Local-first & private
Olee
Every phase, a little less lonely.
A gentle period and cycle tracker for logging what you experience, understanding your patterns and seeing estimates without false certainty. Your sensitive records stay encrypted on your device.
Designed around real life
Track gently. Understand honestly.
Olee helps you keep useful records without turning an estimate into a diagnosis or guarantee.
Honest estimates
See estimated period and fertile-window ranges with uncertainty explained in plain language.
Private by design
Encrypted local storage, PIN and biometric protection, icon disguise and optional duress mode.
Gentle reminders
Opt in only to the period, medication and wellbeing reminders you choose.
Meet Olee (Ollie)
A companion through every phase
Olee is here to make each phase feel a little less lonely—never to judge, diagnose or tell you how you should feel.
Menstrual
A softer place for lower-energy days.
Follicular
Notice changes as a new cycle unfolds.
Fertile-window estimate
An estimate, never a promise or ovulation confirmation.
Luteal
Track patterns without judging how you feel.
Sensitive data deserves restraint
Your cycle belongs to you.
No account. No advertising. No behavioural analytics. No Olee cloud. Your encrypted records remain on your device unless you explicitly export or share them.
