DAVsky – Calendar Sync & Feeds

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 • Every address book shows up as its own account in your contacts app EVERYTHING AT A GLANCE • Every account as a tile: how many calendars, address books and task lists are active, when it last synced and when the next sync is due • Sync log per calendar and address book: what was downloaded and what was uploaded, split into events, tasks and contacts – runs without changes are grouped • Clear notices instead of silent failures: problems show on the account, and if background sync stops running, DAVsky points you to the right setting on your device • Export calendars as .ics and address books as .vcf 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, even copied straight from the browser's address bar; 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 • Quiet hours: no background sync at night or at times you choose • 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 and shows no ads. No data is shared with third parties: calendar, contact and task content is processed on the device and exchanged only with your server – not through us. DAVsky is built on open standards (CalDAV, CardDAV, iCalendar, vCard). You stay in charge of your data and your servers.
