GDPR General Data Protection Regulation

I am an entrepreneur from Germany and use your plugin.
Due to the EU general data protection regulation which comes into force in May I am writing to you today to get the following information.

1. Are you issuing an data/order processing contract?
2. What information of our website visitor do you store for what reason?
3. Will the data be transferred to a third country? If so, which ones?
4. What type or designation do you use for the level of data protection?
5. When do you delete this data?
6. Who is responsible for your data protection?

Thank you for your help.
Kind regards
Mirko Dahlke
