Your data stays on your device
Your name, birth date and diary never leave your browser. Every calculation runs locally — we cannot see them.
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.
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, and the study protocol is publicly pre-registered — frozen with a timestamp before any data. 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.
Open by design
The engine and method spec are open source — MIT + CC BY. Don’t take our word for it, verify it yourself. See the code on GitHub.
This isn’t marketing — it’s how the app is built. For the technical detail, see our privacy policy — or explore the engine itself on our open source page.
