In general support people have access to all your info, and developpers have access to your data for troubleshooting. Except if they do a really good job at making so no loopholes exist, but it's the exception more than the rule, and it takes time an effort for a result that is not self evident to the customer and causes heavier frustrations when there are bugs in the app. Now, in small to middle companies most of the time support people = developper, so you shouldn't think of your data to be unreadable inside the company thay handles it, except if advertised otherwise and you trust their words.
