What Klender is
Klender is a shared calendar app for families and other groups, with web access and Android and iOS apps. Members can share calendar entries, view everyone’s activities at a glance, and associate appointments with individual family members. Shared practical lists can include groceries, birthdays, and address books. Appointment confirmation requests, phone notifications, and reminders help members track plans, and the family calendar can be printed for display at home. Klender can import or display appointments from other calendars, with one-way synchronization, and contacts can be imported from a device, Google, or Outlook. The service says it does not sell user data, build personal profiles from it, or use it commercially. It uses necessary technical cookies and Google Analytics cookies for anonymous statistics, but no tracking cookies. Deleted data is retained for six months for restoration; deleting an account permanently removes associated data immediately. Servers are located in Ireland. Klender offers a free plan, with ads appearing after three months and some features becoming unavailable. A paid contribution costs €2.99/mo per family, removes ads for all family members, and provides access to all functions.
