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).

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
If you’re running Kubuntu 16.04 LTS (Xenial Xerus) or later, including Kubuntu 18.04 LTS (Bionic Beaver) and Kubuntu 18.10 (Cosmic Cuttlefish), you don’t need to do anything. Snap is already installed and ready to go.
Versions of Kubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf) don’t include snap by default, but snap can be installed from the command line as follows:
sudo apt update
sudo apt install snapd
