Frequently asked questions
Is it really free?
Yes. There is no sign-up and no email address needed. Just download the file. If it helps you, you can buy me a coffee, but that is entirely optional and does not unlock anything.
Where do I find views and sales?
Most platforms show views and sales for a chosen date range in their shop statistics. Use the same number of days before and after the change.
Why does it say not enough data?
With only a few views or sales, results swing by chance. The log waits for at least 200 views and 5 sales across both periods before giving a verdict.
