Notice changes
The expected date and the difference appear side by side. Blue means an earlier start, purple a later one. A clock icon marks an overdue date.
Take your entries with you
Create a backup file and restore it on another device. In the web calendar, you can also connect your own devices with a personal code and encrypted sync.

Android downloads
—Previous download requests on the old domain; not an installation count.
iPhone & iPad

Web browsers
—Browsers and installed web apps that first opened the calendar with counting enabled. Both count once together when they share browser storage.
Loading figures …
What do these numbers mean?
Counting begins on the date shown. Earlier downloads are not included; existing apps count on their first reported launch after that date. Reopening in the same storage does not count again for iPhone or web. Cleared storage, reinstallations and different browsers can count again. Offline use and disabled counting may be missing. These are not verified numbers of people or currently installed apps.
New counting with consent
Statistics are optional and off by default. Make your choice in calendar settings. Open calendar
These are not verified numbers of people or installed apps. Website visits are not counted. Earlier and newer optional totals are separate; offline use may be missing.
YOUR ENTRIES STAY WITH YOU.
Start empty. Bring your history.
An installation never includes another person’s period entries. You can import a backup into Luma to bring your own history.
Create a backup
Export a backup file from Settings in your previous calendar.
Restore in Luma
Open the new calendar and select your backup file using the restore option in Settings.
Connect your own devices
Set up sync in the web calendar and use the same personal code on your other devices. Keep it private.
The browser and Android app may use separate storage. A backup helps when switching. Also create a copy before major updates.
GOOD TO KNOW
Have a question?
Can I use Luma without installing it?
Yes. “Open calendar” takes you straight to the web app. A new installation contains no other person’s entries.
How is the next date estimated?
Without known cycle intervals, Luma uses the adjustable cycle length, initially 24 days. With a history, Luma uses the median of the latest up to six intervals between period starts. The date remains an estimate.
Where is my data stored?
Your entries are initially stored on your device, in the browser or app you use. The web calendar offers encrypted sync using personal codes. Only someone with your code can open the connected data.
Will updates preserve my entries?
Yes, normal updates preserve your saved entries. You confirm new app versions in the calendar or Android update dialog. A backup is recommended before major updates. Do not uninstall or clear browser data.
Are push reminders available?
In the Android app, allow notifications and enable daily reminders starting ten days before the estimated date. They are scheduled on your device. Android may delay them in battery saving mode. You can also enable new version notifications. On iPhone, use the installed web app and allow notifications. Supported browsers can also receive notifications.
Can I download an Android APK for lumarini.com?
Yes. Signed version 1.77 is available for lumarini.com. Install it over the existing Luma app without uninstalling first so local entries remain. The Android web app is available too.
