LearnPress Support Facility after purchasing

Hi,

I am planning to purchase the LearnPress plugin but before that I wanted to clarify few business requirement support. Below are the points:

1. Post-launch support: Do LearnPress provide the support in terms of functionality or any bug in the product?
2. Industry spread / popularity: How strongly its been used by the customer or is it used by any known good organization?
3. Data migration capability: Do LearnPress provide the facility to do the Data migration?
4. Open issues / Vulnerability measure: How correct the product is or still the issues are being fixed?
5. 3rd party integration.: 3rd party API integration is possible or not?
6. Custom DB setup: Can we store the data or any sensitive information in secured DB not in the WP default DB?
7. Styling control.: Do LearnPress Provide the Styling control once after purchasing the product? How can we control the design from the Admins site more like GUI?
8. Admin capabilities.: What are the user levels available in LearPress?
9. Security concern: How LearnPress provide the security to the code, DB, or malware attack to the plugin?
