Unfortunately no refund policy... but the database is old, rubbish and scam because it's not up to date. Some Links are marked as "DoFollow" but are "NoFollow" meanwhile or public backlinks are unpublic in the meanwhile. The database and a lot of "backlinks" are not up-to-date and for this price it's not acceptable. So only one Taco because of the low value for this price. I used lot of AppSumo Software very valuable but this one isn't.
