Get the best out of this app …

⊛ … when using with your own DAV server (Radicale, DAViCal, SabreDAV, Baikal, …) and HTTPS – so you own and control all your data while having the comfort of synchronization between various devices. Or use a hosted DAV service you trust or the one of your company.
⊛ … and combine it with Evolution / Thunderbird / etc. on your computer

Why is it secure?

⊛ Source code is available (see homepage)
⊛ No need for giving your contacts/calendars to Facebook, Google, etc. Use your own server (or a trusted one)!
