HK Kalender

HK Kalender is a fast, private Android calendar for managing daily notes, work shifts, recurring events, birthdays, and anniversaries. Tap any date to add notes, use voice input to convert speech to text, or long-press a day to quickly insert frequently used phrases such as “Morning Shift,” “Working from Home,” or “Day Off.”

Customize your view with light or dark themes, adjustable text sizes, row heights, week numbers, and Danish holiday visibility. Birthdays and anniversaries are highlighted in red, while other annual dates appear in grey. The app stores data locally on your device, collects no personal data, and supports FTP or plain-text file backups for easy data access and device transfers.
