Postcards sent to LOSST are kept and cherished. Return mailing addresses are kept in our rolodex if requested. Mailing addresses are never shared or used for other purposes except to send you art.
If you make a purchase through our online store we keep the information you provide us in the same rolodex and use it to send you the art you purchased.
In both cases, if requested we'll also keep your contact information to send infrequent mailings about whatever it is we're up to over here.
