SilentSuite for Android

SilentSuite has its own Android app for end-to-end encrypted sync of your calendar, contacts, and tasks. It's a maintained fork of the EteSync Android app, pre-configured to work with SilentSuite.

What You Get

Once set up, your SilentSuite data syncs directly into Android's system calendar, contacts, and task providers. This means any calendar app (Etar, Simple Calendar, etc.) and any contacts app will show your encrypted SilentSuite data.

Install

Choose one of the install options below. Both deliver the same APK from the same GitHub release.

Option 1: Obtainium (recommended)

Obtainium is an open-source Android app that installs and auto-updates apps directly from their GitHub releases -- no Google Play, no tracking, no account needed.

1. Install Obtainium from GitHub Releases or F-Droid.
2. In Obtainium, tap Add App and paste this URL:

   https://github.com/silent-suite/silentsuite

3. Obtainium will detect the latest SilentSuite release and install the APK. It will notify you whenever a new release is published.

Option 2: Direct APK download

Grab the latest APK directly from GitHub Releases:

• github.com/silent-suite/silentsuite/releases/latest

Look for the asset named silentsuite-android-vX.Y.Z-beta.apk and install it. You'll need to allow installation from unknown sources the first time.

TIP

The SilentSuite Android app is a fork of the EteSync Android app with SilentSuite branding and server.silentsuite.io pre-configured as the default server. If you prefer, the original EteSync app from Google Play or F-Droid also works -- just enter the SilentSuite server URL manually.

Set Up

1. Open the SilentSuite app.
2. Tap the + button to add an account.
3. The server URL is pre-configured to https://server.silentsuite.io. For self-hosted instances, tap Advanced Settings and enter your server URL (e.g. https://sync.your-domain.com).
4. Enter your username (email) and password.
5. Tap Log in.

The app will sync your collections. Your calendars, contacts, and tasks now appear in your Android apps.

Choosing a Calendar App

The SilentSuite app is a sync adapter -- it syncs data in the background but doesn't have a built-in calendar UI. Use any Android calendar app:

• Etar (open source, F-Droid) -- lightweight, recommended.
• Simple Calendar (open source, F-Droid) -- minimal and private.
• Google Calendar -- works, but sends event metadata to Google for notifications. Not recommended if privacy is a priority.

Choosing a Task App

For tasks, use:

• Tasks.org -- has built-in EteSync/Etebase support and can also read from the Android task provider.
• OpenTasks -- reads tasks from the Android task provider populated by SilentSuite.

Source Code

The SilentSuite Android app is open source. The source lives in the android/ directory of the main monorepo:

• github.com/silent-suite/silentsuite/tree/main/android

Troubleshooting

Data not syncing

Open the SilentSuite app and check the sync status. Pull down to force a sync. Check that your account shows as connected.

Calendar not showing in my app

Some calendar apps need you to enable the SilentSuite calendar in their settings. Look for a "Calendars" or "Accounts" section and make sure the SilentSuite calendars are ticked.

Battery optimization

Android may restrict background sync. Go to Settings > Apps > SilentSuite > Battery and select Unrestricted to ensure reliable sync.
