I have purchased a SimpleSYN Lifetime License Version 1. Can I also use the current version 2 with this license?

SimpleSYN Mobile Lifetime licenses in version 1 are unfortunately not valid for the main version 2.

With a lifetime license, you will not incur any additional costs per month/year. The license entitles you to use the licensed version (e.g. version 1.0) indefinitely. Minor updates (eg version 1.0 to version 1.0.1 etc.) are included. Major upgrades to new versions (eg version 1.x to version 2) are subject to a fee, but optional.

Subscription include upgrades to new main versions in addition to minor updates.

If you are interested in version 2, you can also test the new main version free of charge for 30 days.

SimpleSYN requires an active internet connection for its operation. The internet connection is required to connect to a central server operated by SimpleSYN. This server is used to help in the establishment of a direct connection between the SimpleSYN server and SimpleSYN client. Only data required for establishing the connection is transferred via this central server. After establishing an connection, SimpleSYN uses the best connectivity available.

If SimpleSYN Business is used to synchronize via the Internet and it is impossible to create a direct connection between SimpleSYN server and SimpleSYN client, e.g. because of Firewalls NAT or Routers are blocking the direct connection, SimpleSYN uses a relay server as a last resort. This relay server allows SimpleSYN to communicate even if only outgoing traffic is allowed from your networks.

In either case the connection between SimpleSYN will always  use an SSL/TLS encryption respectively.

Your Outlook data is never transferred in clear-text nor stored permanently on our Internet servers (no Cloud).
