Everything included
Your workspace in your pocket
The same tools as in the browser – as a native app that blends into Android and works offline.
A full-featured, native email client based on the modern JMAP standard – right in the app, no extra program needed: inbox, sent, drafts and trash, compose with attachments, signature, replies and search. Sync only transfers changes – fast and data-efficient.
Link – chat & calls
Souvera Link right in the app: team chats and direct messages, plus audio and video calls – connected to your own workspace.
Files
Access your entire file storage: upload and download, share, make available offline and search.
Calendar
View and edit events, all-day entries and reminders – in sync with the Android calendar.
Contacts
Your central address book right in the app and in Android contacts – always up to date across devices.
Notes
Create, edit and delete notes – automatically synced with your workspace.
Photo upload
Automatic upload of new photos and videos into your file storage – your memories safely stored in Germany.
Push notifications
New emails show up on your device instantly – via JMAP push, triggered by your own mail server through the Souvera push pipeline.
Technology
Email via JMAP – this is how fast mailbox sync feels
The app's mail client talks to your mail server via JMAP (RFC 8620) – the modern email standard replacing IMAP and SMTP. That makes email on your smartphone noticeably faster, more efficient and more secure.
Push instead of polling
The server initiates new emails directly – the app no longer polls. That saves battery and mobile data.
Only changes are transferred
JMAP syncs incrementally: only what changed is transferred – folders open in milliseconds, even with a full mailbox.
Search on the server
Full-text search runs server-side across your entire mailbox – find any message without having downloaded it.
Secure by default
HTTPS only, with token-based authentication – passwords are never transmitted in plain text.
In action
A look inside the app
A clean, calm interface in the Souvera design – light and dark.
Safely connected – even behind the wheel
Souvera Link is integrated with Android Auto: answer and end incoming calls right from the car display or the steering-wheel buttons. Your car reads out new chat messages, and you reply by voice – hands on the wheel, eyes on the road.
Calls through your car
Link calls ring in the vehicle – answer and hang up via the display or steering wheel, with audio over the hands-free system.
Messages read aloud
New chat messages are read out while you drive – without a glance at your phone.
Reply by voice
Just speak your reply – Souvera Link sends it straight into the conversation.

Calendar in the system calendar
Events sync bidirectionally into the Android calendar provider – including recurring events, all-day entries and reminders.
Contacts in your address book
Your address book is two-way synced with Android contacts – local changes flow back to the workspace.
Automatic background sync
Native sync adapters keep everything current – new events and contacts appear on the device without lifting a finger.
