Fossify Calendar

Fossify Calendar is an open source calendar app for managing events and schedules without ads, tracking, or intrusive permissions. It keeps events private while giving you a place to plan daily life, work, and family dates.

Events can carry times, durations, reminders, and advanced repetition rules, and event filters narrow down what you see. Views include daily, weekly, monthly, yearly, and event layouts, with custom sounds, vibrations, themes, and home screen widgets. Holidays and special dates can be imported so birthdays and anniversaries are not missed.

Fossify Calendar syncs with Google Calendar, Outlook, Nextcloud, Exchange, and more. It is one of the Fossify apps and runs entirely on the device rather than through a hosted account.
