SignRequest uses Amazon's data center in Dublin (Ireland) which is part of the European Union for our data storage. As an additional back-up we use Amazon's data center in Frankfurt (Germany). Your contracts will not be stored outside of the EU.
In some cases our customers do not want that any data is saved on our servers. In that case it's possible to automatically delete the data from our servers using the SignRequest API after it has been saved on your own system.
