FAQ
The essentials.
Why would anyone send €1?
There is no promised personal benefit. The decision itself is the subject of the experiment.
What happens to the money?
It remains with the project operator identified in the Legal Notice and has no predetermined use.
Is this a donation?
No. It is not a tax deductible charitable donation and no charitable organization is represented.

What data is retained, and will results be public?
Campaign totals and limited technical payment references are retained. The project does not receive recipient lists or create personal browsing profiles. Aggregate results are intended for publication. Privacy details.
