Hi, I'm Lisa.

I built Aura Cycles because I was tired of fighting my own body.

I lift weights. One week I hit a number easily. The next week, the same weight, I felt foggy and it would not move. I could not figure out why. Then I checked my calendar. I was in a different part of my cycle.

That was the moment. If I could plan my training, my food, and my social life around my cycle, I could stop guessing and start working with my body instead of against it.

I looked for an app that did this. The good ones cost two hundred dollars a year, and they still wanted my cycle data in their cloud. I did not want to pay for that. And I did not want my data anywhere but on my own phone.

So I built Aura. A deterministic engine. No accounts. No cloud. No login. Everything runs in your browser, on your device.

Most cycle apps are built for women in their twenties. Our cycles do not stop mattering after forty. Perimenopause changes everything, and that is exactly when you need to know your body best. Aura handles perimenopause and menopause, not just regular cycles.

Because your cycle is none of our business. Here is the honest version:

Your period dates, your symptoms, your notes. They all live in your browser's local storage and never get sent to us. We do not have a database of your data because we never collect it. There is nothing for us to sell, and nothing for a hacker to steal.

That is not a feature we bolted on later. It is the whole design.
