Straight answers
Before you buy
What exactly do I get?
An instant digital download: the file(s) listed on each product page. Nothing physical is shipped. Each product page lists what is inside.
How do I pay and receive my files?
Pay with PayPal (or a card through PayPal's checkout where offered) and we email a private download link to your PayPal email, usually within about 15 minutes. Or pay with Bitcoin: send the exact amount shown and email your order code to eclipsekingdom.support@gmail.com; we send your link after one blockchain confirmation. Links work for 30 days.
What if it doesn't work for me?
Email eclipsekingdom.support@gmail.com within 30 days and we'll fix it or refund you. See terms & refunds.
Are the fee numbers up to date?
Defaults are examples dated inside each file and tool (for example Etsy US fees checked 2026-11-14). Platforms change fees, so every rate is an editable input: always use your own current rates.
Is this financial, tax or legal advice?
No. These are general planning tools. For decisions specific to you, talk to a qualified professional.
