Data usage, security and compliance

Catalogr is an analytics tool for Amazon sellers, designed in compliance with the Amazon Selling Partner API Acceptable Use Policy.

Amazon SP-API usage

• Catalogr currently uses the Amazon SP-API Catalog Items endpoint only.
• The purpose is to resolve supplier barcodes (GTIN) to Amazon ASINs.
• No other SP-API endpoints are used at this time.

Data scope

• No seller account data is accessed.
• No pricing, fees, offers, sales, or Brand Analytics data is accessed.
• No performance or competitive data is collected.

Data isolation and non-aggregation

• No cross-seller data aggregation.
• No resale or sharing of Amazon data.
• Each user only accesses their own uploaded files and outputs.

Global GTIN to ASIN cache

• Catalogr maintains a technical cache of GTIN to ASIN mappings.
• This cache contains product identifiers only.
• No seller-level or marketplace performance data is stored.
• The cache exists solely to reduce redundant SP-API calls.

Security and retention

• Passwordless authentication (magic link).
• Rate limiting and abuse prevention.
• Uploaded files and generated outputs are deleted after a limited retention period.
