How does the eBay connection work?
You sign in and approve access on eBay’s own consent screen. NVCARIA uses that connection to import your finance activity. Review the requested permissions before continuing. You can disconnect in NVCARIA or revoke permission through third-party app access in your eBay account settings.
Does the dashboard include my item costs?
Imported finance activity does not include your inventory purchase costs. Add item cost and other expenses in the calculator to estimate profit.
Can I disconnect my eBay account?
Yes. Disconnecting in NVCARIA stops future imports and clears the saved connection credentials. Your imported history stays in your workspace. To revoke NVCARIA’s permission on eBay too, remove it from your eBay third-party app settings.
Can I cancel anytime?
Yes. You can cancel a subscription at any time from your account billing settings. Access continues through the end of the current billing period.
