Verified · privacy by design

Trust & transparency

Privacy at aimy.bio isn’t a slogan — it’s built into the architecture. Here is exactly what that means, point by point. Every promise below is something you can check.

Your data stays on your device

Your name, birth date and diary never leave your browser. Every calculation runs locally — we cannot see them.

Zero tracking

No cookies, no ads, no third-party trackers. We even self-host our fonts, so nothing leaks to outside companies.

Anonymous analytics, in the EU

We count visits with Plausible on our own EU server — cookieless, and your IP is used only momentarily and never stored.

The study is 100% anonymous

Optional, double opt-in, off by default. We send only rounded anonymous numbers — never your birth date, ratings or any identifier — and your IP is not logged.

Open and checkable

The research code and data are open. Every promise on this page can be verified — transparency by design, not “trust us”.

Wellness, not medicine

Biorhythms are a tool for reflection, not a diagnosis. We’re honest: the method is not scientifically proven, and we say so plainly.

This isn’t marketing — it’s how the app is built. For the technical detail, see our privacy policy.
