Privacy Policy
This policy explains what data Sellerio accesses through the Amazon Selling Partner API (SP-API) and Amazon Advertising API, how that data is used, and how it's protected. Sellerio does not sell seller data, and does not use it for any purpose beyond powering the account holder's own operational dashboards.
What data is accessed
| Source | Data | Purpose |
|---|---|---|
| Amazon SP-API | Orders, order line items, shipping status, ASIN/SKU catalog data | Order tracking, inventory deduction, revenue reporting |
| Amazon Advertising API | Campaign, ad group, keyword, and search-term performance (spend, clicks, sales) | Bid optimization, negative-keyword management, ad profit & loss reporting |
Sellerio does not request access to Amazon buyer personal information beyond what's required to fulfill and report on orders (e.g. shipping status), and does not use SP-API or Advertising API data for advertising, marketing, or any purpose outside the account holder's own operations.
How data is stored
- Data is stored in a private, access-controlled database. It is not publicly accessible and is not indexed or exposed by any public-facing page.
- All access to Sellerio requires an authenticated staff login with a role-based permission level; there is no public sign-up or anonymous access to any account data.
- Refresh tokens and API credentials are never exposed to the browser or included in any client-side response — only masked placeholders are ever returned to the interface once a credential is saved.
- All traffic between Sellerio and Amazon's APIs, and between a user's browser and Sellerio, is encrypted in transit (HTTPS/TLS).
Data retention
Order, inventory, and advertising data is retained for as long as the account remains active, to support historical reporting (e.g. year-over-year comparisons). Data for a disconnected or removed brand can be deleted on request.
Revoking access
An account holder can revoke Sellerio's access to their Amazon account at any time, either from within Sellerio (Remove/Disconnect on the relevant connection) or directly through Amazon — via Seller Central's Manage Apps & Services page, or the Solution Provider Portal's Manage Authorizations page. Revoking access stops all further API calls immediately; previously synced data already stored in Sellerio is not automatically deleted and can be removed on request.
Third parties
Seller data accessed through Amazon's APIs is not sold, rented, or shared with any third party. Sellerio uses the following third-party infrastructure to operate:
- Hosting — the application and database run on Hostinger Business Web Hosting.
- AI-assisted features — optional AI listing analysis and SKU analysis features send relevant product data to Anthropic's Claude API to generate recommendations; this is used only for the account holder's own listing optimization, not for any other purpose.
Changes to this policy
If this policy changes in a way that affects how Amazon seller data is handled, the "Last updated" date above will be revised and account holders will be notified.
