Kalender.digital is a German online shared-calendar SaaS for individuals, families, teams, companies, clinics, associations, schools, and similar use cases. Its core design is “use the calendar via access links”: users can view, edit, or manage schedules without registering or logging in, making it well suited to low-friction sharing and ad hoc collaboration.
The product supports sub-calendar categories, color coding, printing/PDF, statistics, import/export, public holiday/vacation imports, website embedding, auto-refreshing information screens, and booking functionality. The booking module can automatically offer available time slots based on existing free time, and you can specify which sub-calendars should be included when checking availability.
For collaboration, each calendar can generate access links for admins, editors, readers, and other roles, with read/write permissions configurable per link. Permissions can also be refined at the sub-calendar level. Plus and above support password protection for access links and custom links, while Premium further adds attachments, Excel export, SMS reminders, invitations/registration, white labeling, custom logos, and an API.
Pricing is fairly transparent: Basis is permanently free and includes 6 sub-calendars, 3 access links, unlimited users, and 1 booking link; Plus costs €6.90/calendar/month, or €5.52/month with annual billing; Premium costs €14.90/calendar/month, or €11.92/month with annual billing.
Third-party integrations are mainly based on iCalendar/ICS. Calendars can be imported from Outlook, Google Calendar, and Apple Calendar, and exported to external calendars. However, synchronization depends on the refresh intervals of third-party calendar imports, so it is not full two-way real-time sync.
The website states that it is GDPR-compliant, with servers located in Germany. IP addresses are stored only in anonymized form, and data is not sold or passed on to third parties. Access links are 20-character random hexadecimal strings and can be further protected with passwords. Unauthorized access attempts are logged and IPs can be blocked.
The available text does not mention SSO, audit logs, an SLA, or enterprise compliance certifications.
Its strengths are ease of use, no-account access, a usable free plan, and a flexible permission model. It is especially suitable for associations, clinic scheduling, team calendars, room planning, vacation schedules, and website calendar displays.
Its limitations are that advanced capabilities are concentrated in Premium, enterprise-grade identity governance details are limited, and there is no clear information about a Chinese interface or local support.
The crawled text does not provide information about network connectivity from mainland China, payment methods, or RMB billing, so its accessibility from China is currently unknown. For domestic teams in China, alternatives to compare include Feishu Calendar, WeCom Calendar, and DingTalk Calendar. If you need international booking and calendar ecosystem support, Google Calendar, Outlook Calendar, Teamup, or Calendly may be worth considering.
