FAQ
Is this an official marketplace app?
No. It is an independent calculator and is not affiliated with those companies.
Are the fee rates up to date?
We show the last-checked date and source URL. Rates can change—verify on the official site before listing. In the app you can edit rates.
Web vs app?
The web tool covers one-sale take-home, reverse price, and default fees. Saving, multi-market compare, multi-line materials, CSV, and offline use are app-only.
Where is data stored?
The app stores data on-device only. The web tool does not save or send inputs.
What does it cost?
A one-time unlock is planned, but pricing is not published here until store setup is approved.
