GeneralSync

Your data is yours alone. Thanks to GeneralSync you can now keep it in sync across your devices automatically, without relying on a central infrastructure or the Internet: any synchronization is performed directly on your local area network (e.g. WLAN), we never get access to your data. A desktop application to sync with Mozilla Thunderbird and/or Microsoft Outlook is available on generalsync.com.

GeneralSync currently features the synchronization of address books and calendars between Android devices and PCs with Mozilla Thunderbird on all major platforms and Microsoft Outlook on Windows. More features are in development.

After pairing your devices, GeneralSync will automatically keep your content up-to-date while at least two devices are connected to the same network. As your data never leaves your network, our servers are not involved in the process and cannot access your data at any time. Of course, the transfer is nevertheless encrypted end-to-end, in order to also protect your data against local attacks.

All data is stored on all devices, thus permitting offline use at any time. If a conflict should happen, for example after different changes have been made on multiple devices, you will be notified and can individually select the correct version.

A particularly useful detail is GeneralSync's ability to use multiple networks: by carrying your smartphone or other portable devices with you, you enable full synchronization across networks, without trusting a third party with your data.

Besides regular synchronization, GeneralSync is capable of sharing data read-only. It is possible to further restrict devices, for example to only share the time and availability of your events, without any details. Please note that on Android, some third-party Applications do not properly support read-only address books and display controls to edit their contents, any change you perform on a read-only address book will be reset by GeneralSync and not get synced in any way.
