Fossify Calendar
What Fossify Calendar is
Fossify Calendar is a free Android app for managing events, reminders, and routines. It offers day, week, month, year, and event-list views, with recurring events, holidays, celebrations, and reminders. Calendar data can be imported and exported, and notes can be shared. Custom home-screen widgets and color, theme, and display controls change the presentation. Two-way synchronization works through accounts or calendar providers configured on the Android device; Fossify does not run a calendar sync service. The app works offline and does not require a Fossify account or cloud service. It requests no Android Internet permission, contains no advertising, does not track users, and sends no app data or usage records to Fossify. It uses calendar events and account information and may access contacts for birthdays, anniversaries, or participants. The source code is public, with downloads linked through Google Play and F-Droid.

Verdict
