Privacy and account data
This development page summarizes the intended privacy posture. Final privacy policy text should be reviewed before production launch.
Seller information
Buyer-facing surfaces should show useful city or location context without exposing private seller address details unless an order flow requires it.
Proof photos
Seller-uploaded proof photos are treated as listing evidence and should only be exposed through the approved marketplace or operator review paths.
Operational records
Orders, payments, payout states, and review actions should be stored for marketplace operation, support, and auditability.
