When you install aCalendar, Android will ask you to grant certain permissions. Here is what each permission is for – and why it is needed.
We respect your privacy and will never share your data.
Calendar Read & Write
aCalendar needs to read and save your calendar data. The app itself stores nothing – all your calendar entries (local and cloud) are kept in Android’s own calendar storage. Without this permission, the app cannot work at all.
You will be asked to grant this permission when you first open the app.
Contacts Read & Write
This permission is needed for the following features:
- Birthdays & anniversaries from your contacts
- Linking an event to a contact
- Inviting attendees to an event
- Using a contact’s address as an event location
Storage Read & Write · Android 10 and below
This permission is used for file attachments on events. It is only requested when you use attachments for the first time – not on install.
Note: On Android 11 and above, this permission is no longer needed.
Notifications Android 13 and above
Starting with Android 13, apps must explicitly ask for permission to send notifications. We strongly recommend granting this – otherwise you won’t receive any event reminders.
All notification types can be individually configured in the notification settings.
