DACH · Time tracking
ArbeitszeitCheck
Working-time recording that stays in your Nextcloud. Clock-in, breaks, and manual entries; server-side checks against configured DACH profiles (ArbZG, AZG/ARG, ArG); vacation, holiday regions, and reports including DATEV export. Not legal advice — technical rule helpers for your organisation.
What it does
ArbeitszeitCheck helps you apply the working-time rules you configure. Every clock-in is validated by the server against those rules, every change is logged, and every month can be sealed with a verifiable snapshot.
Holiday calendars for DACH
Statutory holiday calendars for Germany (federal states), Austria (Länder) and Switzerland (cantons), including Swiss half-day public holidays where applicable.
Compliance monitoring
Automatic violation detection, manager warnings, and reports — so you can show an auditor what happened and why.
Absence & vacation
Vacation, sickness, special leave with approval workflow. Carry-over with FIFO consumption and configurable expiry (e.g. 31 March).
Vacation entitlement engine
Per-employee mode (manual, model-based, or tariff/rule-based), versioned policies, and traceable calculation snapshots.
Dashboards by role
Employee self-service, team views, manager overviews. Approvals, compliance status, and personal balance at a glance.
Audit-grade closure
Optional revision-safe monthly close: snapshot, hash, PDF proof. Finalised months stay locked until an admin re-opens with justification.
Exports for payroll
Daily / weekly / monthly reports, overtime reports, absence reports, plus a DATEV export for downstream payroll.
HR mail matrix
Configurable admin recipients per absence type and event, with validation, deduplication, and templates for carry-over and substitution events.
GDPR support
Exports, deletion concepts that respect statutory retention, DPIA & records-of-processing templates included.
Legal notice. ArbeitszeitCheck helps you implement technical controls for applicable DACH working-time rules (e.g. ArbZG, AZG/ARG, ArG) and the GDPR (working-time limits, breaks, rest periods, record-keeping). It is not a substitute for legal advice. Employers remain responsible for the design of working-time models, configured limits and retention periods, and the interpretation of recorded data. Review your setup with legal counsel when in doubt.

Official Mobile & Terminal apps
Two mobile apps connect to the open-source server app on your own Nextcloud: a phone app for employees and a foyer time-clock app for shared tablets. Working-time data never leaves your server. See licence & pricing below.
Availability. ArbeitszeitCheck Mobile and Terminal are available for Android on Google Play (free downloads; organisation licence sold separately): Mobile · Terminal. No public iOS release. Screenshots show the German UI. The UIs are translated into 10 languages (DE, EN, FR, ES, DA, NL, IT, PL, SV, NB): on Mobile you can choose under Settings; Terminal follows the tablet’s system language.
ArbeitszeitCheck Mobile — for employees
Clock in and out, manage breaks, review time entries and request absences from your phone. Employees sign in with their existing Nextcloud account; your admin assigns the licensed seats.
ArbeitszeitCheck Terminal — the foyer time clock
A kiosk app for a tablet at the entrance: employees clock in and out with an NFC badge, a USB or Bluetooth card reader, or name + PIN. No personal Nextcloud login is stored on the device.
Licence & pricing
The web app in Nextcloud is free and stays free — open source (AGPL) with the complete feature set. A paid annual organisation licence is only needed for the official Mobile and Terminal apps.
