Calendar & contacts: replace Google Calendar
8 private options, our pick first. Every download link goes straight to the source — F-Droid, the developer's GitHub releases (one tap into Obtainium), the Play listing you can install anonymously through Aurora Store, or the official site. None of these are affiliate links. Updated October 2026.
These Google Calendar alternatives keep your schedule and address book on Android without a Google account. Proton Calendar sits next to Proton Mail with encryption. The open route uses DAVx⁵ to sync any CalDAV and CardDAV server into Etar, Fossify Calendar and Fossify Contacts.
The trade-off is that Google bundles calendar, contacts and invites for free. A private setup in 2026 asks you to pick a provider and connect two or three apps once. After that it runs quietly. It can replace both apps, and holiday or school feeds work through ICSx⁵.

How to switch from Google Calendar
- Export your calendars and contacts. In Google Takeout, Calendar arrives as .ics files and Contacts as vCard .vcf files. Proton users can also use Easy Switch to import straight from a Google account.
- Set up the new account. With Proton, install Proton Calendar and sign in. With Nextcloud or another CalDAV provider, install DAVx⁵, add the server, and choose which calendars and address books to sync.
- Import the .ics files into the new calendar and the .vcf file into the new contacts app or server. Then check recurring events and time zones on a few dates.
- Set your new calendar and contacts apps as the defaults, and add ICSx⁵ subscriptions for the school, sports or holiday calendars you used to follow in Google.
- Ask people who share calendars with you to share them again with your new address, or to send invites there. Shared Google calendars don't move by themselves.
- Remove the Google account from the phone's calendar and contacts sync last, only after events and phone numbers show up correctly in every app you use.
Calendar & contacts questions
Will I still get meeting invites from Google Calendar users?
Yes. Calendar invites are standard email attachments, so invites from Google Calendar users arrive in any inbox and can be added to Proton Calendar or a CalDAV calendar. Replies go back by email too. What you lose is Google's habit of adding invites to your calendar automatically before you have even looked at them.
Why do I need DAVx⁵ at all?
Android has built-in storage for calendars and contacts, but no built-in way to sync them with a non-Google server. DAVx⁵ fills that gap. It syncs CalDAV and CardDAV accounts into the system, so any calendar or contacts app on the phone can use them. It is free on F-Droid and paid on Google Play.
Can I subscribe to a public calendar without Google?
Yes. ICSx⁵ subscribes to any .ics link, such as a school timetable, a sports fixture list or public holidays, and refreshes it on a schedule you set. The events show up in your normal calendar app next to your own. These subscriptions are read-only, which suits feeds you follow rather than edit.
