CLEAR ROLES
Flui calculates dates and shows patterns based solely on the data you enter. The app doesn't interpret, advise, or draw conclusions for you. What you do with the patterns is entirely your decision — together with a healthcare professional if needed. Flui is also not a contraceptive method and is not certified for pregnancy prevention.
YOUR DATA, YOUR SERVER
No corporate cloud. No ads. Your data stays yours.
Flui — simple, clear, for you.
