Aevyn Systems LLC ("Aevyn," "we," "us") provides risk intelligence infrastructure for Amazon sellers. We operate at aevyn.ai and deliver services through a client portal and automated monitoring system.
For questions about this policy: support@aevyn.ai
When you request a risk audit or become a client, we collect:
We do not collect payment card data directly. Payments are processed by Stripe. Stripe's privacy policy governs payment data.
When you grant us access to your Amazon Seller account through the Amazon Selling Partner API (SP-API), we access and store the following data:
Account health metrics: Order Defect Rate (ODR), Late Shipment Rate (LSR), Cancellation Rate, and other seller performance metrics published by Amazon.
Inventory data: FBA inventory levels (fulfillable, unfulfillable, reserved quantities), ASIN-level stock counts, and inventory age data.
Order data: Order identifiers, order status, fulfillment method, and order timestamps.
Financial events: Fee structures per ASIN, reimbursement events, and financial adjustment records.
Product data: ASIN identifiers and product titles and categories where available via API.
Access level: Read-only by default. We do not write to your Amazon account, place orders, or modify listings unless explicitly authorized in writing within your service agreement.
What we do not access: Individual customer names, customer addresses, customer payment data, or any personally identifiable information about your buyers.
We collect standard server logs when you visit aevyn.ai, including IP address, browser type, pages visited, and timestamps. We use this for security monitoring and infrastructure diagnostics only.
Service delivery: Detecting policy changes that affect your Amazon account, monitoring account health metrics and generating alerts, identifying unclaimed reimbursements and fee anomalies, generating risk tickets and resolution guidance, and producing your Executive Risk Digest.
Service improvement: Diagnosing system failures and improving detection accuracy. Calibrating alert thresholds against real-world enforcement patterns.
Communication: Delivering risk alerts and ticket notifications. Sending service updates and policy change briefings. Responding to your support requests.
Legal and compliance: Maintaining records required under our service agreement and responding to lawful requests from government authorities.
We do not sell your data. We do not use your data for advertising. We do not share your Amazon account data with third parties except as described in Section 4.
