How our Android sync works

CompanionLink is software that installs on your PC. Our DejaOffice app (free on the Google Play Store) installs on your Android phone or tablet. Both products work together to create a direct and secure connection between PC and device. You can choose from USB or WiFi sync - both methods keep data local between your PC and device. Another option is DejaCloud sync for those who prefer the convenience of cloud integration with multiple devices (like a phone and iPad or other tablet).

Our software works with: Microsoft Outlook, Act!, Palm Desktop, Lotus Notes, GroupWise, GoldMine, Time & Chaos, and Salesforce CRM.

More about DejaOffice: DejaOffice is our Android app that stores your PC data in an encrypted account on your Android. Your data is never sent to Google or other cloud-connected accounts unless you choose to allow this by integrating with the device's built-in Contacts and Calendar apps. The app works similar to common PC apps like Outlook and Palm Desktop with modules for Contacts, Calendar, Tasks, and Notes. With thousands of reviews and a 4-star rating, we're confident you will like the productivity and data security this app gives you. You can take a visual tour of the app here.

"I tried other sync products to sync my Droid with Outlook. This is by far the BEST, EASIEST to use."
