Before you decide
A few useful boundaries.
Is this Excel, a mobile app or a cloud service?
No. These are downloadable HTML tools for modern desktop browsers with JavaScript. Safari, Firefox and native phone file viewers have not been verified. Use an actual browser rather than a document-preview app.
Where is my information stored?
The paid tools attempt to save data locally in your browser. Storage may be unavailable for local files and can be erased by private browsing or clearing browser data. Download JSON backups. There is no account, cloud sync or automatic cross-device sharing in the downloaded tools. This demo uses temporary sample inputs in page memory and does not send them to a calculation service.
Will the tool guarantee a profitable selling price?
No. Calculations depend on your inputs. Include actual costs and fees; tax, returns and omitted costs can change the result. These are planning worksheets, not accounting, tax or financial advice.
What usage rights do I receive?
Use the purchased tool for your own personal work or one business, and keep private backups. You may use its resulting reports in your work. Do not redistribute or resell the source files.
What about support and refunds?
Contact the seller through the Gumroad purchase receipt for file or calculation issues. No response-time promise is included. Review the refund terms shown on the Gumroad product page and checkout before paying.
