FAQ
- Is it free?
- Yes — the profit calculator and research signals are free. A Pro tier (saved products, CSV export, more marketplaces) is coming later.
- Does it collect my data?
- No. SellerScope makes no network calls and sends nothing to any server. Your inputs stay in your browser. See the privacy policy.
- Are the fees and sales numbers exact?
- Fee %s are editable estimates — set them to your exact category. The sales estimate is a directional guide from Best Sellers Rank, not an exact figure.
