Privacy Policy

What we collect

By design, all calculations happen in your browser. We do not store the numbers you enter into any calculator. The only personal data we collect is what you explicitly submit — your email or phone number — when you ask for a PDF report or sign up for Pro.

How we use it

• To send you the requested PDF report.
• To send occasional educational content (you can unsubscribe with one click).
• To improve our calculators (aggregate, anonymous usage analytics via PostHog).

What we never do

• Sell your data to third parties.
• Share individual calculations with anyone.
• Track you across other sites with cookies you didn't consent to.

Your rights

Email privacy@dhancalc.com to access, export, or delete any data we hold about you. We will respond within 7 days.
