Editor's Overview

DecSync CC is a cloud storage & file sync application developed by Aldo Gunsing, packaged as a single Android APK of version 2.2 weighing in at 7.3 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

  1. Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
  2. File size is a light 7.3 MB, so it installs quickly even on modest connections.
  3. This build is signed by "Aldo Gunsing" — always verify the developer name matches what's listed on the app's official store page before installing an update.
  4. After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
  5. We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

DecSync CC synchronizes contacts, calendars and tasks using DecSync. It stores this data in a shared directory, using Syncthing, Google Drive, Dropbox or any other file synchronization service.

Syncthing synchronizes files directly between devices, without storing the data centrally or requiring a server. DecSync CC works with any file synchronization service, but using Syncthing is recommended as your data stays on your devices.

The UI is based on the one used in DAVx⁵.

Frequently Asked Questions

Is DecSync CC free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does DecSync CC require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is DecSync CC safe to install?
We link to the exact APK published by Aldo Gunsing. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update DecSync CC?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
