Questions people actually ask.
If the answer isn't here, write to us. A person reads that inbox.
Getting started
Do I have to make an account?
No. You can set Lumie up and use her without ever signing in, and that is the normal path rather than a lesser one. Signing in exists so a new phone can get your history back — nothing else about the app changes.
What do I get in the first 30 days?
Everything, with no card and nothing to cancel. When the 30 days end the app drops back to the free tier and keeps working. Nothing you logged goes away — you lose the premium extras, not your own data. What premium adds.
I have a new phone. How do I move?
Sign in on the old phone with cloud backup on, then sign in with the same account on the new one. If you never signed in, your history only ever existed on the old device and there is nothing we can recover — that is the trade a local-first app makes, in both directions.
Predictions
How does she work out my next period?
From up to twelve of your past cycles, the most recent weighted heaviest, pulled towards the cycle length you gave her during setup. The answer is a range with a confidence level rather than one confident-looking date, because a single date implies a precision no cycle actually has.
Why does it say she is still learning?
Because she has fewer than two of your cycles to go on, or because yours vary enough that a narrow prediction would be a guess dressed up as a fact. Confidence rises on its own as you log — there is nothing you need to do to fix it.
Why can't I see a fertile window?
Because you told her you are on a method that suppresses ovulation — the pill, the patch or the injection. A window there would be drawn from an ovulation that is not happening, so it is hidden rather than estimated. A copper IUD does not suppress ovulation and is not treated this way.
My cycles are long or irregular. Is that supported?
Yes. Setup accepts anything from 21 to 45 days, and the engine predicts well outside that when your logs say so. Irregularity is detected rather than smoothed over: she widens the range and says the confidence is low instead of quietly picking a date.
Your data
Where does what I log actually live?
On your phone, in an encrypted store whose key is held by the phone's own keystore. Cloud backup is off until you switch it on. With it on, the same records sync so a new phone can restore them.
Can you read it?
Your rows are filed under a one-way hash of your sign-in, computed on our server with a secret the app never sees. There is no email column, no phone number and no address book. The detail is in the privacy policy, which is written to be read rather than survived.
How do I delete everything?
From this website, without installing anything, or in the app under Privacy → Delete account permanently. Both remove every record keyed to you and the sign-in itself. It cannot be undone, and that is not a formality: once the sign-in is gone the hash cannot be derived again, so there is nothing left for us to restore even if you ask.
I used it as a guest and already uninstalled the app.
Your logs went with it — they were only ever on the phone. The anonymous account on our side did not, and you cannot sign in here to remove it, because a guest account has no sign-in. Write to us and we will delete it.
Can I get my data out, or lock the app?
Both. The app exports your daily logs and cycle history as CSV, and it can sit behind your device's own lock — fingerprint, face, or the device PIN — so someone holding your unlocked phone still cannot open it.
What does a partner see if I share?
Only the fields you switch on, and never your symptoms, your notes, anything you said to Lumie, or your exact dates. You can revoke it at any time and their access stops immediately.
Chat and voice
How often can I talk to her?
Five conversations a day on the free tier, unlimited on premium. Holding the mic to speak instead of typing is free either way; her replying out loud, and live back-and-forth voice, are premium.
Can I use Hinglish?
Yes — the whole app is in English and Hinglish, and she answers in whichever you speak to her in. You can switch during setup, or later from your profile.
Is she a doctor?
No, and she will not pretend to be. Lumie tracks and talks. She does not diagnose, and when something you say sounds urgent she stops talking and hands you a real number to call.
Your plan
How do I check which plan I am on?
Your account page shows the plan and the renewal date, read from the same record the app reads. In the app, Sync Account Status pulls the latest.
How do I cancel?
From your account page. Cancelling stops the renewal — it does not cut you off. You keep premium until the period you have already paid for runs out. The refund policy covers the rest.
