TicketStars eBay Pricing is a private, internal inventory-and-pricing tool built for a single eBay seller account (trendtreasures22). It is not a public app and does not offer any service to third parties.
When authorized, it reads that seller's own eBay listing, order, and price data via official eBay APIs, solely to analyse and recommend prices for that seller's own inventory. This authorization flow requests read-only access only.
Authorization tokens are stored locally on the seller's own machine, in a location excluded from version control. They are never transmitted to this page's host, sold, shared with any third party, or used for advertising.
Access can be revoked at any time from the eBay account's Third-Party Access settings.
