Sister is


An important principle to us is complete financial disclosure. This way we show and clarify...


- ... costs for traveling, accommodation and meals are paid by ourselves.


- ... donations are on an extra bank account.


- ... all expenses are documented and listed in the report .


- ... non-negotiable costs are paid by the travelers


 - ...some money is available for spontaneous donations – in agreement with the sponsors.


- ... most transparency is achieved by taking decisions always together.


- ... after every journey there is made a report with all projects – starting with the estimation of cost to the completion.

      The report is published on the homepage and it is possible to request a printed version as well
