  • Best way to have Calendar, Contacts, emails synchronized with PC?

Hi i am researching GrapheneOS and Calyx and would really like to get away from google. One big hinderance for me is that i have used Outlook for calendar and contacts and i must say the calendar Optoins with recurring events are just fantastic.

To not give my data out in the cloud with calendar, contacts i used: akruto Sync. The software emulates an Windows Exchange Server to keep Contacts and Calendar the Pc in Sync with the phone without giving your data in the cloud.

An additonal plus was that the emails where in Outlook too, but most important was the contacts and the calendar.

What would be good solution to get as close as possible on Graphene?

    SpeakYourMind you can use Outlook as a Web App installed via Vanadiums (browser) menu. However notifications may be an issue.

    SimpleMobileTools Calendar which is a FOSS AOSP Calendar replacement alternative offers CalDAV sync.

    Tutanota offers similar functionality to Outlook as far as email, calendar and contacts, and also offers Calendar import via .ics.

      I run radicale on my server and sync calendar and contacts with my phone using DAVx5. On my desktop I use Thunderbird which supports DAV as well.

      thanks for the Input so far. I am not an overly technical person and i rather have something without my own server.
      The akruto Sync version just used my computer at home as the "server". When i come home the phone connects over WIFI with the Computer and synchronizes calendar and contacts from the locally running Outlook. So i don't want to use outlook.com. Tutanota has fans - i know - but i don't trust them.

      So is there something similar to this approach the laptop is the server which is not to error prone?
      Or do i have to set up owncloud or something.
      Again, i am willing to move away from Outlook i just like the repeat feauters and alarms.
      The CalDAV sounds interesting i need to watch some videos/read up on this.

      Have a good one!

        EteSync for calendar + contacts sync, Etar for calendar display/edit/alerts. K9-Mail for emails. If you use external/shared calendars davx5

        From how you describe yourself, I can strongly recommend Nitrokey's Nextbox. It is a little computer with storage that comes with Nextcloud pre-installed (imo Nextcloud is the better Owncloud :) ). You would basically host your own Nextcloud server, but without needing any technical skills. After you did the initial setup, the Nextbox is just plugged into your router and a socket. Even updates of Nextcloud are really easy!

        The amazing thing: you can then use all Nextcloud apps (very easy to install)! You can then eaaaasily sync contacts, calenders and whatnot between laptops and phones via the Nextbox! So cool! You could even setup accounts for family members on your Nextbox.

        On my GOS phone then I use DAVx5 to do the syncing and Etar as a calendar app. On laptop, Thunderbird works well. With this setup, there is only FOSS involved and you have a carefree "server" even on-premise. :) Feel free to ask further questions.

          SpeakYourMind Tutanota has fans - i know - but i don't trust them.

          mailbox.org is often recommended and has very good reputation. You can pay in cash and don't have to state real names or physical addresses. You could also sync calender and contacts via the server space included in the cheapest accounts they offer.

              Migrate your data to Proton [https://proton.me] and stop using Outlook is one option.

              Calendar - Proton Calendar app
              Email - Proton Mail app
              Contacts - my solution is split:
              (a) All contact details including high value contact information (eg: DOB, address, email) are stored in the contacts section of the Proton Mail app. The contacts are in the cloud so no synching required.
              (b) Basic contact information (eg: name, phone number) is in the AOSP stock contacts app. Not synched. Export and back up the csv file periodically to PC.
              All PC based activity is via a web browser logged into Proton for contacts, email and calendar. Contacts within Proton Mail contacts will become available within the Proton Mail app, cloud calendar will sync with the Proton Calendar app.

              High value contact information is enclosed in the Proton Mail app and not subject to Android contact permissions.
              The calendar information is enclosed in the Proton Calendar app and not subject to Android calendar permissions.

                I don't see how this relates to anything I wrote but ok. It's not like my sentence "You can pay in cash" somehow implies "they cannot get your IP" or "you are anonymous go do crazy shit". Also, trivial to use Tor, problem solved.

                I use Calendar from Simple Mobile Tools. When I try to turn on CalDAV sync, I get "No syncable calendars have been found." I read from the DAVx5 documentation that calendar apps can sync their data to Android Calendar Storage (preinstalled app without GUI).
                Have any of you solved the same problem? Do I understand correctly that GOS does not include the Android Calendar Storage app? Is it possible to install it?

                  @fromTom Did you figure out the issue you were having with no calendars found error? I am having the same issue. Maybe storage pools needs to be adjusted?

                  fromTom Android Calendar Storage is not a CALDAV Server. It is a local container. You will need to set up a CALDAV Server via an external source connected to your local calendar storage via DAVX5.
                  External sources include: Nextcloud, Baikal, Ete-Sync, Posteo.de, Mailbox.org, and Google if you want to go down that path. I posted on this subject a few days ago.

                  I've been using Protonmail for EMail, and Etesync for CalDav and CardDav Calendar, Contacts and Tasks sync across platforms for the last four years or so with great success. I use the Etar app from F-Droid and Thunderbird on desktop with the Lightning and Cardbook add-ons to sync my calendar and contacts, though TB just recently added native support for CardDav I believe. I find both Protonmail and Etesync with the Bridge program and the Android apps is an incredibly easy, open source and encrypted way to keep your contacts and calendar access. The Protonmail Android app is a little to be left desired due to no push notifications or auto-updating APK now going on four years later for some reason.

                  If you are wedded to Outlook like some of us are with our jobs, you can use the DavMail bridge client to access the Exchange Server on desktop PCs with just about any email program you like, including Thunderbird. For Android access, you can set up a DavMail server (very complicated) to access your Exchange Server with K-9 Mail, FairEmail, and Davx5. On Outlook, you can access your Etesync calendar and contacts with the CalDav Synchronizer program. I have not gotten around to setting up the DavMajl server so I am using Nine Folders from the Play Store to access my work calendar emails and tasks, which uses Office365 sadly.

                  Hi @sycamore,
                  thanks for your recommendation of Nitrokey's Nextbox!
                  But I have no landline, therefore I have no router for (A)DSL.
                  I have only mobile-telephony (unlimited plan), using my smartphones as WLAN hotspots.

                  Is it possible to get this nice Nextbox online via tethering, using a smartphone or LTE USB-dongle?
                  I couldn't find anything about this in the online docs/website of Nitrokey.
                  But maybe you can find it in their manual or know a newer link to that information with all ways to go online with that Nextbox?
