Cookie policy

• Essential: Firebase Authentication stores a session so you stay signed in and so free AI-coach usage can be tracked fairly.
• Preferences: local storage remembers your calculator inputs and whether you've dismissed the newsletter prompt.
• Analytics: Google Analytics cookies help us understand which pages and tools are useful. IP addresses are anonymised.
• Payments: Stripe sets cookies on its own checkout pages to process payments securely and prevent fraud.

You can clear or block cookies in your browser settings; the calculators still work, but you'll need to re-enter inputs.
