How it works
How Littero works.
Littero is a calm kennel record: every dog, cycle, mating, pregnancy, litter and puppy in one place. Dates are shown as ranges with their uncertainty, and every estimate can be edited.
- 1Dogs
Every profile
Photo, breed, sex, birth date, microchip, pedigree and history as dam or sire.
- 2Cycles
Heat and progesterone
A cycle calendar and progesterone results with a chart.
- 3Pregnancy
Date ranges
Mating to whelping with the expected window, never a single fake date.
- 4Litters
Puppies and weights
Each puppy from birth, with weigh-ins and documents.
Your data, plainly
What stays yours.
Littero is local-first: your kennel record stays on your iPhone, with optional private iCloud sync. There is no Lucernel account and no Lucernel server holding your records.
| Data | Where it is kept | Who can see it |
|---|---|---|
| Dogs, heat cycles, progesterone results, matings, pregnancies, veterinary events, litters, puppies, documents, photos, reminders and settings that you create | Your iPhone, and your private iCloud when sync is on | Only you |
| Purchase status | Apple and RevenueCat | Lucernel sees the subscription status, never your payment details |
| Analytics events | PostHog | Lucernel, without your records and without your name |
| Crash reports | PostHog | Lucernel, to fix the crash |
| Support emails | Lucernel mailbox | Lucernel |
