DAVsky – CalDAV CardDAV ICS

About this app

DAVsky keeps your device's calendars, contacts and tasks in sync with your own CalDAV/CardDAV server – open, standards-based and without routing your data through anyone else's cloud. Your data travels straight between the device and the server you choose.

WHAT DAVSKY DOES

• Sync calendars (CalDAV), contacts (CardDAV) and tasks in one app
• Tasks need a task app such as OpenTasks – Android has no built-in storage for them
• Subscribe to ICS/webcal feeds, such as holidays or team schedules
• Manage several accounts at once – DAV servers and feed subscriptions side by side
• Two-way sync: changes on the device reach the server and the other way round

EASY SETUP

For many providers DAVsky guides you step by step – including Nextcloud/ownCloud, mailbox.org, Posteo, Fastmail, SOGo, Baïkal, Radicale and iCloud. For anything else, just enter the server address; DAVsky finds the paths itself.

YOU STAY IN CONTROL

• Separate sync interval for calendars, contacts and tasks – from "manual only" to daily, or a value of your own
• Sync over Wi-Fi only to save mobile data
• Trust self-signed servers deliberately, with the fingerprint shown
• Sync every account with one tap – button, launcher shortcut or home-screen widget
• Light and dark themes that follow the system setting

FAIR AND OPEN

DAVsky is free, shows no ads and contains no trackers. It collects no usage data. Calendar, contact and task content is processed on the device and exchanged only with your server – not through us and not with third parties.

DAVsky is built on open standards (CalDAV, CardDAV, iCalendar, vCard). You stay in charge of your data and your servers.
