HandyParken

An unofficial HANDYPARKEN client for Sailfish OS. Opens straight to a parking
timer that books a real session over HANDYPARKEN's own published SMS interface, with HANDYPARKEN's own web portal (account, balance, history) one tap away in native chrome.

Features

- Book a real parking session: pick a duration and, optionally, a licence plate, and Book via SMS opens Messages with HANDYPARKEN's own documented SMS text pre-filled (handyparken.at/meta/faq) — review it and hit send to actually start the permit. The app never sends it itself and cannot confirm HANDYPARKEN accepted it — that only ever shows up in HANDYPARKEN's own  reply SMS and account balance.
- A countdown and a reminder for the session you just booked, set as a calendar alarm on the device — it fires even if the app is not running.
- History of past sessions, kept on the device only.
- HANDYPARKEN's own web portal (handyparken.at), wrapped in native chrome instead of a plain browser tab: a bottom tab bar, a start page you choose, the certificate identity shown outside the page, and a warning when a page is not HANDYPARKEN's.
- You log in to HANDYPARKEN, not to this app — your password goes straight to HANDYPARKEN's own page. The app never injects scripts into it, never reads its contents, and never records where you went.
- Log out clears the session, with an option to do that on every exit.
