Security

We never see your marketplace password.

Every account connects through the marketplace's own official authorization flow. Session credentials are encrypted, every organization's data is isolated from every other, and every connection runs over HTTPS.

How we protect your data

The principles behind every screen

Official OAuth authorization

Every Amazon account connects through Amazon's own Login with Amazon consent flow. Sellerio never asks for or stores your Seller Central password.

Live now

Encrypted token storage

Marketplace session credentials are encrypted — the kind of protection a payments processor gives card data, not stored as plain text.

Live now

Organization-level isolation

Every order, listing, credential, and API token is scoped to its organization at the database level. One org can never query another's data.

Live now

Encrypted in transit

Every connection between your browser, Sellerio, and the marketplace APIs runs over HTTPS — no unencrypted hop in between.

FAQ

Common security questions

Is my Amazon or marketplace login safe?
Yes — every connection goes through the marketplace's own official OAuth consent flow. Sellerio never sees or stores your actual password, only an authorization token scoped to what the integration needs.
Can another organization on Sellerio see my data?
No — every order, listing, credential, and token is scoped to your organization at the database level, and that isolation is enforced on every read and write, not just in the UI.
Where is my data hosted?
See the Privacy Policy for full detail on hosting and data handling — we keep that documentation current rather than duplicating it here.
Do you store payment card details?
No — subscription billing is processed by Razorpay under its own PCI-DSS compliant systems. Sellerio never receives or stores full card numbers.
