aCalendar only asks for mandatory permissions for its functionality. No data of yours will ever be shared with anyone unless you decide to. We have no access to any of your data. If you have any questions about permissions please contact our support by email.
Unfortunately app2SD cannot be supported, because homescreen widgets do not work from SD. This is an Android limitation. But aCalendar is optimized not only for speed but also for size.
aCalendar is made with love, sweat and tears in the heart of Munich. If you like aCalendar, please rate or comment and recommend it to your friends. Also consider upgrading to aCalendar+ for extra features
