Privacy
Short version: we collect almost nothing, we never sell anything, and you can delete what little we have with one email.
What we store, and why
If you look up prices: nothing. No account, no tracking, no advertising cookies. Your ZIP and your filters stay in your browser. The only thing saved on your device is your light/dark theme choice, and it never leaves it.
If you sign up for price-change emails: we store your email address with Kit, the email service that sends them. Every email has an unsubscribe link that works right away. To delete your address completely, email us and we'll remove it within 7 days.
If you leave your email for the launch notice: we store that email address, plus your browser's user-agent string (a technical detail that helps us block fake sign-ups). We use it to email you when the site goes live. That's all.
If you send feedback through a "tell us" box: we store the message you wrote (500 characters max) so we can fix what's wrong.
What we never do
We don't sell your information. We don't share it with clinics, advertisers, or data brokers. We don't run ads, and we don't build a profile of you.
How to delete what we have
Email hello@thefertilityindex.com from the address you used and we'll delete it within 7 days. Feedback messages can be removed the same way.
