I'm sorry to announce that after 18 years online, Beermad will be closing down later this year. Please see the announcement and explanation page for more details.
This app does not (and cannot) communicate in any way with any device other than your own. The only files it reads or writes are its own database file and files that you opt to import or export beers from.
When you contact me using the "email developer" option, the app includes in the email details of the type of device you are using along with information about its screen resolution, as well as details of your app's saved settings. This is to help me diagnose any problem you may be reporting, as there are a huge number of configuration combinations and a bug you encounter may be unique to your setup. All of the information which is sent is visible to you as you compose your email.
