There are plenty of hints and messages, which would bust this documentation. For further questions, write a mail! 
For correct operation of SecretSheep, please be sure that show caller ID is set in your phone-settings! SecretSheep uses the selected hide-prefix if it is required to hide your ID. Otherwise the call is just forwarded and the phone-settings is used.
Looking forward getting your feedback. Write about new prefixes, bugs (in the software – I am vegetarian), improve­ment suggestions, tasty types of coffee beans, coordinates of lush meadows (near Austria), etc. to nerdy (at)

Enjoy calling with this app! ;-)
