Ferne tracks your cycle without an account, without storing anything on our servers, and without pregnancy obsession. We don't ask you to trust us with your data. We make it so that you don't have to.
No spam, ever. Unsubscribe any time.
Every other cycle app is trying to get pregnant — or at least assumes you are. They're built around fertility windows, ovulation predictions, and TTC communities. And somewhere along the way, they decided your health data was a business asset too.
Ferne is for women who just want to know when their period is coming, understand their patterns, and not be surveilled while doing it.
"We don't want your data. We built Ferne so there's no server to breach, no account to hack, and nothing to sell."
Two tiers. No dark patterns, no upsell pressure, no features taken hostage. Free does what it says. Premium earns its price.
