KnowHer

KnowHer was born from a very specific problem: a developer husband got tired of "getting the timing wrong"—asking about plans on the worst possible day, forgetting birthdays, not realizing it was PMS, and getting scolded for silly things.

Instead of desperately buying more flowers, he opened VS Code.

KnowHer is a (humble) attempt to finally figure out what's going on with your partner before things get out of hand. And if it helps you, maybe it will help other guys too.

WHAT THE APP DOES

• Tracks her menstrual cycle and tells you, every day, what phase of the cycle she's in—menstrual, follicular, ovulatory, or luteal—and what that means for you in practice.

• Notifies you before PMS arrives. Configurable: how many days in advance you want to be notified.

• Reminds you of important dates you "were going to remember but forgot"—her birthday, your anniversary, your wedding anniversary, any date you define.

• For each phase, it shows ideas of what to do, what to avoid, and what can give you extra points. No cliché "buy flowers," just concrete things.

• Daily alerts at the time you choose.

HOW IT WORKS

You open the app, say your name, her name, and the date of her last period. The app calculates the cycle, shows the current phase, and starts notifying you at the right times. That's it.

PRIVACY TAKEN SERIOUSLY

This is an app about a third person (your partner), so we treat the data as sensitive health data. In compliance with the LGPD (Brazilian General Data Protection Law):

• Everything stored encrypted on Google Firebase servers in São Paulo.

• You own your data — you can request complete deletion at any time.

• We do not sell, share for advertising, or create profiles for marketing.

• No ads, no marketing trackers, no hidden charges.

• You need your partner's consent to use it — your responsibility. Full Privacy Policy: https://nicolastroles.github.io/knowher-privacy-policy/

IMPORTANT

• This app is not a medical device, does not replace a consultation, and should not be used as a contraceptive method.

• Intended for users over 18 years of age.

• Accuracy depends on the data you provide.

MADE WITH CARE (AND SOME FEAR)
