Draft: have this policy reviewed before launch.

Privacy

We collect your email address when you buy, plus a record of your purchase and any referrals. Payments are handled by Stripe; we never see or store your card details. If you set up referral payouts, Stripe collects your identity and bank details under its own privacy policy.

We use your email to give you access to the app, send login links and contact you about your purchase or referral earnings. We don't sell your information.

Your progress and the numbers you type into the calculators are saved only in your own browser on your device.

To see, correct or delete your information, email brettltcz@gmail.com.
