Your name, email address and postal address will only be used for allowing the author to give you a free copy of the novel O-Vega-K or to post it to you.
The data will not be shared with any third party, and will not be stored on any database.
Prior receipts of donations are required as proof that the copies are not being sold, as it is illegal to sell books that do not have an ISBN number. They do not represent distrust on the part of the author.
