1. I deliver only the best quality of work and do revises (if any) until you are satisfied. If eventually, you cannot use my work either you find it not usefull for you, and I'll send your money back.
2. You are free to ask for revision and report any error or descrepancies found in the future and I will fix it for FREE as long as it's in the scope of the initial project's description and our discussion during development.
