Incoming mail: my own server and my own domain (Postfix). Sufficient to receive confirmation mails and notifications.

Outgoing mail: no good/reliable solution yet. I have to send personal e-mail very very rarely.

Calendar: Tasks.org app, used offline (not synced).

Drive: 1TB external HDDs. GPG encrypted backups of important stuff are uploaded regularly to one of the VPSes I have.

VPN: Tor

Password manager: KeepassXC (with backups at 3 places).

Documents: Stored on computer, important ones are backed up. Confidential ones are stored on an encrypted LUKS volume which I only mount when I need something.

In general things I need on the go (e.g Calendar) is on my phone, the rest is at home at my computer. If I need to move data between devices I simply use USB drives. I don’t need no cloud sync of anything.

Proton’s probably the best mail.

Calendar: paper

Documents: cryptpad

As others have said no all-in-one solution, but Privacy Guides has good recommendations for each use case

What assurances do you have they won’t go full proton in the future?

Absolutely none. That applies to all services that exist now or in the future. The only way around that is self-hosting but that path has its own issues including a very steep learning curve if you want to be secure as well as private. Maybe this could be a longer term project to work towards?

For services:

• Mail - Mailbox.org seems the best option right now
• Calendar - don’t know.
• Drive - either Cryptomator used with literally any service or a dedicated service like Filen
• VPN - Mullvad
• Password Manager - Bitwarden
• Documents - I just use LibreOffice offline or CryptPad occasionally if I’m collabing with someone.

In truth none of these are perfect. Privacy has got a lot harder recently as Proton and StartMail/StartPage have politically shit the bed and the UK seems determined to kill encryption which means I have to avoid really good services like IceDrive just because they’re in the UK.

EDIT: Calendars. Mailbox.org’s included one works fine. You can sync using CalDAV. The process for Thunderbird (desktop) is here.

The process for mobile is a little more complicated. First you need Davx5 to actually get the data, but thats all that app does. It’s not a Calendar app. It does work with the native Android Calendar but I used FossifyCalendar.

So install both of those then login to your Mailbox account in a browser and create a Calendar (or use an existing one). Get its unique URL by looking under the heading ‘My Calendars’, clicking the three bars icon, click ‘Properties’ and you can then copy your CalDAV URL.

On your Android device open Davx5, tap the plus icon then specify ‘login with URL and username’ tap ‘continue’ then paste in the URL you copied earlier, your email address and your email account password, tap ‘login’ and that should work.

Now, switch to your Calendar app. I used Fossify Calendar so if you are too, open that up, go to Settings, scroll down to the CALDAV section and turn on CalDAV sync. It might switch to your new Mailbox calendar now, but if it doesn’t, tap ‘Manage synced calendars’ and activate it there.

Tuta is a great german alternative with e-mail and calendar. For Drive there is many options but I don’t feel recommanding one now For VPN there is Mullvad, IVPN and NymVPN(beta) For Password Manager there is BitWarden or any popular KeePass clients but sync is mainly on you. For Documents there is CryptPad

Custom domain + migadu.com

There are no viable package solutions, that’s the thing. If you want to make sure your service supplier shares your values, there’s nothing but self-hosting left.

ENTE for photo storage: https://ente.io/

Crypt.ee is also an option.

Have a look at: https://www.privacyguides.org/en/tools/

mailbox.org but i dont put all my eggs in one basket. I only mailbox for mail.

Tuta for mail & calendar, CryptPad for cloud docs and spreadsheets, Mullvad for VPN, plus a few other random things like Disroot which offers email and some other services. There’s some overlap and duplication but I don’t want to keep all my shit in one place any more. The Tuta app is blocky but acceptable. Everything else I only view in browsers.

Tuta – https://tuta.com/

Includes mail and calendar and contacts. No files, or password management. But worth a look, if you want an encrypted solution and you’re OK with using their client apps. I do, and I am and it’s great, IMO.

Their blogs say they’re pro-privacy, and anti-BS, if you believe them: https://tuta.com/blog

Mail and calendar I’m still trying to figure out. VPN you don’t need as long as you use HTTPS everywhere.

password manager

KeePassXC + KeePassDX

documents

Collabora Office + LibreOffice

What are the pros and cons relative to proton?

Pros: free, open source, and 100% offline with no intermediary company. Your file security is entirely in your own hands.

Cons: you must devise your own cross-device sync system. I use Syncthing + Syncthing-Fork.

What are the mobile apps like?

Collabora is currently just bad lol. It’s best reserved for really simple edits, if not just for viewing, with all major changes made on a desktop/laptop computer. KeePassDX isn’t terrible but it can’t view all the fields that the KeePassXC desktop platform can, and getting it to take PIN instead of password for vault-unlocking is really convoluted (although you’d only have to do it once).

What assurances do you have they won’t go full proton in the future?

They’re all open-source so anyone dissatisfied with the direction that the maintainers go in can fork them at any time.

Honestly you could easily selfhost all of that except mail and maybe a VPN.

Baikal for calendar. Vaultwarden for passwords.

disroot

Tuta will show you ads in your mailbox, don’t fall for it.
