We build useful apps around one question: what information can stay on your device instead of being collected? No accounts. No ads. No data leaving your phone.
Our apps work immediately. There is nothing to sign up for and no password to forget.
Your data is encrypted locally. We do not receive it, we cannot see it, we cannot lose it.
No ads, no tracking, no monetization of behavior. A simple, honest product.
Every app we build starts from the assumption that your personal information is none of our business.
A fully featured cycle and symptom tracker. Logs symptoms in under 3 seconds. Predicts cycles. Generates health reports. Encrypted with AES-256 — locally, on your device. No account. No cloud. No ads.

We think privacy-first software should be the default, not a premium feature.
We start every design by asking what information we can leave out. If your app doesn't need to know something, we don't ask. If the server doesn't need it, it never leaves your phone.
Privacy policies should be readable, not legal armor. We write ours in plain language and make them short enough to actually read. We document our encryption and let security researchers examine our code.
Our apps are used by people, and people are the best source of ideas. We read every piece of feedback and take it seriously — even when it's critical. Good software is never finished.
Our first app is available now for iOS and Android. Free to download, no account required.
