Lienka — baby log

Lienka is a self-hosted baby tracker (nappies, feeds, sleep, walks, baths,
medications, measurements, notes) shared live between the caregivers' phones.
The whole state is one SQLite file on your own machine — no cloud, no accounts,
no telemetry. The server hosts an installable PWA: open http://this-machine:8472/
on each device and pick "Add to Home Screen". Works on iOS, Android and desktop.

After installing, configure it for your family and restart:

sudo snap set lienka users="mama,papa" birth-date=2026-09-17 tz=Europe/Bratislava
sudo snap restart lienka

Data lives in /var/snap/lienka/common/data and survives snap refresh. A plain snap remove leaves an automatic snapshot you can bring back (sudo snap saved, sudo snap restore <set>); sudo snap remove --purge lienka wipes it for good. Timestamps
are wall-clock local, so set tz to your region. Writes are unauthenticated:
run on a trusted LAN or VPN only, never port-forwarded to the internet. For TLS
put the snap behind a reverse proxy (Caddy: reverse_proxy 127.0.0.1:8472).
