servers once the calculation is complete.
Anonymous Server Logs: Like all websites, our servers record standard, non-identifying data like your IP address (masked), browser type, and time of visit for security and anti-spam purposes.

2. Cookies & Advertising

We use cookies to enhance your experience, specifically for the following:

Preferences: To remember your site settings, such as Dark Mode or your last-used unit system (Metric/Imperial).
Analytics: We use Google Analytics to understand how users interact with our tools. This data is aggregated and anonymized.
Advertising: We use Google AdSense to fund our free tools. AdSense may use cookies to serve personalized ads based on your visits to this and other websites. You can opt out of personalized advertising by visiting Google Ad Settings.

3. GDPR & CCPA Compliance

As a global tool, we respect data protection regulations including the EU General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA):

Right to be Forgotten: Since we do not store PII, there is no profile to delete. Your usage of the site remains truly anonymous.
Data Portability: You may copy your results freely; we do not restrict your access to your own computations.

4. Security

We employ industry-standard SSL encryption (HTTPS) across the entire platform. This ensures that the data you input into our calculators is encrypted while in transit between your browser and our processing engine.

5. Changes to This Policy

We may update this policy periodically to reflect changes in our tools or legal requirements. Your continued use of CalcTeacher constitutes acceptance of the latest policy.
