Terms of Service

Last updated: June 22, 2026

1. What MARGN.PLUS is

MARGN.PLUS is an independent analytics tool for Whatnot sellers. You upload your weekly earnings CSV from Whatnot; we parse it, compute metrics, and show you a dashboard. We are not affiliated with, endorsed by, or sponsored by Whatnot, Inc.

2. Your data

When you upload a CSV, we process and store the order rows — including buyer identifiers, order amounts, product titles, and livestream metadata — to compute your analytics. This data represents real people’s purchases and your business income. We take that seriously.

  • Your data is stored in our database, encrypted at rest by the hosting provider.
  • Only you can see your reports. Support staff may access your data to debug a problem you report.
  • You can delete any report, or your entire account, at any time from the Account page.

3. AI insights

When you generate AI insights, we send aggregated metrics derived from all of your uploaded CSVs to Anthropic's Claude API to produce personalized commentary. Before any data leaves our server, buyer @handles and product titles are replaced with anonymous positional placeholders (e.g. "buyer_a", "item_p1") — Anthropic never sees real names or identifiers. Raw CSV rows are never sent. Anthropic does not train models on API traffic. Their terms of service apply to those requests.

4. Anonymized industry reports

As a condition of using MARGN.PLUS, your data may be included in anonymized, aggregated industry reports shared with brands, retailers, or researchers. Anonymized means exactly that: no seller IDs, no buyer names, no item titles, no individually identifiable information of any kind. Only bucketed aggregates leave our system — think “total sales in a category by region,” not anything traceable to you or your buyers. If this is a dealbreaker, MARGN.PLUS may not be the right tool for you.

5. Payments

Paid plans are processed by Stripe. We don’t store your card details. Cancel anytime from the Account page; you keep access through the end of the current billing period. No refunds for partial months.

6. What you can’t do

  • Upload CSVs that aren’t yours or that you don’t have the right to upload.
  • Resell, scrape, or reverse-engineer the service.
  • Use MARGN.PLUS to stalk or harass individual buyers.

7. Disclaimers

The service is provided “as is.” We try hard to keep it running, but we can’t promise zero downtime or that the metrics perfectly match Whatnot’s own reporting. Don’t file taxes based solely on these numbers.

8. Changes + contact

We’ll email you if these terms change materially. Questions: contact support.
