<!-- /section:pm-actions -->

<!-- section:outlook -->
### Outlook: Stable

The productivity utility market is consolidating around integrated OS features, leaving Feiertage und Schulferien DE exposed to native platform updates. Sustaining the current one-time purchase model will require consistent, high-value data updates to remain relevant against free, system-level alternatives.

- ⚪ The maintenance-only release cadence (4-week intervals) ensures stability but limits the feature expansion required to capture new market segments.
