Do I already need to know a lot of astrology?
Nope! You can use your natal chart with it if you know your chart positions, but if you don't, you can just follow the prompts and read your Sun sign scopes as-is.
How long do I have access?
The PDF files are downloadable, so you have access for however long you have them!
What format are the files delivered in?
It's entirely PDF files (so you do need free Adobe Reader or Google Drive to view them; most computers and smart phones already come equipped to view them).
What currency do you use?
US Dollars, and you can pay with a credit card or Paypal.
