SilentSuite - Secure Data Sync
End-to-end encrypted sync for calendar, contacts, and tasks
新版本 0.5.16-beta
Requires Android 10 or newer. Preserves birthdays without a year and safe extra contact text fields. Adds offline Unsynced Notes recovery and sign-out safeguards. The task-app reminder can be dismissed. Saving a collection after a failed delete no longer deletes it.
Your calendar, contacts, and tasks should stay in sync wherever you work: Android, macOS, Windows, Linux, and the web. SilentSuite keeps that data available across your devices while applying end-to-end encryption before anything leaves your device.
Zero-Knowledge Sync
Encryption and decryption happen on your device, and your keys stay there. The server stores only ciphertext, so it cannot read what you keep on it. This is what zero-knowledge means in practice: the privacy guarantee is a technical constraint, not a policy statement.
Fits Into Every System You Use
On Android, SilentSuite works as a native sync adapter for compatible calendar, contacts, and task apps. On macOS, Windows, and Linux it integrates through a lightweight desktop bridge, so your encrypted data can appear in the tools already built into your workflow. The web app gives you browser access when you are away from your own devices. iPhone support is coming soon.
Open Source And Inspectable
Anyone can read the code, review the encryption, and confirm the privacy claims for themselves. There are no proprietary components to take on trust.
Hosted Or Self-Hosted
Use the hosted service, or run your own server on hardware you control. Your data stays portable: export it at any time in standard formats, with no lock-in.
Beta Note
This is a beta release. Calendar, contacts, and task sync are the focus of this version and form its stable core. Feedback and bug reports are welcome through the link in the app.
What You Need
Requires a SilentSuite account. Self-hosting documentation is available at docs.silentsuite.io.
