What SellZen collects

SellZen processes your account email, item photos, item descriptions, listing drafts, approval records, marketplace account identifiers, encrypted marketplace tokens, and listing status. We collect only what is needed to operate, secure, and improve the service.

How information is used

We use this information to identify and value items, prepare listings, connect the marketplace account you authorize, publish only after your approval, monitor listing status, prevent duplicate actions, provide support, and protect the service from abuse.

Marketplace access

eBay sign-in occurs on eBay. SellZen never asks for or stores your eBay password. eBay provides limited authorization tokens, which SellZen encrypts and uses only for the permissions you grant. You can revoke access through eBay or request disconnection from SellZen.

Service providers

SellZen uses Cloudflare for hosting, database, and private photo storage; OpenAI sign-in for user authentication; AI providers for item analysis; and eBay when you connect an eBay account. Information is shared only as needed to provide those functions.

Retention and deletion

We retain records while your account is active and as needed for security, dispute resolution, legal obligations, and reliable marketplace operations. You may request deletion as described on the account deletion page.
