Privacy Policy

1. Information We Collect

We collect information you provide directly, including:

• Every calculation you perform
• Every button you click
• Time spent staring at results
• How long you hesitate before pressing equals
• Your mathematical preferences and patterns

2. How We Use Your Information

Your calculation data helps us improve our services, personalize your experience, and understand mathematical trends. We analyze which numbers are most popular (7 is surprisingly common) and which operations cause the most hesitation (division).

3. Information Sharing

We do not sell your calculations. We sell insights derived from your calculations. There's a difference. We may share anonymized data with:

• Payment processors (they need to know you can afford math)
• Cloud infrastructure providers
• Mathematics researchers at leading universities
• Our parent company, if we ever get acquired

4. Cookies

We use cookies to remember your mathematical preferences, track your calculation history, and ensure you don't exceed your monthly allocation. Our cookies are essential for preventing free users from accessing premium precision.

5. Data Retention

We retain your calculation data indefinitely. Math is eternal, and so is our database. If you calculated 2+2 in 2024, we still have that record. Your mathematical journey is preserved forever.

6. Your Rights

Depending on your subscription tier, you may have certain rights:

• Free: Right to perform approximate calculations
• Plus: Right to access your calculation history
• Pro: Right to request data export (PDF, 5-7 business days)
• Enterprise: Right to deletion (subject to 90-day processing)

7. International Users

If you are located in the European Union, you may have additional rights under GDPR. To exercise these rights, please upgrade to our Pro tier, which includes GDPR Compliance Mode™ for an additional €4.99/month.

8. Children's Privacy

calc.company is not intended for children under 13. If we discover a child has been performing calculations without parental consent, we will delete their data and recommend they practice mental math instead.

9. Security

We implement industry-standard security measures to protect your calculations. Your 2+2 is encrypted in transit and at rest. No one will ever know you needed a calculator for that.

10. Contact Us

For privacy-related inquiries, please email privacy@calc.company. Response times vary by subscription tier: Enterprise (24 hours), Pro (72 hours), Plus (1 week), Free (we'll get to it).
